ATF22LV10C-10JI

Overview

The ATF22LV10C-10JI is an industrial-grade, low-voltage Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells and up to 10 I/Os. The device operates within a supply voltage range of 3.0V to 5.5V and supports a maximum propagation delay of 10ns. It includes a user-controlled power-down pin option for standby power reduction to approximately 10µA. The component utilizes electrically erasable Flash memory technology, allowing for reprogramming and offering high reliability with 20-year data retention.

Feature Summary

• Low-voltage operation with a 3.0V to 5.5V supply range
• User-controlled power-down mode reducing standby current to 10µA typical
• 10 macrocells with variable product term architecture (8 to 16 terms per output)
• Industrial temperature range (-40°C to +85°C) with 10ns max propagation delay

Applications

• Glue logic for 3.3V systems
• DMA control circuits
• State machine control
• Graphics processing

Procurement Notes

Verify the package type matches the required application, as the 'J' suffix indicates a 28-lead PLCC package. Confirm that the design file enables the power-down feature if low standby power is required, as this configuration affects the JEDEC fuse map. Ensure programming hardware supports the specific ATF22LV10C family requirements.

Selection Notes

Select the ATF22LV10C-10JI when industrial temperature stability (-40°C to +85°C) is required alongside low-voltage compatibility. This model provides a balance of speed (10ns) and power efficiency compared to standard 5V-only PLDs. Consider the PLCC package constraints and ensure the design tool supports the Power-down compiler mode for optimal power management.

Part Context

This component belongs to the Atmel ATF22LV10C series of advanced low-voltage EEPLDs. It is part of the broader ATF22V10C family but specifically optimized for lower voltage operation down to 3.0V. The device serves as a drop-in replacement for many legacy 22V10 PAL/GAL devices while offering modern programmability and power-saving features.

Replacement Considerations

Direct functional equivalents include other ATF22LV10C variants with different packages or speeds, such as ATF22LV10C-15JI. For lead-free compliance, consider the ATF22LV10C-10JU variant which shares identical electrical characteristics but uses a green package option.
