PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVERVIEW
The S3C7544 single-chip CMOS microcontroller is designed for high-performance using Samsung's newest
4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).
With a versatile 8-bit timer/counter and a D/A converter, the S3C7544 offers an excellent design solution for a
wide variety of telecommunication applications.
Up to 17 pins of the 24-pin SDIP package can be dedicated to I/O. Four vectored interrupts provide fast response
to internal and external events. In addition, the S3C7544’s advanced CMOS technology has realized substantially
lower power consumption with a wide operating voltage range — all at a substantially lower cost.
OTP
The S3C7544 microcontroller is also available in OTP (One Time Programmable) version, S3P7544.
S3P7544 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM. The
S3P7544 is comparable to S3C7544, both in function and in pin configuration.

S3P7544 OTP
OVERVIEW
The S3P7544 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the S3C7544
microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data
format.
The S3P7544 is fully compatible with the S3C7544, both in function and in pin configuration. Because of its
simple programming requirements, the S3P7544 is ideal for use as an evaluation chip for the S3C7544.

OPERATING MODE CHARACTERISTICS
When 12.5 V is supplied to the VPP(TEST) pin of the S3P7544, the EPROM programming mode is entered. The
operating mode (read, write, or read protection) is selected according to the input signals to the pins listed in
Table 16-3 below.

NOTES:
1. During oscillator stabilization wait time, all CPU operations must be stopped to avoid instability during oscillator
start-up.
2. Use the basic timer mode register (BMOD) interval timer to delay the execution of CPU instructions during the wait time.
