Product details
Overview
CYPD2134A-24LQXQ 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 notebook upstream ports, EMCA cables, and powered accessories.
For engineers reviewing the CYPD2134A-24LQXQ datasheet, CYPD2134A-24LQXQ pinout, CYPD2134A-24LQXQ application, or CYPD2134A-24LQXQ equivalent, key selection criteria include CC line BMC decoding latency, VCONN current capability (±150 mA), deep-sleep current (2.5 µA), industrial temperature support (−40°C to +105°C), and firmware reprogrammability via I²C or CC lines.
Technical Context
The CYPD2134A-24LQXQ implements a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b conversion at 300-kbps signaling, coupled with hardware-assisted PD message parsing and policy engine execution. Its dual VCONN drivers operate independently with ±150-mA sourcing/sinking per rail and integrated ESD protection (±8-kV contact, ±15-kV air).
It integrates two reconfigurable Serial Communication Blocks (SCB) supporting runtime-switchable I²C/SPI/UART modes, an 8-bit SAR ADC for voltage monitoring, six TCPWM channels for GPIO timing control, and a programmable I/O matrix enabling flexible signal routing without external logic.
Key Specifications

|---|---|
Use Scenario: Electronically marked active cables up to 2 m length with DisplayPort Alt Mode support. IC Role / Device Role / Timing Role: USB-PD policy engine and BMC transceiver managing cable identity, power negotiation, and role swap. Use Value: Integrated RA resistor and VCONN drivers eliminate discrete termination and boost circuit - reduces component count by ≥7 parts. | Use Scenario: USB-C docking stations with HDMI/USB3.0 expansion and 60-W power delivery. IC Role / Device Role / Timing Role: Downstream-facing port (DFP) controller handling source capability advertisement and VBUS control. Use Value: Dual VCONN rails power internal USB-C switch ICs and level shifters - enables self-powered operation without auxiliary DC jack. |
| Notebook Upstream Ports | USB-C Monitor Input Ports |

IC Role / Device Role / Timing Role: Upstream-facing port (UFP) controller detecting sink/source roles and enforcing PD contract compliance. Use Value: Deep-sleep current of 2.5 µA extends battery life during sleep mode - critical for >14-day standby requirement. | Use Scenario: Monitors with USB-C video input and downstream USB hub functionality. IC Role / Device Role / Timing Role: Dual-role port (DRP) managing simultaneous display data reception and peripheral enumeration. Use Value: Integrated 8-bit SAR ADC monitors VBUS voltage for dynamic power throttling - prevents overcurrent shutdown during high-resolution video streaming. |
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 (±200 mA), added hardware CRC engine | Required for programmable power supply (PPS) compliance in fast-charging adapters | Select when PPS negotiation or >60-W delivery is mandatory; otherwise CYPD2134A offers lower cost and footprint |
| TPS65987D | TI proprietary PD controller with integrated 20-V/3-A buck-boost regulator, no MCU subsystem | Used in monolithic PD+power path solutions where regulation and control are co-located | Choose only when combined PD control and power conversion are needed - not a firmware-reprogrammable MCU alternative |
Compared with CYPD3171-24LQXQ, this part lacks PPS and hardware CRC but delivers identical USB-C role detection and BMC timing at lower cost; versus TPS65987D, it provides full firmware flexibility and MCU-based customization but requires external power regulation.

FAQ
What is the maximum supported USB Power Delivery version and protocol features?
CYPD2134A-24LQXQ supports USB Power Delivery specification Revision 2.0 and Revision 3.0 (excluding Programmable Power Supply). It implements full BMC physical layer, structured VDM, SOP/SOP'/SOP" messaging, and hard reset recovery. It does not support PPS or extended messages beyond standard VDOs defined in the CCG2 firmware library.
Does this part require an external crystal or oscillator?
No. The CYPD2134A-24LQXQ integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz, fully compliant with USB PD timing requirements. No external clock source is needed for basic USB-C port operation or firmware updates.
Can the GPIO pins be used for analog sensing?
Yes. The device includes an 8-bit SAR ADC with up to 12 input channels mapped to GPIO pins. It supports single-ended measurements with 1.024-V internal reference, usable for VBUS monitoring, thermal sensing (with NTC), or adapter presence detection without external components.
How is firmware updated in-system after deployment?
Firmware can be updated in-system via two dedicated methods: (1) I²C interface using the EZ-PD™ Configuration Utility, or (2) directly over the CC line using vendor-defined messages - both require no physical debugger access and support field upgrades without disassembly.
