21-S3-C831B/P831B-062003 USER'S MANUAL www.DataSheet4U.com S3C831B/P831B 8-Bit CMOS Microcontroller Revision 1 S3C831B/P831B PRODUCT OVERVIEW 1 PRODUCT OVERVIEW S3C8-SERIES MICROCONTROLLERS Samsung's S3C8 series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various mask-programmable ROM sizes. Among the major CPU features are: — Efficient register-oriented architecture — Selectable CPU clock sources — Idle and Stop power-down mode release by interrupt — Built-in basic timer with watchdog function A sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more interrupt sources and vectors. Fast interrupt processing (within a minimum of four CPU clocks) can be assigned to specific interrupt levels. S3C831B MICROCONTROLLER www.DataSheet4U.com The S3C831B single-chip microcontroller are fabricated using the highly advanced CMOS process. Its design is based on the powerful SAM88RC CPU core. Stop and idle (power-down) modes were implemented to reduce power consumption. The S3C831B is a microcontroller with a 64K-byte mask-programmable ROM embedded. The S3P831B is a microcontroller with a 64K-byte one-time-programmable ROM embedded. Using the SAM88RC modular design approach, the following peripherals were integrated with the SAM88RC CPU core: — Large number of programable I/O ports (Total 72 pins) — PLL frequency synthesizer — 16-bits intermediate frequen...
