ATF22LV10CZ-25SC

Overview

The ATF22LV10CZ-25SC is a high-performance Electronically Erasable Programmable Logic Device (EEPLD) manufactured by Atmel. It utilizes CMOS technology and features a PAL-type architecture with 10 macrocells. The device offers a maximum propagation delay of 25 ns and supports a maximum operating frequency of 33.3 MHz. It provides 11 dedicated inputs and 10 I/O lines, totaling 22 inputs/outputs. The component operates within a voltage range of 2.7 V to 5.5 V and is housed in a 24-pin SOIC package.

Feature Summary

• 10 Macrocells with flexible output logic macrocell (OLMC) configurations
• High-speed performance with 25 ns max propagation delay
• Electrically erasable and reprogrammable Flash memory technology
• Single voltage supply operation from 2.7 V to 5.5 V

Applications

• Complex glue logic replacement
• Address decoding and control logic
• State machine implementation
• Bus interface protocols

Procurement Notes

Verify the specific suffix 'SC' against official Microchip documentation to confirm the exact package variant and temperature grade, as suffixes can denote specific tape-and-reel or industrial/commercial ratings. Ensure compliance with RoHS directives if required for the target assembly process.

Selection Notes

Select this component when a non-volatile, reprogrammable solution is needed for moderate complexity logic functions. Compare against UV-erasable PLDs if frequent field updates are not required. Consider the ATF22V10 series for standard voltage applications if lower power consumption is not critical.

Part Context

This part belongs to the ATF22LV10 family of EEPLDs, designed to replace complex discrete logic gates. It bridges the gap between simple GALs and more complex CPLDs, offering ease of use with standard JEDEC programming voltages and electrical erasure capabilities via standard programmers.

Replacement Considerations

Direct pin-compatible replacements include the ATF22V10CZ-25SC (standard voltage) and ATF22LV10CZ-25SU (SOIC-24). Verify voltage levels carefully when substituting LV variants with standard voltage parts.
