PRODUCT OVERVIEW
S3C8-SERIES MICROCONTROLLERS
Samsungs 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 functionA 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
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 frequency counter
— Two synchronous SIO modules
— Two 8-bit timer/counters
— One 16-bit timer/counter
— Low voltage reset
— A/D converter with 8 selectable input pinsFEATURES
