ATF22V10B-15NM/883

Overview

The ATF22V10B-15NM/883 is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 22 inputs, and 10 I/O lines within a 24-lead Ceramic Dual Inline Package (CDIP). The device operates at a maximum propagation delay of 15 ns and supports a maximum frequency of 83.3 MHz with no feedback. It utilizes advanced Flash technology for reprogrammability and offers full military temperature range operation from -55°C to +125°C.

Feature Summary

• Advanced Flash Memory Technology: Provides 100% testing, 20-year data retention, and 100 erase/write cycles.
• High Reliability: Features 2,000V ESD protection and 200mA latchup immunity.
• Military Grade Performance: Supports full military temperature ranges (-55°C to +125°C) and complies with MIL-STD-883 Class B standards.
• Flexible Architecture: Includes internal input/I/O pull-up resistors, power-up reset circuitry, and synchronous preset capabilities.

Applications

• Complex logic replacement in military and aerospace systems
• State machine implementation requiring reliable initialization
• High-speed digital control interfaces

Procurement Notes

Verify the ordering suffix NM/883 corresponds to the 24-lead CDIP package and MIL-STD-883 compliance. Confirm that the specific speed grade (-15) meets the system timing requirements of 15 ns max propagation delay. Ensure export documentation is prepared if required for US-origin components.

Selection Notes

Select this part when a fully erasable PLD with military qualification is required. Compare against the -10GM variant for faster performance or the -25 variants for lower power consumption. Ensure the design accounts for the 65 mA typical standby current specified for the military temperature range.

Part Context

This component belongs to the ATF22V10B family of EEPLDs. It shares the same architectural core as commercial and industrial variants but is qualified for extended temperature ranges and harsh environments. The /883 suffix indicates compliance with Department of Defense procurement standards.

Replacement Considerations

Direct replacements include other ATF22V10B-15NM/883 units. Cross-referencing with older Atmel datasheets confirms pinout compatibility. Verify that any substitute maintains the 24-lead CDIP form factor and military temperature rating.

FAQ

What is the maximum operating frequency?

The maximum operating frequency is 83.3 MHz when configured with no feedback.

Does the device support power-up reset?

Yes, the registers are designed to reset to the low state during power-up, provided the VCC rise is monotonic.

How many macrocells does the ATF22V10B contain?

The device contains 10 macrocells.
