ATF22LV10CQZ-30SU

Overview

The ATF22LV10CQZ-30SU is a high-performance, electrically erasable programmable logic device (PLD) manufactured by Microchip Technology. It features 10 macrocells and supports up to 10 I/Os within a 24-lead SOIC package. The device operates on a supply voltage range of 3.0V to 5.5V and achieves a maximum operating frequency of 33.3 MHz with a typical propagation delay of 30 ns. It incorporates Input Transition Detection (ITD) for zero standby power consumption, drawing a maximum of 25µA in standby mode. The component is rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• Low-voltage operation with 3.0V to 5.5V supply range and CMOS/TTL compatibility
• Zero standby power capability via Input Transition Detection (ITD) circuitry
• High-reliability EEPROM technology with 10,000 erase/write cycles and 20-year data retention
• Variable product term architecture allowing 8 to 16 terms per output

Applications

• Battery-powered systems requiring low power consumption
• Complex logic replacement for legacy PAL devices
• Industrial control interfaces and signal buffering
• State machine implementation with synchronous preset and asynchronous reset capabilities

Procurement Notes

Verify the package type matches the 'S' suffix for SOIC-24. Confirm the temperature grade corresponds to the 'U' suffix for Industrial (-40°C to +85°C). Ensure the design utilizes the correct programming hardware compatible with Atmel/Microchip PLDs. Check for RoHS compliance status if required by specific environmental regulations.

Selection Notes

Select this part when replacing obsolete ATF22LV10CZ devices with improved power efficiency. Choose the CQZ variant over CZ for lower active current and zero-power standby modes. Ensure the application requires 10 macrocells and fits within the 30ns speed constraint. Verify that the 24-pin SOIC footprint aligns with the PCB layout requirements.

Part Context

This component belongs to the ATF22LV10CQZ family, which serves as the low-voltage successor to the standard ATF22LV10CZ series. The 'CQZ' designation indicates enhanced performance characteristics, specifically reduced power consumption compared to the original 'CZ' parts. The 'SU' suffix identifies the specific industrial temperature range and surface-mount SOIC packaging configuration.

Replacement Considerations

The ATF22LV10CZ is obsolete and replaced by the ATF22LV10CQZ. When substituting older CZ variants, account for differences in active supply current (ICC) and verify pinout compatibility. No functional changes are introduced by the ordering suffixes regarding core logic operations.
