OVERVIEW OF S3F84B8 MICROCONTROLLER

1.1 S3C8-SERIES MICROCONTROLLERS
Samsung's SAM8RC family of 8-bit single-chip CMOS microcontrollers offer a fast and efficient CPU, a wide
range of integrated peripherals, and various mask-programmable ROM sizes. Owing to its address/data bus
architecture and a large number of bit-configurable I/O ports, these microcontrollers provide a flexible
programming environment for applications with varied memory and I/O requirements. To support real-time
operations, timer/counters with selectable operating modes are included.
1.1.1 S3F84B8 MICROCONTROLLER
The S3F84B8 single-chip CMOS microcontrollers are designed using a highly advanced CMOS process
technology based on Samsung's latest CPU architecture.
S3F84B8 specifies a microcontroller with built-in 8K-byte full-flash ROM.
Using a proven modular design approach, Samsung S3F84B8 integrates the following peripheral modules with a
powerful SAM8 RC core:

3 configurable I/O ports (18 pins)

17 interrupt sources with 17 vectors and 6 interrupt levels

1 watchdog timer function (Basic Timer)

1 basic timer (8-bit) for oscillation stabilization

3 timer/counters (8-bit) with Time Interval, PWM, and Capture modes (Timer C and Timer D can be used for
16-bit Timer 0)

1 timer/counter (16-bit) with 2 operating modes: Interval timer mode and PWM mode (If Timer C and Timer D
are used for Timer 0, S3F84B8 has 1 Timer0 (16-bit))

Analog to digital converter with 8 input channels and 10-bit resolution

1 BUZ for programmable frequency output

High current LED drive I/O ports (High current output: Typical 12 mA)
The S3F84B8 microcontroller is ideal for use in a wide range of home applications requiring simple timer/counter,
ADC, and so on. They are currently available in 20-pin SOP/DIP package.
