ATF22V10C-7SC

Overview

The ATF22V10C-7SC is a high-performance CMOS electronically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells and 10 I/O pins in a 24-pin SOIC package. The device provides a maximum pin-to-pin propagation delay of 7.5 ns, supporting a maximum operating frequency of 125 MHz. It operates on a 5V supply with a typical standby power consumption of 10µA. The component utilizes advanced Flash technology for reprogrammability and includes pin-controlled power-down capabilities.

Feature Summary

• High-speed performance with 7.5 ns maximum propagation delay
• Pin-controlled standby power mode reducing current to 10µA typical
• Internal input and I/O pin-keeper circuits to maintain logic states
• Backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L)

Applications

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

Procurement Notes

Verify the specific package suffix 'SC' against official ordering tables, as standard documentation lists 'SX' for the 24-lead Plastic Gull Wing Small Outline (SOIC) package. Confirm RoHS compliance status and temperature range requirements prior to procurement. Ensure programming tools support the JEDEC file format generated for this device architecture.

Selection Notes

Select this part for applications requiring fast combinatorial logic with low standby power. The 7.5 ns delay suits moderate-speed digital designs. Consider the -7 speed grade if system timing allows for slower commercial-grade devices to reduce costs. Verify that the 24-pin SOIC footprint matches the PCB layout constraints.

Part Context

This component belongs to the ATF22V10C family of EEPLDs. It shares architectural similarities with the ATF22V10B series but offers electrically erasable Flash memory instead of EEPROM. The device is designed to replace older GAL and PAL logic components in existing designs while providing non-volatile reprogrammability.

Replacement Considerations

ATF22V10C-7PX: PDIP-24 package variant with identical electrical specifications.

FAQ

How does the power-down mode function?

When the PD pin is driven high, the device enters power-down mode, reducing supply current to less than 100µA. Output data and internal logic states are latched and held during this period.

What is the purpose of the pin-keeper circuits?

The pin-keeper circuits hold inputs and I/O pins at their previous logic state when not actively driven, preventing floating pins and reducing system power consumption.

Is the device compatible with standard PLD programmers?

Yes, programming and erasing are performed using standard PLD programmers that support the JEDEC file format generated by compatible design software.
