18 S3P9228 OTP

OVERVIEW

The S3P9228 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the S3C9228 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data format.

The S3P9228 is fully compatible with the S3C9228, both in function and in pin configuration. Because of its simple programming requirements, the S3P9228 is ideal for use as an evaluation chip for the S3C9228.
