Product details

Overview

CYPD2134-24LQXI 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 CYPD2134-24LQXI datasheet, CYPD2134-24LQXI pinout, CYPD2134-24LQXI application, or CYPD2134-24LQXI equivalent, key selection criteria include CC line BMC decoding latency, VCONN current sourcing 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 CYPD2134-24LQXI integrates a dedicated USB PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b conversion, coupled with hardware-accelerated PD message parsing and policy engine execution. Its dual VCONN rails are independently controlled and isolated, enabling simultaneous power delivery to cable electronics and accessory logic.

It uses an internal 48-MHz IMO (no external crystal required) and supports runtime reconfiguration of two SCB peripherals for I²C, SPI, or UART - critical for firmware updates over CC lines or host microcontroller coordination in dual-role port designs.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm® Cortex®-M0 @ 48 MHz - enables real-time PD state machine execution with <100-µs BMC edge response
Flash Memory	32 KB - stores full USB PD 3.0 stack, vendor-defined modes, and field-upgradable firmware
VCONN Supply	Two independent rails, ±150 mA each - powers active cable electronics without external regulators
ESD Rating	±8-kV contact / ±15-kV air per IEC61000-4-2 Level 4C - eliminates need for external TVS on CC/VCONN pins
Operating Temp	–40°C to +105°C - qualified for notebook docking stations and automotive-infotainment USB-C ports
Supply Range	2.7 V to 5.5 V - compatible with single-cell Li-ion, USB bus, or 3.3-V/5-V system rails
Deep Sleep Current	2.5 µA - sustains CC line monitoring during system suspend with <1-second wake latency

Pinout & Package

Package: 4.0 mm × 4.0 mm, 0.55 mm pitch, 24-pin QFN (wettable flank), RoHS-compliant, moisture sensitivity level 3.

Pin/Terminal	Circuit Role	Design Meaning
CC1, CC2	USB Type-C Configuration Channel	Dual-directional BMC signaling interface with integrated termination and ESD protection
VCONN1, VCONN2	Active Cable Power Rails	Independent 5-V supplies with current limiting and thermal foldback for cable electronics
VDDIO	I/O Voltage Supply	Configurable 1.71–5.5 V rail enabling mixed-voltage GPIO interfacing (e.g., 1.8-V I²C + 3.3-V UART)
SWDIO/SWCLK	Serial Wire Debug Interface	2-pin debug port supporting in-system programming and real-time trace without halting PD operation
GPIO[0:11]	Programmable Digital I/O	12 pins with configurable pull-up/down, open-drain, and interrupt-on-change for status LEDs, reset control, or sideband signals

Key Features

Feature	Design Value
In-system reprogrammable flash	Enables field firmware updates over I²C or CC line - no JTAG programmer required in end-product
Integrated Type-C transceiver	Eliminates discrete RP/RD/RA resistors and front-end analog components - reduces BOM count by ≥7 parts
Dual isolated VCONN outputs	Supports bidirectional active cable topologies (e.g., Thunderbolt 3/4 compliant cables) without external isolation switches
Run-time reconfigurable SCB	Single peripheral block dynamically switches between I²C master/slave, SPI master/slave, or UART - simplifies host interface design
Low-power Deep Sleep mode	2.5 µA quiescent current with CC line wake capability - extends battery life in portable dock applications

Applications

USB-C Notebook Upstream Port

EMCA Active Cable

Use Scenario: Laptop USB-C port negotiating power role (DFP/UFP) and data mode (DisplayPort Alt Mode) with dock or monitor.

IC Role / Device Role / Timing Role: Policy engine and BMC transceiver managing PD contract negotiation, VCONN power sequencing, and CC line state detection.

Use Value: Enables seamless dual-role port behavior with <150-ms PD contract establishment and guaranteed ±8-kV ESD robustness on exposed ports.

Use Scenario: Electronically marked USB-C to USB-C cable with embedded logic for authentication and signal integrity tuning.

IC Role / Device Role / Timing Role: Cable-side PD controller providing RA termination, VCONN-powered MCU, and CC-line firmware update path.

Use Value: Supports certified cable identification and dynamic parameter adjustment (e.g., SMT resistor trimming) via CC-line firmware download.

Powered USB-C Accessory

USB-C Docking Station Port

Use Scenario: USB-C hub with integrated HDMI, USB 3.0, and PD charging delivering up to 60 W to connected laptop.

IC Role / Device Role / Timing Role: Downstream-facing port (DFP) controller handling sink detection, Rp-based current advertisement, and VCONN supply to attached cables.

Use Value: Integrates all Type-C port logic into single chip - eliminates discrete CC switch, level shifters, and termination networks.

Use Scenario: Multi-port desktop dock with independent PD contracts per port and shared system power management.

IC Role / Device Role / Timing Role: Independent port controller per USB-C receptacle, coordinating with host MCU via I²C to aggregate power budget and thermal limits.

Use Value: Enables per-port PD contract isolation - prevents single-port fault from disrupting power delivery to other devices.

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), includes hardware crypto engine	Required for programmable power supply (PPS) compliance and secure firmware signing in chargers	Select when PPS negotiation or secure boot is mandatory; not drop-in due to larger flash layout and crypto peripheral mapping
TPS65987D-24RGER	TI proprietary PD controller with integrated buck-boost converter, no MCU core, fixed-function PD state machine	Suitable for cost-sensitive, single-role DFP applications where firmware customization is unnecessary	Select only for fixed-function charger/dock designs - lacks programmability, SCB flexibility, and GPIO count of CYPD2134

Compared with CYPD3171-24LQXQ, CYPD2134-24LQXI offers lower BOM cost and smaller footprint but omits PPS and cryptographic acceleration; versus TPS65987D-24RGER, it provides full firmware control at the expense of requiring external power regulation.

FAQ

What is the maximum supported USB Power Delivery specification for CYPD2134-24LQXI?

CYPD2134-24LQXI implements the complete USB Power Delivery 3.0 specification including structured VDMs, unstructured VDMs, and SOP'/SOP'' messaging. It does not support Programmable Power Supply (PPS) profiles, which require hardware extensions present only in CCG3/CCG6 derivatives.

Does CYPD2134-24LQXI require an external crystal oscillator?

No. The device integrates a factory-trimmed 48-MHz internal main oscillator (IMO) with ±2% accuracy over temperature and voltage - sufficient for USB PD BMC timing and eliminating BOM cost and PCB area for external crystals or resonators.

Can CYPD2134-24LQXI support dual-role port (DRP) operation?

Yes. Its firmware-configurable CC line detection, RP/RD/RA termination switching, and dual VCONN control enable full DRP behavior - verified in Infineon's reference designs for notebook ports and multi-function docks supporting both source and sink roles.

What debug interfaces are available for firmware development?

CYPD2134-24LQXI supports Serial Wire Debug (SWD) via SWDIO/SWCLK pins for full JTAG-equivalent debugging, plus in-system firmware updates over I²C or directly through the CC line using EZ-PD™ Configuration Utility - no external debugger required for production programming.
