PRODUCT OVERVIEW

INTRODUCTION

SAMSUNGs S3C2400 16/32-bit RISC microprocessor is designed to provide a cost-effective, low power, small die size and high performance micro-controller solution for hand-held devices and general applications. To reduce total system cost, S3C2400 also provides the following: separate 16KB Instruction and 16KB Data Cache, MMU to handle virtual memory management, LCD controller (STN & TFT), 2-channel UART with handshake, 4-channel DMA, System Manager (chip select logic, EDO/SDRAM controller), 4-channel Timers with PWM, I/O Ports, RTC, 8-channel 10-bit ADC, IIC-BUS interface, IIS-BUS interface, USB Host, USB Device, Multi-Media Card Interface, SPI and PLL for clock generation.

The S3C2400 was developed using an ARM920T core, 0.18um CMOS standard cells and a memory complier. Its low-power, simple, elegant and fully static design is particularly suitable for cost-sensitive and power sensitive applications. Also S3C2400 adopts a new bus architecture, AMBA (Advanced Microcontroller Bus Architecture) An outstanding feature of the S3C2400 is its CPU core, a 16/32-bit ARM920T RISC processor designed by Advanced RISC Machines, Ltd. The ARM920T implements MMU, AMBA BUS, and Harvard cache architecture with separate 16KB instruction and 16KB data caches, each with a 8-word line length.

By providing complete set of common system peripherals, the S3C2400 minimizes overall system costs and eliminates the need to configure additional components. The integrated on-chip functions that are described in this document include:

? 1.8V internal, 3.3V external (I/O boundary) microprocessor with 16KB I-Cache,
