SC6820 Device Specification
1 System Overview
SC6820 is a GSM/GPRS/EDGE baseband (BB) chip for mobile devices, and it also
integrated a lot of multimedia accelerators and 3D graphic engine to develop rich
multimedia applications. This document specifies the functions and features of SC6820.
1.1 General Description
SC6820 is a highly integrated mixed signal baseband processor for
GSM/GPRS/EDGE applications. It consists with support of specially optimized
architecture and many dedicate accelerators. SC6820 can achieve high performance
and low power for a lot of applications. Proprietary architectures and algorithms were
developed for low power ASIC design and power management. Unique techniques
are used for noise/offset calibration and cancellation. Overall, SC6820 presents a
revolutionary platform for mobile devices.
Platform
SC6820 is capable of running the ARM® Cortex A5TM 32-bit RISC processor at up to
1GHz, thus providing fast data processing capabilities. The high clock frequency,
separate code and data caches are included to improve the overall system efficiency.
For large amount of data transfer, high performance DMA（Direct Memory Access）
with hardware flow control is implemented, which greatly enhance the data movement
efficiency with reducing MCU and DSP processing load.
Targeted as a high performance platform for mobile applications, Unique ID（UID）and
secure boot are also provided to prevent unauthorized porting of the software load
and fulfill other applications.
External Memory
SC6820 supports mobile DDR/SDR-SDRAM, Nand flash. The external memory
interface is designed for 1.8V I/O voltage. The driving strength is configurable for
signal integrity adjustment.
Multi-media
SC6820 integrated digital still camera processor, H.264 decoder and
MPEG4/H.263/JPEG codec engines. The multi-media subsystem provides a
connection to up to 2 CMOS image sensors. With its high performance application
platform.
SC6820 utilizes high resolution DAC, digital audio, and audio synthesis technology to
provide superior audio features for all future multi-media needs.
Furthermore, a dedicated LCDC controller enables MCU interface to 8/9/16/18/24 bit
LCM panels, which provides much better configurability for multi-media products.
Peripherals and connectivity interface
SC6820 incorporates myriads of advanced peripherals for different applications. It
supports 3 UART, 2 IIS/PCM, 2 SPI, Keypad controller, 2 SIM controller, 4 PWM, 4
I2C, USB2.0, 2 SDIO, Touch Panel controller, and General Purpose Programmable
I/Os(GPIO). These interfaces provide SC6820 users with the highest degree of
flexibility in implementing solutions suitable for the targeted application.
