Preface
The S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X Microcontroller User's Manual is designed for
application designers and programmers who are using the S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X
microcontroller for application development. It is organized in two main parts:
Part I Programming Model Part II Hardware Descriptions
Part I contains software-related information to familiarize you with the microcontroller's architecture, programming
model, instruction set, and interrupt structure. It has six chapters:
Chapter 1 Product Overview
Chapter 2 Address Spaces
Chapter 3 Addressing Modes
Chapter 1, "Product Overview," is a high-level introduction to
S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X with general product descriptions, as well as detailed
information about individual pin characteristics and pin circuit types.
Chapter 2, "Address Spaces," describes program and data memory spaces, the internal register file, and register
addressing. Chapter 2 also describes working register addressing, as well as system stack and user-defined
stack operations.
Chapter 3, "Addressing Modes," contains detailed descriptions of the addressing modes that are supported by the
S3C8-series CPU.
Chapter 4, "Control Registers," contains overview tables for all mapped system and peripheral control register
values, as well as detailed one-page descriptions in a standardized format. You can use these easy-to-read,
alphabetically organized, register descriptions as a quick-reference source when writing programs.
Chapter 5, "Interrupt Structure," describes the S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X interrupt
structure in detail and further prepares you for additional information presented in the individual hardware module
descriptions in Part II.
Chapter 6, "Instruction Set," describes the features and conventions of the instruction set used for all S3C8-series
microcontrollers. Several summary tables are presented for orientation and reference. Detailed descriptions of
each instruction are presented in a standard format. Each instruction description includes one or more practical
examples of how to use the instruction when writing an application program.
A basic familiarity with the information in Part I will help you to understand the hardware module descriptions in
Part II. If you are not yet familiar with the S3C8-series microcontroller family and are reading this manual for the
first time, we recommend that you first read Chapters 1–3 carefully. Then, briefly look over the detailed
information in Chapters 4, 5, and 6. Later, you can reference the information in Part I as necessary.
Chapter 4 Control Registers
Chapter 5 Interrupt Structure
Chapter 6 Instruction Set
Part II "hardware Descriptions," has detailed information about specific hardware components of the
S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X microcontroller. Also included in Part II are electrical,
mechanical, Flash MCU, and development tools data. It has 14 chapters:
Chapter 7 Clock Circuit
Chapter 8 RESET and Power-Down

S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X 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 or reset
• 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.
S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X MICROCONTROLLER
The S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X single-chip CMOS microcontrollers are fabricated
using the highly advanced CMOS process, based on Samsung's latest CPU architecture.
The S3C8275X/C8278X/C8274X is a microcontroller with a 16/8/4K-byte mask-programmable ROM embedded.
The S3F8275X/F8278X/F8274X is a microcontroller with a 16/8/4K-byte flash ROM embedded.
Using a proven modular design approach, Samsung engineers have successfully developed the
S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X by integrating the following peripheral modules with the
powerful SAM8 core:
• Seven programmable I/O ports, including six 8-bit ports and one 4-bit port, for a total of 52 pins.
• Eight bit-programmable pins for external interrupts.
• One 8-bit basic timer for oscillation stabilization and watchdog function (system reset).
• Two 8-bit timer/counter with selectable operating modes.
• Watch timer for real time
FLASH
The S3F8275X/F8278X/F8274X are FLASH version of the S3C8275X/C8278X/C8274X microcontroller. The
S3F8275X/F8278X/F8274X microcontroller has an on-chip FLASH ROM instead of a masked ROM. The
S3F8275X/F8278X/F8274X is comparable to the S3C8275X/C8278X/C8274X, both in function and in pin
configuration. The S3F8275X only is a full flash. The full flash means that data can be written into the program
ROM by an instruction.
