1 PRODUCT OVERVIEW

S3C8-SERIES MICROCONTROLLERS

Samsung's 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. The major CPU features are:

—Efficient register-oriented architecture

—Selectable CPU clock sources

—Idle and Stop power-down mode released 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.

S3C84E5/C84E9/P84E9 MICROCONTROLLER

The S3C84E5/C84E9/P84E9 single-chip CMOS microcontrollers are fabricated using the highly advanced CMOS process technology based on Samsung’s latest CPU architecture.

The S3C84E5 is a microcontroller with a 16K-byte mask-programmable ROM embedded.

The S3C84E9 is a microcontroller with a 32K-byte mask-programmable ROM embedded.

The S3P84E9 is a microcontroller with a 32K-byte OTP ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C84E5/C84E9/P84E9 by integrating the following peripheral modules with the powerful SAM8 core:

—Five programmable I/O ports (42SDIP: 34pins, 44QFP: 36pins)

—Eleven bit-programmable pins for external interrupts.

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

—Two 8-bit timer/counter and Two 16-bit timer/counter with selectable operating modes.

—One asynchronous UART

—10-bit 8-channel A/D converter

The S3C84E5/C84E9/P84E9 is versatile microcontroller for home appliances and ADC applications, etc. They are currently available in 44-pin QFP and 42-pin SDIP package.
