Samsung S3C9228/P9228 사용자 설명서

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.
