PRODUCT OVERVIEW

SAM8 PRODUCT FAMILY

Samsung's SAM8 family of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU with a wide

range of integrated peripherals, in various mask-programmable ROM sizes. Analog its 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

The 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.

S3C8625/C8627/C8629/P8629 MICROCONTROLLERS

S3C8625/C8627/C8629/P8629 single-chip 8-bit

microcontrollers are based on the powerful SAM8

CPU architecture. The internal register file is logically

expanded to increase the on-chip register space.

S3C8625/C8627/C8629/P8629 contain 16/32 K bytes

of on-chip program ROM.

In line with Samsung's modular design approach, the

following peripherals are integrated with the SAM8

core:

— Four programmable I/O ports (total 27 pins)

— One 8-bit basic timer for oscillation stabilization

and watchdog functions

— One 8-bit general-purpose timer/counter with

selectable clock sources

— One 12-bit counter with selectable clock sources,

including Hsync or Csync input

— One interval timer

— PWM block with seven 8-bit PWM circuits

— Sync processor block (for Vsync and Hsync I/O,

Csync input, and Clamp signal output)

— DDC and normal Multi-master IIC-bus

— 4-channel A/D converter (8-bit resolution)

S3C8625/C8627/C8629/P8629 are a versatile

microcontrollers which are ideal for use in multi-sync

monitors or in general-purpose applications that

require sophisticated timer/counter, PWM, sync

signal processing, A/D converter, and multi-master

IIC-bus support with DDC. They are available in a 42-

pin SDIP or a 44-pin QFP package.

OTP

S3C8625/C8627/C8629 microcontrollers are also available in OTP (One Time Programmable) version named,

S3P8629. S3P8629 microcontroller has an on-chip 32-Kbyte one-time-programmable EPROM instead of masked

ROM. S3P8629 is comparable to S3C8625/C8627/C8629, both in function and pin configuration except its ROM

size.
