ATF22V10CQZ-20JC

Overview

The ATF22V10CQZ-20JC is a high-performance CMOS electrically erasable programmable logic device (PLD) manufactured by Microchip Technology. It features 12 inputs and 10 I/O macrocells with a maximum pin-to-pin propagation delay of 20 ns. The device operates at 5V ±10% and supports industrial temperature ranges from -40°C to +85°C. It utilizes advanced Flash memory technology, offering zero standby power via Input Transition Detection (ITD), 100 erase/write cycles, and 20-year data retention.

Feature Summary

• Maximum 20 ns pin-to-pin delay with 10 macrocells
• Zero standby power mode (100 µA max) using ITD circuitry
• CMOS and TTL compatible inputs and outputs
• Industrial temperature range (-40°C to +85°C)

Applications

• Direct replacement for 22V10 family PLDs
• Complex logic function realization in digital systems
• State machine initialization with power-up reset

Procurement Notes

Verify the package type corresponds to the 'J' suffix, indicating a 28-lead Plastic J-leaded Chip Carrier (PLCC). Confirm that the 'C' designation aligns with commercial speed grades used within industrial temperature environments if required. Ensure programming hardware supports the specific Flash memory architecture for reliable erasing and writing operations.

Selection Notes

Select this component when a 20 ns delay specification is required for 24-pin PAL-compatible designs. The CQZ variant combines low high-frequency supply current with zero-power standby capabilities. Verify that the system voltage remains within the 5V ±10% range to ensure proper operation of the Input Transition Detection circuitry and output drive strengths.

Part Context

This part belongs to the ATF22V10CQZ series, which serves as a superset of the generic 22V10 architecture. The ATF22V10CZ model is obsolete and replaced by the ATF22V10CQZ. The 'JC' suffix specifically denotes the 20 ns speed grade packaged in a 28-lead PLCC format intended for commercial speed performance but qualified for industrial temperature applications.
