USB-C Thunderbolt Device or Dock using Cypress USB-C controllers
Below section shows steps on how to design USB-C Thunderbolt Device or Dock using Cypress USB-C controllers
Identify the reference design which closely resembles your end-product, select CCGx part and USB Billboard (if needed)
Reference Design | Application | # of TBT Ports | Self / Bus Powered | CCGx Part | USB Billboard | Firmware |
Tapex Creek | Titan Ridge based device (compatible with only TBT host) |
2 | Self | CYPD5235-96BZXI | CY7C65215-32LQXI | Download |
Tahini Creek | Dual port dock using Titan Ridge | 2 | Self | CYPD5235-96BZXI | No | Download |
Tortilla Creek | Single port low-cost dock using Titan Ridge | 1 | Self | CYPD5137-40LQXI | No | Download |
Apex Creek | Alpine Ridge based device (compatible with only TBT host) | 2 | Self | CYPD5235-96BZXI | CY7C65215-32LQXI | Download |

Download the schematic & board layout files for the selected reference design from Intel’s IBL website (Thunderbolt developer account is required to access the collateral)

Contact local sales to get the Thunderbolt device configuration utility which can configure vendor- and design-specific parameters (VID, PID, Power profiles, etc) in the CCG5 firmware. This tool will generate CCG5 BIN & HEX file

Download USB Billboard firmware from here (if needed)

Program CCG5 and USB Billboard controller (if needed) using Miniprog3 over SWD lines during design development cycle and 3rd party programming house before PC assembly during mass production
