SJYN1622A MOTO MODS

MDK User Guide: Reference Moto Mod Part number: SJYN1622A Overview The Reference Moto Mod is the central component for the creation of your prototypes. It provides the core interfaces to the Moto Z platform, processing resources, GPIO and standard periphe ral interfaces, power and charging control, and the capability to configure these blocks appropriately for your project. Key Components and Configuration The Moto Mod Micro Controller (MuC) The MuC is the target for custom firmware for your Moto Mod. Powered by a Cortex-M4 based STML476, it provides onboard compute and control, GPIO, and various standard interfaces used to realize your project. The MuC is the main point of communication between the Moto Z and includes Greybus abstraction layer. Moto High Speed Bridge (Moto Bridge) Industry standard CSI and DSI interfaces are supplied through the Moto Bridge as well as I2S audio for those Moto Mods requiring the camera or display interfaces. Power and charging block Contains the control, regulated and unregulated power control, battery selection, and charging paths for the Moto Mod system. See the DIP Switch B configuration section for the configuration options for this block. USB Connectors This set of three connectors enable connection of USB 2.0, MyDP and USB 3.1 peripherals, as well as Reference Moto Mod debug interfaces. Control and configuration of these connections is managed by the DIP switches. Debug Connector (USB 1) This Type C Connector is the debug port for all your projects using the Refe rence Moto Mod. The interfaces provided are detailed below. Port 1 - MuC Serial Wire Debug (SWD) Port 2 - MHB JTAG Port 3 - MuC Serial Console Port 4 - MHB Serial Console (Rx only) The Moto Mod will accept 500mA of current into USB Connector 1 to power th e Reference Moto Mod. USB Connector 1 will not charge the onboard battery or any battery included on your custom personality card. USB Type-C Connector (USB 2) This Type C Connector provides access to the following Mod interfaces: USB 3.1 - host and slave USB 2.0 - host only The onboard battery on the Reference Moto Mod can be charged via this port. The port is compliant with USB C DRP. MyDP connector (USB 3) This Micro B connector provides access to the following Mod interfaces: USB 2.0 - host only MyDP The Reference Moto Mod provides DC power out of the MyDP connector for USB Host mode support. DIP Switch Configuration Two DIP switches are provided to configure the Reference Moto Mod to support your Moto Mod project development. DIP Switch A: These switches control routing and selection of High Speed Signal Groups A and B. Group A signals are defined as USB 2.0 and MyDP and are controlled by switches A3 and A4. Group B signals include M-PHY, USB 3.1 and I2S functionality and are controlled by switches A 1 and A2.
