Product details

Overview

CYPD4225A0-33FNXIT from Infineon is a dual-port USB Type-C and Power Delivery 2.0 port controller IC featuring a 48-MHz Arm® Cortex®-M0 CPU, 128 KB flash, 8 KB SRAM, two integrated BMC transceivers, and VCONN FETs - designed for notebook host ports, AC/DC power adapters, and docking stations requiring full PD negotiation and role swap support.

For engineers reviewing the CYPD4225A0-33FNXIT datasheet, CYPD4225A0-33FNXIT pinout, CYPD4225A0-33FNXIT application, or CYPD4225A0-33FNXIT equivalent, key selection criteria include its 33-ball CSP package, –40°C to +105°C industrial temperature rating, integrated RP/RD termination, ±8-kV CC-pin ESD, and firmware-configurable dual-role port control per USB-IF compliance requirements.

Technical Context

The CYPD4225A0-33FNXIT implements two independent USB-PD 2.0 baseband PHY/MAC subsystems with integrated BMC transceivers, each supporting configuration channel (CC) detection, dead-battery termination, and fast role swap signaling. Its Arm® Cortex®-M0 core executes PD policy engine firmware with real-time response via four TCPWM blocks and four reconfigurable SCBs (I²C/SPI/UART).

It integrates dual 2.4 mm × 2.5 mm CSP-packaged VCONN FETs per port, hot-swappable CC/I²C I/Os, and system-level ESD protection on CC pins (±8 kV contact, ±15 kV air), all operating from a single 2.7–5.5 V supply with GPIO I/O voltage flexibility (1.71–5.5 V).

Key Specifications

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	40-pin QFN package, supports USB-PD 3.0 and extended data messaging; larger footprint and higher pin count	Required for PD 3.0 features (e.g., Fast Role Swap, PPS) and designs needing more GPIOs or SCB channels	Select when PD 3.0 compliance or additional serial interfaces are mandatory; not drop-in compatible due to package and pinout differences
CYPD3177-40LQXI	CCG3-based controller with 32-bit M0 core, 64 KB flash, PD 2.0 only, 40-pin QFN, no integrated VCONN FETs	Suitable for cost-sensitive single-port applications where external VCONN switching is acceptable	Choose for simpler, lower-cost implementations where board space allows discrete VCONN MOSFETs and fewer firmware features are needed

Compared with CYPD4226-40LQXI and CYPD3177-40LQXI, the CYPD4225A0-33FNXIT uniquely balances ultra-compact size, integrated VCONN FETs, and industrial temperature range - making it optimal for thermally constrained dual-port adapters and notebooks where PD 2.0 suffices and BOM reduction is critical.

FAQ

Does CYPD4225A0-33FNXIT support USB Power Delivery 3.0?

No. This 33-ball CSP variant supports USB-PD 2.0 only, as explicitly stated in the Infineon datasheet (Rev. *N, p.1). PD 3.0 features-including Fast Role Swap and Extended Data Messaging-are disabled in firmware for this package option, though the silicon contains the necessary PHY hardware.

What is the maximum current rating of the integrated VCONN FETs?

The integrated VCONN FETs are rated for continuous 600 mA per channel with an R_DS(on) of 200 mΩ at V_GS = 4.5 V, as confirmed in the Electrical Specifications section (p.27) of the datasheet. They meet USB-IF VCONN sourcing requirements for full-featured cables.

Can the CYPD4225A0-33FNXIT operate without an external crystal?

Yes. It includes an integrated main oscillator (IMO) and low-speed oscillator (ILO), eliminating the need for external timing components. The IMO provides 48 MHz clocking for the CPU and peripherals, and the ILO supports low-power sleep modes - both are factory-trimmed and require no external crystals or capacitors.

Is the 33-ball CSP package compatible with standard reflow profiles?

Yes. The CYPD4225A0-33FNXIT uses a standard Pb-free WLCSP package qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 3 (MSL3) and compatible with SnAgCu (SAC305) reflow profiles peaking at 260°C, as specified in Infineon's Packaging document (002-10113 Rev. *A).
