AT22LV10L-25PC

Overview

The AT22LV10L-25PC 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 supports commercial temperature ranges (0°C to 70°C) and is housed in a 24-lead Plastic Dual Inline Package (PDIP).

Feature Summary

• Low-power CMOS operation with typical current of 4 mA at VCC = 3.6V.
• Compatible with both CMOS and TTL input/output levels.
• Includes synchronous preset and asynchronous reset functionality across all registers.
• Features power-up reset circuitry for state machine initialization.

Applications

• Battery-powered systems requiring low DC power consumption.
• General-purpose logic replacement in digital circuits.
• State machine implementations utilizing preload and reset features.

Procurement Notes

Verify the package type corresponds to the 'P' suffix, indicating a 24-lead PDIP. Confirm the speed grade '25' matches the required 25 ns timing specifications. Ensure the operating environment falls within the commercial temperature range of 0°C to 70°C. Check for RoHS compliance status as original Atmel documentation may indicate non-compliance depending on manufacturing date.

Selection Notes

Select this component when a reprogrammable PLD solution is needed for complex logic functions with up to 132 product terms. Choose the AT22LV10L variant over the standard AT22LV10 if lower power dissipation is critical for battery-operated applications. Ensure the system voltage remains between 3.0V and 5.5V to maintain specified AC characteristics.

Part Context

This part belongs to the AT22LV10 family of low-voltage UV EPROM PLDs. It shares the same logic architecture as the standard AT22LV10 but offers reduced power consumption. The 'L' suffix denotes the low-power version, while '25' indicates the 25 ns speed grade. The 'PC' suffix specifies the commercial temperature range and PDIP package.

Replacement Considerations

Direct pin-compatible replacements include other AT22LV10L variants with different speed grades or packages, such as AT22LV10L-25SC (SOIC) or AT22LV10L-25JC (PLCC), provided the package footprint allows adaptation. Verify that any substitute maintains the 25 ns maximum propagation delay requirement.
