Product Descriptions

RK2918 is a low power, high performance processor solution for mobile phones, personal mobile internet device and other digital multimedia applications.

RK2918 integrates an ARM Cortex-A8 with one NEON coprocessor. Many embedded powerful hardware accelerators provide optimized hardware performance for high-end application. RK2918 supports almost full-format video decoder by 1080p@30fps such as H264, H263, RMVB, MPEG2, MPEG4, VC1, AVS, VP8 etc. Also supports H.264 encoder by 1080P@30fps, high-quality JPEG encoder/decoder and special image preprocessor and postprocessor.

Embedded 2D/3D hardware engine makes RK2918 completely compatible with OpenGL ES2.0, OpenGL ES1.1 and OpenVG graphics standards.

RK2918 has high-performance external memory interface (DDRIII/DDRII/LPDDR) capable of sustaining demanding memory bandwidths, also provides a complete set of peripheral interface to support very flexible applications as follows:

•  2 banks, 8bits/16bits Nor Flash/SRAM interface

•  8 banks, 8bits/16bits Async NAND FLASH, LBA NANDN Flash, 8bits sync ONFI NAND Flash, all embedded 24bits HW ECC

•  2 ranks, 2GB Memory space, 16bits/32bits DDRIII,DDRII-800,LPDDR-400

•  8bits HS-MMC/SD, 4bits SDIO, 8bits eMMC interface

•  24bits high-performance, 3-layers TFT LCD Controller with post-processor, 1920x1080 maximum display size

•  eBook display interface with 2048x2048 maximum resolution

•  8bits sensor/CCIR656 interface and 10bits/12bits Raw data interface

•  2ch I2S interface, 8ch I2S interface, PCM/SPDIF interface

•  USB OTG 2.0/USB Host2.0/ USB Host 1.0

•  RMII/MII interface

•  High-speed ADC interface, TS stream interface

•  8bits/16bits async modem interface

•  4x I2C, 4xUART with hardware flow-control , 2x SPI , PWM

This document will provide guideline on how to use RK2918 correctly and efficiently. In them, the chapter 1 and chapter 2 will introduce the features, block diagram, and signal descriptions and system usage of RK2918, the chapter 3 through chapter 46 will describe the full function of each module in detail.
