Infineon Technologies CYPD2119-24LQXIT

Overview

CYPD2119-24LQXIT from Infineon is a USB Type-C port controller IC implementing full USB Power Delivery 3.0 and Type-C 1.4 compliance, featuring a 48-MHz Arm® Cortex®-M0 CPU, 32-KB flash, integrated baseband PHY with RP/RD/RA termination, dual VCONN rails, and ±8-kV IEC61000-4-2 ESD protection on CC pins - deployed in notebook upstream ports and EMCA cables.

For engineers reviewing the CYPD2119-24LQXIT datasheet, CYPD2119-24LQXIT pinout, CYPD2119-24LQXIT application, or CYPD2119-24LQXIT equivalent, this device delivers production-ready USB-C port control with firmware-updatable PD policy engine, low-power Deep Sleep (2.5 µA), and industrial temperature support (–40°C to +105°C) for embedded power delivery systems.

Technical Context

The CYPD2119-24LQXIT implements a dedicated USB-PD subsystem with BMC/4b5b encoding-decoding, integrated 1.2-V front-end transceiver, and hardware-based role detection via programmable RP (DFP), RD (UFP), and RA (EMCA) resistors. It supports both source and sink negotiation without external level shifters.

Its MCU subsystem includes serial wire debug (SWD), nested vectored interrupt controller (NVIC) with 32 interrupts, wakeup interrupt controller (WIC), and flash accelerator enabling single-cycle access at 24 MHz - all optimized for deterministic USB-PD timing response under 15-ms contract establishment.

FAQ

Does CYPD2119-24LQXIT support USB Power Delivery 3.0 with Programmable Power Supply (PPS)?

No. CYPD2119-24LQXIT implements USB PD 3.0 baseline specification but does not include PPS negotiation capability. PPS support begins with the CCG3 (CYPD3171) and later generations. This part supports Fixed Voltage (5/9/15/20 V) and Variable Voltage (e.g., 3.3–5.9 V) contracts only, as defined in PD 3.0 v1.2.

Can CYPD2119-24LQXIT operate as both a DFP and UFP simultaneously?

No. It supports single-port dual-role operation - meaning it can dynamically swap between DFP and UFP roles based on cable insertion and PD negotiation, but it cannot maintain both roles concurrently on separate interfaces. Dual-port or simultaneous DFP+UFP functionality requires CCG3 or CCG6 devices.

What debug interface does CYPD2119-24LQXIT use, and is SWD pinout compatible with standard ARM tools?

CYPD2119-24LQXIT uses Serial Wire Debug (SWD) with SWDIO and SWCLK pins, fully compliant with ARM CoreSight standards. It supports standard CMSIS-DAP, J-Link, and ST-Link V2 debug probes without adapter. The SWD interface enables full flash read/write, breakpoint setting, and real-time register inspection during PD firmware development.

Is external crystal required for CYPD2119-24LQXIT clock operation?

No. The device integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz, eliminating need for external crystal or resonator. An optional external 1–25 MHz crystal may be used for higher precision timing in specialized applications, but default operation relies entirely on the IMO with ±2% accuracy across temperature and voltage.
