Product details
Overview
CYPD2134A-24LQXQT 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 CYPD2134A-24LQXQT datasheet, CYPD2134A-24LQXQT pinout, CYPD2134A-24LQXQT application, or CYPD2134A-24LQXQT equivalent, this device delivers production-ready USB-C port control with embedded PD state machine, runtime-reconfigurable SCB peripherals (I²C/SPI/UART), industrial temperature support (–40°C to +105°C), and wafer-level CSP or 24-pin QFN packaging options.
Technical Context
The CYPD2134A-24LQXQT implements a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b line coding at 300-kbps, coupled with hardware-assisted PD protocol engine handling SOP/SOP'/SOP" packet framing, collision avoidance, and structured VDM parsing. Its CC-line interface includes programmable current sources for DFP RP biasing and ESD-hardened ±8-kV contact/±15-kV air-gap protection per IEC61000-4-2 Level 4C.
It integrates two independent serial communication blocks (SCBs) that can be dynamically assigned as I²C master/slave, SPI master/slave, or UART with configurable baud rates up to 2 Mbps, alongside an 8-bit SAR ADC for analog monitoring and six TCPWM modules enabling GPIO-based PWM generation, timing-critical PD handshake signaling, and dead-time control in active cable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz - enables deterministic PD state machine execution and real-time BMC timing compliance. |
| Flash Memory | 32 KB - stores full USB PD 3.0 stack, vendor-defined VDMs, and field-upgradable firmware via CC or I²C. |
| SRAM | 4 KB - buffers PD message payloads, CC-line BMC bitstream, and runtime policy decision variables. |
| Type-C Transceiver | Integrated baseband PHY with RP/RD/RA resistors - eliminates external termination components and reduces BOM count by ≥4 passive parts. |

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, dual-role port controller with integrated buck converter driver | Targeted for AC/DC adapters and programmable power supplies requiring PPS regulation feedback | Select when PPS output control and higher flash capacity for complex VDM stacks are required |

FAQ
What is the maximum supported USB Power Delivery version and protocol features?
CYPD2134A-24LQXQT supports USB Power Delivery specification Revision 3.0, including all mandatory BMC physical layer functions, SOP/SOP'/SOP" packet handling, structured VDMs, and unstructured VDMs. It does not support Programmable Power Supply (PPS) mode or Fast Role Swap (FRS), as those require additional hardware resources present only in later CCG3/CCG4 generations.
Does this device require an external crystal or oscillator?
No. The CYPD2134A-24LQXQT integrates an Internal Main Oscillator (IMO) operating at 48 MHz with ±2% accuracy across temperature and voltage, eliminating the need for external timing components. An optional external crystal may be used for tighter frequency tolerance, but it is not required for USB PD compliance.
How is firmware updated in-system after deployment?
Firmware updates are supported via three channels: SWD debug interface for factory programming, I²C bus for host-controlled updates, and directly over the CC line using vendor-defined messages - enabling field upgrades without physical access or disassembly, critical for deployed docks and cable assemblies.
What thermal and reliability qualifications apply to this QFN package variant?
The 24-pin QFN variant (CYPD2134A-24LQXQT) is qualified per AEC-Q100 Grade 2 for extended industrial use (–40°C to +105°C), with JEDEC J-STD-020 moisture sensitivity level 3, 260°C reflow peak temperature rating, and >1000-cycle endurance for SWD programming cycles - validated for sustained operation in laptop docking stations and automotive USB-C interfaces.
