About

EZ-PD? CCG3PA MCU subsystem

EZ-PD? CCG3PA includes an Arm? Cortex?-M0 CPU as part of the 32-bit MCU subsystem designed for low-power operation with clock gating. It also has a SWD interface with four address breakpoints and two data watchpoints for programming and debugging. The device has one bank of 64 KB flash with a flash accelerator tightly coupled to the CPU for improved access times. A supervisory ROM containing boot and configuration routines is also included. The USB PD subsystem interfaces with the Type-C USB port and includes a current sense amplifier, a high-voltage regulator, and fault protection comparators.

EZ-PD? CCG3PA USB PD subsystem

EZ-PD? CCG3PA features a USB PD subsystem that serves as the interface to the USB-C port. This subsystem incorporates a high-voltage regulator, dedicated OVP and UVP comparators, a current sense amplifier, and includes the necessary ESD support for Type-C interface pins. The USB PD physical layer includes a transmitter and receiver that communicate BMC-encoded data over the CC channel, utilizing the PD 3.1 standard.?

The USB PD block contains all termination resistors (Rp and Rd) and their switches as required by the USB PD specification. Rp and Rd resistors serve several purposes including connection detection, plug orientation detection, and establishing USB downstream facing port (DFP)/upstream facing port (UFP) roles. To accommodate various applications, EZ-PD? CCG3PA includes the required resistors on separate pads or pins with dead battery Rd resistors available on separate pads for power bank applications. For DFP applications, the CC pins are not bonded with the dead battery Rd.

EZ-PD? CCG3PA on-chip fault protection

EZ-PD? CCG3PA monitors VBUS undervoltage and overvoltage faults using internal resistor dividers which can be configured for fault thresholds and response times. The device also monitors VBUS overcurrent and short-circuit faults using internal current sense amplifiers, which are also configurable for fault thresholds and response times.?

Configurability includes choosing between auto-restart or latch-off for each fault. Overtemperature monitoring is accomplished using an external thermistor and an internal ADC. When the temperature exceeds the configured overtemperature limit, the USB-C port is disabled until the temperature drops below the set limit. CC1/CC2/DP/DM pins on EZ-PD? CCG3PA are protected against ESD, with a level of ¡À 8-kV contact discharge and ¡À15-kV air gap discharge based on IEC61000-4-2 level 4C. The device also provides protection against accidental short from VBUS_C to CC pins.

Why chose EZ-PD? CCG3PA?

EZ-PD? CCG3PA is a highly integrated solution allowing significant savings in terms of BOM and board area. It comes with a certified USB PD stack and supports field upgrades with free and fully compliant firmware. Its high degree of programmability makes EZ-PD? CCG3PA a flexible solution that can be tuned to fit various applications. The programming can be done using the included configuration utilities: EZ-PD? Configuration Utility and PSoC? Programmer. Customers can benefit from the variety of ready-to-download reference designs to speed up their development cycles and thus reducing the time to market.
