ATF22V10BQ-15SI

Overview

The ATF22V10BQ-15SI is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) from the ATF22V10B family, manufactured by Microchip Technology. It features 10 macrocells and supports up to 10 I/O pins within a 24-pin PLCC package. The device operates at a maximum propagation delay of 15 ns and a maximum frequency of 55.5 MHz with external feedback. It requires a 5V power supply (±10% for military range) and draws a typical standby current of 55 mA. Designed for full military temperature ranges (-55°C to +125°C), it utilizes advanced Flash technology for reprogrammability.

Feature Summary

• High-speed EEPLD architecture with 10 macrocells and 10 I/Os
• Advanced Flash memory technology enabling 100 erase/write cycles and 20-year data retention
• CMOS and TTL compatible inputs/outputs with internal pull-up resistors
• Full military temperature operation (-55°C to +125°C) and 200mA latchup immunity

Applications

• Complex glue logic replacement in military systems
• State machine implementation requiring fast clock-to-output response
• Bus interface adapters with asynchronous reset capabilities
• Decoding and address translation circuits in harsh environments

Procurement Notes

Verify that the ordering suffix 'SI' corresponds to the specific PLCC-24 package variant documented in the official Microchip datasheet. Confirm compliance with DSCC drawings if military qualification is required. Check export control status as some variants may require additional documentation for international shipment. Ensure programming equipment supports the specific JEDEC file format for preload and security fuse settings.

Selection Notes

Select this part when a 15 ns propagation delay is sufficient for the target application speed. Compare against the -10GM variant if faster performance (10 ns delay) is needed, or the BQL series if lower power consumption is critical. Ensure the design accommodates the 55 mA typical standby current. Verify that the 24-pin PLCC footprint matches the PCB layout requirements.

Part Context

This component belongs to the ATF22V10B family of high-performance CMOS PLDs. It shares the same logical architecture and pinout compatibility with other members like the ATF22V10B-10GM and ATF22V10B-25NM, differing primarily in speed grade and package type. The family is designed to replace complex discrete logic gates while offering non-volatile reprogrammability via standard PLD programmers.

Replacement Considerations

Pin-compatible alternatives include the ATF22V10B-10GM/883 for faster switching speeds and the ATF22V10B-25NM/883 for slower, potentially lower-power applications. All share the same 24-pin military-grade ceramic packages. Verify that the substitute part meets the specific -55°C to +125°C operating range requirement.
