ATF22V10C-10SI

Overview

The ATF22V10C-10SI is an Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology, originally designed by Atmel. It features a high-performance CMOS architecture with 10 macrocells and 10 I/O pins in a 24-pin SOIC package. The device offers a maximum pin-to-pin propagation delay of 10 ns and operates at a maximum frequency of 90 MHz with external feedback. It functions on a 5V supply within ±10% tolerance for industrial applications (-40°C to +85°C). Key electrical characteristics include a typical standby current of 85 µA and a clocked power supply current of up to 160 mA.

Feature Summary

• High-speed performance with 10 ns maximum propagation delay and 90 MHz max frequency.
• Electrically erasable Flash memory technology allowing 100 erase/write cycles and 20-year data retention.
• Pin-controlled power-down mode reducing supply current to less than 100 µA while latching output states.
• Internal input and I/O pin-keeper circuits maintain logic levels without DC current draw.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'SI' against official Microchip/Atmel documentation, as standard listings typically use 'SU' for SOIC packages. Confirm RoHS compliance status and export restrictions if applicable. Ensure programming tools support the JEDEC file format generated for the 22V10C architecture with power-down mode options if required.

Selection Notes

Select this component for designs requiring 10 macrocells with 10 ns timing constraints in an industrial temperature range. Compare against ATF22V10C-7PX for faster commercial-grade performance or ATF22V10B variants for backward compatibility. Consider the SOIC package dimensions and moisture sensitivity level during PCB layout and assembly planning.

Part Context

This part belongs to the ATF22V10C series of high-performance EEPLDs. It is backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices. The series utilizes advanced Flash technology for reprogrammability and includes features like asynchronous reset and synchronous preset capabilities for flexible logic design.

Replacement Considerations

ATF22V10C-10SU is the standard commercial equivalent for the SOIC package. ATF22V10C-10JU serves as the PLCC alternative. For military specifications, consider ATF22V10C-10GM/883. Verify package pinout compatibility before substitution.

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 100 µA. All output data and internal logic states are latched and held, and inputs except the PD pin are blocked.

What is the purpose of the pin-keeper circuits?

The internal pin-keeper circuits hold previous logic values on un-driven pins, preventing them from floating to indeterminate levels. This reduces system power by eliminating the need for external pull-up resistors.

Can the ATF22V10C-10SI be used in place of an ATF22V10B?

Yes, the ATF22V10C series is backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices, allowing for direct replacement in many existing designs.
