Description: CH347是一款高速USB总线转接芯片，通过USB总线提供异步串口、I2C同步串行接口、SPI同步串行接口和JTAG接口等。
在异步串口方式下，CH347提供了2个高速串口，支持RS485串口收发使能控制、硬件流控和常用的MODEM联络信号，用于为计算机扩展异步串口，或者将普通的串口设备或者MCU直接升级到USB总线。
在同步串行接口方式下，CH347提供了1个2线I2C接口(SCL线、SDA线)和1个4线SPI接口(SCS线、SCK/CLK线、MISO/SDI/DIN线、MOSI/SDO/DOUT线)，用于为计算机扩展2线或4线同步串行接口，操作EEPROM、FLASH和传感器等器件。

Description: General Description
The SC14480A5M, SC14480A2M6 are family members
of digital CMOS ICs with fully integrated radio
transceivers and baseband processors for DECT &
DECT 6.0 CAT-iQ handsets and basestations.
The SC14480A5M has a FLASH version with CR16
trace unit for development of all family members.
For the family overview refer to SiTel Portal
SC1448x_product_overview.xls
The radio transceiver, when combined with a power
amplifier and a Tx/Rx switch, implements a complete
DECT radio transceiver compiant with the ETSI CTR6
standard.
The audio path comprises a 16 bit CODEC, analog
frontend, including a high efficiency 4 Ohm audio
amplifier (Class-D) and user programmable Gen2DSP.
The CompactRISCTM CR16Cplus microprocessor with
a one wire debug port running from ROM controls the
protocol stack and the I/O peripherals, keyboard,
UART, ACCESS bus, SPI, LED drivers, RF switches
