ATF22LV10CZ-25JC

Overview

The ATF22LV10CZ-25JC is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology, originally designed by Atmel. It features a variable product term architecture with 10 macrocells and 12 inputs. The device operates within a supply voltage range of 3.0V to 5.5V and delivers a maximum propagation delay of 25ns. It utilizes Input Transition Detection (ITD) circuitry to achieve standby currents as low as 25µA. The component is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package and supports commercial temperature operation from 0°C to +70°C.

Feature Summary

• Low-voltage EEPLD technology with 3.0V to 5.5V operating range
• Input Transition Detection (ITD) for zero-power standby mode (max 25µA)
• CMOS and TTL compatible I/Os with 5V tolerant inputs
• Variable product term architecture with 10 macrocells

Applications

• Battery-powered systems requiring low standby power
• Logic replacement for legacy PAL devices
• General-purpose digital logic control circuits

Procurement Notes

Verify the manufacturer origin, as the datasheet identifies Atmel Corporation. Confirm that the specific ordering suffix corresponds to the PLCC package type and commercial temperature range. Ensure programming hardware compatibility with standard PLD programmers for the electrically erasable Flash memory structure.

Selection Notes

Select this part for applications needing 10 macrocells with 25ns speed at 5V or lower voltages. Compare against the ATF22LV10CQZ series for industrial temperature ranges (-40°C to +85°C) and lower active current consumption. Verify package availability, as the PLCC option may be subject to obsolescence notices in favor of green package alternatives.

Part Context

This component belongs to the ATF22LV10C family of high-performance CMOS PLDs. It serves as a low-voltage equivalent to the Atmel ATF22V10CZ. The datasheet notes that the ATF22LV10CZ series is becoming obsolete and is replaced by the ATF22LV10CQZ parts in green package offerings.

Replacement Considerations

The ATF22LV10CZ series is officially noted as obsolete and replaced by the ATF22LV10CQZ series. For industrial temperature requirements, consider the ATF22LV10CQZ-30JI which offers similar functionality with updated packaging.
