Product details
Overview
CYPD4225-40LQXI from Infineon is a dual-port USB Type-C and Power Delivery 3.0 port controller IC featuring a 48-MHz Arm® Cortex®-M0 CPU, 128 KB flash, 8 KB SRAM, two integrated BMC transceivers, and on-die RP/RD termination resistors. It supports DRP operation with integrated VCONN FETs, fast role swap, and extended data messaging for notebook, docking station, and power adapter applications.
For engineers reviewing the CYPD4225-40LQXI datasheet, CYPD4225-40LQXI pinout, CYPD4225-40LQXI application, or CYPD4225-40LQXI equivalent, key selection considerations include dual-port PD 3.0 compliance, integrated CC line ESD protection (±8 kV contact), 40-pin QFN package thermal performance, and firmware-configurable SCB peripherals for I²C/SPI/UART.
Technical Context
The CYPD4225-40LQXI implements two independent USB-PD Baseband PHY/MAC subsystems with dedicated BMC encoding/decoding logic, enabling concurrent negotiation on both Type-C ports. Each port integrates programmable current sources for DFP (RP) and pull-down resistors for UFP (RD), plus dead-battery termination support.
Its MCU subsystem uses an AHB-Lite bus architecture with 4x TCPWM blocks and 4x reconfigurable Serial Communication Blocks (SCBs), allowing runtime assignment of I²C, SPI, or UART functions per port-critical for custom PD policy engine implementation and sideband communication in docked systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz - enables real-time PD protocol stack execution with deterministic timing for BMC decoding and policy engine response. |
| Flash / SRAM | 128 KB flash + 8 KB SRAM - sufficient for full USB-PD 3.0 stack, vendor-defined messages, and dual-port state machines without external memory. |
| USB-PD Support | USB-PD 3.0 compliant (including Extended Message Support) - required for Fast Role Swap, Battery Charging v1.2, and Vendor Defined Messages in modern adapters/docks. |
| CC Line ESD | ±8 kV contact / ±15 kV air discharge (IEC61000-4-2 Level 4) - eliminates need for external TVS diodes on CC1/CC2 lines, reducing BOM count and board area. |
| Operating Voltage | 2.7 V to 5.5 V - supports direct connection to 3.3 V or 5 V system rails; GPIOs tolerate 1.71–5.5 V signaling for mixed-voltage interface compatibility. |
| Package | 40-pin QFN (6.0 mm × 6.0 mm, 0.6 mm pitch) - provides thermal performance suitable for sustained 3 A/20 V PD operation in compact power adapters. |
| Temperature Range | –40°C to +105°C - qualified for industrial and mobile computing environments including laptop internal ports and active docks. |
Pinout & Package
Package: 40-pin QFN (6.0 mm × 6.0 mm, 0.6 mm pitch), exposed thermal pad, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1, CC2 | Configuration Channel Inputs/Outputs | Dual bidirectional BMC signaling lines for port discovery, role negotiation, and PD message exchange on Port 1 and Port 2. |
| VCONN1, VCONN2 | VCONN Power Switch Outputs | Integrated 200 mA FETs powering EMCA cables directly-no external MOSFET or gate driver required. |
| PORT0_SDA, PORT0_SCL | I²C Interface (Port 0) | Configurable SCB0 pins supporting host-side I²C communication for configuration or telemetry in docked systems. |
| PORT1_TX, PORT1_RX | UART Interface (Port 1) | Reconfigurable SCB1 pins used for debug logging, firmware updates, or sideband control in power adapters. |
| XRES | External Reset Input | Active-low asynchronous reset pin with internal pull-up; accepts 1.8 V–5.5 V logic levels for system-level reset coordination. |
| SWDIO, SWCLK | Serial Wire Debug Interface | 2-pin JTAG-compatible debug interface supporting full firmware development, breakpoint debugging, and flash programming. |
Key Features
| Feature | Design Value |
|---|---|
| Dual USB-PD BMC Transceivers | Two fully independent physical layers eliminate external transceiver ICs and reduce signal path latency for sub-100 ms role swaps. |
| Programmable SCBs | Four serial communication blocks dynamically assignable as I²C/SPI/UART-enables flexible peripheral integration (e.g., temperature sensor I²C + display SPI + debug UART). |
| Integrated VCONN FETs | On-chip 200 mA VCONN switches per port remove discrete FETs and gate drivers, simplifying layout and improving reliability in cable-powered accessories. |
| Deep Sleep Current | 2.5 µA typical - enables always-on CC monitoring while maintaining multi-week battery life in portable docks or battery-backed adapters. |
| Hot-Swappable I/Os | CC1/CC2 and Port 0 I²C pins rated for hot insertion - prevents latch-up during cable connect/disconnect events in live systems. |
Applications
| Notebook Internal USB-C Port | Multi-Port Power Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPD4226-40LQXI | Same die, identical features and pinout; differs only in factory-programmed firmware image (e.g., preloaded dock profile vs. adapter profile). | Targeted for evaluation kits and reference designs requiring out-of-box functionality without custom firmware flashing. | Select when rapid prototyping or production validation requires known-good firmware baseline. |
| STUSB4500QTR | Single-port PD 3.0 controller with embedded policy engine; no MCU subsystem, no flash/SRAM, no SCB peripherals. | Limited to fixed-function PD negotiation; cannot support custom vendor messages or sideband protocols like DisplayPort Alt Mode. | Select only for cost-sensitive, single-port applications where firmware flexibility and dual-port concurrency are not required. |
Compared with CYPD4226-40LQXI, this part offers identical hardware but requires customer firmware loading for custom use cases; versus STUSB4500QTR, it provides full MCU programmability and dual-port concurrency at higher BOM cost and design effort.

FAQ
Is CYPD4225-40LQXI pin-compatible with earlier CCG3 or CCG2 devices?
No. CYPD4225-40LQXI uses a 40-pin QFN package with unique pin assignments for dual-port BMC transceivers, VCONN FETs, and reconfigurable SCBs. It is not pin-compatible with CCG2 (32-pin QFN) or CCG3 (40-pin QFN with different function mapping). Migration requires PCB redesign and firmware adaptation.
Does CYPD4225-40LQXI support USB4 or Thunderbolt 3/4 Alt Mode?
Yes, but only as a supporting controller. CYPD4225-40LQXI handles USB-PD negotiation, CC line management, and VCONN supply for Alt Mode operation-it does not implement DisplayPort or PCIe tunneling. Full USB4/TB4 functionality requires companion retimers or switch ICs managed via its SCB interfaces.
What debug interfaces does CYPD4225-40LQXI support?
CYPD4225-40LQXI supports Serial Wire Debug (SWD) using SWDIO and SWCLK pins, compatible with standard ARM Cortex-M debug probes (e.g., Segger J-Link, ST-Link). It also supports UART-based bootloader mode via PORT1_TX/RX for firmware recovery without debugger hardware.
Can CYPD4225-40LQXI operate without external crystal or oscillator?
Yes. It integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz with ±2% accuracy over temperature and voltage, eliminating the need for external clock components. An optional external crystal can be used for tighter timing tolerance in precision applications.
