ATF22LV10CQZ-30JI

Overview

The ATF22LV10CQZ-30JI 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 supports industrial temperature applications from -40°C to +85°C. Key electrical specifications include a maximum propagation delay of 30ns for non-registered outputs, a typical standby current of 5µA enabled by Input Transition Detection, and a maximum clocked power supply current of 60mA at 15MHz. It utilizes Flash memory technology allowing for 10,000 erase/write cycles.

Feature Summary

• Low-power operation with 'Zero' standby power mode (5µA typical) via Input Transition Detection circuitry
• Industrial temperature range (-40°C to +85°C) with 3.0V to 5.5V operating voltage
• High-reliability CMOS process featuring 20-year data retention and 2,000V ESD protection
• CMOS- and TTL-compatible I/Os with 5V tolerant inputs and internal pin keeper circuits

Applications

• Battery-powered systems requiring low standby current
• Complex logic replacement for legacy 24-pin PAL devices
• State machine initialization utilizing automatic power-up reset
• General-purpose digital logic design in industrial environments

Procurement Notes

Verify the package type corresponding to the suffix 'J', which indicates a 28-lead Plastic J-leaded Chip Carrier (PLCC). Confirm that the 'I' suffix denotes the Industrial temperature grade (-40°C to +85°C). Ensure programming equipment supports the specific EEPLD architecture and verify RoHS compliance status if required for the assembly process.

Selection Notes

Select this component when an industrial-grade PLD with low active and standby power consumption is required. The 30ns speed grade is suitable for applications up to approximately 33.3 MHz. Consider the PLCC package availability against surface-mount alternatives like SOIC or TSSOP if board space is constrained. Ensure the design accounts for the 5V tolerant input characteristics if interfacing with mixed-voltage logic levels.

Part Context

This part belongs to the ATF22LV10CQZ family, which serves as the low-voltage equivalent to the Atmel ATF22V10CZ. The 'CQZ' designation specifically combines the low-frequency ICC of the 'Q' design with the 'Z' feature set. The standard ATF22LV10CZ has been marked obsolete and replaced by the CQZ variants in green package offerings.

Replacement Considerations

The ATF22LV10CZ series is obsolete and replaced by the ATF22LV10CQZ series. For direct functional replacements within the same family, consider the ATF22LV10CQZ-30SU (SOIC package) or ATF22LV10CQZ-30XU (TSSOP package) for different mounting styles while maintaining identical electrical performance.
