ATF22LV10CQZ-30XI

Overview

The ATF22LV10CQZ-30XI is an electrically erasable programmable logic device (PLD) manufactured by Microchip Technology, formerly Atmel. It features 12 inputs and 10 I/O macrocells with a variable product term architecture providing 8 to 16 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 standby power consumption, achieving a typical standby current of 5µA. The component utilizes high-reliability CMOS Flash memory technology.

Feature Summary

• Low-voltage operation from 3.0V to 5.5V with CMOS/TTL compatibility
• Zero standby power mode via Input Transition Detection (ITD)
• High-reliability EEPROM process with 10,000 erase/write cycles
• 24-lead TSSOP surface-mount package

Applications

• Battery-powered systems requiring low standby current
• Logic replacement for legacy PAL devices
• Industrial control interfaces

Procurement Notes

Verify the ordering suffix 'XI' corresponds to the Industrial temperature range (-40°C to +85°C) and the 24X TSSOP package configuration as defined in the official datasheet. Confirm RoHS compliance status for the specific manufacturing lot. Ensure programming equipment supports the required voltage levels for this EEPLD family.

Selection Notes

Select this part when a 30 ns speed grade is sufficient for the application timing requirements. The CQZ variant offers lower active supply current compared to the CZ series. Verify that the 10 I/O macrocell capacity meets the design's logic density needs. The TSSOP package is suitable for space-constrained surface-mount designs.

Part Context

This component belongs to the ATF22LV10CQZ family of high-performance PLDs. It serves as the industrial-grade, low-power successor to the obsolete ATF22LV10CZ series. The 'CQZ' designation indicates the inclusion of Input Transition Detection circuitry for reduced power consumption.

Replacement Considerations

The ATF22LV10CZ series is obsolete and replaced by the ATF22LV10CQZ series. For direct pin-compatible upgrades, consider other ATF22LV10CQZ variants with different speed grades or packages.
