Product details
Overview
CYPD2103-14LHXI 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 USB-C EMCA cables and powered accessories for role negotiation and power contract management.
For engineers reviewing the CYPD2103-14LHXI datasheet, CYPD2103-14LHXI pinout, CYPD2103-14LHXI application, or CYPD2103-14LHXI equivalent, key selection criteria include CC line BMC decoding latency, VCONN current capability (±200 mA), deep-sleep current (2.5 µA), industrial temperature range (–40°C to +105°C), and QFN-24 package compatibility with USB-C port layout constraints.
Technical Context
The CYPD2103-14LHXI implements a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b conversion, coupled with hardware-accelerated PD protocol state machines. Its integrated transceiver includes programmable current sources for DFP RP (56 kΩ pull-up) and UFP RD (5.1 kΩ pull-down), plus RA (10 kΩ) for accessory identification.
It features two reconfigurable Serial Communication Blocks (SCB) supporting I²C, SPI, or UART at runtime, and an 8-bit SAR ADC for voltage monitoring. Clocking relies on an internal IMO (48 MHz main oscillator) and ILO (32.768 kHz low-power oscillator), eliminating external crystal requirements for USB-C port control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz - enables real-time PD message parsing and role swap execution within <100 µs response window. |
| Flash Memory | 32 KB - stores full USB PD 3.0 stack, vendor-defined policies, and field-upgradable firmware via CC or I²C. |
| SRAM | 4 KB - buffers PD message objects (SOP/SOP'/SOP'' packets) and maintains port state during negotiation. |
| VCONN Supply | Dual independent rails (VCONN1/VCONN2) - powers active cable electronics with isolation to prevent cross-rail fault propagation. |
| ESD Rating | ±8 kV contact / ±15 kV air per IEC61000-4-2 Level 4C - protects CC pins against electrostatic discharge in consumer-facing USB-C ports. |
| Operating Temp | –40°C to +105°C - supports deployment in notebook upstream ports and automotive infotainment USB-C hubs. |
| Supply Range | 2.7 V to 5.5 V - accommodates direct connection to VBUS or auxiliary 3.3-V rail without LDO overhead. |
Pinout & Package
Package: 4.0 mm × 4.0 mm, 24-pin QFN (0.55 mm pitch), exposed thermal pad, RoHS-compliant, industrial-grade moisture sensitivity level (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1, CC2 | USB Type-C Configuration Channel | Dual bidirectional BMC data lines - detect plug orientation, negotiate DRP/DFP/UFP roles, and exchange PD messages. |
| VCONN1, VCONN2 | Active Cable Power Supply | Independent 5-V outputs - deliver up to 200 mA each to power e-marked cable ICs without shared ground coupling. |
| VDDIO | I/O Supply Voltage | Configurable 1.71–5.5 V rail - enables mixed-voltage signaling with legacy controllers or level-shifted GPIO interfaces. |
| SWDIO, SWCLK | Serial Wire Debug Interface | 2-pin JTAG-compatible debug path - allows in-system programming and real-time firmware debugging without dedicated test pads. |
| GPIO[0:11] | Programmable Digital I/O | 12 general-purpose pins - support PWM, interrupt input, or status indication (e.g., power delivery state LED control). |
Key Features
| Feature | Design Value |
|---|---|
| In-system reprogrammable flash | Enables field firmware updates over CC line or I²C - critical for PD policy revision without hardware replacement in deployed accessories. |
| Integrated RP/RD/RA termination | Eliminates 6 external resistors and associated layout area - reduces BOM count and improves signal integrity on CC traces. |
| Run-time reconfigurable SCB | Single peripheral block dynamically switches between I²C/SPI/UART - simplifies host interface design and supports multiple system architectures. |
| Deep Sleep current: 2.5 µA | Extends battery life in portable accessories - maintains CC line monitoring while drawing less than typical coin-cell self-discharge rate. |
| Hardware USB-PD protocol engine | Offloads BMC timing-critical tasks from CPU - ensures sub-microsecond edge detection and deterministic PD message timing compliance. |
Applications
| USB-C EMCA Cables | USB-C Powered Accessories |
|---|---|
Use Scenario: Electronically marked active cables for 40-Gbps Thunderbolt 3/4 or 20-Gbps USB4 data transfer. IC Role / Device Role / Timing Role: Acts as cable identity authenticator and VCONN power manager - negotiates cable capabilities and supplies regulated 5 V to embedded retimers.

IC Role / Device Role / Timing Role: Manages upstream port PD contract, monitors CC line for attach/detach events, and controls VCONN for connected peripherals. Use Value: Supports simultaneous 100-W power delivery, DisplayPort Alt Mode handshaking, and dynamic role swapping without host CPU intervention. |
| Upstream Facing Ports | Downstream Facing Ports |
Use Scenario: Notebook or tablet USB-C port acting as host (DFP) for peripherals and chargers. IC Role / Device Role / Timing Role: Implements DFP role with RP termination, initiates PD negotiations, and manages VBUS sourcing under contract. Use Value: Delivers precise 5–20 V, 0–5 A power profiles while maintaining <15-ms PD message round-trip latency for responsive charging control. | Use Scenario: Monitor or external GPU enclosure accepting power and data from laptop. IC Role / Device Role / Timing Role: Functions as UFP with RD termination, reports sink capabilities, and requests specific PDOs during PD discovery.

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 3.1 compliant, supports PPS and extended messaging; 64-KB flash; dual-role port (DRP) optimized. | Required for Programmable Power Supply (PPS) negotiation in fast-charging adapters and GaN chargers. | Select when PPS, EPR, or extended structured VDM support is mandatory - not drop-in compatible due to enhanced PD stack and larger footprint. |
| TPS65987D | TI device with integrated 20-V, 5-A load switch; no embedded MCU; relies on external host processor for PD policy. | Suitable for host-managed PD ports where firmware flexibility is secondary to analog power path integration. | Choose when system already includes a capable host MCU and priority is analog power switching performance over autonomous PD negotiation. |
Compared with CYPD2103-14LHXI, CYPD3171 offers advanced PD 3.1 features but requires board redesign, while TPS65987D trades firmware autonomy for tighter analog integration - making CYPD2103 optimal for cost-sensitive, self-contained USB-C accessories needing full PD 3.0 independence.

FAQ
What is the maximum VCONN output current per rail on CYPD2103-14LHXI?
The CYPD2103-14LHXI provides two independent VCONN rails (VCONN1 and VCONN2), each capable of delivering up to 200 mA continuously. This rating is specified under worst-case thermal conditions at +105°C ambient and supports standard USB-IF e-marked cable power requirements without external boost circuitry.
Does CYPD2103-14LHXI support USB Power Delivery 3.1 or Programmable Power Supply (PPS)?
No. CYPD2103-14LHXI implements the USB Power Delivery 3.0 specification only. It does not support PPS, Extended Power Range (EPR), or structured vendor-defined messages introduced in PD 3.1. For those features, Infineon's CCG3 (e.g., CYPD3171) or CCG6 devices are required.
Can the CYPD2103-14LHXI operate without an external crystal or oscillator?
Yes. The device integrates a factory-trimmed internal main oscillator (IMO) running at 48 MHz and a low-power internal low-speed oscillator (ILO) at 32.768 kHz. These eliminate all external clock components, reducing BOM cost and PCB area - confirmed in Section 8.5.3 and 8.5.4 of the datasheet.
How many GPIO pins are available, and what are their voltage tolerance limits?
CYPD2103-14LHXI provides 12 GPIO pins (GPIO[0] through GPIO[11]), each configurable as input, output, or peripheral function. They support I/O voltages from 1.71 V to 5.5 V independently of core supply, enabling direct interfacing with 1.8-V logic, 3.3-V sensors, or 5-V indicators without level shifters.
