Description
The ATF20V8B is a high-performance CMOS (electrically-
erasable) programmable logic device (PLD) that 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
