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.

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. The key features of S3F84B8 include :
