ATF22V10CQ-15JU

Overview

The ATF22V10CQ-15JU is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 18 inputs, and 10 I/Os in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package. The device operates at a maximum propagation delay of 15 ns with a typical standby power consumption of 35 µA. It utilizes advanced Flash technology for reprogrammability and supports a supply voltage range of 4.75 V to 5.25 V.

Feature Summary

• High-speed performance with a maximum pin-to-pin delay of 15 ns
• Pin-controlled standby power mode reducing current to less than 100 µA
• Internal input and I/O pin-keeper circuits to maintain 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 the component originates from an authorized source due to potential export restrictions associated with this part number. Confirm that the PLCC-28 package matches the design requirements. Ensure the programming environment supports the specific JEDEC file format generated for the CQ-15 speed grade and industrial temperature range.

Selection Notes

Select the ATF22V10CQ-15JU when an industrial temperature range (-40°C to +85°C) and lower standby power are required compared to standard commercial variants. The 'CQ' designation indicates the inclusion of the power-down feature enabled via the PD pin. Verify that the 15 ns delay meets the system timing constraints for the intended application frequency.

Part Context

This component belongs to the ATF22V10C family of EEPLDs, which utilize CMOS Flash memory technology. The 'CQ' suffix denotes the industrial-grade version with power-down capability, while '15' specifies the 15 ns speed grade. The 'JU' suffix identifies the 28-lead PLCC package configuration.

Replacement Considerations

The ATF22V10C-15JU serves as a direct functional replacement if the power-down feature is not utilized in the design. For military applications requiring extended temperature ranges, the ATF22V10C-15GM/883 is a compatible alternative.
