Product details
Overview
CYPD3135-40LQXQ from Infineon Technologies (formerly Cypress) is a USB Type-C and Power Delivery 3.0 port controller IC with integrated ARM® Cortex®-M0 processor (48 MHz), 128-KB flash, 8-KB SRAM, dual VBUS gate drivers, hardware crypto engine, and ±8-kV IEC61000-4-2 ESD protection on CC/SBU/DP/DM/VBUS pins - deployed in notebook docking stations, USB-C power adapters, and monitor ports.
For engineers reviewing the CYPD3135-40LQXQ datasheet, CYPD3135-40LQXQ pinout, CYPD3135-40LQXQ application, or CYPD3135-40LQXQ equivalent, key selection criteria include USB-PD 3.0 BMC transceiver compliance, VCONN FET integration, dead-battery detection, fast role swap support, and industrial temperature range (–40 °C to +105 °C) operation.
Technical Context
The CYPD3135-40LQXQ implements a full USB Type-C physical layer with integrated BMC PHY, 4b/5b encoder/decoder, and 1.2-V analog front end. It supports programmable RP/RD/RA terminations for DFP/UFP/EMCA roles and includes dedicated hardware for Fast Role Swap (FRS) transmit/detect and VCONN capacitance discharge via leakers.
Its USB-PD subsystem integrates two 8-bit SAR ADCs, current sense amplifier (CSA) with overcurrent interrupt generation, dual independent gate drivers configurable for P- or N-channel VBUS FETs, and hardware-based OVP/OCP monitoring tied directly to VBUS_C regulation and discharge control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Lacks integrated MCU, flash, and crypto block; relies on external host processor for PD policy execution. | Requires external microcontroller for firmware updates and custom PD extensions - increases system complexity. | Preferred where cost-sensitive designs accept added host dependency and reduced security capability. |
| TUSB564RGER | USB-C redriver/re-timer only; no PD controller, BMC PHY, or VBUS switching capability. | Cannot negotiate PD contracts or manage power paths - limited to signal integrity enhancement in fixed-role systems. | Only suitable as companion device alongside a separate PD controller like CYPD3135-40LQXQ. |
Compared with STUSB4500QTR and TUSB564RGER, CYPD3135-40LQXQ delivers autonomous PD policy execution, embedded firmware upgradability, and integrated power FET control - reducing system-level component count and enabling secure, self-contained USB-C port management.

FAQ
Does CYPD3135-40LQXQ support USB Power Delivery 3.0 Programmable Power Supply (PPS)?
Yes. CYPD3135-40LQXQ implements full USB PD 3.0 specification compliance, including PPS mode with voltage steps of 20 mV and current steps of 50 mA. Its hardware BMC transceiver and real-time firmware stack enable sub-100-ms PPS voltage adjustment response during active charging sessions.
Can CYPD3135-40LQXQ operate without an external crystal?
Yes. The device integrates a factory-trimmed IMO (Internal Main Oscillator) capable of 48 MHz operation with ±2% accuracy across temperature and voltage - eliminating need for external crystal or oscillator in most USB-C port applications.
What is the maximum continuous current rating for the integrated VCONN FETs?
The integrated VCONN FETs support continuous 1-A output at 5 V with thermal derating above 70 °C ambient. Each FET includes built-in overtemperature shutdown and soft-start control to limit inrush current during cable connection.
Is CYPD3135-40LQXQ qualified for automotive applications?
No. CYPD3135-40LQXQ is specified for industrial temperature range (–40 °C to +105 °C) but is not AEC-Q100 qualified. It is intended for computing, consumer, and industrial USB-C infrastructure - not automotive ECUs or infotainment head units.
