Product details
Overview
CYPD2122-24LQXI 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 notebook upstream ports, EMCA cables, and powered accessories requiring bidirectional role negotiation and 100-W power routing.
For engineers reviewing the CYPD2122-24LQXI datasheet, CYPD2122-24LQXI pinout, CYPD2122-24LQXI application, or CYPD2122-24LQXI equivalent, key selection criteria include CC line BMC decoding latency, VCONN current capability (±150 mA), deep-sleep current (2.5 µA), GPIO voltage flexibility (1.71–5.5 V), and industrial temperature support (−40°C to +105°C).
Technical Context
The device integrates a dedicated USB-PD subsystem with baseband PHY handling BMC modulation/demodulation and 4b/5b encoding, coupled with hardware-accelerated PD message parsing and policy engine execution. Its dual VCONN drivers support independent sourcing/sinking per CC line, enabling active cable and UFP/DFP reconfiguration without external FETs.
The MCU subsystem includes SWD debug interface, nested vectored interrupt controller (NVIC) with 32 IRQ inputs, and wakeup interrupt controller (WIC) for Deep Sleep wake-up via CC or VCONN events - ensuring sub-3-µs response to plug/unplug or role swap requests per USB Type-C specification Rev 2.1.

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 power range (up to 240 W); adds hardware-based fast role swap (FRS) | Required for USB PD 3.1 EPR applications like high-end gaming laptops and server PSUs | Select when PPS regulation or >100-W contracts are mandatory; not drop-in due to firmware and descriptor changes |
| TPS65987DHLR | TI analog-front-end architecture with integrated buck-boost regulator; no embedded MCU - relies on host processor for PD policy | Suitable for host-processor-controlled systems where firmware customization is centralized | Choose when leveraging existing Linux/RTOS PD stack; requires additional PMIC integration and increases software complexity |
Compared with CYPD3171-24LQXQ, CYPD2122-24LQXI offers lower BOM cost and simpler firmware maintenance for USB PD 3.0 applications, while TPS65987DHLR shifts policy execution burden to host - increasing design effort but enabling unified PD management across multiple ports.

FAQ
What is the maximum supported USB Power Delivery version for CYPD2122-24LQXI?
CYPD2122-24LQXI implements USB Power Delivery Specification Revision 3.0, including all mandatory features for Source, Sink, and Dual-Role Port operation. It supports Programmable Power Supply (PPS) negotiation only in firmware versions v3.3.0 and later, but does not support Extended Power Range (EPR) defined in PD 3.1. Full compliance is verified against USB-IF Test Plan v1.4a.
Does CYPD2122-24LQXI require an external crystal oscillator?
No. The device integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz with ±2% accuracy across temperature and voltage, eliminating need for external timing components. An optional external 32.768-kHz crystal may be used for RTC functions, but is not required for USB PD operation or CC line timing.
Can CYPD2122-24LQXI operate as both a source and sink simultaneously?
No. CYPD2122-24LQXI operates as a single-role or dual-role port (DRP), but cannot source and sink power concurrently on the same port. In DRP mode, it alternates roles based on CC line detection and PD messaging - e.g., advertising source capabilities when connected to a sink, then switching to sink mode upon receipt of a Request message.
How is firmware updated in-system for CYPD2122-24LQXI?
Firmware updates occur via two paths: (1) SWD interface using Infineon's KitProg3 programmer for full flash reprogramming during development; (2) runtime application updates over I²C or CC line using the EZ-PD™ Configuration Utility - enabling field upgrades without physical access to debug pins.
