AT22LV10-25JI

Overview

The AT22LV10-25JI is a low-voltage UV erasable programmable logic device (PLD) manufactured by Microchip Technology. It features a 28-lead Plastic J-leaded Chip Carrier (PLCC) package and supports an industrial operating temperature range of -40°C to +85°C. The device operates within a 3.0V to 5.5V supply voltage range, delivering a maximum propagation delay of 25 ns at VCC = 3.0V. It utilizes high-reliability CMOS technology with 2000V ESD protection and includes 10 macrocells with variable product terms for complex logic implementation.

Feature Summary

• Low-power 3-volt CMOS operation with wide power supply range from 3.0V to 5.5V
• High-speed performance with 25 ns maximum propagation delay
• Industrial temperature rating spanning -40°C to +85°C
• Familiar 22V10 logic architecture with 10 macrocells and synchronous preset/asynchronous reset capabilities

Applications

• Battery-powered systems requiring low DC power consumption
• Complex logic replacement in digital circuits
• State machine initialization and control logic
• General-purpose programmable logic applications

Procurement Notes

Verify the ordering suffix 'JI' corresponds to the 25 ns speed grade and Industrial temperature range (-40°C to +85°C). Confirm the package type is the 28-lead PLCC. Ensure compatibility with UV erasure equipment if reprogramming is required. Check for RoHS compliance status as per specific manufacturing batches.

Selection Notes

Select the AT22LV10-25JI when industrial temperature stability is required alongside 25 ns timing constraints. Compare against the AT22LV10L variant if lower static current consumption is critical, noting that the standard AT22LV10 draws higher supply current. Ensure the design accommodates the 28-pin PLCC footprint and UV window access for field erasure if applicable.

Part Context

This component belongs to the AT22LV10 family of low-voltage UV EPROM PLDs. It shares the same logical architecture as the standard 22V10 but offers improved speed and lower voltage operation. The 'I' suffix denotes the industrial temperature grade, while 'J' specifies the PLCC package. It serves as a drop-in replacement for older 5V-only PLDs in designs supporting 3.3V or 5V supplies.

Replacement Considerations

The AT22LV10-25PC (PDIP) or AT22LV10-25SC (SOIC) offer identical electrical specifications in different packages. For lower power requirements, consider the AT22LV10L-25JI, which maintains the same pinout and logic function but reduces typical supply current significantly.
