detection and charging. To support the latest USB-PD 3.0 specification, CCG6DF and CPU CCG6SF devices implement the FRS feature. Fast Role Swap The Cortex M0 in CCG6DF and CCG6SF devices is a 32-bit enables externally powered docks and hubs to rapidly switch to MCU, which is optimized for low-power operation with extensive bus power when their external power supply is removed. This clock gating. It mostly uses 16-bit instructions and executes a feature is supported for provider N-FET Gate Driver Output subset of the Thumb-2 instruction set, which enables fully (NGDO). SCP and RCP fault detection are not enabled during compatible binary upward migration of code to higher perfor- the FRS sequence and it is assumed that provider side supply is mance processors such as Cortex M3 and M4. Also included is present and higher than 4.85 V. a hardware multiplier, which provides a 32-bit result in one cycle. It includes an Interrupt Controller (the NVIC block) with 32 CCG6DF and CCG6SF devices are designed to be fully interop- Interrupt inputs and a Wakeup Interrupt Controller (WIC), which erable with revision 3.0 of the USB Power Delivery specification can wake the processor up from Deep Sleep mode. as well as revision 2.0 of the USB Power Delivery specification.

There are two VCONN FETs per port in CCG6DF The 16-KB RAM is used under software control to store and CCG6SF devices to power either CC1 or CC2 pins. These temporary status of system variables and parameters.

All GPIOs on ■ ADC these devices have access to the ADCs through the chip-wide analog mux. ■ SBU pass-through switch and USB HS mux ■ Undervoltage, overvoltage and Reverse-Current Protection on SBU Pass-Through Switch and USB HS Mux VBUS CCG6DF has integrated 2x SBU pass-through switches and 2x high-speed (480 Mbps) switches as shown in Figure 1. ■ High-side current sense amplifier for VBUS The SBU switch is a simple pass-through switch. The Type-C ■ VBUS Discharge facing SBU pins are protected from accidental short to VBUS. ■ VBUS Regulator The HS mux contains a 2x2 cross bar switch to route the system DP/DM lines to the Type-C top or bottom lines as per the CC ■ Consumer Gate Driver for VBUS NFET (Type-C plug) orientation and connect the Debug pins to unused ■ Integrated VBUS Provider path load switch with FRS DP or DM top or bottom pins. ■ VBUS tolerant SBU and CC pins USB-PD Physical Layer The USB-PD subsystem contains the USB-PD physical layer block and supporting circuits. The USB-PD Physical Layer consists of a transmitter and receiver that communicate BMC encoded data over the CC channel per the PD 3.0 standard. All communication is half-duplex.The Physical Layer or PHY practices collision avoidance to minimize communication errors on the channel. In addition, the USB-PD block includes all termination resistors (RP and RD) and their switches as required by the USB Type-C spec. Rp and Rd resistors are required to implement connection detection, plug orientation detection and for establishment of the USB source/sink roles. The RP resistor is implemented as a current source.
