ATF22V10C-10XU

Overview

The ATF22V10C-10XU is an electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology, utilizing Atmel Flash memory technology. It features a 24-lead TSSOP package and operates within the industrial temperature range of -40°C to +85°C. The device provides 10 macrocells, 18 inputs, and 10 I/O lines with a maximum propagation delay of 10 ns. It functions at a supply voltage of 5V ± 10% and supports up to 125 MHz operation.

Feature Summary

• High-speed performance with 10 ns maximum pin-to-pin delay
• Electrically erasable Flash memory allowing 100 erase/write cycles
• Pin-controlled standby power mode reducing current to 10 µA typical
• Internal input and I/O pin-keeper circuits for state retention

Applications

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

Procurement Notes

Verify that the component meets RoHS compliance standards as indicated by the 'Green Package Options'. Confirm the specific ordering suffix matches the required industrial temperature range (-40°C to +85°C). Ensure the design file configuration aligns with the selected compiler mode if power-down functionality is utilized.

Selection Notes

Select this part for applications requiring 10 macrocells and high-speed logic in an industrial environment. Compare against the ATF22V10C-7PX for faster commercial-grade performance or the ATF22V10B series for backward compatibility with older Atmel architectures. Consider the TSSOP package constraints for PCB layout.

Part Context

This component belongs to the ATF22V10C family of EEPLDs. It is backward-compatible with the Atmel ATF22V10B(Q) and AT22V10(L) devices. The 'XU' suffix denotes the 24-lead TSSOP package and the industrial temperature grade, distinguishing it from commercial or military variants.

FAQ

How does the device handle floating pins?

The ATF22V10C includes internal input and I/O pin-keeper circuits that hold the previous logic state when pins are not driven, preventing indeterminate levels without DC current draw.

What is the power consumption in standby mode?

When the PD pin is asserted high, the device enters power-down mode, reducing the supply current to a typical value of 10 µA.

Is the device reprogrammable?

Yes, the device utilizes advanced Flash technology that allows for 100 erase/write cycles and is fully tested for reprogrammability.
