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
(S3F8278/F8274).
5. The chip erasing is available in Tool Program Mode o nly.
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 S3F8275.
Preface
The S3C8275/F8275/C8278/F8278/C8274/F8274
Microcontroller User's Manual
is designed for application designers
and programmers who are using the S3C8275/F8275/C8278/F8278/C8274/F8274 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
Chapter 2
Chapter 3
Product Overview
Address Spaces
Addressing Modes
Chapter 4
Chapter 5
Chapter 6
Control Registers
Interrupt Structure
Instruction Set
Chapter 1, "Product Overview," is a high-level introduction to S3C8275/F8275/C8278/F8278/C8274/F8274 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 S3C8275/F8275/C8278/F8278/C8274/F8274 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
S3C8275/F8275/C8278/F8278/C8274/F8274 microcontroller. Also included in Part II are electrical, mechanical, Flash
MCU, and development tools data. It has 14 chapters:
