Logic Diagram
Description
The ATV750Bs 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.

Each of the ATV750B’s 22 logic pins can be used as an
input. Ten of these can be used as inputs, outputs or bidirectional 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 output has its own enable product term. One product
term provides a common synchronous preset for all flipflops. 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.

Preload of Registered Outputs
The ATV750B’s registers are provided with circuitry to
allow loading of each register asynchronously 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 VIH level on the I/O pin will force the register
high; a VIL 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.

Power Up Reset
The registers in the ATV750Bs are designed to reset during
power up. At a point delayed slightly from V CC crossing
VRST, 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 VCC actually rises in the system, the following conditions are required:
1. The VCC 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 tPR.

Using the ATV750B’s Many Advanced
Features
Synchronous Preset and
Asynchronous Reset
The ATV750B’s advanced flexibility packs more usable
gates into 24-pins than any other logic device. The
ATV750Bs start 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’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 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.
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 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 flipflops are reset when the input signals received force the
internal resets high.
Programming Software Support
As with all other Atmel PLDs, several third party development software products support the ATV750Bs. 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 algorithm 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.
10
ATV750B
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.
Erasure Characteristics
The entire memory array of an ATV750B is erased after
exposure to ultraviolet light at a wavelength of 2537 Å.
Complete erasure is assured after a minimum of 20 minutes exposure using 12,000 µW/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/cm2. 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 technology’s state of the art features are the optimum combination for PLDs:
• CMOS technology provides high speed, low power, and
high noise immunity.
• EPROM technology is the most cost 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.
