ATF22V10C-15PC

Overview

The ATF22V10C-15PC is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 18 inputs, and 10 I/O pins in a 24-pin Plastic Dual Inline Package (PDIP). The device operates at a maximum propagation delay of 15 ns with a typical standby power consumption of 10 µA. It utilizes advanced Flash technology for reprogrammability and offers 20-year data retention. The component supports full military, industrial, and commercial temperature ranges.

Feature Summary

• High-speed performance with a maximum pin-to-pin delay of 15 ns
• Pin-controlled standby power mode reducing supply current to less than 100 µA
• Advanced Flash memory technology providing 100% test coverage and 100 erase/write cycles
• Backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) architectures

Applications

• Glue logic for 5.0V systems
• DMA control circuits
• State machine control
• Graphics processing

Procurement Notes

Verify the package type matches the required footprint, as the standard datasheet lists PDIP (24P3), SOIC (24S), PLCC (28J), and LCC (28L) options. Confirm the suffix indicates the correct speed grade (-15) and temperature range. Check for export restrictions if sourcing from specific regions. Ensure programming tools support the JEDEC file format generated for this specific architecture.

Selection Notes

Select the ATF22V10C-15PC when a 15 ns delay is acceptable and low-power standby operation is required. Compare against the -10JU or -10PU variants if faster switching speeds are needed. Consider the -7PX or -5JX models for higher frequency applications up to 166 MHz. Verify that the 24-pin DIP package fits the board layout constraints compared to surface-mount alternatives like TSSOP or SOIC.

Part Context

This component belongs to the ATF22V10C family of EEPLDs, which succeeded the older ATF22V10B series. The 'C' designation indicates the use of Atmel's advanced Flash technology, allowing for electrical erasure and reprogramming without UV light. The part is widely used in legacy designs requiring complex logic functions in a small form factor.

Replacement Considerations

Direct replacements include other ATF22V10C variants with different speed grades or packages, such as ATF22V10C-10JU or ATF22V10C-7PX. Cross-family replacements like the ATF22V10B-15JU may require verification of timing parameters and power characteristics.
