S3P9678 OTP
OVERVIEW
The S3P9678 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the
S3C9674/C9678 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed
by serial data format.
The S3P9678 is fully compatible with the S3C9674/C9678, both in function and in pin configuration. Because of
its simple programming requirements, the S3P9678 is ideal for use as an evaluation chip for the
S3C9674/C9678.
