ATF22LV10CZ-25PI

Overview

The ATF22LV10CZ-25PI 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 operates within the industrial temperature range of -40°C to +85°C. The component provides 12 inputs and 10 I/O macrocells with a maximum propagation delay of 25ns. It incorporates Input Transition Detection (ITD) for zero-power standby mode, achieving a maximum standby current of 25µA. The device is housed in a 24-pin Plastic Dual Inline Package (PDIP).

Feature Summary

• Low-voltage operation from 3.0V to 5.5V with CMOS/TTL compatibility.
• Zero-power standby mode via Input Transition Detection (ITD), limiting standby current to 25µA maximum.
• High-reliability CMOS process ensuring 20-year data retention and 10,000 erase/write cycles.
• Variable product term architecture allowing 8 to 16 terms per output plus common reset terms.

Applications

• Battery-powered systems requiring low standby power consumption.
• Logic replacement for standard PAL devices in industrial environments.
• Complex state machine implementations utilizing synchronous preset and asynchronous reset capabilities.

Procurement Notes

Verify that the ordering suffix 'PI' corresponds to the Industrial temperature range (-40°C to +85°C) and the 24-pin PDIP package. Confirm RoHS compliance status as the datasheet indicates leaded parts may be obsolete or replaced by green package options. Ensure programming hardware supports the specific Flash memory architecture for reliable erasing and writing.

Selection Notes

Select this part when a 25ns speed grade is required alongside strict low-power standby constraints. Compare against the ATF22LV10CQZ series if surface-mount packaging or lower active supply current is preferred. Note that the CZ series is designated as not recommended for new designs; verify if the CQZ variant meets the physical footprint requirements.

Part Context

This component belongs to the ATF22LV10CZ/CQZ family of high-performance EEPLDs. The datasheet explicitly states that the ATF22LV10CZ series is not recommended for new designs and has been replaced by the ATF22LV10CQZ series. The 'PI' suffix denotes the Industrial temperature rating and PDIP package type within this lineage.

Replacement Considerations

The ATF22LV10CQZ series serves as the direct successor to the ATF22LV10CZ line. Specifically, the ATF22LV10CQZ-30PI offers a 30ns delay in the same package and temperature range, though it does not share the identical 25ns performance specification.
