ATF22LV10CQZ-30PC

Overview

The ATF22LV10CQZ-30PC is an electrically erasable programmable logic device (PLD) manufactured by Microchip Technology, formerly Atmel. It features a high-performance CMOS architecture with 12 inputs and 10 I/O macrocells. The device operates within a supply voltage range of 3.0V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. Key electrical specifications include a maximum propagation delay of 30ns for non-registered outputs and a typical standby current of 5µA enabled by Input Transition Detection circuitry. The package is a 24-pin Plastic Dual Inline Package (PDIP).

Feature Summary

• Low-voltage operation with 'Zero' standby power mode (25µA max) via Input Transition Detection.
• CMOS and TTL-compatible inputs and outputs with 5V tolerant I/O pins.
• Reprogrammable Flash memory technology supporting 10,000 erase/write cycles and 20-year data retention.
• Variable product term architecture allowing 8 to 16 product terms per output.

Applications

• Battery-powered systems requiring low standby power consumption.
• Logic replacement for legacy 24-pin PAL devices.
• Industrial control interfaces utilizing 5V tolerant I/O capabilities.

Procurement Notes

Verify the ordering suffix 'PC' corresponds to the 24-pin PDIP package and Industrial temperature range (-40°C to +85°C). Confirm that the component meets RoHS compliance requirements if specified in the procurement documentation. Ensure programming equipment supports the specific EEFlash architecture of the ATF22LV10CQZ series.

Selection Notes

Select this part when a low-power, reprogrammable logic solution is needed for industrial environments. The CQZ variant offers lower active current compared to the older CZ series. Ensure the design accommodates the 3.0V minimum supply voltage and utilizes the internal pin keepers to maintain logic states during idle periods.

Part Context

The ATF22LV10CQZ-30PC belongs to the ATF22LV10CQZ family, which serves as the low-voltage successor to the obsolete ATF22LV10CZ series. The 'CQZ' designation indicates the inclusion of Input Transition Detection for zero-power standby modes. This specific model replaces the standard commercial-grade parts with an industrial temperature rating.

Replacement Considerations

The ATF22LV10CZ series is obsolete and replaced by the ATF22LV10CQZ series. For direct functional replacement in existing designs, verify compatibility with the lower active current and ensure the programming toolchain supports the CQZ architecture.
