2 ATV750B(l) 0301i ? 08/01 each of the ATV750B(l) 22 logic pins can be used as an input. ten of these can be used as inputs, outputs or bi-directional 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 out- put has its own enable product term. one product term provides a common synchronous preset for all flip-flops. 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. logic options absolute maximum ratings* temperature under bias................................ -55 c to +125 c *notice: stresses beyond those listed under ? absolute maximum ratings ? may cause permanent dam- age to the device. this is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. exposure to absolute maximum rating conditions for extended periods may affect device reliability. note: 1. minimum voltage is -0.6v dc which may under- shoot to -2.0v for pulses of less than 20 ns.maximum output pin voltage is v cc + 0.75v dc which may overshoot to +7.0v for pulses of less than 20 ns. storage temperature ..................................... -65 c to +150 c voltage on any pin with respect to ground .........................................-2.0v to +7.0v (1) voltage on input pins with respect to ground during programming.....................................-2.0v to +14.0v (1) programming voltage with respect to ground .......................................-2.0v to +14.0v (1) integrated uv erase dose..............................7258 w sec/cm 2 combinatorial output combined terms separate terms registered output combined terms separate terms

9 ATV750B(l) 0301i ? 08/01 preload of registered outputs the ATV750B(l) registers are provided with circuitry to allow loading of each register asyn- chronously 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 v ih level on the i/o pin will force the reg- ister high; a v il 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. level forced on registered output pin during preload cycle select pin state register #0 state after cycle register #1 state after cycle v ih low high x v il low low x v ih high x high v il high x low
10 ATV750B(l) 0301i ? 08/01 power-up reset the registers in the ATV750B(l) is designed to reset during power-up. at a point delayed slightly from v cc crossing v rst , 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 v cc actually rises in the system, the following condi- tions are required: 1. the v cc 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 t pr . parameter description typ max units t pr power-up reset time 600 1000 ns v rst power-up reset voltage 3.8 4.5 v pin capacitance f = 1 mhz, t = 25 c (1) typ max units conditions c in 58 pf v in = 0v c out 68 pf v out = 0v
11 ATV750B(l) 0301i ? 08/01 using the ATV750B(l) many advanced features the ATV750B(l) advanced flexibility packs more usable gates into 24-pins than any other logic device. the ATV750B(l) starts 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(l) 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. programming software support as with all other atmel plds, several third-party development software products support the ATV750B(l). 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 algo- rithm 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. 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 syn- chronous 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 flip-flops 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.
12 ATV750B(l) 0301i ? 08/01 erasure characteristics the entire memory array of an ATV750B is erased after exposure to ultraviolet light at a wave- length of 2537 ? . 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/cm 2 . 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. atmel cmos plds the ATV750B utilizes an advanced 0.65-micron cmos eprom technology. this technol- ogy ? s state-of-art features are the optimum combination for plds: cmos technology provides high-speed, low-power, and high noise immunity. eprom technology is the most cos-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.
