2. Description
The Atmel® “750” architecture is 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 ATF750LVC is a highperformance CMOS (electrically-erasable) complex programmable logic device
(CPLD) that utilizes Atmel’s proven electrically-erasable technology.

1. For PLCC, pins 1, 8, 15, and 22 can
be left unconnected. For superior
performance, connect VCC to pin 1
and GND to pins 8, 15, and 22.
Each of the ATF750LVC’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 flipflop 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.

8. Bus-friendly Pin-keeper Input and I/Os
All input and I/O pins on the ATF750LVC have programmable “pin-keeper” circuits. If activated, when any pin is driven high or low and then subsequently left floating, it will stay at that
previous high or low level.
This circuitry prevents unused input and I/O lines from floating to intermediate voltage levels,
which cause unnecessary power consumption and system noise. The keeper circuits eliminate the need for external pull-up resistors and eliminate their DC power consumption.
Enabling or disabling of the pin-keeper circuits is controlled by the device type chosen in the
logic compiler device selection menu. Please refer to the software compiler table for more
details. Once the pin-keeper circuits are disabled, normal termination procedures are required
for unused inputs and I/Os.

20. Using the ATF750LVC’s Many Advanced Features
The ATF750LVC’s advanced flexibility packs more usable gates into 24-pins than any other
logic device. The ATF750LVCs start with the popular 22V10 architecture, and add several
enhanced features:
• Selectable D- and T-type Registers
Each ATF750LVC 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 ATF750LVC’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 ATF750LVC 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 ATF750LVC 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.
21. Synchronous Preset and Asynchronous Reset
One synchronous preset line is provided for all 20 registers in the ATF750LVC. 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 flip-flops are reset when the input signals received force the internal resets
high.
22. Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF750LVC 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.
