1 PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVERVIEW
The S3C72E8/P72E8 is a SAM47 core-based 4-bit CMOS single-chip microcontroller. It has a timer/counter and
LCD drivers.
The S3P72E8 is especially suited for use in data bank, telephone and LCD general purpose.
It is built around the SAM47 core CPU and contains ROM, RAM, 39 I/O lines, programmable timer/counter,
buzzer output, enough LCD dot matrix, and segment drive pins.
The S3C72E8/P72E8 can be used for dedicated control functions in a variety of applications, and is especially
designed for multi data bank, telephone and LCD game.
OTP
The S3C72E8 microcontroller is also available in OTP (One Time Programmable) version, S3P72E8. S3P72E8
microcontroller has an on-chip 8 K-byte one-time-programable EPROM instead of masked ROM. The S3P72E8
is comparable to S3C72E8, both in function and in pin configuration.
