S3F8-SERIES MICROCONTROLLERS
Samsung's S3F8 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. Important CPU features include:

- Efficient register-oriented architecture
- Selectable CPU clock sources
- Idle and Stop power-down mode release by interrupt
- 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.

S3F84K4 MICROCONTROLLER
The S3F84K4 single-chip CMOS micro-controller is fabricated using a highly advanced CMOS process and is based on Samsung's newest CPU architecture. Its design is based on the powerful SAM8RC CPU core. Stop and idle (power-down) modes were implemented to reduce power consumption.

The S3F84K4 is a micro-controller with a 4k-byte multi-time-programmable Flash ROM embedded.

Using the SAM8RC design approach, the following peripherals were integrated with the SAM8RC core:

- Three configurable I/O ports (17 pins)
- Five interrupt sources with five vectors and three interrupt levels
- A 16-bit timer 0 with one 16-bit timer or two 8-bit timers mode.
- Analog to digital converter with nine input channels (MAX) and 10-bit resolution
- One 12-bit PWM output

The S3F84K4 microcontroller is ideal for use in a wide range of electronic applications requiring simple timer/counter, PWM, ADC. S3F84K4 is available in a 20/16-pin DIP and a 20/16-pin SOP and a 20/16-pin SSOP package.
