Product details
Overview
CYPD5235-96BZXIT from Infineon Technologies (formerly Cypress) is a dual-port USB Type-C and Power Delivery 3.0 port controller featuring an Arm® Cortex®-M0 CPU (48 MHz), 128-KB flash, and integrated dual CC transceivers with RP/RD termination, VCONN FETs, and high-voltage LDO (21.5 V). It supports fast role swap, extended messaging (260-byte), and operates across –40 °C to +85 °C in a 96-ball BGA package. Used in notebook docks and Thunderbolt host systems for full PD negotiation and alternate mode routing.
For engineers reviewing the CYPD5235-96BZXIT datasheet, CYPD5235-96BZXIT pinout, CYPD5235-96BZXIT application, or CYPD5235-96BZXIT equivalent, key selection criteria include dual-port PD 3.0 compliance, integrated VCONN power delivery (1.5 W), SBU/USB analog mux switching, high-side current sensing (10-mΩ sense resistor interface), and industrial temperature support - all verified in Infineon's 002-17682 Rev. *M documentation.
Technical Context
The CYPD5235-96BZXIT implements two independent USB-PD physical layers with BMC/4b5b encoding, SOP detection, CRC generation, and collision-avoidance half-duplex communication on CC1/CC2. Each port integrates programmable RP (DFP current source) and RD (UFP termination) with dead-battery detection capability.
It embeds dual 2×2 USB HS analog muxes and dual 2×1 + 2×2 SBU crossbar switches for DisplayPort/Thunderbolt alternate mode signal routing based on plug orientation. The chip also includes an 8-bit SAR ADC with 4-input analog mux, comparator, and DAC for system monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port USB-C PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPD5225-40LQXI | Single-port variant in 40-QFN; lacks second VCONN FET, SBU crossbar, and one HS mux; 64-KB flash. | Targeted for cost-sensitive single-port applications (e.g., monitors, adapters); not suitable for dual-role dock designs. | Select only when dual-port functionality, FRS, or Thunderbolt alternate mode routing is unnecessary. |
| CYPD5236-96BZXIT | Pin-compatible upgrade with enhanced security features: secure boot, cryptographic acceleration, and anti-rollback firmware validation. | Required for applications needing NIST SP 800-193 compliance or enterprise-grade firmware integrity (e.g., government laptops, medical devices). | Choose when secure firmware lifecycle management is mandatory - adds ~$0.35/unit cost but eliminates external secure element. |
Compared with CYPD5225-40LQXI, the CYPD5235-96BZXIT delivers full dual-port autonomy and Thunderbolt-ready signal routing; versus CYPD5236-96BZXIT, it offers identical PD/USB-C functionality at lower security overhead - ideal for commercial dock platforms where certified secure boot is not mandated.

FAQ
What is the maximum VBUS voltage the CYPD5235-96BZXIT can tolerate on its VBUS_P1/P2 pins?
The CYPD5235-96BZXIT supports operation up to 21.5 V on VBUS_P1 and VBUS_P2 pins via its integrated high-voltage LDO. This allows direct connection to 20-V USB-PD sources without external regulation. Absolute maximum rating is 24 V, but sustained operation above 21.5 V may trigger OVP shutdown or degrade long-term reliability.
Does the CYPD5235-96BZXIT support USB-C audio adapter accessory mode?
No. The CYPD5235-96BZXIT does not implement Audio Adapter Accessory Mode (AAA) as defined in USB Type-C specification revision 1.4. Its analog muxes and firmware stack are optimized for USB 2.0, DisplayPort, and Thunderbolt alternate modes - not for analog audio path switching or headset detection.
Can the CYPD5235-96BZXIT operate without an external crystal or oscillator?
Yes. The device integrates a factory-trimmed internal oscillator sufficient for USB-PD BMC timing and system clocking. An external crystal is optional and only required if tighter frequency accuracy (<±0.5%) is needed for USB 2.0 HS eye diagram margin or synchronous peripheral timing.
How many GPIOs are available for custom firmware functions beyond USB-C control?
The CYPD5235-96BZXIT provides 28 general-purpose I/O pins, of which 20 are fully configurable as digital inputs/outputs, PWM, SCB (I²C/SPI/UART), or TCPWM. Eight pins are dedicated to analog functions (ADC inputs, VREF, etc.) and cannot be repurposed as GPIOs.
