ATF22V10C-7JU

Overview

The ATF22V10C-7JU is an Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology, utilizing Atmel Flash memory technology. It features a maximum pin-to-pin propagation delay of 7.5 ns and operates within the industrial temperature range of -40°C to +85°C. The device is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. Key electrical specifications include a typical standby supply current of 85 µA and a maximum operating frequency of 125 MHz under external feedback conditions.

Feature Summary

• High-speed performance with a maximum propagation delay of 7.5 ns
• Pin-controlled power-down mode reducing supply current to less than 100 µA
• 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 that the component is sourced from authorized channels due to potential export restrictions associated with this product line. Confirm the specific ordering code matches the required speed grade and package type. Ensure compliance with RoHS standards if lead-free variants are necessary for the assembly process.

Selection Notes

Select the ATF22V10C-7JU when an industrial temperature range (-40°C to +85°C) is required alongside a 7.5 ns maximum delay. This part number specifically denotes the PLCC package configuration. Verify that the design utilizes the Power-Down feature via the PD pin if low-power operation is critical, as this requires specific compiler mode settings.

Part Context

This component belongs to the ATF22V10C series of high-performance CMOS EEPLDs. It serves as a drop-in replacement for legacy GAL devices while offering reprogrammability through Flash memory technology. The 'C' suffix indicates the use of advanced Flash technology compared to earlier OTP or EPROM versions.

Replacement Considerations

The ATF22V10C-7JU is backward-compatible with the Atmel ATF22V10B(Q) and AT22V10(L). When replacing older devices, ensure the programming software supports the specific JEDEC file format generated for the C-series architecture.
