PRODUCT OVERVIEW

S3C8-SERIES MICROCONTROLLERS

Samsungs S3C8 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. Among the major CPU features are:

— Efficient register-oriented architecture

— Selectable CPU clock sources

— Idle and Stop power-down mode release by interrupt or reset

— 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.

S3C8275/F8275/C8278/F8278/C8274/F8274 MICROCONTROLLER

The S3C8275/F8275/C8278/F8278/C8274/F8274 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process, based on Samsungs latest CPU architecture.

The S3C8275/C8278/C8274 is a microcontroller with a 16/8/4K-byte mask-programmable ROM embedded.

The S3F8275/F8278/F8274 is a microcontroller with a 16/8/4K-byte flash ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C8275/F8275/C8278/F8278/C8274/F8274 by integrating the following peripheral modules with the powerful SAM8 core:

— Seven programmable I/O ports, including six 8-bit ports and one 4-bit port, for a total of 52 pins.

— Eight bit-programmable pins for external interrupts.

— One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).

— Two 8-bit timer/counter with selectable operating modes.

— Watch timer for real time
