Preface

The S3C8245/P8245/C8249/P8249 Microcontroller User's Manual is designed for application designers and programmers who are using the S3C8245/P8245/C8249/P8249 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 S3C8245/P8245/C8249/P8249 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 S3C8245/P8245/C8249/P8249 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 S3C8245/P8245/C8249/P8249 microcontroller. Also included in Part II are electrical, mechanical, OTP, and development tools data. It has 16 chapters:

Chapter 7 Clock Circuit Chapter 8 nRESET and Power-Down Chapter 9 I/O Ports Chapter 10 Basic Timer Chapter 11 8-bit Timer A/B Chapter 12 16-bit Timer 0/1 Chapter 13 Watch Timer Chapter 14 LCD Controller/Driver

Two order forms are included at the back of this manual to facilitate customer order for S3C8245/P8245/ C8249/P8249 microcontrollers: the Mask ROM Order Form, and the Mask Option Selection Form. You can photocopy these forms, fill them out, and then forward them to your local Samsung Sales Representative.

S3C8245/P8245/C8249/P8249 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 — 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.

S3C8245/P8245/C8249/P8249 MICROCONTROLLER

The S3C8245/P8245/C8249/P8249 single-chip CMOS microcontroller are fabricated using the highly advanced CMOS process, based on Samsung’s newest CPU architecture.

The S3C8245, S3C8249 are a microcontroller with a 16K-byte, 32K-byte mask-programmable ROM embedded respectively.

The S3P8245 is a microcontroller with a 16K-byte one-time-programmable ROM embedded. The S3P8249 is a microcontroller with a 32K-byte one-time-programmable ROM embedded.

Using a proven modular design approach, Samsung engineers have successfully developed the S3C8245/P8245/C8249/P8249 by integrating the following peripheral modules with the powerful SAM8 core:

— Six programmable I/O ports, including five 8-bit

ports and one 5-bit port, for a total of 45 pins.

— Eight bit-programmable pins for external

interrupts.

— One 8-bit basic timer for oscillation stabilization

and watchdog functions (system reset).

— Two 8-bit timer/counter and two 16-bit

timer/counter with selectable operating modes. — Watch timer for real time. — 8-input A/D converter — Serial I/O interface The S3C8245/P8245/C8249/P8249 is versatile

microcontroller for camera, LCD and ADC application, etc. They are currently available in 80-pin TQFP and 80-pin QFP package

OTP

The S3P8245/P8249 are OTP (One Time Programmable) version of the S3C8245/C8249 microcontroller. The S3P8245 microcontroller has an on-chip 16K-byte one-time-programmable EPROM instead of a masked ROM. The S3P8249 microcontroller has an on-chip 32K-byte one-time-programmable EPROM instead of a masked ROM. The S3P8245 is comparable to the S3P8245, both in function and in pin configuration. The S3P8249 is comparable to the S3P8249, both in function and in pin configuration.
