Description
The ATV750B(L) 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.

Each of the ATV750B(L) 22 logic pins can be used as an input. Ten of these can be used as
Combined TermsSeparate Terms
inputs, outputs or bi-directional I/O pins. Each flip-flop is individually configurable as either Dor 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 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.
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.

Using the
ATV750B(L)
Many Advanced
Features
Programming
Software
Support
The ATV750B(L) advanced flexibility packs more usable gates into 24-pins than any other
logic device. The ATV750B(L) starts 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(L) 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.
As with all other Atmel PLDs, several third-party development software products support the
ATV750B(L). 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 flipflops 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 LogicDevelopment Tools section for a complete PLD software and programmer listing.
Synchronous
Preset and
Asynchronous
Reset
Security Fuse
Usage
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 flip-flops are reset when the input signals received force the internal resets
high.
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
lamps at other intensity ratings can be calculated from the minimum integrated erasure dose
of 15 W

Atmel CMOS
PLDs
The ATV750B utilizes an advanced 0.65-micron CMOS EPROM technology. This technology’s state-of-art features are the optimum combination for PLDs:
•CMOS technology provides high-speed, low-power, and high noise immunity.
•EPROM technology is the most cos-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.
