ATF22V10CQ-15SC

Overview

The ATF22V10CQ-15SC is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells and 22 inputs/outputs in a 24-pin SOIC package. The maximum pin-to-pin propagation delay is 15 ns, supporting a maximum operating frequency of 55.5 MHz. It operates on a 5 V power supply within the industrial temperature range of -40°C to +85°C. Key electrical characteristics include a typical standby current of 35 µA and a maximum active supply current of 70 mA.

Feature Summary

• High-speed performance with a maximum 15 ns propagation delay
• Pin-controlled power-down mode reducing supply current to less than 100 µA
• Internal input and I/O pin-keeper circuits to maintain valid logic states
• Backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) architectures

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status if lead-free materials are mandatory for the assembly process. Ensure programming equipment supports the JEDEC file format generated by the designated compiler mode selection.

Selection Notes

Select this component when a 15 ns speed grade is sufficient for the target application timing requirements. The CQ variant offers lower active power consumption compared to standard C devices. Verify that the design utilizes the Power-Down feature via the PD pin configuration if low-power operation is required.

Part Context

This device belongs to the ATF22V10C family of EEPLDs. It shares architectural similarities with the ATF22V10B and AT22V10 series but incorporates advanced Flash memory technology for reprogrammability. The 'CQ' designation indicates a specific power optimization within the commercial and industrial speed grades.

Replacement Considerations

Direct replacements include other ATF22V10C variants with compatible speed grades and packages, such as ATF22V10C-15PU or ATF22V10C-15JU, provided the package footprint and electrical parameters align with the system design.
