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 configu-
rations translate into more usable gates. High-speed logic and uniform, predictable
delays guarantee fast in-system performance. The ATF750LVC is a high-performance

CMOS (electrically-erasable) complex programmable logic
device (CPLD) that utilizes Atmel’s proven electrically-eras-
able technology.
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.
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 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.
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.
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

Bus-friendly Pin-keeper Input and I/Os
Input Diagram
All input and I/O pins on the ATF750LVC(L) have program-
mable “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.
VCC
This circuitry prevents unused input and I/O lines from
floating to intermediate voltage levels, which cause unnec-
essary power consumption and system noise. The keeper
circuits eliminate the need for external pull-up resistors and
eliminate their DC power consumption.

OPTION
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.

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:
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.
• 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.
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.
• 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.
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.
• 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.

Using “C” Product for Industrial
Because the VCC conditions are the same for commercial and industrial for 3.3V products, and there is only 15°C difference
at the high end of the temperature range, there is very little risk in using “C” devices for industrial applications. Just de-rate
ICC by 15%.
