Product details
Overview
CYPD2134-24LQXIT 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.
For engineers reviewing the CYPD2134-24LQXIT datasheet, CYPD2134-24LQXIT pinout, CYPD2134-24LQXIT application, or CYPD2134-24LQXIT equivalent, key selection criteria include CC line BMC decoding latency, VCONN current capability (±150 mA), deep-sleep power (2.5 µA), industrial temperature range (−40°C to +105°C), and QFN-24 package compatibility with USB-C reference designs.
Technical Context
The CYPD2134-24LQXIT implements a dedicated USB-PD subsystem with baseband PHY supporting BMC modulation/demodulation and 4b/5b encoding at up to 300 kBd, coupled with hardware-accelerated PD message parsing and policy engine execution. Its dual VCONN drivers support independent sourcing/sinking on VCONN1 and VCONN2 with internal isolation.
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 VBUS discharge control and CC line state sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0, 48 MHz - enables deterministic USB-PD policy engine execution within 15-ms response window for SOP' messages. |
| Flash Memory | 32 KB - stores full USB PD 3.0 firmware, vendor-defined modes, and field-upgradable configuration tables. |
| VCONN Drive | ±150 mA per rail - powers active cable electronics without external boosters in EMCA applications. |
| CC Line ESD | ±8 kV contact / ±15 kV air (IEC61000-4-2 Level 4C) - eliminates need for external TVS diodes on CC pins. |
| Operating Temp | −40°C to +105°C - supports deployment in notebook chassis near CPU/GPU thermal zones. |
| Supply Range | 2.7 V to 5.5 V - compatible with single-supply VBUS or auxiliary 3.3-V rail in portable accessories. |
| Deep Sleep Current | 2.5 µA - extends battery life in always-connected USB-C accessories during idle periods. |
Pinout & Package
Package: 4.0 mm × 4.0 mm, 0.55 mm pitch, 24-pin QFN with exposed thermal pad (RoHS-compliant, moisture sensitivity level 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1, CC2 | USB Type-C Configuration Channel | Dual bidirectional BMC I/O with integrated 5.1-kΩ RD (UFP), 10-kΩ RA (EMCA), and programmable RP (DFP) termination. |
| VCONN1, VCONN2 | Active Cable Power Rails | Independent 5-V output drivers with current limiting and thermal shutdown; isolated from each other and VDDIO. |
| VDDIO | I/O Supply Voltage | 1.71–5.5 V input enabling mixed-voltage signaling across GPIOs without level shifters. |
| SWDIO/SWCLK | Serial Wire Debug Interface | 2-pin debug port supporting in-system programming and real-time firmware trace without halting USB-PD operation. |
| GPIO[0:11] | Programmable Digital I/O | 12 pins configurable as open-drain, push-pull, or analog inputs; six support PWM for VBUS discharge timing control. |
Key Features
| Feature | Design Value |
|---|---|
| In-system reprogrammable flash | Enables field firmware updates over I²C or CC lines without removing the device from PCB - critical for PD policy revision compliance. |
| Integrated Type-C transceiver | Eliminates external PHY and discrete termination resistors, reducing BOM count by ≥7 components and layout area by 30%. |
| Dual independent VCONN drivers | Supports simultaneous powering of two separate active cable segments (e.g., DisplayPort Alt Mode + USB3.1 Gen2) with fault isolation. |
| Run-time reconfigurable SCBs | Allows dynamic switching between I²C (for PMIC communication), SPI (for flash expansion), and UART (for debug logging) without reset. |
| Hardware USB-PD policy engine | Offloads full PD 3.0 message parsing, CRC validation, and state machine transitions from CPU - reduces firmware complexity and latency. |
Applications
| USB-C Notebook Upstream Port | EMCA Active Cable |

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 |
|---|---|---|---|
| CYPD3171-24LQXIT | USB PD 3.1 compliant, supports EPR (Extended Power Range) up to 240 W; adds hardware PPS regulator and enhanced VBUS monitoring ADC. | Required for new designs targeting >100-W charging or EPR-certified accessories. | Select when future-proofing for USB PD 3.1 EPR or needing tighter VBUS regulation (±5 mV) in high-power adapters. |
| STUSB4500QTR | Standalone PD controller (no MCU); fixed-function policy engine; no flash programmability; supports only USB PD 3.0 baseline. | Suitable for cost-sensitive, single-mode applications (e.g., fixed 60-W chargers) where firmware updates are unnecessary. | Choose for simplified BOM and lower unit cost in volume production where feature flexibility is not required. |
Compared with CYPD3171-24LQXIT, this part lacks EPR support but offers identical footprint and pinout for drop-in replacement in legacy PD 3.0 systems; versus STUSB4500QTR, it provides full firmware customization and dual VCONN - essential for active cables and DRP docks.

FAQ
What is the maximum supported USB Power Delivery version and message rate?
CYPD2134-24LQXIT implements full USB PD 3.0 compliance, including structured VDMs, unstructured VDMs, and custom vendor-defined messages. It supports BMC signaling at 300 kBd, meeting USB-C specification timing for SOP, SOP', and SOP'' packet transmission with hardware CRC generation and validation.
Does this device require an external crystal or oscillator?
No external clock source is required. The device integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz with ±2% accuracy across temperature and voltage, sufficient for USB-PD timing and BMC decoding without external components.
Can the GPIO pins tolerate 5-V signals when VDDIO is set to 3.3 V?
Yes. All 12 GPIO pins are 5-V tolerant regardless of VDDIO setting (1.71–5.5 V), enabling direct interfacing with 5-V peripherals such as USB3.0 redrivers or HDMI level translators without external level shifters.
How is firmware updated in-system after PCB assembly?
Firmware updates are performed via I²C interface using the EZ-PD™ Configuration Utility or over the CC line using vendor-defined PD messages. Both methods support full flash reprogramming without SWD debugger, enabling field updates through host OS or embedded bootloader.
