Product details
Overview
CYPD2122-20FNXIT from Infineon is a USB Type-C port controller IC implementing full USB Power Delivery 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 powered accessories for role detection, policy enforcement, and firmware-updatable power negotiation.
For engineers reviewing the CYPD2122-20FNXIT datasheet, CYPD2122-20FNXIT pinout, CYPD2122-20FNXIT application, or CYPD2122-20FNXIT equivalent, this device serves as a single-chip, reprogrammable, low-power (1.0 µA reset current) solution for CC-line BMC signaling, VCONN switching, and PD contract arbitration in compact industrial-grade USB-C endpoints.
Technical Context
The CYPD2122-20FNXIT integrates a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b conversion, coupled with hardware timers optimized for PD message timing compliance (tPDMsg, tPDDebounce). Its dual VCONN rails provide isolated 5-V supply paths for active cable electronics, each with independent enable control and ESD protection.
It implements a programmable I/O matrix with 12 GPIOs, two overvoltage tolerant (OVT) pins for CC line monitoring, and a 8-bit SAR ADC for auxiliary sensing - all managed via AHB-Lite interconnect and supported by SWD debug interface with four breakpoint comparators and two watchpoint comparators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz - enables real-time PD state machine execution with Thumb-2 instruction compatibility for firmware portability to M3/M4 platforms. |
| Memory | 32-KB flash + 4-KB SRAM - sufficient for full PD 3.0 stack plus vendor-specific policy engine and field-upgradable firmware. |
| Type-C PHY | Integrated baseband transceiver with RP/RD/RA resistors - eliminates external termination components and supports UFP/DFP/EMCA role detection without external biasing. |
| Power Modes | Reset: 1.0 µA, Deep Sleep: 2.5 µA, Sleep: 2.0 mA - enables battery-powered accessories to maintain CC-line presence while minimizing quiescent draw. |
| VCONN Support | Dual independent VCONN rails with integrated isolation - allows simultaneous powering of asymmetric cable electronics (e.g., one side active, one side passive) without cross-rail coupling. |
| ESD Rating | ±8-kV contact / ±15-kV air-gap on CC & VCONN - meets IEC61000-4-2 Level 4C for robust operation in consumer and industrial USB-C interconnects. |
| Operating Temp | –40°C to +105°C - qualified for extended industrial environments including automotive accessory modules and ruggedized docking stations. |
Pinout & Package
Package: 24-pin QFN (4.0 mm × 4.0 mm, 0.55-mm pitch), wettable flank, RoHS-compliant, rated for industrial and extended industrial temperature ranges.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | I/O supply rail | Independent 1.71–5.5-V supply enabling mixed-voltage signaling across GPIOs without level shifters. |
| VCONN1 / VCONN2 | Dual VCONN outputs | Separately controllable 5-V outputs with internal isolation; each powers distinct cable-side circuitry (e.g., retimers, muxes). |
| CC1 / CC2 | Configuration Channel I/O | OVT-capable bidirectional pins handling BMC signaling, pull-up/down detection, and PD message exchange per USB-C spec. |
| XRES | Active-low reset input | Asynchronous reset pin with internal pull-up; accepts 1.8-V logic; triggers full system restart including flash loader. |
| SWDIO / SWCLK | Serial Wire Debug interface | 2-pin JTAG-compatible debug path supporting in-system programming and real-time firmware inspection during development. |
Key Features
| Feature | Design Value |
|---|---|
| In-system reprogrammable flash | Enables field firmware updates over I²C or CC lines - critical for post-deployment PD policy changes and security patches in certified accessories. |
| Run-time reconfigurable SCB | Single serial communication block supports dynamic I²C/SPI/UART mode switching - simplifies host MCU integration and reduces BOM count in multi-interface systems. |
| Integrated oscillator | Eliminates external crystal or clock source - reduces PCB area, cost, and startup time while maintaining ±2% frequency stability over temperature. |
| GPIO voltage flexibility | 1.71–5.5-V I/O signaling range - permits direct interfacing with legacy 3.3-V or 5-V controllers without external level translators. |
| Deep Sleep wake-on-CC | Wakeup interrupt controller (WIC) responds to CC line activity in <10 µs - ensures immediate PD contract initiation upon plug detection with minimal latency. |
Applications
| USB-C EMCA Cables | USB-C Powered Accessories |
|---|---|
Use Scenario: Electronically marked active cables with signal integrity enhancement (e.g., DisplayPort Alt Mode, PCIe tunneling). IC Role / Device Role / Timing Role: Policy engine and BMC transceiver managing cable ID, power delivery capability, and role swap negotiation.

Use Value: Integrates RA termination and current-limited VCONN drive - eliminating discrete resistor networks and reducing bill-of-materials by ≥7 components. |
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 |
|---|---|---|---|
| CYPD2134-28LQXI | Higher pin count (32-QFN), adds USB 2.0 analog switch control and enhanced GPIO count (16 vs. 12). | Targeted at complex docks with integrated USB 2.0 switching and multi-port PD management. | Select when additional analog routing control or expanded I/O is required beyond CCG2's baseline feature set. |
| STUSB4500QTR | Dedicated PD controller (no embedded MCU), fixed-function silicon, no firmware update capability. | Suitable for cost-sensitive, static-role applications like basic chargers where policy is hard-coded. | Choose only if firmware flexibility, field updates, or custom policy logic are not required. |
Compared with CYPD2122-20FNXIT, the CYPD2134 offers expanded peripheral integration for multi-function hubs, while the STUSB4500 trades programmability for lower BOM cost and simpler validation - making CCG2 optimal for upgradable, role-adaptive USB-C endpoints.

FAQ
What is the maximum USB Power Delivery version supported by CYPD2122-20FNXIT?
CYPD2122-20FNXIT supports USB Power Delivery specification Revision 3.0, including Programmable Power Supply (PPS), Fast Role Swap (FRS), and extended message support. It implements the full PD 3.0 protocol stack in firmware, with hardware acceleration for BMC timing and CRC verification - enabling compliance with USB-IF certification test plans for PD 3.0 devices.
Does CYPD2122-20FNXIT require an external crystal or oscillator?
No. CYPD2122-20FNXIT integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz with ±2% accuracy over –40°C to +105°C, eliminating need for external timing components. An optional external clock input is available on XIN/XOUT pins but is not required for standard USB-C PD operation.
Can CYPD2122-20FNXIT be used in both DFP and UFP roles simultaneously?
No - CYPD2122-20FNXIT supports dual-role port (DRP) operation but not concurrent DFP/UFP functionality. It implements one USB-C port with dynamically switchable Rp/Rd termination and VCONN control, enabling role swap via PD messaging, but only one role is active at any given time per USB-C specification.
What debug interface does CYPD2122-20FNXIT provide for firmware development?
CYPD2122-20FNXIT provides a 2-pin Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, supporting full read/write memory access, breakpoint setting, and real-time variable inspection. The SWDIO and SWCLK pins are multiplexed with GPIOs and require no external debug probe beyond standard CMSIS-DAP or J-Link adapters.
