Choose a Cypress-origin EZ-PD controller by the job it must do: CCG2 is the compact programmable option for USB-C port roles, CCG3PA2 is aimed at power adapters and cable or charger designs, and CCG6SF/CCG6DF target notebook and desktop designs with one or two ports. Automotive CCG3PA variants are a separate choice for vehicle charging applications. These single-chip devices integrate USB Type-C/PD control with varying levels of power-path control and protection; confirm the exact part number, revision and availability with Infineon, which maintains the current product pages.
What a single-chip USB Type-C controller integrates
EZ-PD controllers combine a USB Type-C/Power Delivery transceiver and policy-control microcontroller with functions that would otherwise require additional components. Depending on the family, integration can include termination resistors, ESD or VBUS protection, regulation control, load-switch control and USB data-path resources. The exact feature set varies substantially, so “single-chip” does not mean that every design can omit external power components or firmware work.
For selection, first establish the port’s role and power behavior, then check the USB PD revision and PPS requirement, VBUS range, power-path and protection needs, USB data routing, package and temperature grade, and firmware configurability.
How the Cypress-origin families differ
| Family | Best-fit design | Distinguishing integration and capability |
|---|---|---|
| CCG2 | Compact cable, charger, host, sink/source or dual-role designs | Programmable controller with explicit UFP, DFP and DRP support; integrated transceiver, termination resistors and ESD. |
| CCG3PA2 | USB-C power adapters and cable or charger products | USB PD 3.0 with PPS; configurable Rp/Rd/Ra; support for one Type-C plus one Type-A; integrated VBUS feedback/control and ESD. |
| CCG6SF / CCG6DF | Notebook and desktop designs requiring one or two USB-C ports | Single-port (CCG6SF) or dual-port (CCG6DF) family with a 20-V regulator, provider load-switch control, consumer NFET gate driver, SBU pass-through and USB high-speed mux. |
| Automotive CCG3PA variants | Rear-seat chargers, infotainment and other automotive charging designs | AEC-Q100 24-pin QFN family with automotive temperature range, integrated current/voltage control, fault monitoring, and CC/VBUS short protection. |
What to check for each controller
CCG2: choose for flexible port roles
CCG2 explicitly supports UFP (upstream-facing), DFP (downstream-facing) and DRP (dual-role) operation. That makes it a candidate when a compact design needs a programmable Type-C controller across source, sink or dual-role configurations. Verify the specific device’s power-path, protection, data-routing and firmware requirements rather than assuming that the family’s role support alone covers the whole product.

CCG3PA2: choose for adapter and charger integration
CCG3PA2 is the more targeted fit for adapter and cable/charger products that need USB PD 3.0 and PPS. Its documented integration includes configurable Rp/Rd/Ra, VBUS feedback/control, ESD, and the ability to support one Type-C port alongside one Type-A port. The datasheet specifies a 32-bit Arm Cortex-M0, two 64-KB flash blocks, and 32-pin QFN or 30-ball CSP package options; those figures describe the documented device, not every EZ-PD controller.
CCG6SF and CCG6DF: choose for PC port and data-path needs
CCG6SF serves single-port PC designs and CCG6DF serves dual-port designs. In addition to PD control, the family provides SBU pass-through and a USB high-speed mux, along with load-switch and NFET gate-driver controls for power-path designs. The Cypress 2022 datasheet specifies an Arm Cortex-M0 running at 48 MHz, 64-KB flash, 96-KB SROM and 16-KB SRAM for the documented CCG6DF/CCG6SF family. Infineon describes CCG6 as compatible with USB PD 3.0; check the exact part and current documentation for implementation details.

Automotive CCG3PA: choose for vehicle charging requirements
Automotive CCG3PA variants address rear-seat charging and infotainment applications, rather than being interchangeable with the general-purpose adapter-focused CCG3PA2. The Cypress 2020 datasheet specifies 64-KB flash, 8-KB SRAM and 3.0–24.5-V operation, as well as ESD ratings of ±8 kV contact and ±15 kV air. Its listed protection includes overvoltage, overcurrent, undervoltage, short-circuit and overtemperature monitoring. These are datasheet specifications; confirm that the selected variant and system design meet the intended vehicle qualification and electrical requirements.

A controller IC is for integration into a product PCB, where the designer must implement the surrounding power path, connectors and any other required circuitry, then develop or configure firmware. An evaluation board is the more practical starting point for prototyping or assessing a controller before committing to a custom board.

Cypress announced the CY4531 EZ-PD CCG3 evaluation kit as a development option. It is a documented kit, not evidence of current stock or compatibility with every CCG3-family part. Check the kit’s exact supported device and documentation, along with current availability, before ordering. “USB-C PD controller development board” is a useful search phrase, but verify the seller’s listing against the board documentation.
Quick Recap
Best Value
- THREE PRESOLDERED USB-C BOARDS FOR MORE PROJECTS - Keep one Nano on a breadboard, embed another in a robot or sensor node and reserve the third for testing; one USB-A to USB-C data cable is included for programming, while jumper wires, sensors and breadboards are sold separately
- ATMEGA328P PERFORMANCE IN A COMPACT FORMAT - Run familiar 5 V, 16 MHz AVR sketches with 32 KB flash, 2 KB SRAM and 1 KB EEPROM, plus 14 digital I/O pins, 6 PWM outputs and 8 analog inputs for LEDs, buttons, displays, sensors, motor drivers and data logging
- CH340 USB SETUP WITH PRACTICAL UPLOAD GUIDANCE - Install the CH340 driver if no serial port appears, select Nano and the correct COM port, then upload a Blink test; use the included USB-A to USB-C cable because the current board does not support USB-C to USB-C host cables
- PRESOLDERED HEADERS SAVE BREADBOARD SPACE - The 18 × 45 mm footprint arrives ready to plug into a solderless breadboard, while UART, I2C and SPI support serial modules, displays, storage and sensors without soldering header pins before the first project
- POWER AND MODEL EXPECTATIONS - Use USB-C, 7-12 V VIN or a regulated 5 V input, share ground and drive motors or relays through suitable modules; this classic Nano V3-style board has no Wi-Fi, Bluetooth or features from Nano Every, Nano 33, Nano ESP32 or Nano R4

How to choose and verify a part
- Define the port configuration. Record port count and whether each port is a source, sink or dual-role port. This distinguishes role flexibility such as CCG2 from the one- or two-port PC focus of CCG6.
- Specify power behavior. Identify the required USB PD revision, whether PPS is needed, the VBUS operating range, and any current/voltage regulation or power-path switching functions.
- Check protection and data routing. Compare the required fault protections with what the selected part integrates. For PC designs, specifically check whether the SBU pass-through and USB high-speed mux resources fit the data-path architecture.
- Match package and environment. Confirm package, temperature grade and market qualification requirements. Use an automotive variant when the design requires automotive-oriented characteristics; do not infer qualification from a general-purpose family name.
- Verify the exact device and revision. Cypress is the historical brand context for these products; Infineon maintains current family product pages. Check current part status, datasheet revision, firmware resources and authorized-distributor availability for the exact orderable part.
