Product details

Overview

CYPD2103-20FNXIT from Infineon is a USB Type-C port controller IC implementing full USB Power Delivery 2.0/3.0 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, powered docks, and notebook upstream/downstream ports.

For engineers reviewing the CYPD2103-20FNXIT datasheet, CYPD2103-20FNXIT pinout, CYPD2103-20FNXIT application, or CYPD2103-20FNXIT equivalent, this page delivers verified technical context, package mapping to 24L QFN (4.0 × 4.0 mm), low-power sleep modes (2.5 µA deep sleep), ESD robustness (±8-kV contact), and real-world firmware update paths via I²C or CC lines.

Technical Context

The CYPD2103-20FNXIT integrates a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding and 4b/5b conversion, coupled with hardware-based PD message parsing and policy engine execution. Its dual VCONN rails provide isolated 5-V power delivery to cable electronics, while the programmable SCB blocks support runtime reconfiguration between I²C, SPI, and UART for host interface flexibility.

It implements a full USB Type-C state machine including role detection (DFP/UFP/DRP), plug orientation sensing, and VCONN source switching - all managed by the Cortex-M0 core with SWD debug access and 8 KB SROM boot firmware. The integrated IMO eliminates external crystal requirements for USB timing compliance.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm® Cortex®-M0, 48 MHz - enables deterministic PD protocol timing and firmware-upgradable policy engine.
Flash Memory	32 KB - sufficient for full USB PD 3.0 stack plus vendor-specific policy logic and firmware updates.
SRAM	4 KB - supports concurrent USB PD messaging, Type-C state management, and host interface buffering.
Type-C PHY	Integrated baseband transceiver with RP/RD/RA resistors - eliminates external termination components and reduces BOM count.
VCONN Support	Dual independent rails with internal isolation - powers active cable electronics without cross-rail interference.
ESD Rating	±8 kV contact / ±15 kV air per IEC61000-4-2 Level 4C - protects CC pins during hot-plug events in consumer and industrial environments.
Operating Temp	–40°C to +105°C - qualified for extended industrial applications including automotive docking stations and ruggedized peripherals.

Pinout & Package

Package: 4.0 mm × 4.0 mm, 24-pin QFN (0.55 mm pitch), wettable flank, RoHS-compliant, thermal pad exposed on bottom.

Pin/Terminal	Circuit Role	Design Meaning
VDDIO	I/O supply rail	Independent 1.71–5.5 V supply enabling mixed-voltage signaling with host MCU or PMIC.
VCONN1 / VCONN2	Dual isolated VCONN outputs	Each drives separate 5-V cable electronics; internal isolation prevents fault propagation between lanes.
CC1 / CC2	Configuration Channel I/O	Dual-purpose analog/digital pins handling BMC signaling, plug detection, and VBUS presence sensing.
SCL / SDA	I²C host interface	Configurable as standard I²C bus for firmware update and configuration read/write from system MCU.
GPIO[0:11]	Programmable digital I/O	12 general-purpose pins supporting PWM, interrupt, or status indication; configurable pull-up/down.

Key Features

Feature	Design Value
In-system reprogrammable flash	Enables field firmware updates over I²C or CC line - critical for PD policy revision and security patching without hardware change.
Run-time reconfigurable SCB	Single peripheral block dynamically switches between I²C/SPI/UART protocols - simplifies host interface design and supports multiple system architectures.
Integrated IMO oscillator	Eliminates external crystal or clock source - reduces component count and PCB area while meeting USB timing jitter requirements.
Deep Sleep current	2.5 µA - extends battery life in portable accessories during idle periods without sacrificing wake-on-CC event responsiveness.
System-level ESD protection	±8-kV contact ESD on CC/VCONN pins - meets IEC61000-4-2 Level 4C without external TVS diodes, lowering system cost and board space.

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
CYPD2104-20FNXIT	Same die, 64-KB flash (vs. 32 KB); identical pinout and peripherals.	Supports larger firmware images - required for multi-protocol stacks (e.g., PD + DisplayPort Alt Mode + audio).	Select when future firmware expansion or additional protocol support is anticipated.
STUSB4500QTR	Dedicated PD controller (no MCU); fixed-function silicon; no flash/SRAM; supports PD 3.0 only.	Limited to basic PD negotiation - no custom policy logic, no firmware updates, no GPIO control.	Select for cost-sensitive, single-role applications where programmability is unnecessary.

Compared with CYPD2104-20FNXIT, the CYPD2103-20FNXIT trades flash capacity for lower unit cost and smaller firmware footprint; versus STUSB4500QTR, it provides full MCU programmability and dual-VCONN flexibility at higher BOM and development complexity.

FAQ

What firmware update methods does CYPD2103-20FNXIT support?

CYPD2103-20FNXIT supports three firmware update paths: (1) SWD programming during production using Infineon's KitProg programmer; (2) I²C-based updates from a host MCU; and (3) CC-line updates for DFP or cable applications - all leveraging the same flash architecture without requiring external memory.

Does CYPD2103-20FNXIT require an external crystal?

No. It integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz, fully compliant with USB Type-C timing requirements. No external crystal or clock source is needed, reducing bill-of-materials and layout complexity.

Can CYPD2103-20FNXIT manage both CC1 and CC2 simultaneously?

Yes. Its dual CC I/O subsystem monitors both CC1 and CC2 pins concurrently for plug orientation detection, role determination (DFP/UFP/DRP), and BMC signaling - enabling full USB Type-C specification compliance including audio adapter accessory mode.

What is the function of the two VCONN pins on CYPD2103-20FNXIT?

VCONN1 and VCONN2 are independently controlled 5-V power outputs with internal isolation. They supply power to active cable electronics (e.g., e-markers, redrivers) on separate CC lanes - preventing fault coupling and enabling asymmetric cable topologies such as hybrid USB-C/DisplayPort cables.
