ATF22V10BQ-15PC

Overview

The ATF22V10BQ-15PC is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) from the ATF22V10B family, manufactured by Microchip Technology. It features 10 macrocells and 10 I/O pins within a 24-pin DIP package. The device utilizes advanced Flash technology for reprogrammability and offers a maximum propagation delay of 15 ns. It operates at a standard 5V supply voltage with a typical standby current of 35 mA and a maximum of 55 mA. The component supports full military temperature ranges (-55°C to +125°C) and includes internal pull-up resistors, power-up reset, and synchronous preset capabilities.

Feature Summary

• Advanced Flash Memory Technology: Provides 100% testing, 20-year data retention, 100 erase/write cycles, and 2,000V ESD protection.
• High-Speed Performance: Achieves a maximum operating frequency of 55.5 MHz with a 15 ns propagation delay.
• Low Power Consumption: Features a typical standby current of 35 mA at 5V, suitable for power-limited applications.
• Military Grade Reliability: Supports full military temperature range (-55°C to +125°C) and 200mA latchup immunity.

Applications

• Complex glue logic replacement in digital systems
• State machine implementation requiring reliable initialization
• Decoding and address translation circuits
• Timing control and synchronization logic

Procurement Notes

Verify that the ordering suffix 'PC' corresponds to the specific 24-lead Ceramic Dual Inline Package (CDIP) variant documented in the official datasheet. Confirm compliance with export regulations if applicable, as some military-grade variants may require additional documentation for shipment from the United States. Ensure the supplier provides valid traceability for the military temperature grade.

Selection Notes

Select this part when a 15 ns speed grade is required alongside low standby power consumption (35 mA typ). The BQ suffix indicates a specific power profile distinct from the standard B series. Ensure the design accommodates the 24-pin CDIP footprint and verifies compatibility with the 5V ±10% supply tolerance required for military/industrial operation.

Part Context

This component belongs to the ATF22V10B family of EEPLDs, which are designed as drop-in replacements for complex PAL devices. The 'BQ' designation specifically denotes a lower power variant compared to the standard B-15 model. The device architecture includes 11 dedicated inputs and 10 I/O lines, supporting both combinatorial and registered outputs.

Replacement Considerations

Direct pin-compatible substitutes include other ATF22V10B variants such as ATF22V10B-15GM or ATF22V10B-15NM, provided the power consumption and package type (CDIP vs. DIP/Ceramic) requirements are met. Verify that any replacement maintains the 15 ns delay specification and military temperature rating.
