OVERVIEW
The S3C72B5/C72B7/C72B9 single-chip CMOS microcontroller has been designed for high performance using Samsung's newest 4-bit CPU core, SAM47 (Samsung Arrangeable Microcontrollers). With an up-to-1280-dot LCD direct drive capability, segment expandable circuit, 8-bit and 16-bit timer/counter, and serial I/O, the S3C72B5/C72B7/C72B9 offers an excellent design solution for a wide variety of applications which require LCD functions. Up to 51 pins of the 128-pin QFP package can be dedicated to I/O. Nine vectored interrupts provide fast response to internal and external events. In addition, the S3C72B5/C72B7/C72B9's advanced CMOS technology provides for low power consumption and a wide operating voltage range.
The S3C72B5/C72B7/C72B9 microcontroller is also available in OTP (One Time Programmable) version, S3P72B9. S3P72B9 microcontroller has an on-chip 32-Kbyte one-time-programmable EPROM instead of masked ROM. The S3P72B9 is comparable to S3C72B5/C72B7/C72B9, both in function and in pin configuration except ROM size.
