ATF22V10B-15JC

Overview

The ATF22V10B-15JC is a high-performance CMOS electrically erasable programmable logic device (PLD) utilizing Flash memory technology. It features 10 macrocells, 11 dedicated inputs, and 10 I/O lines within a 24-pin DIP package. The -15 speed grade specifies a maximum propagation delay of 15 ns and a maximum operating frequency of 55.5 MHz under external feedback conditions. The device operates on a 5V supply with a typical standby current of 115 mA in military temperature ranges (-55°C to +125°C).

Feature Summary

• Electrically Erasable Flash Memory: Supports 100 erase/write cycles and retains data for 20 years.
• High-Speed Logic: Maximum propagation delay of 15 ns with 10 macrocells and 22 total I/O lines.
• Military Grade Reliability: Operates from -55°C to +125°C with 2,000V ESD protection and 200mA latchup immunity.
• Power-Up Reset: Registers reset to low state upon power-up to ensure deterministic state machine initialization.

Applications

• Complex glue logic replacement in industrial control systems.
• State machine implementation requiring full military temperature range operation.
• Digital signal processing interfaces requiring fast combinatorial output response.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and environmental rating. The datasheet lists military-grade ceramic packages such as CDIP-24 (GM/883) and LCC-28 (NM/883). Ensure the requested suffix matches the required pinout and thermal specifications for the target application environment.

Selection Notes

Select the ATF22V10B-15JC when a 15 ns propagation delay is sufficient for the system clock requirements. Compare the 55.5 MHz maximum frequency against the design constraints. Consider the BQ or BQL variants if lower power consumption is critical, as standard B-series devices draw up to 115 mA in standby mode at military temperatures.

Part Context

This component belongs to the ATF22V10B family of high-performance EEPLDs. The series offers various speed grades (-7, -10, -15, -25) and packaging options including DIP, SOIC, PLCC, and LCC. The -15 variant provides a balance between switching speed and power dissipation suitable for general-purpose digital logic applications.

Replacement Considerations

Direct replacements include other ATF22V10B speed grades such as ATF22V10B-10GM/883 for faster performance or ATF22V10B-25GM/883 for lower power. Verify that the substitute part maintains the same 24-pin footprint and military temperature rating if those constraints are mandatory.
