ATF22LV10CZ-25JI

Overview

The ATF22LV10CZ-25JI is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells and 12 inputs, delivering a maximum propagation delay of 25 ns. The device operates within a supply voltage range of 3.0V to 5.5V and supports industrial temperature conditions from -40°C to +85°C. Packaged in a 28-lead Plastic J-leaded Chip Carrier (PLCC), it utilizes Atmel's Flash memory technology for reprogrammability and includes Input Transition Detection circuitry to achieve low standby power consumption.

Feature Summary

• Low-voltage operation with a 3.0V to 5.5V supply range
• Input Transition Detection (ITD) circuitry for zero-power standby mode
• Reprogrammable via standard PLD programmers using EEPROM technology
• CMOS and TTL-compatible I/Os with 5V tolerant inputs

Applications

• Battery-powered systems requiring low standby current
• Logic replacement for legacy PAL devices
• Industrial control interfaces
• General-purpose digital logic implementation

Procurement Notes

Verify the package type corresponds to the 28J designation (PLCC). Confirm that the specific ordering suffix matches the required speed grade (-25) and industrial temperature range (-JI). Ensure programming equipment supports the Atmel/Flash architecture specified in the datasheet.

Selection Notes

Select this component when a 25 ns speed grade is sufficient for the application timing requirements. The Industrial temperature rating (-40°C to +85°C) makes it suitable for harsh environments compared to commercial variants. Consider the CQZ series if lower active current consumption is prioritized over the CZ speed performance.

Part Context

This part belongs to the ATF22LV10C family of EEPLDs. The datasheet notes that the ATF22LV10CZ series is becoming obsolete and is replaced by the ATF22LV10CQZ series. The 'C' indicates Commercial speed characteristics de-rated for Industrial use, while 'Z' denotes the low-power variant.

Replacement Considerations

The ATF22LV10CQZ-30JI is the recommended replacement for new designs. While the CQZ variant offers lower power consumption, it has a slower maximum propagation delay of 30 ns compared to the 25 ns of the CZ-25 variant.
