Each of the ATV750B's 22 logic pins can be used as an input. Ten of these can be used as inputs, outputs or bidirectional I/O pins. Each flip-flop is individually configurable as either D- or T-type. Each flip-flop output is fed back into the array independently. This allows burying of all the sum terms and flip-flops. There are 171 total product terms available. A variable format is used to assign between four to eight product terms per sum term. There are two sum terms per output, providing added flexibility. Much more logic can be replaced by this device than by any other 24-pin PLD. With 20 sum terms and flip-flops, complex state machines are easily implemented with logic to spare.
Product terms provide individual clocks and asynchronous resets for each flip-flop. Each flip-flop may also be individually configured to have direct input pin controlled clocking. Each output has its own enable product term. One product term provides a common synchronous preset for all flipflops. Register preload functions are provided to simplify testing. All registers automatically reset upon power up. The ATV750BL is a low power device with speeds as fast as 15 ns. The ATV750BL provides the optimum low power PLD solution, with full CMOS output levels. This device significantly reduces total system power, thereby allowing battery-powered operation.

Preload of Registered Outputs
The ATV750B's registers are provided with circuitry to allow loading of each register asynchronously with either a high or a low. This feature will simplify testing since any state can be forced into the registers to control test sequencing. A VIH level on the I/O pin will force the register high; a VIL will force it low, independent of the output polarity. The PRELOAD state is entered by placing a 10.25V to 10.75V signal on pin 8 on DIPs, and lead 10 on SMDs. When the clock term is pulsed high, the data on the I/O pins is placed into the register chosen by the Select Pin.

Register #0 State after cycle High Low X X
Register #1 State after cycle X X High Low
Power Up Reset
The registers in the ATV750Bs are designed to reset during power up. At a point delayed slightly from V CC crossing VRST, all registers will be reset to the low state. The output state will depend on the polarity of the output buffer. This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the uncertainty of how VCC actually rises in the system, the following conditions are required: 1. The VCC rise must be monotonic, 2. After reset occurs, all input and feedback setup times must be met before driving the clock terms or pin high, and 3. The clock pin, or signals from which clock terms are derived, must remain stable during tPR.

Using the ATV750B's Many Advanced Features
The ATV750B's advanced flexibility packs more usable gates into 24-pins than any other logic device. The ATV750Bs start with the popular 22V10 architecture, and add several enhanced features: * Selectable D- and T-Type Registers Each ATV750B flip-flop can be individually configured as either D- or T-type. Using the T-type configuration, JK and SR flip-flops are also easily created. These options allow more efficient product term usage. * Selectable Asynchronous Clocks Each of the ATV750B's flip-flops may be clocked by its own clock product term or directly from Pin 1 (SMD Lead 2). This removes the constraint that all registers must use the same clock. Buried state machines, counters and registers can all coexist in one device while running on separate clocks. Individual flip-flop clock source selection further allows mixing higher performance pin clocking and flexible product term clocking within one design. * A Full Bank of Ten More Registers The ATV750B provides two flip-flops per output logic cell for a total of 20. Each register has its own sum term, its own reset term and its own clock term. * Independent I/O Pin and Feedback Paths Each I/O pin on the ATV750B has a dedicated input path. Each of the 20 registers has its own feedback terms into the array as well. This feature, combined with individual product terms for each I/O's output enable, facilitates true bi-directional I/O design.
Synchronous Preset and Asynchronous Reset
One synchronous preset line is provided for all 20 registers in the ATV750B. The appropriate input signals to cause the internal clocks to go to a high state must be received during a synchronous preset. Appropriate setup and hold times must be met, as shown in the switching waveform diagram. An individual asynchronous reset line is provided for each of the 20 flip-flops. Both master and slave halves of the flipflops are reset when the input signals received force the internal resets high.
Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATV750B fuse patterns. Once the security fuse is programmed, all fuses will appear programmed during verify. The security fuse should be programmed last, as its effect is immediate.
Erasure Characteristics
The entire memory array of an ATV750B is erased after exposure to ultraviolet light at a wavelength of 2537 A. Complete erasure is assured after a minimum of 20 minutes exposure using 12,000 W/cm 2 intensity lamps spaced one inch away from the chip. Minimum erase time for lamps at other intensity ratings can be calculated from the minimum integrated erasure dose of 15 W*sec/cm2. To prevent unintentional erasure, an opaque label is recommended to cover the clear window on any UV erasable PLD which will be subjected to continuous fluorescent indoor lighting or sunlight.
Programming Software Support
As with all other Atmel PLDs, several third party development software products support the ATV750Bs. Several third party programmers support the ATV750B as well. Additionally, the ATV750B may be programmed to perform the ATV750/L's functional subset (no T-type flip-flops or pin clocking) using the ATV750/L JEDEC file. In this case, the ATV750B becomes a direct replacement or speed upgrade for the ATV750/L. The ATV750/L programming algorithm is different from the ATV750B algorithm. Choose the appropriate device in your programmer menu to ensure proper programming. Please refer to the Programmable Logic Development Tools section for a complete PLD software and programmer listing.
Atmel CMOS PLDs
The ATV750B utilizes an advanced 0.65-micron CMOS EPROM technology. This technology's state of the art features are the optimum combination for PLDs: * CMOS technology provides high speed, low power, and high noise immunity. * EPROM technology is the most cost effective method for producing PLDs - surpassing bipolar fusible link technology in low cost, while providing the necessary reprogrammability. * EPROM reprogrammability, which is 100% tested before shipment, provides inherently better programmability and reliability than one-time fusible PLDs.
