ATF22V10C-10JC

Overview

The ATF22V10C-10JC is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 22 inputs, and 10 I/O lines within a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. The device operates at a maximum propagation delay of 10 ns and supports a maximum frequency of 90 MHz with external feedback. It utilizes advanced Flash technology for reprogrammability and offers low standby power consumption of 10 µA typical via pin-controlled power-down mode.

Feature Summary

• High-speed performance with 10 ns max pin-to-pin delay and 90 MHz max frequency
• Advanced Flash memory technology allowing 100 erase/write cycles and 20-year data retention
• Pin-controlled power-down mode reducing supply current to 10 µA typical
• Internal input and I/O pin-keeper circuits to maintain logic states

Applications

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

Procurement Notes

Verify the specific ordering suffix 'JC' against official documentation, as standard listings typically use 'JU' for Industrial PLCC packages. Confirm RoHS compliance status and export restrictions if applicable. Ensure programming tools support the JEDEC file format generated for the ATF22V10C series compiler modes.

Selection Notes

Select this component for designs requiring 10 macrocells and 22 inputs in a surface-mount PLCC package. The 10 ns speed grade is suitable for industrial applications (-40°C to +85°C). Consider the -5JX variant for commercial temperature ranges or DIP/SOIC packages if through-hole mounting is required.

Part Context

This part belongs to the ATF22V10C family of EEPLDs, which are backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices. The family includes various speed grades (-5, -7, -10, -15) and package options including DIP, SOIC, TSSOP, PLCC, and LCC.

Replacement Considerations

ATF22V10C-10JU: Same electrical specifications and package (PLCC), but specified for Industrial temperature range (-40°C to +85°C) rather than Military.

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 during this period.

What is the purpose of the pin-keeper circuits?

The internal pin-keeper circuits hold each pin at its previous logic state when not driven externally, preventing floating inputs and reducing system power without requiring DC current.

Can the ATF22V10C be used in military applications?

Yes, specific variants like ATF22V10C-10GM/883 are available in ceramic packages and meet military temperature ranges (-55°C to +125°C).
