ATF22V10CZ
Preliminary
Description
The ATF22V10CZ is a high performance CMOS (Electrically Erasable) Programmable Logic Device (PLD) which utilizes Atmel’s proven electrically erasable Flash memory technology. Speeds down to 12 ns with zero standby power dissipation are offered. All speed ranges are specified over the full 5V ±10% range for industrial temperature ranges; 5V ± 5% for commercial range 5-volt devices.

The ATF22V10CZ provides a “zero” power CMOS PLD
solution with 5V operating voltages. The ATF22V10CZ
powers down automatically to th e zero power mode
through Atmel’s patented Input Transition Detection (ITD)
circuitry when the device is idle. The ATF22V10CZ has
an edge-sensing power down feature, offering “zero” (25
µA worst case) standby power. This feature allows the
user to manage total system power to meet specific application requirements and enhance reliability. Pin “ keeper”
Absolute Maximum Ratings*
circuits on input and output pins eliminate static power
consumed by pull-up resistors.
The ATF22V10CZ incorporates a superset of the generic
architectu res, which allows direc t replacement of the
22V10 family and most 24-pin combinatorial PLDs. Ten
outputs are each allocated 8 to 16 product terms. Three
different modes of operation, configured automatically
with software, allow highly complex logic functions to be
realized.

This is a stress rating only and functional operation of the
device at these or an y ot he r con ditions beyond those indicated in the oper ational secti ons of this specification is not
implied. Exposure to absolute maxi mum rating conditions
for extended periods may affect device reliability.

ATF22V10CZ
Functional Logic Diagram Description
The Functional Logic Diagram describes the
ATF22V10CZ architecture.
The ATF22V10CZ has 12 inputs and 10 I/O macrocells.
Each macrocell can be configured into one of four output
configurations: active high/low, registered/combinatorial
output. The universal architecture of the ATF22V10CZ
can be programmed to emulate most 24-pin PAL devices.
DC Characteristics
ATF22V10CZ
Unused product terms are automatically disabled by the
compiler to decrease power consumption. A Security
Fuse, when programmed, protects the contents of the
ATF22V10CZ. Eight bytes (64 fuses) of User Signature
are accessible to the user for purposes such as storing
project nam e, part number, revision or date. The User
Signature is accessible regardless of the state of the Security Fuse.
