PRODUCT OVERVIEW
OVERVIEW
The S3C72N2/C72N4 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 watch timer, the S3C72N2/C72N4
offers an excellent design solution for a wide variety of applications that require LCD functions.
Up to 16 pins of the 64-pin QFP package, it can be dedicated to I/O. Four vectored interrupts provide fast
response to internal and external events. In addition, the S3C72N2/C72N4 's advanced CMOS technology
provides for low power consumption and a wide operating voltage range.
OTP
The S3C72N2/C72N4 microcontroller is also available in OTP (One Time Programmable) version, S3P72N4 .
The S3P72N4 microcontroller has an on-chip 4-Kbyte one-time-programmable EPROM instead of masked ROM.
The S3P72N4 is comparable to S3C72N2/C72N4, both in function and in pin configuration.
