1 PRODUCT OVERVIEW
The S3C7238/C7235 single-chip CMOS microcontroller has been designed for high performance using
Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers).
With features such as LCD direct drive capability, 8-bit timer/counter, and serial I/O, the S3C7238/C7235 offer
an excellent design solution for a wide variety of applications that require LCD functions.
Up to 40 pins of the 80-pin QFP package can be dedicated to I/O. Six vectored interrupts provide fast response
to internal and external events. In addition, the S3C7238/C7235's advanced CMOS technology provides for low
power consumption and a wide operating voltage range.
The S3C7238/C7235 microcontroller is also available in OTP (One Time Programmable) version,
S3P7238/P7235. S3P7238/P7235 microcontroller has an on-chip 8/16-Kbyte one-time-programmable EPROM
instead of masked ROM. The S3P7238/P7235 is comparable to S3C7238/C7235, both in function and in pin
