Product details
Overview
CYPD2105-20FNXIT 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 detection, policy enforcement, and firmware-updatable PD negotiation.
For engineers reviewing the CYPD2105-20FNXIT datasheet, CYPD2105-20FNXIT pinout, CYPD2105-20FNXIT application, or CYPD2105-20FNXIT equivalent, key selection criteria include CC-line BMC decoding latency, VCONN current capability (±100 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 CYPD2105-20FNXIT implements a dedicated USB-PD subsystem with baseband PHY supporting BMC encoding/decoding at 300 kbps, integrated 1.2-V front-end analog circuitry, and hardware-accelerated PD message parsing - enabling sub-100-µs CC line state response. Its dual independent VCONN rails drive active cable electronics with isolated 5-V supply switching and ±8-kV IEC61000-4-2 ESD protection on CC and VCONN pins.
The MCU subsystem includes 4-KB SRAM, serial wire debug (SWD) interface with four breakpoint comparators, and reconfigurable SCB blocks supporting runtime-switchable I²C/SPI/UART - allowing flexible host communication without firmware recompile. Clock system integrates IMO (internal main oscillator) eliminating external crystal requirement.

FAQ
What is the maximum supported USB Power Delivery version and protocol features?
CYPD2105-20FNXIT supports USB Power Delivery 3.0 specification, including structured VDMs, SOP'/SOP'' messaging, Fast Role Swap, and all mandatory PD 3.0 policy engine functions. It does not support Programmable Power Supply (PPS) or Extended Messages, which require CCG3 or later generations.
Does this device require an external crystal or oscillator?
No. The CYPD2105-20FNXIT integrates an internal main oscillator (IMO) operating at 48 MHz, fully meeting USB-PD timing requirements without external clock components - reducing bill-of-materials and PCB area while improving reliability.
How many GPIOs are available and what are their capabilities?
The device provides 12 programmable GPIOs supporting multiple functions: digital input/output, PWM generation, interrupt triggering, and analog input via an integrated 8-bit SAR ADC. All GPIOs operate across 1.71–5.5 V with independent VDDIO supply, enabling direct interfacing with diverse host logic families.
Can firmware be updated in the field without disassembling the end product?
Yes. Firmware updates can be performed in-system via I²C interface or directly over the CC line using vendor-defined messages - enabling remote bug fixes, policy updates, and feature enhancements without physical access to the device or PCB rework.
