ATF22V10CQ-15JI

Overview

The ATF22V10CQ-15JI is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 22 inputs, and 10 I/O lines within a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. The device operates at a maximum propagation delay of 15 ns and supports a maximum frequency of 55.5 MHz with external feedback. It functions on a 5V supply voltage across an industrial temperature range of -40°C to +85°C.

Feature Summary

• High-speed performance with 15 ns maximum pin-to-pin delay
• Pin-controlled power-down mode reducing standby current to 10 µA typical
• Advanced Flash technology allowing 100 erase/write cycles and 20-year data retention
• Backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) architectures

Applications

• Glue logic for 5.0V systems
• DMA control circuits
• State machine control
• Graphics processing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compliance with export regulations if applicable. Confirm RoHS status and lead-free requirements prior to procurement.

Selection Notes

Select this component for applications requiring industrial temperature stability (-40°C to +85°C) and moderate speed (15 ns). Consider the PLCC package for through-hole mounting. Verify that the 10 macrocell capacity meets logic density requirements compared to higher-density alternatives.

Part Context

This part belongs to the ATF22V10C series of EEPLDs. It utilizes CMOS Flash memory technology, offering reprogrammability without UV erasure. The 'CQ' designation indicates a commercial-grade variant adapted for industrial use or specific power-down capabilities, while '15' denotes the 15 ns speed grade.

Replacement Considerations

The ATF22V10CQ-15JI is backward-compatible with the Atmel ATF22V10B(Q) and AT22V10(L) series. Direct replacements must match the 28-lead PLCC package and 15 ns speed grade.
