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.

  
The S3C8238/C8235/F8235 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS
process, based on Samsung’s latest CPU architecture.
The S3C8235 is a microcontroller with a 16K-byte mask-programmable ROM embedded.
The S3F8235 is a microcontroller with a 16K-byte Flash ROM embedded.
Using a proven modular design approach, Samsung engineers have successfully developed the
S3C8238/C8235/F8235 by integrating the following peripheral modules with the powerful SAM8 core:
— Five programmable I/O ports, including three 8-bit ports and two 4-bit ports, for a total of 32 pins.
— Eight 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 one 16-bit timer/counter with selectable operating modes.
— Watch timer for real time
— 8-channel A/D converter
The S3C8238/C8235/F8235 is versatile microcontroller for camera, LCD and ADC application, etc. They are
currently available in 64-pin LQFP, 64-pin QFP and 64-pin SDIP package.
