Product details
Overview
CYPD2122-24LQXIT 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 notebook upstream ports, EMCA cables, and powered accessories requiring robust CC-line BMC decoding and firmware-updatable PD policy engine.
For engineers reviewing the CYPD2122-24LQXIT datasheet, CYPD2122-24LQXIT pinout, CYPD2122-24LQXIT application, or CYPD2122-24LQXIT equivalent, this device delivers production-ready USB-C port control with in-system reprogrammable flash, ±8-kV CC-line ESD protection, industrial temperature support (–40°C to +105°C), and hardware-accelerated PD state machine execution - critical for certified cable, adapter, and host-port designs.
Technical Context
The CYPD2122-24LQXIT implements a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b conversion, coupled with a hardened CC-line analog front end operating at 1.2 V. Its dual independent VCONN power rails enable simultaneous sourcing to both cable-side VCONN paths with internal isolation.
It integrates two reconfigurable Serial Communication Blocks (SCB) supporting I²C, SPI, or UART at runtime, plus an 8-bit SAR ADC and six TCPWM channels - enabling real-time voltage monitoring, firmware-triggered policy decisions, and GPIO-driven status signaling without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz - executes full USB PD 3.0 policy engine with deterministic timing for BMC packet response & role swap negotiation. |
| Memory | 32-KB flash + 4-KB SRAM - stores certified PD firmware, vendor-defined descriptors, and runtime policy tables; supports over-the-wire updates via CC or I²C. |
| Type-C PHY | Integrated baseband transceiver with RP/RD/RA resistors - eliminates external termination components and enables automatic DFP/UFP/EMCA role detection on plug-in. |
| VCONN Support | Dual independent VCONN rails with internal isolation - powers active cable electronics on both sides without cross-rail coupling or external FETs. |
| ESD Rating | ±8-kV contact / ±15-kV air-gap on CC pins per IEC61000-4-2 Level 4C - meets USB-IF compliance requirements for end-product certification. |
| Operating Temp | –40°C to +105°C - qualified for extended industrial environments including laptop docking stations and automotive-infotainment USB-C ports. |
| Supply Range | 2.7 V to 5.5 V - compatible with single-supply systems using 3.3-V or 5-V rails; GPIOs support 1.71–5.5-V signaling for mixed-voltage interface flexibility. |
Pinout & Package
Package: 4.0 mm × 4.0 mm, 24-pin QFN (0.55-mm pitch), thermally enhanced with exposed thermal pad - optimized for compact USB-C port PCB layouts and thermal dissipation in high-density adapters and notebooks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | I/O supply rail | Independent 1.71–5.5-V supply for GPIO voltage level setting; decoupled from core logic to support mixed-signal interfacing. |
| VCONN1 / VCONN2 | Dual VCONN outputs | Each drives up to 1-W load at 5 V; internally isolated to prevent fault propagation between cable-side circuits. |
| CC1 / CC2 | Configuration Channel I/O | Differential BMC transceivers with integrated 1.2-V biasing and ESD protection - handle plug detection, orientation, and PD message exchange. |
| VBUS_DET | VBUS presence monitor | Analog input with programmable threshold - detects VBUS presence/absence for safe port power sequencing and sink/source role management. |
| SCB0_SDA / SCB0_SCL | I²C interface | Configurable as master/slave; used for host MCU communication or firmware update; supports standard/fast-mode speeds up to 400 kHz. |
| GPIO_0–GPIO_11 | Programmable I/O | 12 general-purpose pins with interrupt capability; configurable as PWM, analog input (via ADC), or digital control for LED/status signaling. |
Key Features
| Feature | Design Value |
|---|---|
| In-system reprogrammable flash | Enables field firmware updates over CC line or I²C - critical for post-deployment PD specification compliance patches and vendor descriptor changes. |
| Run-time reconfigurable SCB | Single peripheral block dynamically switches between I²C/SPI/UART protocols - reduces BOM count and simplifies board layout versus fixed-function UART/I²C chips. |
| Integrated oscillator | Eliminates external crystal or clock source - reduces component count, PCB area, and startup time while maintaining USB-PD timing accuracy. |
| Deep Sleep current | 2.5 µA - allows sustained battery-powered operation in portable accessories during cable disconnect or idle port states. |
| Hardware TCPWM | Six independent timer/PWM blocks - drive RGB LEDs, generate precise timing for VBUS discharge control, or implement custom status blink patterns without CPU overhead. |

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 |
|---|---|---|---|
| CYPD3123-40LQXIT | USB PD 3.0 + PPS support; 64-KB flash; dual-role port controller with hardware PPS modulation | Required for programmable power supply (PPS) chargers and GaN adapters needing dynamic voltage adjustment | Select when PPS compliance or >32-KB firmware space is mandatory; adds cost and complexity for basic PD 3.0 use cases |
| STUSB4500QTR | Dedicated PD controller (no MCU); fixed-function state machine; no flash or firmware update capability | Suitable only for static-role applications (e.g., fixed-source adapters) without field update needs | Choose for lowest BOM cost and smallest footprint where firmware flexibility and multi-role support are unnecessary |
Compared with CYPD3123-40LQXIT, this part offers lower system cost and smaller footprint for non-PPS applications; versus STUSB4500QTR, it provides full firmware upgradability and DRP capability - making it optimal for certified, future-proof USB-C accessories requiring long-term compliance maintenance.

FAQ
What is the maximum supported USB Power Delivery specification for CYPD2122-24LQXIT?
CYPD2122-24LQXIT fully implements USB Power Delivery 3.0 specification, including structured VDMs, unstructured VDMs, and fast role swap. It does not support Programmable Power Supply (PPS) mode, which requires hardware modulation circuitry present only in CCG3/CCG6 devices.
Does CYPD2122-24LQXIT require an external crystal or oscillator?
No. The device integrates a factory-trimmed internal main oscillator (IMO) capable of 48 MHz operation with ±2% accuracy - sufficient for USB PD BMC timing requirements. External clock sources are optional and not required for USB-IF certification.
Can CYPD2122-24LQXIT operate as both a DFP and UFP simultaneously?
No. It supports dual-role port (DRP) operation but only one active role at a time - determined by CC line state and firmware policy. Simultaneous DFP+UFP operation is not supported; that capability requires multi-port controllers like CCG6.
How is firmware updated in the field for CYPD2122-24LQXIT?
Firmware updates occur via two methods: over the CC line using BMC-encoded packets (for cable and DFP applications), or over I²C using the EZ-PD™ Configuration Utility. Both methods write directly to the internal 32-KB flash without requiring SWD debug interface access.
