AT22LV10L-25JC

Overview

The AT22LV10L-25JC is a low-voltage UV erasable programmable logic device (PLD) manufactured by Microchip Technology. It features a PAL-type architecture with 11 dedicated inputs, 10 I/O lines, and 10 macrocells providing up to 132 product terms. The device operates within a 3.0V to 5.5V supply range and delivers a maximum propagation delay of 25 ns at VCC = 3.0V. It is housed in a 28-lead Plastic J-leaded Chip Carrier (PLCC) package and supports commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Low-power CMOS operation with typical current draw of 4 mA at VCC = 3.6V
• High-speed performance with 25 ns maximum propagation delay
• UV erasable and electrically reprogrammable architecture
• CMOS and TTL compatible inputs and outputs with ±10 µA leakage

Applications

• Battery powered systems requiring low DC power consumption
• State machine initialization utilizing power-up reset and register preload
• General purpose logic replacement in commercial electronic designs

Procurement Notes

Verify the ordering suffix 'JC' corresponds to the 28-lead PLCC package and Commercial temperature range (0°C to 70°C). Confirm the speed grade '25' indicates a 25 ns maximum propagation delay. Ensure the component is sourced as an original Microchip or Atmel product to guarantee reliability and programmability testing.

Selection Notes

Select this model for applications requiring low power dissipation compared to the standard AT22LV10 variant. The 25 ns speed grade is suitable for systems operating up to approximately 32.2 MHz with external feedback. Choose the PLCC package for surface mount assembly compatibility. Verify that the 3.0V to 5.5V operating voltage aligns with the system power supply constraints.

Part Context

This component belongs to the AT22LV10 family of low-voltage UV EPROM PLDs. It shares the familiar 22V10 logic architecture but offers reduced power consumption through low-voltage CMOS technology. The device includes features such as asynchronous reset, synchronous preset, and output preload capabilities for simplified testing and state control.

Replacement Considerations

The AT22LV10-25JC serves as a higher-power alternative within the same package and speed specifications. For industrial temperature range requirements (-40°C to 85°C), the AT22LV10L-25JI is the corresponding variant. Direct pin-compatible replacements must match the 28-lead PLCC footprint and PAL-type logic structure.
