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.

S3F84NB MICROCONTROLLER
The S3F84NB single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process technology based on Samsung’s latest CPU architecture.

The S3F84NB is a microcontroller with 64K-byte flash memory embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3F84NB by integrating the following peripheral modules with the powerful SAM8 core:

• Seven programmable I/O ports, including seven 8-bit ports for a total of 56 pins.
• Fourteen bit-programmable pins for external interrupt.
• One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
• Four 8-bit timer/counter and two 16-bit timer/counter with selectable operating modes.
• Two asynchronous UART
• One synchronous SIO
• One Watch timer for real-time clock
• One Pattern generation Module
• 10-bit 8-channel A/D converter

The S3F84NB is versatile microcontroller for home appliances and ADC applications, etc. They are currently available in 64-pin QFP and 64-pin SDIP package.
