ATF22V10B-15PC

Overview

The ATF22V10B-15PC is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) from Microchip Technology, utilizing advanced Flash memory technology. It features 10 macrocells and 10 I/O lines within a 24-pin Dual In-line Package (PDIP). The device operates at a maximum propagation delay of 15 ns with a typical power supply current of 65 mA in standby mode. Designed for robust industrial applications, it supports a wide operating temperature range from -55°C to +125°C and includes internal pull-up resistors for inputs and I/Os.

Feature Summary

• Advanced Flash Memory Technology: Offers reprogrammability with 100% testing, 20-year data retention, and 100 erase/write cycles.
• High-Speed Performance: Achieves a maximum frequency of 83.3 MHz with a 15 ns propagation delay.
• Robust Reliability: Features 2,000V ESD protection and 200mA latchup immunity.
• Power Management: Includes low-power options and internal input/I/O pull-up resistors.

Applications

• Complex logic replacement in digital systems
• State machine implementation
• Address decoding and control logic

Procurement Notes

Verify the package type matches the specific application requirements, as the ATF22V10B series is available in multiple packages including CDIP and PDIP. Confirm that the military temperature grade (-55°C to +125°C) aligns with the environmental conditions of the target system. Ensure compatibility with existing PLD programming hardware and software tools for reliable configuration.

Selection Notes

Select the ATF22V10B-15PC when a 15 ns speed grade is required alongside full military temperature coverage. Compare against other speed grades like -10 or -25 based on timing constraints. Consider the PDIP-24 package for through-hole mounting needs. Verify that the 10 macrocell capacity suffices for the intended logic complexity before finalizing the part number.

Part Context

This component belongs to the ATF22V10B family of EEPLDs, which are designed as drop-in replacements for standard PAL devices. The 'B' suffix indicates the specific speed grade and feature set optimized for high-reliability applications. The device integrates Flash memory to allow non-volatile storage of logic configurations without UV erasure.

Replacement Considerations

Direct pin-compatible substitutes include other ATF22V10B variants with different speed grades (e.g., ATF22V10B-10PC or ATF22V10B-25PC), provided timing requirements are met. Cross-family replacements may require schematic review due to potential differences in pinouts or electrical characteristics.
