The RTS5400 is an advanced Type-C Power Delivery Controller that integrates all Type-C Channel Configuration (CC) functions, Power Delivery functions (including BMC PHY, protocol, policy engine, and policy manager), 10Gbps/480Mbps high speed MUXs and low speed MUXs, into a single chip. The RTS5400 can be used in various applications and dramatically reduces the system BOM cost.
A built-in 10Gbps 3:2 MUX can contribute to Type-C plug flipping and provide support for 4‑lane alternate mode (e.g. DisplayPort + USB3.X SS switching). An external 10Gpbs re-driver or re-timer chip is required to co-function with the RTS5400 for USB3.1 gen2 applications.
It also provides low-speed MUX switching for SBU1/2 in alternate mode (e.g. AUX+/- of DisplayPort). These MUXs simplify the design of the monitor or PCs systems, including DisplayPort or alternate modes. With the built-in 480Mbps MUX, the RTS5400 supports 1‑lane alternate mode (e.g. Sound Wire) + USB2.0 HS switching. This will easily handle Type-C connector D+/D- pins functional reconfiguration in direct connect applications such as a cradle dock, captive cable, or a detachable notebook.
The RTS5400 has various interfaces to communicate with other components, such as GPIO, I2C, and SMBUS. It is flexible for extending a variety of applications by using these interfaces as well as simplifying the addition of Type-C USB Power Delivery to any architecture. The RTS5400's SMBUS/I2C slave interface system can implement system control achieving all Power Delivery related functions, such as Cable detection, Power Negotiation, Power Swap, Data Swap, VCONN Swap, etc. The RTS5400 can be statically configured via SMBUS for customized extra functions. Via the I2C master interface, the RTS5400 can control/configure other chips in the system, such as a PMU with I2C, etc.
The RTS5400 can update its firmware using external SPI flash or EEPROM via a flexible ISP channel. The ISP function allows configuration of multiple features and settings. The ISP function is easy to use with USB/SMBUS/CCs and the RTS5400's download tool.
The RTS5400 adopts an industry standard 68-pin QFN 8mm*8mm green package.
