  • Product Details




    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 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.


    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 pins
