OVERVIEW
The S3P7048 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the
S3C7044/C7048 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed
by serial data format.
The S3P7048 is fully compatible with the S3C7044/C7048, both in function and in pin configuration. Because of
its simple programming requirements, the S3P7048 is ideal for use as an evaluation chip for the
S3C7044/C7048.
