PRODUCT OVERVIEW
1 PRODUCT OVERVIEW
SAM8 PRODUCT FAMILY
Samsung's new SAM8 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.
A dual address/data bus architecture and a large number of bit- or nibble-configurable I/O ports provide a flexible
programming environment for applications with varied memory and I/O requirements.
Timer/counters with selectable operating modes are included to support real-time operations. Many SAM8
microcontrollers have an external interface that provides access to external memory and other peripheral
devices.
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 six CPU clocks) can be assigned to
specific interrupt levels.
S3C8444 MICROCONTROLLER
The S3C8444 single-chip microcontroller is fabricated using a highly advanced CMOS process. Its design is
based on the powerful SAM8 CPU core. Stop and Idle power-down modes were implemented to reduce power
consumption. The size of the internal register file is logically expanded, increasing the addressable on-chip
register space to 1040 bytes. A flexible yet sophisticated external interface is used to access up to 64-Kbytes of
program and data memory. The S3C8444 is a versatile microcontroller that is ideal for use in a wide range of
general-purpose applications such as CD-ROM/DVD-ROM drives.
Using the SAM8 modular design approach, the following peripherals were integrated with the SAM8 CPU core:
