没有：下面的文字是datasheet中的s3c2440的特点介绍

The S3C2440A 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 S3C2440A minimizes overall system costs and
eliminates the need to configure additional components. The integrated on-chip functions that are described in this
document include:
·  Around 1.2V internal, 1.8V/2.5V/3.3V memory, 3.3V external I/O microprocessor with 16KB I-Cache/16KB DCache/
MMU
·  External memory controller (SDRAM Control and Chip Select logic)
·  LCD controller (up to 4K color STN and 256K color TFT) with LCD-dedicated DMA
·  4-ch DMA controllers with external request pins
·  3-ch UARTs (IrDA1.0, 64-Byte Tx FIFO, and 64-Byte Rx FIFO)
·  2-ch SPls
·  IIC bus interface (multi-master support)
·  IIS Audio CODEC interface
·  AC’97 CODEC interface
·  SD Host interface version 1.0 & MMC Protocol version 2.11 compatible
·  2-ch USB Host controller / 1-ch USB Device controller (ver 1.1)
·  4-ch PWM timers / 1-ch Internal timer / Watch Dog Timer
·  8-ch 10-bit ADC and Touch screen interface
·  RTC with calendar function
·  Camera interface (Max. 4096 x 4096 pixels input support. 2048 x 2048 pixel input support for scaling)
·  130 General Purpose I/O ports / 24-ch external interrupt source
·  Power control: Normal, Slow, Idle and Sleep mode
·  On-chip clock generator with PLL
