ATF22LV10CZ-25PC

Overview

The ATF22LV10CZ-25PC is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features a 24-pin PDIP package and operates within a 3.0V to 5.5V supply range. The device provides a maximum propagation delay of 25ns and supports up to 10 macrocells with 12 inputs and 10 I/Os. It utilizes advanced low-voltage CMOS technology, offering a typical standby current of 5µA through input transition detection circuitry. The architecture includes variable product terms for complex logic functions.

Feature Summary

• Low-power operation with 25µA maximum standby current
• 25ns maximum propagation delay at 3.0V to 5.5V
• 10 macrocells with 12 inputs and 10 bidirectional I/Os
• CMOS and TTL compatible inputs with 5V tolerance

Applications

• Battery-powered systems requiring low standby power
• General-purpose digital logic replacement
• State machine implementations with registered outputs

Procurement Notes

Verify the specific ordering suffix PC corresponds to the 24-pin Plastic Dual Inline Package (PDIP). Confirm that the -25 speed grade meets the system timing requirements of 25ns maximum propagation delay. Check for RoHS compliance status as standard packages may differ from green package options.

Selection Notes

Select this component when a 24-pin DIP footprint is required for prototyping or legacy board designs. Ensure the design accommodates the 3.0V minimum operating voltage if using lower supply rails. Consider the CQZ variant if surface mount packaging or improved power efficiency is preferred over the obsolete CZ series.

Part Context

This part belongs to the ATF22LV10CZ family of high-performance EEPLDs. The datasheet notes that the ATF22LV10CZ series is becoming obsolete and is replaced by the ATF22LV10CQZ series. The 'PC' suffix specifically denotes the commercial temperature range (0°C to 70°C) and PDIP package type.

Replacement Considerations

The ATF22LV10CQZ-30PC is the recommended replacement for new designs. While it offers similar functionality, it has a 30ns propagation delay compared to the 25ns of the CZ series. Verify that the increased delay does not impact critical path timing in the application.
