S3P9404/P9414 OTP

OVERVIEW

The S3P9404/P9414 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the

S3C9404/C9414 microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed

by serial data format.

The S3P9404/P9414 is fully compatible with the S3C9404/C9414 , both in function and in pin configuration.

Because of its simple programming requirements, the S3P9404/P9414 is ideal for use as an evaluation chip for

the S3C9404/C9414 .
