ATF22LV10CQZ-30PI

Overview

The ATF22LV10CQZ-30PI is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology, originally designed by Atmel. It features a high-performance CMOS architecture with 12 inputs and 10 I/O macrocells, providing 8 to 16 product terms per output. The device operates within a 3.0V to 5.5V supply range and delivers a maximum propagation delay of 30 ns. It incorporates Input Transition Detection (ITD) for zero-power standby mode, achieving a typical standby current of 5µA. The component utilizes Flash memory technology, supporting 10,000 erase/write cycles and 20-year data retention.

Feature Summary

• Low-voltage operation from 3.0V to 5.5V with CMOS/TTL-compatible I/O
• Input Transition Detection (ITD) circuitry enables automatic zero-power standby mode
• High-reliability CMOS process with 200mA latch-up immunity and 2,000V ESD protection
• Variable product term architecture with synchronous/asynchronous reset capabilities

Applications

• Battery-powered systems requiring low standby power consumption
• Logic replacement for legacy 24-pin PAL devices
• Industrial control interfaces operating in commercial and industrial temperature ranges

Procurement Notes

Verify the package type 'PI' corresponds to the 24-pin Plastic Dual Inline Package (PDIP). Confirm RoHS compliance status as green package options are available. Check export restrictions if applicable. Ensure programming equipment supports EEPLD architectures. Validate that the -30 speed grade meets system timing requirements.

Selection Notes

Select this part for designs needing low active and standby power in a 3.0V to 5.5V environment. The -30 suffix indicates a 30ns max propagation delay suitable for moderate-speed logic. Compare against the obsolete ATF22LV10CZ-25 series; the CQZ variant offers lower power consumption. Ensure the PDIP package fits the PCB layout constraints compared to surface-mount alternatives like SOIC or TSSOP.

Part Context

This component belongs to the ATF22LV10CQZ family, which serves as the low-voltage successor to the standard voltage ATF22V10C series. The 'CQZ' designation specifically denotes the inclusion of Input Transition Detection for reduced power. The 'PI' suffix identifies the Industrial temperature range (-40°C to +85°C) and the PDIP package style. This model replaces the older ATF22LV10CZ-25PI in many applications due to improved power efficiency.

Replacement Considerations

The ATF22LV10CZ series is obsolete and replaced by the ATF22LV10CQZ series. For direct pin-compatible replacements with similar electrical characteristics, consider the ATF22LV10CQZ-30SI (SOIC) or ATF22LV10CQZ-30XI (TSSOP) variants. Verify that the target substitute maintains the same 30ns speed grade and industrial temperature rating.
