S3F8-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 flash memory ROM sizes.

An address/data bus architecture and a large number of bit-configurable I/O ports provide a flexible programming environment for applications with varied memory and I/O requirements. Timer/counters with selectable operating modes are included to support real-time operations.

S3F84A5 MICROCONTROLLER
The S3F84A5 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process technology based on Samsung’s latest CPU architecture.

The S3F84A5 is a microcontroller with a 16K-byte full-flash ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3F84A5 by integrating the following peripheral modules with the powerful SAM8 RC core:

• Four configurable I/O ports (24 pins)
• Seventeen interrupt sources with seventeen vectors and eight interrupt levels
• One watchdog timer function (Basic Timer overflow)
• One 8-bit basic timer for oscillation stabilization
• Two 8-bit timer/counter with time interval, PWM, and Capture mode
  (Timer B with interval and "8+2" bit PWM mode)
• One 16-bit timer/counter with three operating modes; Interval timer, Capture and PWM mode
• Analog to digital converter with 8 input channels, integrated sample and hold circuit, event trigger to start A/D converter conversion, and 10-bit resolution.
• 8-bit Pulse width modulation, up & down counting, 6 output channels with two compare units, 3 PWM interrupt sources.
• One asynchronous UART

The S3F84A5 microcontroller is ideal for use in a wide range of home applications and motor controller (especially for E-bike) requiring simple timer/counter, ADC, PWM etc. They are currently available in 28-pin SOP and 32-pin ELP package.
