VCC is internally connected to the voltage regulator output VREG. 1.1.3 VREG Output from the internal voltage regulator. Internally connected to VCC. 1.1.4 GND Ground 1.1.5 Port B (PB2:PB0) Port B is a low-voltage 3-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running. Port B also serves the functions of various special features of the ATmega4HVD/8HVD. 1.1.6 Port C (PC1:PC0) Port C is a High-voltage open-drain 2 bit bi-directional I/O port. Port C also serves the functions of various special features of the ATmega4HVD/8HVD. 1.1.7 OC High voltage output to drive Charge FET (optional). 1.1.8 OD High voltage output to drive Discharge FET. 1.1.9 NI Negative input from the battery protection resistor. 1.1.10 PV1 Input from battery cell to ADC. 1.1.11 BATT Input for detecting when a charger is connected. 1.1.12 RESET/dw Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running. Shorter pulses are not guaranteed to generate a reset. This pin is also used as debugWIRE communication pin. 3 8052BS-AVR-09/08 ATmega4HVD/8HVD 2. Overview The ATmega4HVD/8HVD is a monitoring and protection circuit for 1-cell Li-ion applications with focus on high security/authentication, low cost and high utilization of the cell energy. The device contains secure authentication features as well as autonomous battery protection during charging and discharging. The External Protection Input can be used to implement other battery protection mechanisms using external components, e.g. protection against chargers with too high charge voltage can be easily implemented with a few low cost passive components. The feature set makes the ATmega4HVD/8HVD a key component in any system focusing on high security, battery protection, high system utilization and low cost. Figure 2-1.

The regulator capabilities, combined with a extremely low power consumption in the power saving modes, greatly enhances the cell energy utilization compared to existing solutions. The chip utilizes Atmel's Deep Under-voltage Recovery (DUVR) mode that supports precharging of deeply discharged battery cells without using a separate Pre-charge FET. An enhanced start-up scheme allows the chip to operate correctly even with only Discharge FET connected. This makes it possible to further reduce system cost for applications that do not require Charge Over-current protection. The ATmega4HVD/8HVD contains a 10-bit ADC for cell voltage measurements. The ADC is also used to monitor the on-chip temperature. Temperature is measured by the integrated Voltage Reference, which contains a built-in temperature sensor. ATmega4HVD/8HVD con4 8052BS-AVR-09/08 ATmega4HVD/8HVD tains a high-voltage tolerant, open-drain IO pin that supports serial communication. Programming can be done in-system using the 4 General Purpose IO ports that support SPI programming The MCU includes 4K/8K bytes of In-System Programmable Flash with Self-programming capabilities, 256 bytes EEPROM, 512 bytes SRAM, 32 general purpose working registers, 4 general purpose I/O lines, debugWIRE for On-chip debugging and SPI for In-system Programming, two flexible Timer/Counters with Input Capture, internal and external interrupts, a 10-bit ADC for measuring the cell voltage and on-chip temperature, a programmable Watchdog Timer with wake-up capabilities, and software selectable power saving modes. The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The device is manufactured using Atmel's high voltage high density non-volatile memory technology. The On-chip ISP Flash allows the program memory to be reprogrammed In-System, by a conventional non-volatile memory programmer or by an On-chip Boot program running on the AVR core. The ATmega4HVD/8HVD AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, and On-chip Debugger. The ATmega4HVD/8HVD is a low-power CMOS 8-bit microcontroller based on the AVR architecture. It is part of the AVR Smart Battery family that provides secure authentication, highly accurate monitoring and autonomous protection for Lithium-ion battery cells. 3.

For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written. 2. I/O registers within the address range $00 - $1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions. 3. Some of the status flags are cleared by writing a logical one to them. Note that the CBI and SBI instructions will operate on all bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions work with registers 0x00 to 0x1F only. 4. When using the I/O specific commands IN and OUT, the I/O addresses $00 - $3F must be used. When addressing I/O registers as data space using LD and ST instructions, $20 must be added to these addresses. The ATmega4HVD/8HVD is a complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instructions. For the Extended I/O space from $60 - $FF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used. 9 8052BS-AVR-09/08 ATmega4HVD/8HVD 6.
