AT22LV10L-25SI

Overview

The AT22LV10L-25SI is a low-voltage UV erasable programmable logic device (PLD) manufactured by Microchip Technology. It features a 22V10 architecture with 22 inputs, 10 I/O lines, and 10 registered outputs in a 24-lead SOIC package. Operating at 3.0V to 5.5V, it delivers a maximum propagation delay of 25 ns and supports industrial temperatures from -40°C to 85°C. Key electrical characteristics include a typical supply current of 4 mA at 3.6V, full CMOS output levels, and 10 µA maximum leakage. The device includes synchronous preset and asynchronous reset capabilities.

Feature Summary

• Low-power 3-volt CMOS operation with 1 mA typical supply current at VCC = 3.3V
• High-speed performance with 25 ns maximum propagation delay
• Industrial temperature range availability (-40°C to +85°C)
• CMOS and TTL compatible inputs and outputs with 10 µA leakage maximum

Applications

• Battery powered systems requiring low DC power consumption
• State machine initialization utilizing power-up reset and register preload
• Complex logic function realization using up to 16 product terms per output

Procurement Notes

Verify the ordering code matches the specific speed grade and package configuration required for the design. Confirm that the Industrial temperature rating (-40°C to 85°C) aligns with environmental specifications. Ensure programming equipment supports UV erasure protocols and voltage requirements for the PLCC or SOIC variant being utilized.

Selection Notes

Select the AT22LV10L-25SI over the standard AT22LV10-25SI when system power constraints are critical, as the 'L' variant offers significantly lower quiescent current. Verify that the 25 ns timing meets the maximum clock frequency requirements of the application. Ensure the 24-lead SOIC footprint is compatible with the PCB layout constraints.

Part Context

This component belongs to the AT22LV10 family of low-voltage UV EPROM PLDs. It shares the same logic architecture as the AT22LV10 but is optimized for lower power dissipation. The 'SI' suffix denotes the Industrial temperature range and the 24-lead Small Outline Integrated Circuit (SOIC) package format.

Replacement Considerations

The AT22LV10-25SI is a functional equivalent with higher power consumption. Cross-referencing with other 22V10 architecture PLDs requires verification of pin compatibility and timing parameters.
