2. Pin Configurations
The ATF750C(L)s are twice as powerful as most other 24-pin programmable logic devices.
Increased product terms, sum terms, flip-flops and output logic configurations
translate into more usable gates. High-speed logic and uniform predictable delays guarantee
fast in-system performance. The ATF750C(L) is a high-performance CMOS (electrically-eras-
able) 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 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. 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 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
flip-flops. Register preload functions are provided to simplify testing. All registers automatically
reset upon power-up.
The ATF750CL is a low-power device with speeds as fast as 15 ns. The ATF750CL provides the
optimum low-power CPLD solution. This device significantly reduces total system power,
thereby allowing battery-powered operations.
