Product details
Overview
CYPD3135-32LQXQ from Infineon Technologies (formerly Cypress) is a fully integrated USB Type-C and Power Delivery 3.0 port controller with ARM® Cortex®-M0 core, 128-KB flash, 8-KB SRAM, dual VBUS gate drivers, integrated VCONN FETs, and system-level ±8-kV contact ESD protection - deployed in notebooks, docking stations, and USB-C power adapters.
For engineers reviewing the CYPD3135-32LQXQ datasheet, CYPD3135-32LQXQ pinout, CYPD3135-32LQXQ application, or CYPD3135-32LQXQ equivalent, key selection criteria include USB-PD 3.0 BMC transceiver compliance, 48-MHz real-time PD protocol response, hardware crypto for firmware authentication, 20-V-tolerant regulator, and industrial-grade (–40 °C to +105 °C) operation in 32-QFN package.
Technical Context
The CYPD3135-32LQXQ implements a dedicated USB-PD subsystem with integrated BMC PHY supporting Fast Role Swap (FRS), programmable RA/RP/RD terminations, and analog crossbar for DisplayPort AUX/SBU routing. It embeds two 8-bit SAR ADCs with internal bandgap reference and temperature sensing capability.
Its MCU subsystem delivers deterministic USB-PD timing via four reconfigurable SCBs (I2C/SPI/UART), four TCPWM blocks for timing-critical control loops, and hardware crypto acceleration for AES, SHA-1/SHA-2, and CRC - all synchronized under a single 48-MHz clock domain with deep-sleep wake-up via WIC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M0 @ 48 MHz - enables real-time USB-PD state machine execution with <10 µs interrupt latency for BMC frame handling. |
| Flash / SRAM | 128 KB flash / 8 KB SRAM - sufficient for full USB-PD 3.0 stack, Billboard device class, and custom policy engine with field-upgradable firmware. |
| USB-PD Support | USB-PD 3.0 + BMC transceiver + FRS - supports bidirectional power negotiation, extended messaging, and sub-100-ms role swap without host intervention. |
| VCONN & VBUS Control | Integrated 5-V VCONN FETs + dual gate drivers for external N/P-FETs - eliminates need for discrete level-shifters and reduces BOM count in 20-V input adapter designs. |
| ESD Protection | ±8 kV contact / ±15 kV air-gap on CC, SBU, DP/DM, VBUS - meets IEC61000-4-2 Level 4C without external TVS diodes. |
| Operating Range | 2.7 V to 21.5 V supply - supports wide-input AC/DC adapters and battery-backed dock systems across industrial temperature range (–40 °C to +105 °C). |

| DP / DM | USB 2.0 Full-Speed PHY | Dedicated differential pair with integrated 5.0-V-to-3.3-V regulator - connects directly to USB 2.0 upstream/downstream ports without level-shifting. |
| SCB0–SCB3 | Serial Communication Blocks | Four reconfigurable I2C/SPI/UART peripherals - SCB0 I2C pins are overvoltage-tolerant (up to 5.5 V), enabling direct connection to legacy PMICs or sensors. |
Key Features
| Feature | Design Value |
|---|---|

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 | ARM Cortex-M0 core, 64-KB flash, no integrated VCONN FETs or hardware crypto; requires external 5-V LDO and authentication IC. | Limited to basic PD 2.0 sink-only or fixed-role applications; lacks FRS, extended messaging, and DisplayPort AUX routing. | Select when cost sensitivity outweighs security and DP Alt Mode support - adds ≥3 external components and increases firmware validation scope. |
| TUSB8041RJBR | Dedicated USB 3.2 Gen 2 hub with embedded PD controller (no MCU); 128-KB ROM, no flash reprogrammability, no crypto engine. | Fixed-function hub controller only - cannot implement custom PD policies, billboard class, or firmware updates post-deployment. | Choose for simple multi-port expansion where PD is secondary; not suitable for adaptive power negotiation or secure firmware ecosystems. |
Compared with STUSB4500QTR and TUSB8041RJBR, CYPD3135-32LQXQ uniquely combines field-upgradable PD 3.0 stack, hardware crypto, VCONN FETs, and analog crossbar in one 32-QFN package - enabling single-chip implementation of full-featured, certified USB-C ports with zero external PD-related ICs.
