Features, Applications

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. 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.

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 S3C7414/C7424/C7434, in function, in D.C. electrical characteristics and in pin configuration.

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.
