ATF22V10C-7JI

Overview

The ATF22V10C-7JI is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 18 inputs, and 10 I/Os within a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. The device operates at a maximum pin-to-pin propagation delay of 7.5 ns with a typical standby power consumption of 10 µA. It utilizes advanced Flash technology for reprogrammability and supports full industrial temperature ranges (-40°C to +85°C).

Feature Summary

• High-speed performance with a maximum 7.5 ns pin-to-pin delay.
• 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 the specific ordering suffix 'JI' against official documentation to confirm the PLCC package and industrial temperature range specifications. Ensure compatibility with existing design files and programming hardware before procurement.

Selection Notes

Select this component for applications requiring fast switching speeds and low standby power in an industrial environment. Consider the 28-lead PLCC package constraints and ensure the design file enables the power-down feature if required.

Part Context

This part belongs to the ATF22V10C series of EEPLDs. It shares architectural similarities with the ATF22V10B but offers enhanced speed and lower power dissipation options through its CMOS process and Flash memory technology.

Replacement Considerations

The ATF22V10C-7JI is backward-compatible with the Atmel ATF22V10B(Q) and AT22V10(L). Verify pinout and electrical characteristics when substituting these legacy parts.

FAQ

What is the function of the PD pin?

The PD pin controls the power-down mode. When high, it reduces supply current significantly while latching all output data and internal logic states.

How does the device handle floating inputs?

Internal pin-keeper circuits hold the previous value of each pin, preventing them from floating to indeterminate levels and reducing system power.

What is the purpose of the security fuse?

The security fuse prevents unauthorized copying of the device's fuse patterns. Once programmed, fuse verify and preload are inhibited, though the 64-bit User Signature remains accessible.
