ATF22V10C-10SU

Overview

The ATF22V10C-10SU is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 18 registered inputs, and 10 I/O pins within a 24-lead Plastic Gull Wing Small Outline (SOIC) package. The device operates at a maximum propagation delay of 10 ns and supports a maximum frequency of 90 MHz with external feedback. It functions on a 5V supply voltage across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Utilizes advanced Flash memory technology for reprogrammability and 100% testing.
• Features pin-controlled standby power mode reducing current to approximately 10µA typical.
• Includes internal input and I/O pin-keeper circuits to maintain logic states without DC current draw.
• Supports synchronous preset, asynchronous reset, and power-up reset functionality.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'SU' corresponds to the 24-lead SOIC package configuration as defined in the official datasheet. Confirm that the required speed grade matches the 10 ns maximum propagation delay specification for industrial applications. Ensure programming tools support the JEDEC file format generated for the Power-down Mode compiler settings if this feature is utilized in the design.

Selection Notes

Select the ATF22V10C-10SU when a surface-mount solution is required for industrial environments (-40°C to +85°C). This part provides a balance of speed and pin count suitable for moderate complexity logic designs. Consider the ATF22V10C-7SX or ATF22V10C-5JX if faster switching speeds are necessary, or the ATF22V10C-15SU if lower power consumption is prioritized over speed.

Part Context

This component belongs to the ATF22V10C family of EEPLDs, which are backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices. The 'C' designation indicates the use of electrically erasable Flash technology, offering higher reliability and endurance compared to previous EPROM-based PLDs. The family supports various packages including DIP, SOIC, TSSOP, and PLCC.

Replacement Considerations

Direct replacements include other ATF22V10C variants with different speed grades or packages, such as ATF22V10C-10PU (PDIP) or ATF22V10C-10XU (TSSOP), provided the pinout compatibility is verified. For military specifications, the ATF22V10C-10GM/883 is available in a ceramic DIP package.
