UPD300 SoC chip target at newest USB interface solution which integrate both Type-C interface controller and Power Delivery controller. The chip fully meets the relevant spec. within the USB 3.1 standard set defined by the USB_IF.
The UPD300 SoC chip provides a flexible programmable architecture that allows for continuous firmware upgrading to meet future standard updates. It integrates all necessary digital logic and analog circuits to achieve the Type-C interface detection and control, power delivery packet BMC Encoding/Decoding in PHY layer, and PD packet Transmit/Receive state control in protocol layer. It also integrates a high performance MCU core to implement the upper device policy management and the system configuration management. By using this architecture, UPD300 can achieve a complete PD/Type-C system, including the SRC/SNK/DRP interface mode control management and the corresponding PD message interaction. UPD300 also provides the necessary external communication interface to support interaction with higher level systems.
UPD300 SoC chip also integrate more system level function module, reduces board BOM material requirement. Combined with the flexible customized firmware, customer can easily deploy the USB PD/Type-C system in various system products, greatly shorten the development cycle and cost.
