Product details
Overview
CYPD2119-24LQXI from Infineon is a USB Type-C port controller IC implementing full USB Power Delivery 2.0 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.
For engineers reviewing the CYPD2119-24LQXI datasheet, CYPD2119-24LQXI pinout, CYPD2119-24LQXI application, or CYPD2119-24LQXI equivalent, key selection criteria include CC line BMC decoding latency, VCONN current capability (±150 mA), deep-sleep current (2.5 µA), industrial temperature range (–40°C to +105°C), and QFN-24 package compatibility with USB-C system-level ESD requirements (±8-kV contact).
Technical Context
The CYPD2119-24LQXI implements a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b conversion, coupled with hardware-assisted PD message parsing and policy engine execution. Its dual VCONN drivers operate independently with integrated isolation, enabling simultaneous power delivery to cable electronics and accessory logic.
It integrates two reconfigurable Serial Communication Blocks (SCB) supporting I²C, SPI, or UART at runtime, 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 BMC symbol decode latency |

Key Features
| Feature | Design Value |
|---|---|
| In-system reprogrammable flash | Enables field firmware updates over CC or I²C - critical for USB PD specification compliance patches and vendor descriptor changes |
| Integrated oscillator | Eliminates external crystal or clock source - reduces BOM count and PCB area in space-constrained USB-C ports |
| Dual independent VCONN rails | Allows concurrent powering of asymmetric cable electronics (e.g., one side active, one side passive) with galvanic isolation |
| Run-time reconfigurable SCB | Single peripheral block dynamically switches between I²C/SPI/UART protocols - simplifies host interface design and debug access |
| System-level ESD on CC/VCONN | Meets IEC61000-4-2 Level 4C without external protection - validated for production use in consumer and industrial USB-C endpoints |
Applications
| USB-C Notebook Upstream Port | EMCA Active Cable |
|---|---|
Use Scenario: Host-side USB-C port in ultrabooks managing DRP role negotiation, VBUS sourcing/sinking, and display alt-mode handshaking. IC Role / Device Role / Timing Role: Primary PD policy engine and CC line transceiver - performs BMC decoding, PD message parsing, and role swap arbitration within <15-ms timing budget. Use Value: Enables single-chip USB-C port control with no external transceiver or PD controller, reducing solution size by 35% vs. discrete implementations. | Use Scenario: Electronically marked cable with e-marker IC, supporting >60 W power delivery and USB 3.1 Gen 2 data rates. IC Role / Device Role / Timing Role: Embedded e-marker controller - stores vendor ID, product ID, and power capabilities in flash, responds to SOP' messages within 200 µs. Use Value: Integrates RA termination, VCONN switching, and flash-based descriptor storage - eliminates need for separate e-marker ASIC and EEPROM. |
| Powered Docking Station | USB-C Monitor with Hub Function |
Use Scenario: Multi-port dock providing simultaneous USB data, DisplayPort alt-mode, and up to 100-W power delivery to laptop. IC Role / Device Role / Timing Role: Downstream-facing port (DFP) controller - manages VBUS discharge sequencing, CC line state machine, and PD contract renegotiation during hot-plug events. Use Value: Dual VCONN rails support auxiliary channel routing for DP alt-mode while maintaining independent power to embedded hub logic. | Use Scenario: Monitor with built-in USB-C hub, offering downstream USB peripherals and upstream video/data connectivity. IC Role / Device Role / Timing Role: Upstream-facing port (UFP) controller - handles sink-capability advertisement, VBUS fault detection, and CC line debouncing during monitor wake-from-sleep. Use Value: Deep-sleep current of 2.5 µA minimizes standby power draw when monitor is off but cable remains attached. |
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 |
|---|---|---|---|
| CYPD3171-24LQXQ | USB PD 3.0 + PPS support, 64-KB flash, higher VCONN drive (±300 mA), additional GPIOs | Required for programmable power supply (PPS) negotiation and higher-power docks (>100 W) | Select when PD 3.0 compliance or PPS is mandatory; not drop-in due to firmware and pinout differences |
| TPS65987D | Dedicated PD controller (no MCU), hardwired policy engine, no flash programmability, integrated high-side VBUS switch | Better suited for fixed-function, cost-sensitive DFP applications where firmware customization is unnecessary | Choose for simplified BOM and deterministic timing in non-reprogrammable port designs |
Compared with CYPD3171-24LQXQ and TPS65987D, CYPD2119-24LQXI offers optimal balance of field-upgradability, low-power operation, and USB PD 2.0 feature set for mid-tier notebooks, active cables, and powered accessories - avoiding over-specification while retaining full firmware control.

FAQ
Does CYPD2119-24LQXI support USB Power Delivery 3.0 or Programmable Power Supply (PPS)?
No. CYPD2119-24LQXI implements the USB PD 2.0 specification only. It does not support PPS, Fast Role Swap, or extended message structures introduced in PD 3.0. For PD 3.0 compliance, Infineon's CCG3 or CCG6 families are required - those devices include updated BMC PHY, larger flash, and enhanced policy engine firmware.
Can CYPD2119-24LQXI operate without an external crystal?
Yes. It integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz, fully sufficient for USB PD BMC timing and protocol compliance. No external crystal or clock source is required, reducing bill-of-materials and layout complexity in space-constrained USB-C ports.
What is the maximum continuous current supported on each VCONN rail?
Each VCONN rail (VCONN1 and VCONN2) supports ±150 mA continuous output current. This is verified per Infineon's electrical specifications and enables direct powering of common e-marker ICs, cable microcontrollers, and level-shifters without external regulators or current-boost circuits.
Is the CYPD2119-24LQXI pin-compatible with other CCG2 variants like CYPD2122?
No. While both belong to the CCG2 family, CYPD2119-24LQXI uses a 24-pin QFN package with specific pin assignments for dual VCONN, CC1/CC2, and GPIOs. CYPD2122 is offered in WLCSP and has different pin mapping, ball count, and thermal pad configuration - requiring PCB redesign for substitution.
