PRODUCT OVERVIEW
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.
OTP
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.
