2 / 16 page ATF750C(L) 2 guarantee fast in-system performance. The ATF750C(L) is a high-performance CMOS (electrically-erasable) complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable technology. Each of the ATF750C(L)’s 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 config- urable 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. There are two sum terms per output, providing added flexibility. A variable format is used to assign between four to eight product terms per sum term. 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 individu- ally 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 flip- flops. Register preload functions are provided to simplify testing. All registers automatically reset upon power-up. The ATF750C(L) is a low-power device with speeds as fast as 15 ns. The ATF750C(L) provides the optimum low-power CPLD solution. This device significantly reduces total system power, thereby allowing battery- powered operations. DC and AC Operating Conditions All members of the family are specified to operate in either one of two voltage ranges. Parameters are specified as noted to be either 2.7V to 3.6V, 5V ± 5% or 5V ± 10%. 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. Max- imum 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) 5V Operation Commercial -7.5, -10, -15 Industrial -10, -15 Operating Temperature (Ambient) 0°C - 70°C-40°C - +85°C V CC Power Supply 5V ± 5% 5V ± 10% |
