ATF22V10C-10PC

Overview

The ATF22V10C-10PC 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. The device offers a maximum pin-to-pin propagation delay of 10 ns and operates at a maximum frequency of 90 MHz. It functions on a 5 V power supply, drawing up to 140 mA in active mode and approximately 10 µA in standby. The component supports full industrial temperature ranges (-40°C to +85°C) and includes features such as pin-controlled power-down, input pin-keepers, and a security fuse.

Feature Summary

• High-speed performance with 10 ns max propagation delay and 90 MHz max frequency
• 10 Macrocells with 10 bi-directional I/O pins
• Pin-controlled power-down mode reducing current to <100 µA
• Internal input pin-keeper circuits to prevent floating states

Applications

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

Procurement Notes

Verify the package type against the ordering code suffix. The datasheet lists standard packages including PDIP (P), SOIC (S), TSSOP (X), PLCC (J), and LCC (L). A 'C' suffix typically denotes commercial temperature range, but confirm specific package availability with the manufacturer or distributor documentation to ensure compatibility with the intended PCB footprint.

Selection Notes

Select this part for applications requiring reprogrammable logic with low standby power. Ensure the design utilizes the Power-Down (PD) pin if low-power operation is critical, as it must be enabled in the compiler mode selection. Verify that the 5V ±10% supply tolerance meets system requirements for industrial environments.

Part Context

This component belongs to the ATF22V10C family of EEPLDs. It is backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices. The technology uses advanced Flash memory, allowing for 100 erase/write cycles and 20-year data retention. It is designed for high-reliability applications with 200mA latch-up immunity.

FAQ

How does the Power-Down mode function?

When the PD pin is driven high, the device enters power-down mode, reducing supply current to less than 100 µA. All output data and internal logic states are latched and held during this period.

What is the purpose of the input pin-keeper circuits?

The pin-keeper circuits hold the previous logic state of each pin when not actively driven, preventing inputs from floating to indeterminate levels and reducing system power consumption.

Can the ATF22V10C-10PC be used in military temperature ranges?

No, the standard ATF22V10C-10PC is rated for industrial temperatures (-40°C to +85°C). Military grade versions (e.g., -55°C to +125°C) require specific ordering codes such as ATF22V10C-10GM/883.
