The S3C7324 single-chip CMOS microcontroller has been designed for high performance using Samsung's
newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).
With features such as LCD direct drive capability, 4-channel A/D converter, 24-bit AM/FM frequency counter and
watch timer, the S3C7324 offers an excellent design solution for a wide variety of applications that require LCD
functions and audio applications.
Up to 32 pins of the 64-pin QFP package, it can be dedicated to I/O. Five vectored interrupts provide fast
response to internal and external events. In addition, the S3C7324 's advanced CMOS technology provides for
low power consumption and a wide operating voltage range.
OTP
The S3C7324 microcontroller is also available in OTP (One Time Programmable) version, S3P7324 . The
S3P7324 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The
S3P7324 is comparable to S3C7324, both in function and in pin configuration.

OVERVIEW
The S3P7324 single-chip CMOS microcontroller is the OTP (One Time Programmable)version of the
S3C7324microcontroller. It has an on-chip EPROM instead of masked ROM. The EPROM is accessed by a serial
data format.
The S3P7324 is fully compatible with the S3C7324, both in function and in pin configuration. Because of its
simple programming requirements, the S3P7324 is ideal for use as an evaluation chip for the S3C7324.
