ATF22V10CQ-15SI

Overview

The ATF22V10CQ-15SI is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology, originally designed by Atmel. It features 10 macrocells and supports up to 18 inputs and 10 bidirectional I/Os within a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. The device operates at a maximum propagation delay of 15 ns and a maximum frequency of 55.5 MHz under external feedback conditions. It functions on a 5V supply with an industrial temperature range of -40°C to +85°C.

Feature Summary

• High-speed performance with 15 ns maximum pin-to-pin delay
• Pin-controlled power-down mode reducing standby current to 10 µA typical
• Internal input and I/O pin-keeper circuits to maintain logic states
• Backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) architectures

Applications

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

Procurement Notes

Verify the specific suffix 'SI' against official ordering tables, as standard documentation lists 'JU' for PLCC packages in this speed grade. Confirm RoHS compliance status if required, noting that green package options are available separately. Ensure programming tools support the 5893 fuse bit configuration for power-down mode activation.

Selection Notes

Select this component when a 15 ns delay is sufficient for the target circuit timing requirements. The PLCC package is suitable for through-hole mounting or socketed applications. Consider the CQ variant specifically for its lower active supply current compared to standard C-series devices.

Part Context

This part belongs to the ATF22V10C family of EEPLDs, which utilize advanced Flash memory technology for reprogrammability. The 'CQ' designation indicates a low-power version optimized for reduced supply current consumption during operation while maintaining the same logical architecture as the standard ATF22V10C.

Replacement Considerations

ATF22V10C-15JU: Same speed and package type but without the low-power CQ specification.
