ATF22LV10C-10PI

Overview

The ATF22LV10C-10PI is an industrial-grade, low-voltage Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features a high-performance CMOS architecture with 10 macrocells and supports up to 12 inputs and 10 I/Os. The device operates within a supply voltage range of 3.0V to 5.5V and delivers a maximum propagation delay of 10ns. It includes a user-controlled power-down pin option for reduced standby current and utilizes electrically erasable Flash memory technology for reprogrammability.

Feature Summary

• Low-voltage operation with a 3.0V to 5.5V supply range
• Maximum propagation delay of 10ns at industrial temperatures
• User-controlled power-down mode reduces standby current to less than 100µA
• CMOS and TTL compatible inputs and outputs

Applications

• Glue logic for 3.3V systems
• DMA control circuits
• State machine control
• Graphics processing

Procurement Notes

Verify the package type corresponds to the 'P' suffix, indicating a 24-lead Plastic Dual In-line Package (PDIP). Confirm that the 'I' suffix matches the required industrial temperature range of -40°C to +85°C. Ensure programming equipment supports the specific JEDEC file format generated for the power-down mode if utilized in the design.

Selection Notes

Select this component when a low-voltage PLD solution is required for industrial environments. The 10ns speed grade is suitable for applications needing moderate switching speeds. Consider the PDIP package only if through-hole mounting is necessary; surface-mount alternatives like SOIC or TSSOP are available with different ordering suffixes.

Part Context

This part belongs to the ATF22LV10C family of high-performance EEPLDs. It shares architectural similarities with the standard ATF22V10C but offers optimized low-voltage operation down to 3.0V. The 'PI' designation specifically identifies the industrial temperature variant housed in a 24-pin DIP package.

Replacement Considerations

Direct functional replacements include other ATF22LV10C variants with different packages (e.g., ATF22LV10C-10SI for SOIC) or speed grades (e.g., ATF22LV10C-15PI). Cross-family PAL/GAL devices may require logic restructuring due to differences in product term allocation.
