Description

The S3C7044/C7048/S3P7048 single-chip CMOS microcontroller has been designed for very high-performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).

The S3P7048 is the microcontroller which has 8K-bytes one-time-programmable ROM and the functions are same to S3C7044/C7048/S3P7048.

With two 8-bit timer/counters, an 8-bit serial I/O interface, and eight software n-channel open-drain I/O pins, the S3C7044/C7048/S3P7048 offers an excellent design solution for a wide variety of general-purpose applications.

Up to 36 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 S3C7044/C7048/S3P7048's advanced CMOS technology provides for low power consumption and a wide operating voltage range.
