S3C7544/P7544
PRODUCT OVERVIEW
1 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.
