ATF20V8B

Description

The ATF20V8B is a high performance CMOS (Electrically

Erasable) Programmable Logic Device (PLD) which utilizes

Atmel’s proven electrically erasable Flash memory technol-

ogy. Speeds down to 7.5 ns and power dissipation as low

as 10 mA are offered. All speed ranges are specified over

the full 5V

± 10% range for industrial temperature ranges,

and 5V

± 5% for commercial temperature ranges.

Several low power options allow selection of the best solu-

tion for various types of power-limited applications. Each of

these options significantly reduces total system power and

enhances system reliability.

The ATF20V8Bs incorporate a superset of the generic

architectures, which allows direct replacement of the 20R8

family and most 24-pin combinatorial PLDs. Eight outputs

are each allocated eight product terms. Three different

modes of operation, configured automatically with soft-

ware, allow highly complex logic functions to be realized.

Absolute Maximum Ratings*

Temperature Under Bias ................................ -55°C to +125°C

*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age to the device. This is a stress rating only and

functional operation of the device at these or any

other conditions beyond those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

conditions for extended periods may affect device

reliability.

Note:

1.

Minimum voltage is -0.6V DC which may under-

shoot to -2.0V for pulses of less than 20 ns.Maxi-

mum output pin voltage is V

may overshoot to 7.0V for pulses of less than 20

ns.
