COP8SAC728M8

Overview

The COP8SAC728M8 is an 8-bit CMOS microcontroller from the COP8SA family, featuring 4k bytes of OTP EPROM and 128 bytes of RAM. It utilizes a modified Harvard architecture with a 1 µs instruction cycle time at 10 MHz CKI. The device includes a 16-bit timer/counter, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic. Operating voltage ranges from 2.7V to 5.5V across industrial temperature grades. It is housed in a 28-pin DIP package.

Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm specific ordering suffixes match required temperature ranges and package types. Check datasheet revisions for any electrical characteristic updates before finalizing designs.

Selection Notes

Select based on memory requirements and pin count availability within the 28-pin package. Ensure clock source configuration matches system timing needs. Verify that the OTP programming tools are compatible with the selected windowed or non-windowed variants if development flexibility is required.

Part Context

This component belongs to the COP8SA family, which serves as a supersets of the older COP800 series. It offers enhanced integration with low EMI features and small packaging options. The family supports both ROM and OTP technologies for flexible manufacturing and prototyping strategies.

Replacement Considerations

COP8SAC728N9 is a documented alternative offering identical specifications but operating within the 0°C to +70°C commercial temperature range instead of the industrial grade.
