ATF22V10C-10GM/883

Overview

The ATF22V10C-10GM/883 is a high-performance CMOS electrically erasable programmable logic device (EEPLD) manufactured by Microchip Technology. It features 10 macrocells, 10 I/O pins, and a maximum propagation delay of 10 ns. The device operates at a supply voltage of 5 V ± 10% and supports a military temperature range from -55°C to +125°C. It utilizes advanced Flash technology for reprogrammability and includes pin-controlled standby power with typical current consumption of 10 µA.

Feature Summary

• High-speed performance with 10 ns maximum pin-to-pin delay
• Electrically erasable Flash memory technology allowing 100 erase/write cycles
• Pin-controlled power-down mode reducing supply current to less than 100 µA
• Military-grade reliability with 20-year data retention and 200 mA latch-up immunity

Applications

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

Procurement Notes

Verify the package type matches the required application, as this part uses a 24-lead Ceramic Dual Inline Package (CERDIP). Confirm that the design file enables the power-down feature if low-power operation is required, as the PD pin configuration depends on the compiler mode selection during programming.

Selection Notes

Select this component for designs requiring military temperature stability (-55°C to +125°C) and high-speed logic operations. Ensure the system power supply adheres to the 5V ± 10% specification. Consider the 10 macrocell capacity and 10 I/O limits when mapping logic functions to avoid resource exhaustion.

Part Context

This device belongs to the ATF22V10C series of EEPLDs. It is backward-compatible with Atmel ATF22V10B(Q) and AT22V10(L) devices. The '/883' suffix indicates compliance with DSCC drawing specifications for military-grade components.

FAQ

How does the power-down mode function?

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

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

The pin-keeper circuits hold inputs to their previous logic states when not actively driven, preventing floating pins and reducing system power consumption.

Can the security fuse be programmed before other fuses?

No, the security fuse should be programmed last because its effect is immediate, inhibiting fuse verify and preload functions once set.
