PRODUCT OVERVIEW

S3C8-SERIES MICROCONTROLLES

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

— 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 six CPU clocks) can be assigned to specific interrupt levels.


S3C821A/P821A MICROCONTROLLER

The S3C821A/P821A single-chip CMOS microcontroller is fabricated using the highly advanced CMOS process, based on Samsung’s newest CPU architecture.

The S3C821A is a microcontroller with a 48-Kbyte mask-programmable ROM embedded.

The S3P821A is a microcontroller with a 48-Kbyte one-time-programmable ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C821A/P821A by integrating the following peripheral modules with the powerful SAM8 core:


— Six programmable I/O ports, including five 8-bit ports and one 7-bit port, for a total of 47 pins.

— Twelve bit-programmable pins for external interrupts.

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

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

— Watch timer for real time.

— 4-input A/D converter

— Serial I/O interface

The S3C821A/P821A is versatile microcontroller for cordless phone, pager, etc. They are currently available in 80-pin TQFP and 80-pin QFP package.
