This manual describes SAMSUNG's S3C2410X 16/32-bit RISC microprocessor. This product is designed to
provide hand-held devices and general applications with cost-effective, low-power, and high-performance microcontroller
solution in small die size. To reduce total system cost, the S3C2410X 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, 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 S3C2410X 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- and power-sensitive
applications. It adopts a new bus architecture called Advanced Microcontroller Bus Architecture (AMBA).
The S3C2410X 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 S3C2410X 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 int., 3.3V memory, 3.3V external I/O microprocessor with 16KB I-Cache/16KB D-Cache/MMU
