AT22LV10L-25PI

Overview

The AT22LV10L-25PI is a low-voltage UV erasable programmable logic device (PLD) manufactured by Microchip Technology. It features the familiar 22V10 architecture with 22 inputs, 10 I/Os, and 10 registered outputs. The device operates within a 3.0V to 5.5V supply range and supports industrial temperatures from -40°C to +85°C. It offers a maximum propagation delay of 25 ns and typical power consumption of 5 mA at VCC = 3.6V. Packaged in a 24-lead PDIP, it includes synchronous preset, asynchronous reset, and register preload capabilities.

Feature Summary

• Low-power CMOS operation with 5 mA typical current at 3.6V
• 22V10 compatible architecture with 10 macrocells
• Industrial temperature range (-40°C to +85°C)
• UV erasable with 2000V ESD protection

Applications

• Battery-powered systems requiring low DC power
• Complex logic replacement in industrial control
• State machine implementation with power-up reset

Procurement Notes

Verify the ordering suffix 'PI' corresponds to the 24-lead Plastic Dual Inline Package (PDIP) and Industrial temperature grade. Confirm the '-25' speed grade matches the required 25 ns maximum propagation delay specifications for the design.

Selection Notes

Select this part for applications needing UV reprogrammability with low power consumption. Ensure the system voltage stays within 3.0V to 5.5V. For higher speed requirements, consider the AT22LV10-20 variant, though it consumes more power.

Part Context

This component belongs to the AT22LV10/L family of low-voltage UV EPROM PLDs. It shares the same logic architecture as the standard AT22LV10 but offers significantly reduced power dissipation, making it suitable for battery-operated devices while maintaining CMOS and TTL compatibility.

Replacement Considerations

The AT22LV10-25PI is a direct functional substitute with identical pinout and timing but higher power consumption. Commercial grade variants like AT22LV10L-25JC are not suitable for industrial temperature ranges without derating.
