1 PRODUCT OVERVIEW
S3C8/S3F8-SERIES MICROCONTROLLERS
Samsung's S3C8/S3F8-series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide
range of integrated peripherals, and various flash memory ROM sizes. Important CPU features include:
• Efficient register-oriented architecture
• Selectable CPU clock sources
• Idle and Stop power-down mode release by interrupts
• 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 four CPU clocks) can be assigned to
specific interrupt levels.
S3F80P5 MICROCONTROLLER
The S3F80P5 single-chip CMOS microcontroller is fabricated using a highly advanced CMOS process and is
based on Samsung's newest CPU architecture.
The S3F80P5 is the microcontroller which has 18-Kbyte Flash Memory ROM.
Using a proven modular design approach, Samsung engineers developed S3F80P5 by integrating the following
peripheral modules with the powerful SAM8 RC core:
• Internal LVD circuit and 9 bit-programmable pins for external interrupts.
• One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
• One 8-bit Timer/counter with three operating modes.
• Two 16-bit timer/counters with selectable operating modes.
• One 8-bit counter with auto-reload function and one-shot or repeat control.
The S3F80P5 is a versatile general-purpose microcontroller, which is especially suitable for use as remote
transmitter controller. It is currently available in a 24-pin SOP/SDIP package.
