Product details
Overview
CYPD2803A109FNXITXTMA1 from Infineon is a USB Type-C electronically marked cable assembly (EMCA) controller compliant with USB PD 3.1 v1.4 and USB Type-C 2.1, supporting up to 240W (48V/5A), integrated VBUS-short-protected CC/VCONN transceivers, 47-byte programmable configuration storage, and RA termination on both VCONN1 and VCONN2 for passive cable implementations.
For engineers reviewing the CYPD2803A109FNXITXTMA1 datasheet, CYPD2803A109FNXITXTMA1 pinout, CYPD2803A109FNXITXTMA1 application, or CYPD2803A109FNXITXTMA1 equivalent, this device serves as a dedicated e-marker IC for Thunderbolt/non-Thunderbolt passive cables requiring EPR support, ±8 kV ESD protection, industrial temperature operation (–40°C to +85°C), and embedded oscillator-based timing.
Technical Context
The CYPD2803A109FNXITXTMA1 implements a full USB PD protocol engine with EMCA-specific state machines for cable identity authentication and power role negotiation. It integrates dual VCONN supply paths with independent RA termination and VBUS short-circuit protection on CC, VCONN1, and VCONN2 pins rated to 54 V.
Its 47-byte configuration memory is programmed over the CC interface using the EZ-PD™ Configuration Utility and CY4532 EVK, enabling vendor ID, product ID, cable type, and current rating storage. The internal 1.8-V core regulator (VCCD) outputs a stabilized rail for logic, decoupled via external 1-µF capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB PD Compliance | Revision 3.1 v1.4 - enables Extended Power Range (EPR) negotiation up to 48 V / 5 A |
| VCONN Operating Range | 2.7 V to 5.5 V - supports legacy and revised minimum 3 V VCONN per USB-C 2.1 |
| ESD Protection | ±8 kV contact / ±15 kV air gap (IEC61000-4-2 Level 4C) on CC/VCONN1/VCONN2 - ensures robust field reliability |
| Configuration Storage | 47 bytes EEPROM - stores vendor ID, product ID, cable type, SMT flag, and current rating for USB-IF certification |
| Supply Voltage Range | 2.7 V to 5.5 V on VCONN1/VCONN2 - eliminates need for external LDO in most cable designs |
| Sleep Current | 1.7 mA typical - minimizes standby power draw during unconnected or idle states |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade passive cable deployment |
Pinout & Package
Package: 9-ball Wafer-Level Chip-Scale Package (WLCSP), 0.4 mm pitch, bottom-side ball layout (balls-up view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | CC | Communication Channel I/O with integrated VBUS short protection - handles PD messaging and cable detection |
| A2 | VCONN2 | VCONN supply input with integrated 5.1-kΩ RA termination - powers downstream EMCA logic when plug B is host-facing |
| B1 | VCONN1 | VCONN supply input with integrated 5.1-kΩ RA termination - powers upstream EMCA logic when plug A is host-facing |
| B2 | VSS | System ground reference - mandatory connection to PCB GND plane for signal integrity and ESD return path |
| C1 | VCCD | 1.8-V core regulator output - requires 1-µF ceramic capacitor to ground for stability; not a power input |
Key Features
| Feature | Design Value |
|---|---|
| Dual VCONN support with RA weakening | Reduces quiescent current by disabling unused RA path - extends battery life in portable cable testers |
| Integrated oscillator | Eliminates external crystal or clock source - reduces BOM count and PCB area in ultra-thin cable assemblies |
| VBUS-to-CC/VCONN short protection | Withstands 54 V fault events - prevents latch-up or damage during hot-plug or miswiring in production |
| Single- or dual-chip EMCA topology support | Enables flexible cable architecture - one chip per cable (shared VCONN) or one per plug (independent VCONN routing) |
| Industrial temperature qualification | Validated across –40°C to +85°C - ensures reliable operation in automotive infotainment harnesses and industrial docking stations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C EMCA controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPD2802A109FNXITXTMA1 | Same CMG2 family, but supports only USB PD 3.0 (no EPR) and lacks TBT4/USB4 extended mode support | Restricted to ≤100W cables and non-Thunderbolt use cases | Select when EPR and USB4 compliance are unnecessary and cost sensitivity is higher |
| UPD350B-EVAL | Renesas UPD350B is a single-chip USB PD 3.1 EPR e-marker with 64-byte storage but no native Thunderbolt 4 flag support | Lacks TBT4 vendor-defined descriptor handling and requires external RA resistors | Choose for EPR-only applications where Thunderbolt certification is not required and board space allows discrete RA placement |
Compared with CYPD2803A109FNXITXTMA1, the CYPD2802 variant omits EPR and USB4 features, while the UPD350B requires external components and lacks Thunderbolt 4 metadata support - making the CYPD2803 optimal for certified high-power, multi-protocol passive cables.

FAQ
What is the maximum power level supported by CYPD2803A109FNXITXTMA1?
CYPD2803A109FNXITXTMA1 supports up to 240W (48V/5A) via USB Power Delivery 3.1 Extended Power Range (EPR). It implements full EPR message handling, including Source_Capabilities.Extended, Request.Extended, and Get_Source_Cap_Extended, enabling negotiation of voltages beyond 20V.
Does CYPD2803A109FNXITXTMA1 require an external crystal or clock source?
No. CYPD2803A109FNXITXTMA1 integrates a precision internal oscillator that meets USB PD timing requirements without external components. This eliminates the need for a crystal, saving PCB space and reducing BOM cost in compact cable plug modules.
How is configuration data programmed into the 47-byte storage?
Configuration data is programmed over the CC line using the Infineon EZ-PD™ Configuration Utility and CY4532 CCG3PA EVK. The utility communicates via USB-to-serial bridge to the CCG4 firmware on the EVK, which then writes vendor ID, product ID, cable type, and current rating to the device's internal nonvolatile memory.
Can CYPD2803A109FNXITXTMA1 operate with only one VCONN supply?
Yes. The device supports single-VCONN operation (e.g., VCONN1 only) in asymmetric cable topologies where only one plug connects to the DFP. Internal power management automatically selects the active VCONN path, disables the unused RA termination, and maintains full PD functionality without external switching.
