1 PRODUCT OVERVIEW
PRODUCT OVERVIEW
OVERVIEW
The S3C7414/C7424/C7434 single-chip CMOS microcontroller has been designed for very high performance
using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontroller).
With an A/D converter, LED direct drive pins, an 8-bit serial I/O interface, and an 8-bit timer/counter, the
S3C7414/C7424/C7434 offers you an excellent design solution for a wide variety of home appliance applications
— electric fans, cookers, boilers, and air conditioners, for example.
Up to 35 pins of the 42-pin SDIP or 44-pin QFP package can be dedicated to I/O. Seven vectored interrupts
provide fast response to internal and external events.
In addition, the S3C7414/C7424/C7434's advanced CMOS technology provides for low power consumption and a
wide operating voltage range.
OTP
The S3C7414/C7424/C7434 microcontroller is also available in OTP (One Time Programmable) version,
S3P7414/P7424/P7434. S3P7414/P7424/P7434 microcontroller has an on-chip 4-Kbyte one-time-programmable
EPROM instead of masked ROM. The S3P7414/P7424/P7434 is comparable to S3C7414/C7424/C7434, in
function, in D.C. electrical characteristics and in pin configuration.
DEVELOPMENT SUPPORT
The Samsung Microcontroller Development System, SMDS, provides you with a complete PC-based develop-
ment 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.
