ATF22V10BQL-20JC

Overview

The ATF22V10BQL-20JC is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology, utilizing Atmel Flash memory technology. It features 10 macrocells and supports up to 10 I/Os within a 24-pin Ceramic Dual Inline Package (CDIP). The device operates at a maximum propagation delay of 20 ns with a clock-to-output delay of 12 ns. It functions over the full military temperature range of -55°C to +125°C with a 5V ±10% power supply. Standby current is typically 10 mA for commercial and 15 mA for industrial/military grades.

Feature Summary

• Advanced Flash Memory: Reprogrammable with 100 erase/write cycles and 20-year data retention.
• Military Grade Reliability: Operates from -55°C to +125°C with 2,000V ESD protection and 200mA latchup immunity.
• CMOS/TTL Compatibility: Inputs and outputs are compatible with both CMOS and TTL logic levels.
• Internal Pull-ups: Built-in input and I/O pull-up resistors ensure known states when undriven.

Applications

• High-reliability aerospace and defense systems requiring full military temperature operation.
• Industrial control applications needing reprogrammable logic with low standby power.
• State machine implementations utilizing the power-up reset feature for initialization.

Procurement Notes

Verify that the ordering suffix matches the required package and speed grade. The 'QL' suffix indicates the specific speed bin (-20ns), while 'JC' denotes the ceramic dual inline package. Confirm compliance with DSCC drawings if purchasing under the 5962-89841 designation. Ensure export documentation is prepared as this product may require additional files for export from the United States.

Selection Notes

Select the ATF22V10BQL-20JC when a 20 ns propagation delay is sufficient for the design timing requirements. This part is suitable for designs requiring the robustness of a ceramic package and operation across the entire military temperature spectrum. Compare against the B-15 or B-25 variants if different speed or power trade-offs are needed.

Part Context

This component belongs to the ATF22V10B family of high-speed EEPLDs. It shares the same architecture and pinout as other members in the series but is distinguished by its specific speed grade (-20 ns) and military-grade environmental ratings. The device replaces older GAL technologies with non-volatile Flash memory capabilities.

Replacement Considerations

Direct replacements include ATF22V10BQL-20GM/883 and ATF22V10BQL-20NM/883, which share identical electrical specifications and military compliance. These parts offer alternative packaging options such as LCC or standard CDIP configurations while maintaining the -20 ns performance level.
