ATF22LV10CQZ-30SC

Overview

The ATF22LV10CQZ-30SC is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology, utilizing Atmel Flash memory technology. It features a 3.0V to 5.5V operating range and a maximum propagation delay of 30 ns. The device includes 12 inputs and 10 I/O macrocells with variable product term architecture. It offers low standby power consumption of 25 µA maximum via Input Transition Detection. The component operates within a commercial temperature range of 0°C to +70°C and is housed in a 24-lead SOIC package.

Feature Summary

• Low-voltage operation from 3.0V to 5.5V with zero-power standby mode
• CMOS and TTL-compatible inputs and outputs with 5V tolerance
• Input and I/O pin keeper circuits maintain previous logic states when idle
• High-reliability CMOS process with 10,000 erase/write cycles and 20-year data retention

Applications

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

Procurement Notes

Verify the specific suffix 'SC' against official ordering tables, as standard documentation lists 'SU' for industrial and 'JC/JI/PC/PI/SI/XI' variants. Confirm RoHS compliance status and lead-free packaging availability for the specific lot. Ensure programming hardware supports the EEPLD architecture and security fuse settings.

Selection Notes

Select this part for applications needing low power consumption during idle states due to the Input Transition Detection feature. The 30 ns speed rating suits moderate frequency logic functions up to 33.3 MHz. Consider the SOIC package for surface mount assembly. Verify that the 10 macrocell capacity meets the logic complexity requirements of the design.

Part Context

This component belongs to the ATF22LV10CQZ family, which serves as the low-voltage equivalent to the Atmel ATF22V10CZ. The 'CQZ' designation indicates the inclusion of Input Transition Detection circuitry for reduced power consumption. The ATF22LV10CZ series is generally being replaced by the CQZ variants in green package options.

Replacement Considerations

The ATF22LV10CZ series is obsolete and replaced by the ATF22LV10CQZ series. For direct functional replacement, consider ATF22LV10CQZ-30SU for industrial temperature ranges or other CQZ variants depending on package preference.
