s DESCRIPTION
The MB90495G Series is a general-purpose, high-performance 16-bit microcontroller. It was designed for devices like consumer electronics, which require high-speed, real-time process control. This series features an on-chip full-CAN interface. In addition to being backwards compatible with the F2MC* family architecture, the instruction set has been expanded to add support for high-level language instructions, expanded addressing mode, and enhanced multiply/ divide and bit processing instructions. A 32-bit accumulator is also provided, making it possible to process long word (32-bit) data. The MB90495G Series peripheral resources include on chip 8/10-bit A/D converter, UART (SCI) 0/1, 8/16-bit PPG timer, 16-bit I/O timer (16-bit free-run timer, input capture 0, 1, 2, 3 (ICU) ) , and CAN controller. * : F2MC is abbreviation for Fujitsu Flexible Microcontroller.

s HANDLING DEVICES
* Make sure you do not exceed the maximum rated values (in order to prevent latch-up) . * CMOS IC chips may suffer latch-up if a voltage higher than VCC or lower than VSS is applied to an input or output pin with other than mid or high current resistance; or voltage exceeding the rating is applied across VCC and VSS. * Latch-ups can dramatically increase the power supply current, causing thermal breakdown of the device. Make sure that you do not exceed the maximum rated value of your device, in order to prevent a latch-up. * When turning the analog power supply on or off, make sure that the analog power voltage (AVCC, AVR) and analog input voltages do not exceed the digital voltage (VCC) . * Handling Unused Pins Leaving unused input pins open may cause malfunctions and latch-ups, permanently damaging the device. Prevent this by connecting it to a pull-up or pull-down resistor of no less than 2 k. Leave unused output pins open in output mode, or if in input mode, handle them in the same as input pins. * Notes on Using External Clock When using the external clock, drive pin X0 only, and leave pin X1 unconnected. See below for an example of external clock use. Example External Clock Use
X0 Open X1 MB90495G Series
* Notes on Not Using Subclock If you do not connect pins X0A and X1A to an oscillator, use pull-down handling on the X0A pin, and leave the X1A pin open. * Power Supply Pins * If your product has multiple VCC or VSS pins, pins of the same potential are internally connected in the device in order to avoid abnormal operation, including latch-up. However, you should make sure to connect the pins' external power and ground lines, in order to lower unneeded emissions, prevent abnormal operation of strobe signals due to a rise in ground levels, and maintain total output current within rated levels. * Take care to connect the VCC and VSS pins of MB90495G Series devices to power lines via the lowest possible impedance. * It is recommended that you connect a bypass capacitor of approximately 0.1 F between VCC and VSS near MB90495G Series device pins. * Crystal Oscillator Circuit * Noise in the vicinity of X0 and X1 pins could cause abnormal operations in MB90495G Series devices. Make sure to provide bypass capacitors via the shortest possible distance from X0 and X1 pins, crystal oscillators (or ceramic resonators) , and ground lines. In addition, design your printed circuit boards so as to keep X0 and X1 wiring from crossing other wiring, if at all possible. * It is strongly recommended that you provide printed circuit board artwork surrounding X0 and X1 pins within a grand area, as this should stabilize operation.
14
MB90495G Series
* A/D Converter Power-up and Analog Input Initiation Sequence * Make sure to power up the A/D converter and analog input (pins AN0 to AN7) after turning on digital power (VCC) . * Turn off digital power after turning off the A/D converter power supply and analog inputs. In this case, make sure that the voltage of AVR does not exceed AVCC (it is permissible to turn off analog and digital power simultaneously) . * Connecting Unused A/D Converter Pins If you are not using the A/D converter, set unused pins to AVCC = AVR = VCC, AVSS = VSS. * Notes for Powering Up Ensure that the voltage step-up time (between 0.2 V and 2.7 V) at power-up is no less than 50 s, in order to prevent malfunction in the built-in step-down circuit. 12 * Initialization The device contains built-in registers which are only initialized by a power-on reset. Cycle the power supply to initialize these registers. * Stabilizing the Power Supply Make sure that the VCC power supply voltage is stable. Even at the rated operating VCC power supply voltage, large, sudden changes in the voltage could cause malfunctions. As a standard for stable power supply, keep VCC ripples (peak-to-peak value) at commercial power frequencies (50 Hz to 60 Hz) to no more than 10% of the power supply voltage, and momentary surges caused by switching the power supply and other events to more than 0.1 V/ms. * If Output from Ports 0/1 Becomes Undefined After power is turned on, if the RST pin is set to "H" during step-down circuit stabilization standby (during poweron reset) , ports 0 and 1 output will be undefined. If the RST pin is set to "L", ports 0 and 1 will go into a high impedance state. Take careful note of the timing of events outlined in figures 1 and 2.

Performance of this operation, however, cannot be guaranteed. 16

Address #3* (FC0000H) FF0000H FF0000H FE0000H
* : Addresses #1 and #3 are product-specific. Note : When the internal ROM is operational, the ROM data in the upper address of bank 00 of the F2MC-16LX is visible in an image. This is called the ROM mirror function, and takes advantage of the small C compiler model. With the F2MC-16LX, the lower 16-bit address of bank FF and the lower 16-bit address of bank 00 are set identical to one another. This allows the ROM-internal table to be referenced without specifying a far pointer. For example, say the address "00C000H" is accessed. In actuality, the "FFC000H " address inside ROM will be accessed. However, as the ROM space in bank FF exceeds 48 Kbytes, the entire space cannot be viewed on bank 00's image. And so, since "FF4000H" to "FFFFFFH" ROM data will be visible on the "004000H" to "00FFFFH" image, save the ROM data table in the "FF4000H" to "FFFFFFH" space. 18

s PERIPHERAL RESOURCES
1. I/O Port
(1) Overview General-purpose (parallel) I/O ports can be used as the I/O ports. The MB90495G Series has 7 ports (49) . Each port doubles as a peripheral device I/O pin. * I/O Port Features I/O ports output data to I/O pins and load signals input to them, by means of the port data register (PDR) . Additionally, the port direction register (DDR) sets the I/O direction of the I/O pins at the bit level. Below is a description of each pin's function, and the peripheral device that shares it. * Port 0 : general-purpose I/O port/doubles as external address data bus pin * Port 1 : general-purpose I/O port/doubles as PPG timer output, input capture input, and external address data bus pin * Port 2 : general-purpose I/O port/doubles as reload timer I/O, external interrupt input pin, and external address bus pin * Port 3 : general-purpose I/O port/doubles as UART0 I/O, free-run timer, and A/D converter startup trigger pin * Port 4 : general-purpose I/O port/doubles as UART1 I/O, and CAN controller transmit/receive pin * Port 5 : general-purpose I/O port/doubles as analog input pin * Port 6 : general-purpose I/O port/doubles as external interrupt input pin

3. Watchdog Timer
The watchdog timer is a 2-bit timer used as a count clock for the timer-based or clock timer. If the counter is not cleared within the interval time, it resets the CPU. * Watchdog Timer Function * The watchdog timer is a timer counter used to deal with runaway programs. Once the watchdog timer is launched, it is necessary to keep clearing its counter within the specified interval. If the specified interval passes without the watchdog timer counter being cleared, the CPU will be reset. This feature is called the watchdog timer. * The watchdog timer interval traces back to the clock interval input as the count clock. A watchdog reset is generated for the smallest to largest times. * The clock source output destination is set by the watchdog clock selection bit of the clock timer control register (WTC : WDCS) . * The watchdog timer interval is set time-base timer output selection bit/clock timer output selection bit of the watchdog timer control register (WDTC : WT1, WT0) .

4. 16-bit I/O Timer
The 16-bit I/O timer is a complex module comprising one 16-bit free-run timer, and two input capture units (4 input pins) . Clock interval input signals and pulse widths can be measured based on the 16-bit free-run timer. * 16-bit I/O Timer Configuration The 16-bit I/O timer is made up of the following modules : * One 16-bit free-run timer * Two input capture units (each unit having 2 input pins) * 16-bit I/O Timer Function (1) 16-bit free-run timer function The 16-bit free-run timer consists of a 16-bit up counter, a time counter control status register, and prescaler. The 16-bit up counter counts up in synchronization with a fraction of the machine clock. * The count clock can be set to one of four fractions of the machine clock. The external clock signals input to the 16-bit free-run timer clock input pin (FRCK) can be used as the count clock. * Interrupts can be generated in response to counter value overflows. * Interrupts launch the extended intelligent I/O service (EI2OS) . * The count value of the 16-bit free-run timer can be cleared to "0000H" by either a reset, or software clear via the timer count clear bit (TCCS : CLR) . * The count value of the 16-bit free-run timer is output to the input capture, and used as the base time for capture operation. (2) Input Capture Function When the input capture detects that an external signal edge has been input to an input pin, it stores the count value of the 16-bit free-run timer in the input capture data register, for the point at which the edge was detected. The input capture consists of an input capture register corresponding to four I/O pins, an input capture control status register, and an edge detection circuit. * When an edge is detected, either rising, falling, or both can be selected. * An interrupt request can be generated to the CPU when an input signal edge is detected. * Interrupts launch the extended intelligent I/O service (EI2OS) . * Since the input capture has four pairs of input pins and input capture data registers, it can measure up to 4 phenomena. * Block Diagram of 16-bit I/O Timer

13. ROM Correction Function
In the case that the address of the instruction after the one that a program is currently processing matches the address configured in the detection address configuration register, the program forces the next instruction to be processed into an INT9 instruction, and branches to the interrupt process program. Since processing can be conducted using INT9 interrupts, programs can be repaired using batch processing. * Overview of the ROM Correction Function * The address of the instruction after the one that a program is currently processing is always stored in an address latch via the internal data bus. ROM correction constantly compares the address stored in the address latch with the one configured in the detection address configuration register. If the two compared addresses match, the CPU forcibly changes this instruction into an INT9 instruction, and executes an interrupt processing program. * There are two detection address configuration registers : PADR0 and PADR1. Each register provides an interrupt enable bit. This allows you to individually configure each register to enable/prohibit the generation of interrupts when the address stored in the address latch matches the one configured in the detection address configuration register. * ROM Correction Block Diagram

* Overview There are three methods available for writing/deleting data to/from flash memory : 1. Parallel writer 2. Serial dedicated writer 3. Program runtime write/delete * Overview of 512-Kbit flash memory 512-Kbit flash memory is arrayed in bank FFH on the CPU memory map. The flash memory interface circuit provides read and program access from the CPU. Since instructions from the CPU are carried out via the flash memory interface circuit, flash memory can be overwritten at the implementation level. This allows you to efficiently improve programs and data. * Features of 512-Kbit Flash Memory * 128 KWords x 8-bit/64 KWords x 16-bit (16 K + 8 K + 8 K + 32 K) sector architecture * Auto program algorithm (Embedded AlgorithmTM : same as MBM29LV200) * On-chip delete suspend/delete resume functions * Data polling, write/delete completion detection through toggle bit * Write/delete completion detection from CPU overwrite * Sector-specific deletion available (sectors can be combined as desired) * Write/delete iterations (minimum) : 10,000 Embedded AlgorithmTM is a trademark of Advanced Micro Device. Notes : There is no function to read the manufacture or device code. These codes also cannot be accessed through commands. * Flash memory write/delete * It is not possible to simultaneously write to and read from flash memory. * When writing to or deleting from flash memory, first copy the program residing in flash memory into RAM, then execute the program copied into RAM. This will allow you to write to flash memory.

Sudden changes in the power supply voltage may cause a power-on reset. To change the power supply voltage while the device is in operation, it is recommended that you raise the voltage at a steady rate, in order to suppress fluctuations (see figure below). In this case, perform this operation when the PLL clock is not being used. If, however, the voltage falling speed is no more than 1 V/s, it is permissible to perform this operation while using the PLL clock.

6. A/D Converter Glossary
Resolution Linearity error : Analog changes that are identifiable with the A/D converter : The deviation of the straight line connecting the zero transition point ( "00 0000 0000" "00 0000 0001" ) with the full-scale transition point ( "11 1111 1110" "11 1111 1111" ) from actual conversion characteristics. Differential linearity error : The deviation of input voltage needed to change the output code by 1 LSB from the ideal value. Total error : The difference between the actual value and the theoretical value, which includes zero-transition error/full-scale transition error, linearity error, and differential linearity error.

7. Notes on Using A/D Converter
Select the output impedance value for the external circuit of analog input according to the following conditions : External circuit output impedance values of about 5 k or lower are recommended. If external capacitors are used, a capacitance of several thousand times the internal capacitor value is recommended in order to minimize the effect of voltage distribution between the external and internal capacitor. If the output impedance of the external circuit is too high, the sampling time for analog voltages may not be sufficient (sampling period = 2.00 s @ machine clock of 16 MHz) . * Model Analog Input Circuit
