ATF22V10C-15SC

Overview

The ATF22V10C-15SC is a high-performance Electrically Erasable Programmable Logic Device (EEPLD) manufactured by Atmel. It features a PAL-type architecture with 10 macrocells, 22 inputs, and 10 I/O lines. The device operates at a maximum frequency of 66.7 MHz with a typical propagation delay of 15 ns. It supports a 5 V supply voltage and includes features such as register preload, power-up reset, and shared input/clock capabilities. The component is housed in a 24-pin PDIP package.

Feature Summary

• PAL-type EEPLD architecture with 10 macrocells
• 22 dedicated inputs and 10 I/O lines
• 15 ns propagation delay and 66.7 MHz max frequency
• Register preload and power-up reset functionality

Applications

• General-purpose digital logic replacement
• State machine implementation
• Address decoding and control logic

Procurement Notes

Verify the manufacturer origin, as Atmel was acquired by Microchip Technology. Confirm the specific suffix 'SC' corresponds to the intended temperature range and package variant against official datasheets. Ensure compliance with RoHS directives if required for the target application, noting that older Atmel parts may have different environmental certifications than current Microchip equivalents.

Selection Notes

Select this part when a non-volatile programmable logic solution is required with 10 macrocells and 22 inputs. Compare the 15 ns speed grade against faster variants like the -10 or -15C series if timing constraints are tight. Ensure the PDIP-24 package fits the board layout requirements. Verify voltage compatibility with the system's 5 V logic levels.

Part Context

This component belongs to the ATF22V10 family of high-performance EEPLDs. It serves as a drop-in replacement for complex GALs and standard PLDs. The 'C' suffix typically denotes commercial temperature range specifications, while 'SC' indicates the specific package and speed grade combination within the Atmel product line.

Replacement Considerations

Microchip Technology ATF22V10C-15SC is the direct successor. Cross-reference with ATF22V10B-15SC for military temperature grades if needed.
