NOTES:
1.The programming time is the time during which one byte (8-bit) is programmed.
2.The chip erasing time is the time during which all 16K byte block is erased.
3.The sector erasing time is the time during which all 128 byte block is erased.
4.Maximum number of writing/erasing is 10,000 times for full-flash(S3F8275) and 100 times for half-flash (S3F8278X/F8274X).
5.The chip erasing is available in Tool Program Mode only.
2. Condition of Operating Voltage
Condition of operating voltage is modified “fx = 0 − 4.2MHz” to “fx = 0.4 − 4.2MHz” at 2.0V – 3.6V and “fx = 0 − 8MHz” to “fx = 0.4 − 8MHz” at 2.5V − 3.6V in the page 17-2.
3. CHAPTHER 16. Embedded Flash Memory Interface
This chapter is modified for only S3F8275X.
4. CHAPTHER 7. Clock Circuit
The contents of OSCCON.7 should be changed “ 0 = Select normal circuit for sub oscillator” into “ 0 = Initial state” in the page 4-21 and Figure 7-10.
It is added “NOTE: The OSCCON.7 should be maintained to “1”, during the sub oscillator operation.” In the page 4-21 and Figure 7-10.
The figure 7-7 is modified partly.
Descriptions of Revision 1.4
1. Smart Option Area
The Figures are modified about smart option area. Those are “Figure 2-1. Program Memory Address Space” and “Figure 5-3. ROM Vector Address Area”.
2. CHAPTHER 17. Electrical Data
It is changed “VDD = 2.0 V to 3.6 V” into “VDD = 2.2 V to 3.6 V” in the Table 17-12.
3. DEVICE NAME
The device name is changed S3C8275/F8275/C8278/F8278/C8274/F8274 to S3C8275X/F8275X/C8278X/F8278X/C8274X/F8274X. The ‘X’ means ‘Commercial type’.
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 4 |
Control Registers |
Chapter 2 |
Address Spaces |
Chapter 5 |
Interrupt Structure |
Chapter 3 |
Addressing Modes |
Chapter 6 |
Instruction Set |
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.
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:

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.
