PRODUCT OVERVIEW

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. 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 four CPU clocks) can be assigned

to specific interrupt levels.

S3C831B MICROCONTROLLER

The S3C831B single-chip microcontroller are fabricated using the highly advanced CMOS process. Its design is

based on the powerful SAM88RC CPU core. Stop and idle (power-down) modes were implemented to reduce

power consumption.

The S3C831B is a microcontroller with a 64K-byte mask-programmable ROM embedded.

The S3P831B is a microcontroller with a 64K-byte one-time-programmable ROM embedded.

Using the SAM88RC modular design approach, the following peripherals were integrated with the SAM88RC

CPU core:

— Large number of programable I/O ports (Total 72 pins)

— PLL frequency synthesizer

— 16-bits intermediate frequency counter

— Two synchronous SIO modules

— Two 8-bit timer/counters

— One 16-bit timer/counter

— Low voltage reset

— A/D converter with 8 selectable input pins

OTP

The S3C831B microcontroller is also available in OTP (One Time Programmable) version, S3P831B.

The S3P831B microcontroller has an on-chip 64K-byte one-time-programmable EPROM instead of masked

ROM. The S3P831B is comparable to S3C831B, both in function and in pin configuration.
