1 / 429 page  2003.10.15 Preliminary product information describes products that are in development, for which full characterization data and associated errata are not yet available Specifications and information herein are subject to change without notice. S3C2440X RISC MICROPROCESSOR PRODUCT OVERVIEW 1-1 PRODUCT OVERVIEW INTRODUCTION This manual describes SAMSUNG's S3C2440X 16/32-bit RISC microprocessor. SAMSUNG’s S3C24440X is designed to provide hand-held devices and general applications with low-power, and high-performance micro- controller solution in small die size. To reduce total system cost, the S3C2440X includes the following components separate 16KB Instruction and 16KB Data Cache, MMU to handle virtual memory management, LCD Controller (STN & TFT), NAND Flash Boot Loader, System Manager (chip select logic and SDRAM Controller), 3-ch UART, 4-ch DMA, 4-ch Timers with PWM, I/O Ports, RTC, 8-ch 10-bit ADC and Touch Screen Interface, Camera interface, IIC-BUS Interface, IIS-BUS Interface, USB Host, USB Device, SD Host & Multi-Media Card Interface, 2- ch SPI and PLL for clock generation. The S3C2440X has been developed using an ARM920T core, 0.13um CMOS standard cells and a memory complier. Its low-power, simple, elegant and fully static design is particularly suitable for cost- and power-sensitive applications. It adopts a new bus architecture known as Advanced Micro controller Bus Architecture (AMBA). The S3C2440X offers outstanding features with 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 an 8-word line length. By providing a complete set of common system peripherals, the S3C2440X minimizes overall system costs and eliminates the need to configure additional components. The integrated on-chip functions that are described in this document include: • 1.2V internal, 1.8V/2.5V/3.3V memory, 3.3V external I/O microprocessor with 16KB I-Cache/16KB D- Cache/MMU • External memory controller (SDRAM Control and Chip Select logic) • LCD controller (up to 4K color STN and 256K color TFT) with 1-ch LCD-dedicated DMA • 4-ch DMAs with external request pins • 3-ch UART (IrDA1.0, 64-Byte Tx FIFO, and 64-Byte Rx FIFO) / 2-ch SPI • 1-ch multi-master IIC-BUS/1-ch IIS-BUS controller • SD Host interface version 1.0 & Multi-Media Card Protocol version 2.11 compatible • 2-port USB Host /1- port USB Device (ver 1.1) • 4-ch PWM timers & 1-ch internal timer • Watch Dog Timer • 130-bit general purpose I/O ports / 24-ch external interrupt source • Power control: Normal, Slow, Idle and Sleep mode • 8-ch 10-bit ADC and Touch screen interface • RTC with calendar function • On-chip clock generator with PLL |
