S3F84I9X MICROCONTROLLER
  The S3F84I9X is a microcontroller with a 32K-byte Full Flash ROM embedded.
  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. The major CPU features are:
  - Efficient register-oriented architecture
  - Selectable CPU clock sources
  - Idle and Stop power-down mode released by interrupt or reset
  - 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.
  - Five programmable I/O ports (42SDIP: 32pins, 44QFP: 34pins) including ports shared with segment/common drive outputs.
  - Four bit-programmable pins for external interrupts.
  - One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
  - Two 8-bit timer/counter and Two 16-bit timer/counter with selectable operating modes.
  - One asynchronous UART and One synchronous SIO
  - One 10-bit PWM output
  - 10-bit 8-channel A/D converter
  - Watch timer for real time
