Product details
Overview
CYPD3135-40LQXIT 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. It supports dead-battery detection, fast role swap, and VCONN switching for USB-C power adapters and docking stations.
For engineers reviewing the CYPD3135-40LQXIT datasheet, CYPD3135-40LQXIT pinout, CYPD3135-40LQXIT application, or CYPD3135-40LQXIT equivalent, key selection criteria include USB-PD 3.0 BMC transceiver compliance, dual 20-V-tolerant gate driver configuration for external VBUS FETs, integrated OVP/OCP, industrial temperature range (–40 °C to +105 °C), and 40-QFN package footprint compatibility.
Technical Context
The CYPD3135-40LQXIT implements a full USB-PD 3.0 protocol stack in hardware, including BMC encoding/decoding, 4b/5b conversion, and Fast Role Swap (FRS) transmit/detect logic. Its USB-PD subsystem integrates dedicated analog front-end circuitry for CC line signaling, programmable RP/RD/RA terminations, and VCONN leakers for EMCA cable discharge.
It features two independent 8-bit SAR ADCs with internal bandgap reference, configurable GPIO-to-analog mux routing, and four reconfigurable serial communication blocks (SCBs) supporting I²C (up to 1 Mbps), SPI, or UART-each with 8-deep FIFOs to reduce CPU interrupt latency during PD messaging or system telemetry.

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 | Standalone USB-PD 3.0 PHY with no embedded MCU; requires external microcontroller for policy engine. | Lacks integrated flash/SRAM and crypto block-unsuitable for secure firmware updates or complex state machines. | Select when cost-sensitive designs use existing host MCU and only require BMC transceiver + gate drivers. |
| TUSB8041RJER | USB 3.1 Gen 1 hub controller with integrated PD 2.0 support; no VCONN FETs or hardware crypto. | Supports multi-port hub functionality but lacks industrial temp rating and ±8-kV ESD on CC lines. | Select for USB-C hubs requiring SuperSpeed data + basic PD, not for standalone adapter or dock control. |
Compared with STUSB4500QTR and TUSB8041RJER, CYPD3135-40LQXIT delivers full self-contained PD 3.0 policy execution, hardware security, and robust ESD-making it optimal for certified power adapters and docks where firmware trust and safety certification (UL/IEC 62368) are mandatory.

FAQ
What USB-PD specifications does CYPD3135-40LQXIT support?
CYPD3135-40LQXIT fully implements USB Power Delivery 3.0, including Programmable Power Supply (PPS), Fast Role Swap (FRS), extended messaging, and hardware BMC transceiver compliance. It supports all standard PDOs up to 20 V / 5 A and vendor-defined messages for custom implementations, with built-in timers meeting USB-IF timing requirements for packet transmission and response windows.
Does CYPD3135-40LQXIT require an external crystal?
No. CYPD3135-40LQXIT integrates a precision IMO (Internal Main Oscillator) capable of 48 MHz operation without external components. The IMO is factory-trimmed to ±2% accuracy across temperature and voltage, eliminating BOM cost and board space for crystals or resonators while maintaining USB-PD timing compliance.
How is firmware updated in the field?
Firmware updates are performed via I²C, USB (Billboard class), or CC line using Cypress's EZ-PD Configuration Utility. The device supports secure authenticated updates via its hardware crypto engine-AES-128 decryption and SHA-256 signature verification ensure only signed images execute, preventing unauthorized or corrupted firmware loads.
Can CYPD3135-40LQXIT control both VBUS and VCONN simultaneously?
Yes. CYPD3135-40LQXIT integrates two independent VCONN FETs (for CC1/CC2) and dual gate drivers for VBUS_C and VBUS_P. It supports concurrent VCONN sourcing (up to 1 W) and VBUS switching (up to 100 W), with programmable timing for safe VCONN ramp-up before VBUS application and coordinated discharge during disconnect events.
