S3C70F2/C70F4/P70F4
S3P70F4 OTP
16 S3P70F4 OTP
OVERVIEW
The S3P70F4 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the
S3C70F2/C70F4 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed
by serial data format.
The S3P70F4 is fully compatible with the S3C70F2/C70F4, both in function and in pin configuration. Because of
its simple programming requirements, the S3P70F4 is ideal for use as an evaluation chip for the
S3C70F2/C70F4.
