PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVERVIEW
The S3C7559/P7559 single-chip CMOS microcontroller has been designed for high-performance using
Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). The S3P7559 is a
microcontroller which has 32-kbyte one-time-programmable EPROM but its functions are same to S3C7559.
With its DTMF generator, 8-bit serial I/O interface, and versatile 8-bit timer/counters, the S3C7559/P7559 offers
an excellent design solution for a wide variety of telecommunication applications.
Up to 55 pins of the 64-pin SDIP or QFP package can be dedicated to I/O. Seven vectored interrupts provide fast
response to internal and external events. In addition, the S3C7559/P7559's advanced CMOS technology
provides for low power consumption and a wide operating voltage range.
DEVELOPMENT SUPPORT
The Samsung Microcontroller Development System, SMDS, provides you with a complete PC-based development environment for S3C7-series microcontrollers that is powerful, reliable, and portable. In addition to its
window-based program development structure, the SMDS toolset includes versatile debugging, trace, instruction
timing, and performance measurement applications.
The Samsung Generalized Assembler (SAMA) has been designed specifically for the SMDS environment and
accepts assembly language sources in a variety of microprocessor formats. SAMA generates industry-standard
hex files that also contain program control data for SMDS compatibility.

S3P7559 OTP
S3P7559OTP
OVERVIEW
The S3P7559 single-chip CMOS microcontroller is the OTP (One Time Programmable) version of the S3C7559
microcontroller. It has an on-chip OTP ROM instead of masked ROM. The EPROM is accessed by serial data
format.
The S3P7559 is fully compatible with the S3C7559, both in function and in pin configuration. Because of its
simple programming requirements, the S3P7559 is ideal for use as an evaluation chip for the S3C7559.
