ATF22V10BQL-20PC

Overview

The ATF22V10BQL-20PC is a high-performance, electrically erasable programmable logic device (PLD) from the Atmel ATF22V10B family. It features 10 macrocells and supports up to 18 inputs and 10 bidirectional I/Os. The component utilizes advanced Flash technology for reprogrammability and offers a maximum propagation delay of 20 ns with a typical standby supply current of 5 mA. Designed for military applications, it operates within a temperature range of -55°C to +125°C and complies with MIL-STD-883 Class B standards.

Feature Summary

• Advanced Flash Technology: Electrically erasable/reprogrammable with 100% testing, 20-year data retention, and 100 erase/write cycles.
• Military Grade Reliability: Operates from -55°C to +125°C with 2,000V ESD protection and 200mA latchup immunity.
• Low Power Consumption: Typical standby current of 5 mA at commercial temperatures; CMOS and TTL compatible inputs/outputs.
• Standard Architecture: Industry-standard pinouts supporting DIP/SOIC and LCC/PLCC packages.

Applications

• Military-grade state machine initialization and control logic.
• High-reliability digital signal processing interfaces.
• Complex glue logic replacement in aerospace and defense systems.
• Secure logic designs utilizing built-in security fuse and electronic signature word capabilities.

Procurement Notes

Verify that the ordering suffix 'PC' corresponds to the specific package variant listed in the official Microchip or Atmel datasheet (Document 0250M). The provided documentation explicitly lists GM and NM suffixes for the 24D3 and 28L packages under the ATF22V10BQL-20 speed grade. Ensure the requested package matches the physical dimensions and pinout configurations defined for the specific military class compliance requirements.

Selection Notes

Select this part when a 20 ns propagation delay and low power consumption (5 mA typical) are required for military environments (-55°C to +125°C). The ATF22V10BQL series provides lower power than standard B-series parts while maintaining full military temperature ranges. Ensure the design accommodates the 10 macrocell capacity and 18 input/10 I/O pin configuration.

Part Context

This component belongs to the Atmel ATF22V10B family of high-performance EEPLDs. The 'QL' suffix indicates a low-power variant optimized for military temperature ranges. The device replaces older GAL-based logic with non-volatile Flash memory, allowing field reprogramming without UV erasure, making it suitable for complex digital logic applications requiring high reliability.

Replacement Considerations

Direct replacements include ATF22V10BQL-20GM/883 and ATF22V10BQL-20NM/883, which share identical electrical specifications and timing parameters. Verify package compatibility if substituting between Ceramic Dual Inline (GM) and Leadless Chip Carrier (NM) formats.
