AT22LV10-20PI

Overview

The AT22LV10-20PI is a low-voltage UV-erasable programmable logic device (PLD) manufactured by Microchip Technology. It features a 22V10 architecture with 22 inputs and 10 bidirectional I/Os in a 24-pin PDIP package. The device operates within a 3.0V to 5.5V supply range, delivering a maximum propagation delay of 20 ns at VCC = 3.0V. It supports industrial temperature ranges (-40°C to +85°C), offers CMOS/TTL compatibility, and includes synchronous preset and asynchronous reset capabilities across all ten macrocells.

Feature Summary

• Low-voltage operation with a wide power supply range of 3.0V to 5.5V
• High-speed performance with a maximum 20 ns propagation delay
• Industrial temperature rating from -40°C to +85°C
• UV-erasable reprogrammability with security fuse protection

Applications

• Battery-powered systems requiring low power consumption
• Complex combinational and registered logic implementations
• State machine initialization and control logic
• General-purpose digital logic replacement

Procurement Notes

Verify the ordering suffix 'PI' corresponds to the Industrial temperature range (-40°C to +85°C) and the 24-lead Plastic Dual Inline Package (PDIP). Confirm that the specific speed grade matches the required timing constraints for the target application design.

Selection Notes

Select this component when a 22-input, 10-output PLD with registered outputs is needed. Ensure the system voltage falls between 3.0V and 5.5V. Consider the AT22LV10L variant if lower static power dissipation is critical, as it draws significantly less current than the standard AT22LV10.

Part Context

This device belongs to the AT22LV10 family of low-voltage UV-erasable PLDs. It shares the same logic architecture as the standard AT22V10 but is optimized for lower voltage operation. The 'I' suffix denotes industrial temperature capability, while 'P' indicates the PDIP package style.

Replacement Considerations

The AT22LV10-20JI serves as the commercial temperature equivalent. For lower power requirements, the AT22LV10L-25PI is an alternative, though it has a slower 25 ns speed grade. Direct pin-compatible replacements from other manufacturers may require verification of logic array structure.
