STM32G0 The world's first USB-CTM & Power Delivery 3.0 MCU

Why use USB-CTM and Power Delivery technology ?

USB Type-CTM connectors enhance the user experience

? It's a 24-pin miniature and reversible connector. USB-C plug is the same on both sides ? Some pins can be repurposed to support proprietary protocols (Alternate Modes) ? Able to transmit 15W of power natively without USB PD protocol

To exchange more data faster with various protocols

? 2 separate USB data paths are available simultaneously: USB 2.0 + USB 3.1 (up to 10 Gbit/s) ? Display Port, HDMI, MHL, Thunderbolt are supported to carry video/audio signals ? Conventional I?C/SPI/UART/Ethernet interfaces can be "bridge" to USB-C

To get more power with a comprehensive and robust protocol

? USB Power Delivery protocol enables power negotiation (up to 100 W) ? Able to discover power capabilities and needs between two USB-CTM connected devices ? 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

? Identify genuine chargers or accessories using USB PD authentication messages ? USB PD Alternate Modes and Vendor Defined Messages enable product differentiation. ? Secure firmware upgrade capability

USB Power Delivery is a protocol!

To safely enhance user experience through innovation

To get more power in a robust and safe way! ? Enables advanced and higher voltage and current negotiation

(up to 100 W) ? Source and Sink establish power contracts that match their

power capabilities and needs (ex: technology of battery used, power budget allocation, number of ports, etc.) ? Supply voltage (Vbus) is fixed (5V, 9V, 15V, or 20V) or configurable (Programming Power Supply) ? Dual Role Power devices can swap power direction (ex: using a tablet to charge a notebook!)

To extend devices functionalities and create an unique differentiation ! ? Use of USB PD Structured Vendor Defined Messages (VDMs)

to extend functionalities (video output, authentication, etc.)
