ATF22LV10CQZ-30JU

Overview

The ATF22LV10CQZ-30JU is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features 12 inputs and 10 I/O macrocells with a maximum propagation delay of 30 ns and a maximum operating frequency of 33.3 MHz. 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. It utilizes advanced low-voltage CMOS technology, offering a typical standby current of 5µA through Input Transition Detection circuitry.

Feature Summary

• Low-power operation with 'zero' standby power (25µA maximum) via Input Transition Detection
• CMOS and TTL-compatible inputs and outputs with 5V tolerant pins
• High-reliability CMOS process ensuring 20-year data retention and 10,000 erase/write cycles
• Variable product term architecture providing 8 to 16 product terms per output

Applications

• Battery-powered systems requiring low standby current
• Logic replacement for legacy PAL devices
• Industrial control applications within specified temperature ranges

Procurement Notes

Verify the package type corresponds to the 'J' suffix, indicating a 28-lead Plastic J-leaded Chip Carrier (PLCC). Confirm that the 'U' suffix denotes compliance with RoHS standards and lead-free/halide-free material specifications as defined in the green package options section of the datasheet.

Selection Notes

Select this component when a 30 ns speed grade is required for industrial environments (-40°C to +85°C). Ensure the design accommodates the PLCC footprint if using the JU variant. Consider the CQZ series over the CZ series for lower high-frequency supply current consumption.

Part Context

This part belongs to the ATF22LV10CQZ family, which serves as the low-voltage equivalent to the Atmel ATF22V10CZ. The ATF22LV10CZ is noted as obsolete and replaced by the CQZ variants. The specific JU designation identifies the industrial temperature range and PLCC packaging configuration.

Replacement Considerations

The ATF22LV10CZ is obsolete and replaced by the ATF22LV10CQZ series. For direct functional substitution within the same family, consider the ATF22LV10CQZ-30JI, which shares identical electrical characteristics but utilizes the PLCC package.
