ATF22LV10CQZ-30JC

Overview

The ATF22LV10CQZ-30JC is a high-performance CMOS electrically erasable programmable logic device (PLD) featuring Atmel Flash memory technology. It operates within a 3.0V to 5.5V supply range and delivers a maximum propagation delay of 30ns. The device incorporates Input Transition Detection (ITD) circuitry for automatic power-down, achieving a maximum standby current of 25µA. It provides 12 inputs and 10 I/O macrocells with variable product term architecture. The component supports commercial temperature ranges (0°C to +70°C) and includes features such as synchronous/asynchronous reset, register preload, and a security fuse.

Feature Summary

• Low-voltage operation from 3.0V to 5.5V with zero-power standby mode via ITD
• High-reliability CMOS process with 10,000 erase/write cycles and 20-year data retention
• Variable product term architecture allowing 8 to 16 terms per output plus common reset terms
• CMOS and TTL compatible inputs/outputs with 5V tolerant input pins

Applications

• Battery-powered systems requiring low standby power
• Replacement for legacy 24-pin PAL devices
• Complex digital logic implementation in industrial and commercial environments

Procurement Notes

Verify the specific package suffix 'JC' corresponds to the 28-lead Plastic J-leaded Chip Carrier (PLCC) in the commercial temperature range. Confirm that the source document identifies this part as a replacement for the obsolete ATF22LV10CZ series. Ensure programming hardware supports the required JEDEC file generation for preload and security fuse operations.

Selection Notes

Select this model when a 30ns speed grade is sufficient and low power consumption is critical. The CQZ variant offers lower high-frequency ICC compared to the CZ series. Choose the JC suffix for PLCC packaging needs. Verify that the application environment stays within the 0°C to +70°C commercial temperature range; otherwise, an Industrial grade part is required.

Part Context

This component belongs to the ATF22LV10CQZ family, which serves as the low-voltage equivalent to the Atmel ATF22V10CZ. The ATF22LV10CZ is explicitly marked as Not Recommended for New Design and has been replaced by the CQZ variants. The 'CQZ' designation indicates the combination of low high-frequency ICC and Green Package options.

Replacement Considerations

The ATF22LV10CZ-25JC is the direct predecessor and is obsolete. The ATF22LV10CQZ-30JC replaces it with updated electrical characteristics and packaging compliance. No other cross-model substitutes are documented in the provided datasheet.
