ATF22V10CQ-15PI

Overview

The ATF22V10CQ-15PI is an Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells and 10 I/O pins in a 24-pin Plastic Dual Inline Package (PDIP). The device specifies a maximum pin-to-pin propagation delay of 15 ns and a clock-to-output delay of 8.0 ns. It operates on a 5V supply, supporting Industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a typical standby power consumption of 35 µA and a maximum active current of 70 mA.

Feature Summary

• High-speed performance with 15 ns maximum propagation delay
• Pin-controlled Power-Down mode reducing current to <100 µA
• Internal input and I/O pin-keeper circuits for state retention
• 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 package type matches the required footprint, as this model uses a 24-lead PDIP. Confirm that the design utilizes the Power-Down feature via the PD pin configuration, as this affects the JEDEC file generation. Ensure the operating environment falls within the specified industrial temperature range of -40°C to +85°C.

Selection Notes

Select this component when a 15 ns speed grade is sufficient for the application timing requirements. The CQ suffix indicates support for the Power-Down mode, which is essential for low-power designs requiring pin-controlled standby. Compare against the standard ATF22V10C-15PU if Power-Down functionality is not needed, or consider faster grades like the -10JU if higher frequency operation is required.

Part Context

This part belongs to the ATF22V10C family of EEPLDs, utilizing advanced Flash memory technology for reprogrammability. It offers 100% testing and high reliability with 20-year data retention. The device supports full military, commercial, and industrial temperature ranges and includes features such as asynchronous reset and synchronous preset capabilities.

Replacement Considerations

The ATF22V10C-15PU is a direct functional substitute without Power-Down support. For lower delay requirements, the ATF22V10C-10JU or ATF22V10C-10PU may be used. Legacy compatible parts include the ATF22V10B-15PU.
