ATF22V10C-7XC

Overview

The ATF22V10C-7XC is a high-performance CMOS electronically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It utilizes Flash memory technology to provide reprogrammability with 100% testing and 100 erase/write cycles. The device features 10 macrocells, 18 inputs, and 10 I/Os in a 24-pin TSSOP package. It operates at a maximum pin-to-pin propagation delay of 7.5 ns and supports a maximum frequency of 125 MHz. The unit functions on a 5V supply within the commercial temperature range of 0°C to +70°C.

Feature Summary

• High-speed performance with a maximum 7.5 ns pin-to-pin delay and 125 MHz operating frequency
• Electrically erasable Flash architecture allowing for 100 erase/write cycles and 20-year data retention
• Pin-controlled power-down mode reducing standby current to approximately 10 µA typical
• Internal input and I/O pin-keeper circuits to maintain logic states and reduce system power

Applications

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

Procurement Notes

Verify that the ordering suffix 'XU' corresponds to the specific TSSOP package variant required for the design. Confirm compliance with RoHS standards if lead-free components are mandated. Ensure the design file compiler mode matches the intended use of the power-down pin or standard logic input configuration.

Selection Notes

Select this component when a 7.5 ns speed grade is sufficient for the application timing requirements. The commercial temperature range (0°C to +70°C) limits suitability for harsh environments compared to industrial or military variants. Verify that the 24-lead TSSOP footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the ATF22V10C series of EEPLDs. It is backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices. The 'C' designation indicates the use of advanced Flash technology, distinguishing it from older EPROM-based PLDs. The device is available in multiple packages including DIP, SOIC, PLCC, and TSSOP.

Replacement Considerations

Direct replacements include other ATF22V10C speed grades such as ATF22V10C-10XU for relaxed timing requirements. For higher speed needs, the ATF22V10C-5JX offers a 5 ns delay but requires a PLCC package. Cross-family migration to ATF22V10V may be considered for lower power consumption.
