Samsung S3F80JB Benutzerhandbuch

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.  

The S3F80JB single-chip CMOS microcontroller is fabricated using a highly advanced CMOS process and is 
based on Samsung's newest CPU architecture.  

The S3F80JB is the microcontroller which has 64-Kbyte Flash Memory ROM. 

Using a proven modular design approach, Samsung engineers developed S3F80JB by integrating the following 
peripheral modules with the powerful SAM8 RC core: 

—  Internal LVD circuit and 16 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. 

—  4-bit analog voltage comparator with four/three channels (internal/external reference). 

—  One 8-bit counter with auto-reload function and one-shot or repeat control. 

The S3F80JB is a versatile general-purpose microcontroller, which is especially suitable for use as remote 
transmitter controller. It is currently available in a 32-pin SOP and 44-pin QFP package.
