ATF22LV10C-10XU

Overview

The ATF22LV10C-10XU is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells, 12 inputs, and 10 I/Os in a 24-lead TSSOP package. The device operates within a supply voltage range of 3.0V to 5.5V and supports industrial temperature ranges (-40°C to +85°C). Key electrical parameters include a maximum propagation delay of 10ns, a typical standby current of 10µA in power-down mode, and 200mA latchup immunity.

Feature Summary

• Advanced Electrically-Erasable Flash Memory Technology: Reprogrammable with 100 erase/write cycles and 20-year data retention.
• Low Power Consumption: Features user-controlled power-down pin option reducing standby current to 10µA typical; normal operating current as low as 10mA.
• High Performance: Maximum propagation delay of 10ns with CMOS and TTL compatible inputs and outputs.
• Robust Protection: Includes 200mA latchup immunity, 2000V ESD protection, and input pin-keeper circuits to maintain logic states.

Applications

• Glue logic for 3.3V systems
• DMA Control
• State Machine Control
• Graphics processing

Procurement Notes

Verify the ordering suffix 'XU' corresponds to the 24-lead TSSOP package and Industrial temperature range (-40°C to +85°C) as specified in the datasheet's ordering information table. Confirm RoHS compliance status if lead-free packaging is required for the specific revision.

Selection Notes

Select this component when a low-voltage EEPLD solution with zero standby power capability is needed. Ensure the design utilizes the PD pin for power-down control if minimizing system power is critical. Verify that the 10 macrocell capacity and 12-input limit meet the logic complexity requirements.

Part Context

This part belongs to the Atmel ATF22LV10C family of high-performance CMOS PLDs. It is designed to emulate standard 24-pin PAL devices while offering reprogrammability via electrically erasable Flash memory technology. The 'C' designation indicates compatibility with commercial/industrial standards, and the '10' denotes the 10ns speed grade.

Replacement Considerations

Direct replacements must match the 24-lead TSSOP package, 10ns max propagation delay, and 3.0V-5.5V operating range. Consider ATF22V10C variants for non-low-voltage applications or ATF22LV10CQZ for edge-sensing power-down features, ensuring pinout compatibility.
