1 STM32G0 World s 1st TM & Power Delivery 3.0 MCU

2 Why to use and Power Delivery Technology? 2 USB Type-C connector enhances user experience It s a 24-pin miniature and reversible connector. cable has same plug as both ends Some pins can be repurposed to support proprietary protocols (Alternate Modes) 15W of power can transit natively without USB PD protocol To exchange more data faster with various protocols 2 separates USB data paths are available simultaneously : USB USB 3.1 (up to 10Gbit/s) Display Port, HDMI, MHL, Thunderbolt are supported to carry video/audio signals Conventional I²C/SPI/UART/Ethernet interfaces can be bridge to To get more power with a comprehensive and robust protocol USB Power Delivery protocol enables power negotiation (up to 100W) It allows to discover power capabilities and needs between two connected devices.it enables advanced voltage and current negotiation to support fast charging USB PD is used to activate Alternate Modes or to carry Authentication messages To protect your application and extend its functionalities Identification of genuine chargers or accessories using USB PD authentication messages USB PD Alternate Modes and Vendor Defined Messages enable product differentiation. Secure firmware upgrade capability

3 USB Power Delivery is a Protocol! 3 To enhance user experience safety thru innovation To get more power in a robust and safe way! Enables advanced and higher voltage and current negotiation (up to 100W) Source and Sink establish power contracts that match with their power capabilities and needs (ex : technology of battery used, power budget allocation, number of ports etc) Supply voltage (V bus ) is fixed (5V,9V,15V,20V) or configurable (Programming Power Supply) Dual Role Power devices can swapped power direction (ex : tablet charging a Notebook!) Mode of operation Nominal voltage Maximum current Maximum power USB PD Configurable 5 A 100 W USB Type-C 3.0 A 5 V 3.0 A 15 W USB Type-C 1.5 A 5 V 1.5 A 7.5 W USB BC V Up to 1.5 A 7.5 W To extend devices functionalities and create an unique differentiation! Use of USB PD Structured Vendor Defined Messages (VDMs) to extend the functionality a device exposes Default USB Power USB V 900 ma (x1) 1,500 ma (x2) 4.5 W 7.5 W USB V 500mA 2.5 W
