ATF22V10CQ-15PC

Overview

The ATF22V10CQ-15PC is an Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology, utilizing Atmel Flash memory technology. It features a high-performance CMOS process with a maximum pin-to-pin propagation delay of 15 ns and a maximum operating frequency of 55.5 MHz. The device includes 10 macrocells, 22 logic inputs, and 10 bi-directional I/O pins housed in a 24-pin Plastic Dual Inline Package (PDIP). It operates on a 5V supply voltage within the industrial temperature range of -40°C to +85°C.

Feature Summary

• High-speed performance with 15 ns maximum propagation delay and 55.5 MHz external feedback frequency
• Pin-controlled power-down mode reducing standby current to less than 100 µA
• Internal input and I/O pin-keeper circuits to maintain logic states without DC current
• 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 'PC' corresponds to the 24-pin PDIP package as defined in the official datasheet documentation. Confirm compliance with RoHS standards if lead-free requirements are necessary for the target application environment.

Selection Notes

Select this component when a 15 ns speed grade is required for industrial applications (-40°C to +85°C). Ensure the design utilizes the Power-Down (PD) pin configuration via the compiler to enable low-power standby modes effectively.

Part Context

This part belongs to the ATF22V10C family of EEPLDs. It serves as a drop-in replacement for legacy GAL devices and offers reprogrammability with 100 erase/write cycles and 20-year data retention using advanced Flash technology.

Replacement Considerations

Publicly confirmed substitute part numbers include ATF22V10B-15GM/883 and ATF22V10C-15PU.

FAQ

How does the power-down feature function?

When the PD pin is driven high, the device enters power-down mode, reducing supply current to less than 100 µA while latching all output data and internal logic states.

What is the purpose of the pin-keeper circuits?

The pin-keeper circuits hold previous logic values on floating pins, preventing indeterminate states and reducing system power consumption without requiring pull-up resistors.

Is the ATF22V10CQ-15PC compatible with military temperature ranges?

No, the standard CQ-15 variant is specified for the industrial temperature range of -40°C to +85°C. Military grades require specific ordering codes such as those ending in GM/883.
