Product details
Overview
CYPD2104-20FNXIT from Infineon is a USB Type-C port controller IC implementing full USB Power Delivery 2.0/3.0 protocol stack, featuring a 48-MHz Arm® Cortex®-M0 CPU, 32-KB flash, integrated Type-C transceiver with RP/RD/RA termination, and dual VCONN rails - deployed in USB-C EMCA cables and upstream-facing notebook ports.
For engineers reviewing the CYPD2104-20FNXIT datasheet, CYPD2104-20FNXIT pinout, CYPD2104-20FNXIT application, or CYPD2104-20FNXIT equivalent, key selection criteria include CC line BMC decoding latency, VCONN current capability (up to 150 mA per rail), deep-sleep power (2.5 µA), industrial temperature support (–40°C to +105°C), and in-system reprogrammability via SWD or CC interface.
Technical Context
The CYPD2104-20FNXIT implements a dedicated USB PD subsystem with baseband PHY supporting BMC modulation/demodulation and 4b/5b encoding at 300-kbps, coupled with hardware-accelerated PD message parsing and policy engine execution. Its dual VCONN supply architecture isolates VCONN1 and VCONN2 with independent current limiting and fault detection.
It integrates two reconfigurable Serial Communication Blocks (SCB) supporting I²C, SPI, or UART on-the-fly, plus an 8-bit SAR ADC for voltage monitoring and six TCPWM blocks for GPIO timing-critical functions such as CC line state sampling and VBUS discharge control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz - enables real-time PD policy engine execution with <100-µs interrupt latency |
| Flash Memory | 32 KB - stores full USB PD 3.0 firmware, vendor-defined modes, and field-upgradable configuration |
| SRAM | 4 KB - holds active PD message buffers, device descriptors, and runtime stack for concurrent CC line handling |
| VCONN Supply | Two independent rails, each up to 150 mA - powers active cable electronics without cross-rail coupling |
| ESD Rating | ±8 kV contact / ±15 kV air per IEC61000-4-2 Level 4C - protects CC and VCONN pins in unshielded cable environments |
| Operating Temp | –40°C to +105°C - supports extended industrial deployment in powered accessories and docking stations |
| Supply Range | 2.7 V to 5.5 V - accommodates direct connection to VBUS or auxiliary LDO outputs in portable systems |

Key Features
| Feature | Design Value |
|---|---|
| In-system reprogramming | Firmware updates over SWD debug interface or directly via CC line - eliminates need for dedicated programming fixtures in cable manufacturing |
| Integrated Type-C PHY | Single-chip solution with RP/RD/RA resistors and BMC transceiver - removes 6+ external components vs discrete PHY + MCU approach |
| Dual isolated VCONN | Hardware-isolated 150-mA rails with independent enable/control - enables simultaneous powering of separate cable-side ICs (e.g., mux + retimer) |
| Low-power Deep Sleep | 2.5 µA quiescent current with CC line wake capability - extends battery life in portable accessories during idle periods |
| GPIO flexibility | 12 programmable I/Os with 1.71–5.5 V signaling range - supports mixed-voltage system interfacing (e.g., 1.8-V logic + 5-V analog sensing) |
Applications
| USB-C EMCA Cables | USB-C Upstream Facing Ports |
|---|---|
Use Scenario: Electronically marked active cables for Thunderbolt 3/4 and USB4 compliance requiring embedded identity, bandwidth negotiation, and VCONN-powered retimers. IC Role / Device Role / Timing Role: Primary PD controller managing CC line BMC handshake, VCONN power delivery, and cable ID authentication via vendor-defined messages. Use Value: Eliminates external level shifters and discrete VCONN regulators; enables full cable certification with single-chip BOM. | Use Scenario: Notebook or tablet host ports that negotiate power roles (DFP/UFP), support alternate modes (DisplayPort Alt Mode), and manage VCONN for connected peripherals. IC Role / Device Role / Timing Role: Upstream-facing PD controller executing policy engine, managing port partner discovery, and controlling VBUS/VCONN sequencing per USB-C specification. Use Value: Reduces host SoC firmware burden; provides deterministic <5-ms CC response time for robust role swap and mode entry. |
| USB-C Powered Accessories | USB-C Docking Stations |
Use Scenario: Bus-powered monitors, hubs, or adapters drawing power from host while providing downstream ports and display output. IC Role / Device Role / Timing Role: Dual-role port controller acting as UFP when connected to host, DFP when powering downstream devices - dynamically switching based on CC state. Use Value: Enables automatic role negotiation without host intervention; supports 15-W power delivery with integrated VBUS monitoring. | Use Scenario: Multi-port docks connecting laptops to Ethernet, HDMI, USB-A, and SD card readers - requiring coordinated power allocation and port management. IC Role / Device Role / Timing Role: Central PD manager coordinating power budget across multiple downstream ports using PD contract negotiation and dynamic VBUS adjustment. Use Value: Prevents overcurrent faults during hot-plug events; enables shared VCONN distribution to multiple attached cables. |
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 |
|---|---|---|---|
| CYPD3171-24LQXIT | USB PD 3.0 + PPS support, 64-KB flash, dual-role port controller with integrated VBUS switch control | Required for programmable power supply (PPS) negotiation in GaN chargers and high-efficiency adapters | Select when PPS compliance or >30-W power negotiation is mandatory |
| STUSB4500QTR | Dedicated PD controller (no MCU), fixed-function policy engine, no flash/SRAM, supports PD 3.0 but no firmware customization | Suitable for cost-sensitive, single-role applications like fixed-function chargers where firmware updates are unnecessary | Select when minimal BOM count and zero firmware development effort are prioritized |
Compared with CYPD3171-24LQXIT, CYPD2104-20FNXIT offers lower gate count and power consumption but lacks PPS; versus STUSB4500QTR, it provides full firmware extensibility and dual VCONN control at higher design complexity.

FAQ
What is the maximum VCONN output current per rail on CYPD2104-20FNXIT?
The CYPD2104-20FNXIT supports up to 150 mA per VCONN rail (VCONN1 and VCONN2), with independent current limiting and thermal foldback. Each rail includes dedicated overcurrent detection and automatic shutdown recovery, enabling safe powering of retimers, redrivers, or mux ICs in active cables without external current-sense circuitry.
Does CYPD2104-20FNXIT support USB Power Delivery 3.0 and Programmable Power Supply (PPS)?
No - CYPD2104-20FNXIT implements USB PD 2.0 and basic PD 3.0 messaging but does not support PPS negotiation or variable voltage control. For PPS, Infineon recommends CYPD3171-24LQXIT or CYPD3125-40LQXIT, which include enhanced PD policy engines and hardware PPS waveform generation.
Can the CYPD2104-20FNXIT be programmed in-system after soldering?
Yes - firmware updates can be performed in-system via the SWD debug interface (2-wire JTAG) or directly over the CC line using Infineon's EZ-PD™ Configuration Utility. The device supports secure boot and authenticated firmware loading, with flash memory partitioned for bootloader, application, and configuration storage.
What package variants are offered for CYPD2104-20FNXIT?
CYPD2104-20FNXIT is available exclusively in the 24-pin QFN package (4.0 mm × 4.0 mm, 0.55 mm height, 0.4-mm ball pitch) with wettable flanks for automated optical inspection. It is not offered in WLCSP or SOIC variants; the -20FNXIT suffix explicitly denotes this QFN configuration with industrial temperature grading.
