Summary of FTDI CHIP HIGH-SPEED USB BRIDGE ICS WITH TYPE-C CONTROLLERS
This article describes FTDI's high-speed USB bridge ICs featuring integrated Type-C and Power Delivery (PD) 3.0 controllers. These devices support bidirectional power negotiation, offering two PD ports where one combines data and power, while the other is power-only. They enable multi-channel interfacing to reduce system BOM by eliminating external USB hubs, allowing independent channel configuration for UART, MPSSE, or FIFO modes with varying baud rates. The chips support multiple voltage profiles configurable via EEPROM and include features like adjustable timeouts, hardware handshaking, and a wide industrial temperature range across various QFN package options.
Parts used in the FTDI High-Speed USB Bridge ICs:
- USB Type-C Connector
- Power Delivery (PD) 3.0 Controller
- External EEPROM
- 32-bit RISC Controller
- 1.2V LDO Regulator
- MPSSE Engine
- Virtual Com Port (VCP) Drivers
- D2XX Drivers
FTDI Chip High-Speed USB Bridge ICs with Type-C/PD 3.0 Controllers fully support the latest USB Type-C and Power Delivery (PD) standards. This enables the support for power negotiation with the ability to sink or source current to USB host devices. These high-speed USB bridge devices feature up to two PD ports viz, PD1 port and PD2 port. The PD1 port shares the same Type-C connector with USB data and the PD2 port is the power port only without USB data. The high-speed USB bridge ICs support 5V, 9V, 12V, 15V, and 20V PDO profiles and these profiles are configurable through an external EEPROM at power-up/reset.
The high-speed USB bridges offer up to 40Mbytes/s data rates and multi-channel interfacing. The benefit of a multi-channel bridge is that the system BOM is reduced by removing the need for a USB hub chip. Additionally, each channel of the device appears to the host PC as a separate device. This enables each channel to be independently configured for different modes such as UART, MPSSE, or FIFO. Also, with different parameters such as 4 UARTS all operating with different baud rates.
