PRODUCT OVERVIEW

1 PRODUCT OVERVIEW

SAM87 PRODUCT FAMILY

Samsung's SAM87 family 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. Important CPU features include:

â Efficient register-oriented architecture

â Selectable CPU clock sources

â Release of Idle and Stop power-down modes by interrupt

â Built-in basic timer circuit 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.

S3C8847/C8849/P8849 MICROCONTROLLERS

The S3C8847 microcontroller has a 24-Kbyte on-chip program memory and the S3C8849 has a 32-Kbyte. Both

chips have a 272-byte general-purpose internal register file. The interrupt structure has nine interrupt sources

with nine interrupt vectors. The CPU recognizes seven interrupt priority levels.

Using a modular design approach, the following peripherals were integrated with the SAM87 core to make the

S3C8847/C8849/P8849 microcontrollers suitable for use in color television and other types of screen display

applications:

â Four programmable I/O ports (26 pins total: 16 general-purpose I/O pins; 10 n-channel, open-drain

output pins)

â 4-bit resolution A/D converter (4 channels)

â 14-bit PWM output (Two channels: push-pull type, open-drain type)

â Basic timer (BT) with watchdog timer function

â One 8-bit timer/counter (T0) with interval timer and PWM mode

â One 8-bit general-purpose timer/counter (TA) with prescalers

â On-screen display (OSD) with a wide range of programmable features, including halftone control

signal output

The S3C8847 and the S3C8849 are available in versatile 42-pin SDIP package.

OTP

The S3C8847/C8849 microcontrollers are also available in OTP (One Time Programmable) version, named the

S3P8849. The S3P8849 microcontroller has an on-chip 32-Kbyte one-time-programmable EPROM instead of a

masked ROM. The KS88P8432 is comparable to the S3C8847/C8849, both in function and pin configuration.
