Product details
Overview
CYPD3135-40LQXQT from Infineon Technologies (formerly Cypress) is a single-port USB Type-C and Power Delivery 3.0 port controller IC featuring an ARM® Cortex®-M0 CPU running at 48 MHz, 128-KB flash, 8-KB SRAM, integrated BMC transceiver, dual VBUS gate drivers, 20V-tolerant VCONN FETs, hardware crypto engine, and system-level ±8-kV contact ESD protection. It serves as the core control unit for USB-C power negotiation, role swapping, and cable authentication in compact power adapters and docking stations.
For engineers reviewing the CYPD3135-40LQXQT datasheet, CYPD3135-40LQXQT pinout, CYPD3135-40LQXQT application, or CYPD3135-40LQXQT equivalent, key selection criteria include its native USB-PD 3.0 BMC PHY, dead-battery detection capability, integrated OVP/OCP monitoring, 40-QFN industrial-grade packaging (–40 °C to +105 °C), and support for firmware updates over CC, I2C, or USB interfaces.
Technical Context
The CYPD3135-40LQXQT implements a full USB-PD 3.0 protocol stack in hardware, including Fast Role Swap (FRS) transmit/detect, biphase mark coding (BMC) transceiver with 4b/5b encoding, and analog crossbar for DisplayPort AUX/SBU routing. Its dedicated USB-PD subsystem handles CC line termination (RP/RD/RA), VCONN switching, and HPD processing without MCU intervention.
It integrates two independent gate drivers supporting both N- and P-channel external VBUS FETs, a 20-V LDO regulator (VBUS_C), current-sense amplifier with programmable overcurrent threshold, and dual 8-bit SAR ADCs with internal bandgap reference - enabling real-time VBUS voltage/current monitoring and charger detection per USB BC1.2.

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 |
|---|---|---|---|
| STUSB4500QTR | Standalone USB-PD 3.0 PHY + MCU-less design; no integrated ARM core or flash memory. | Requires external microcontroller for policy engine; lacks Billboard class support and firmware upgradability. | Select when cost-sensitive designs use existing host MCU and require only physical-layer compliance. |
| TUSB8041A | USB 3.1 Gen 1 hub controller with embedded PD logic; no VCONN FETs or crypto engine. | Optimized for data-hub applications; limited to fixed DFP role and lacks dead-battery detection. | Select for USB-C hubs needing integrated data switching but not standalone PD port control. |
Compared with STUSB4500QTR and TUSB8041A, CYPD3135-40LQXQT delivers autonomous PD policy execution, secure firmware updates, and full role flexibility - making it optimal for self-contained adapters and docks where MCU offload and field-upgradable security are mandatory.

FAQ
Does CYPD3135-40LQXQT support USB Power Delivery 3.0 Programmable Power Supply (PPS)?
Yes, CYPD3135-40LQXQT supports USB PD 3.0 PPS through firmware implementation using its integrated BMC transceiver and real-time ADC monitoring. The ARM Cortex-M0 executes PPS voltage/current step control with ≤20-mV/≤50-mA resolution, and the hardware crypto engine validates PPS requests during authenticated sessions.
Can CYPD3135-40LQXQT operate without an external crystal?
Yes, it operates using its integrated IMO (Internal Main Oscillator) calibrated to ±2% accuracy across temperature and voltage - sufficient for USB-PD BMC timing and full-speed USB device operation. An external crystal is optional and only required for applications demanding <±0.25% frequency stability.
What GPIO configurations support DisplayPort Alt Mode signaling?
SBU1/SBU2 pins are routed through an analog crossbar to AUX_P/AUX_N, and DP/DM pins provide native USB 2.0 signaling. GPIOs P0[0]–P0[3] can be assigned to HPD control and AUX channel interrupts, enabling full DisplayPort sink/source handshake without external logic.
Is firmware update over the CC line supported out-of-box?
Yes, CYPD3135-40LQXQT includes built-in bootloader support for firmware updates over the CC line using vendor-defined messages (VDMs). The hardware crypto engine verifies signature integrity before flashing, and the 128-KB flash supports dual-bank operation for fail-safe updates.
