S3C8/S3F8-SERIES MICROCONTROLLERS
Samsung's S3C8/S3F8-series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various flash memory ROM sizes. Important CPU features include:
- Efficient register-oriented architecture
- Selectable CPU clock sources
- Idle and Stop power-down mode release by interrupts
- 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 four CPU clocks) can be assigned to specific interrupt levels.

S3F80JB MICROCONTROLLER
The S3F80JB single-chip CMOS microcontroller is fabricated using a highly advanced CMOS process and is based on Samsung's newest CPU architecture.

The S3F80JB is the microcontroller which has 64-Kbyte Flash Memory ROM.

Using a proven modular design approach, Samsung engineers developed S3F80JB by integrating the following peripheral modules with the powerful SAM8 RC core:
- Internal LVD circuit and 16 bit-programmable pins for external interrupts.
- One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
- One 8-bit Timer/counter with three operating modes.
- Two 16-bit timer/counters with selectable operating modes.
- 4-bit analog voltage comparator with four/three channels (internal/external reference).
- One 8-bit counter with auto-reload function and one-shot or repeat control.

The S3F80JB is a versatile general-purpose microcontroller, which is especially suitable for use as remote transmitter controller. It is currently available in a 32-pin SOP and 44-pin QFP package.
