1. Description

The ATF22LV10CZ/CQZ is a high-performance CMOS (electrically erasable) pro-

grammable logic device (PLD) that utilizes Atmel’s proven electrically erasable Flash

memory technology and provides 25 ns speed with standby current of 25 µA maxi-

mum. All speed ranges are specified over the 3.0V to 5.5V range for industrial and

commercial temperature ranges.

The ATF22LV10CZ/CQZ provides a low-voltage and edge-sensing “zero” power

CMOS PLD solution with “zero” standby power (5 µA typical). The

ATF22LV10CZ/CQZ powers down automatically to the zero power mode through

Atmel’s patented Input Transition Detection (ITD) circuitry when the device is idle. The

ATF22LV10CZ/CQZ is capable of operating at supply voltages down to 3.0V. Pin

“keeper” circuits on input and output pins hold pins to their previous logic levels when

idle, which eliminate static power consumed by pull-up resistors. The “CQZ” combines

this low high-frequency ICC of the “Q” design with the “Z” feature.

The ATF22LV10CZ/CQZ macrocell incorporates a variable product term architecture.

Each output is allocated from 8 to 16 product terms which allows highly complex logic

functions to be realized. Two additional product terms are included to provide syn-

chronous reset and asynchronous reset. These additional product terms are common

to all 10 registers and are automatically cleared upon power-up. Register Preload sim-

plifies testing. A security fuse prevents unauthorized copying of programmed fuse

patterns.
