Product details
Overview
CYPD5235-96BZXI from Infineon Technologies (formerly Cypress) is a dual-port USB Type-C and Power Delivery 3.0 port controller featuring two integrated Type-C transceivers, 48-MHz Arm® Cortex®-M0 CPU, 128-KB flash, 12-KB SRAM, and built-in VCONN FETs, high-voltage LDO (21.5 V), and OVP/OCP on VBUS and VCONN - deployed in notebooks, docks, and Thunderbolt host systems.
For engineers reviewing the CYPD5235-96BZXI datasheet, CYPD5235-96BZXI pinout, CYPD5235-96BZXI application, or CYPD5235-96BZXI equivalent, key selection criteria include dual-port PD 3.0 compliance, dead-battery termination support, fast role swap capability, integrated SBU/USB analog muxes, and industrial temperature range (–40 °C to +85 °C) operation.
Technical Context
The CYPD5235-96BZXI implements two independent USB-PD 3.0 subsystems with BMC/4b5b encoding, SOP detection, CRC generation, and collision-avoidance PHY logic. Each port integrates programmable RP (current-source DFP) and RD (UFP) termination, plus dead-battery Rd for unpowered plug detection.
It embeds dual 2×2 USB HS analog muxes and dual 2×2 SBU crossbar switches with orientation-aware routing, enabling DisplayPort and Thunderbolt alternate mode support. The chip also integrates an 8-bit SAR ADC with 4-input analog mux, high-side current sense amplifier, and VBUS discharge FETs compliant with USB-PD detach timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB-PD Version | Complies with USB-PD 3.0 and backward-compatible with PD 2.0; supports extended messages up to 260 bytes with chunking for legacy interoperability. |
| CPU Core | Arm Cortex-M0 @ 48 MHz; enables real-time PD protocol stack execution and firmware-based policy engine control of dual ports. |
| Memory | 128-KB flash (with accelerator for near-SRAM access speed) and 12-KB SRAM; sufficient for dual-port PD firmware, USB BC 1.2/Apple charging emulation, and custom OEM logic. |
| Voltage Range | Operates from 2.75 V to 21.5 V via VSYS or VBUS inputs; integrated high-voltage LDO eliminates need for external bias rails in high-VBUS applications. |
| ESD Protection | ±8-kV contact / ±15-kV air-gap IEC 61000-4-2 Level 4C on CC, D±, and SBU pins; ensures robust hot-plug reliability in end-user environments. |

| CSP_P1/CSN_P1, CSP_P2/CSN_P2 | Current Sense Inputs | Differential inputs for high-side VBUS current sensing using external 10-mΩ shunt; enable accurate OCP and power delivery metering. |
| VBUS_P_CTRL, VBUS_C_CTRL | External PFET Gate Drivers | High-voltage-tolerant GPIOs driving external VBUS source/sink PFETs; support low-Z or high-Z output with external pull-up. |
Key Features
| Feature | Design Value |
|---|---|
| Fast Role Swap (FRS) | Enables externally powered docks to switch to bus-powered mode within <100 ms upon AC adapter removal - critical for seamless laptop-dock transitions. |
| Integrated Dead-Battery Termination | Rd resistors remain active even when MCU is unpowered, allowing charging initiation and role negotiation before system boot - essential for "cold attach" scenarios. |
| Dual SBU Crossbar Switches | Per-port 2×2 SBU routing with orientation-aware signal path selection supports DisplayPort Alt Mode without external mux ICs or layout complexity. |
| USB Charger Detection | On-chip BC 1.2 and Apple charging (source-only) detection blocks eliminate need for discrete charger ID ICs in host-side implementations. |
| Deep Sleep with FRS Wake | Enters ultra-low-power state while retaining CC line monitoring; wakes instantly on FRS signal - extends battery life in notebook sleep modes. |
Applications
| USB-C Docking Station | Thunderbolt 3/4 Host Controller |
|---|---|
|

Use Scenario: 4-port USB-C hub with independent PD contracts per port, supporting mixed sink/source configurations and independent VCONN management. IC Role / Device Role / Timing Role: Centralized dual-port PD arbiter coordinating power allocation, role swapping, and cable identification across multiple downstream ports via companion hub ICs. Use Value: Enables dynamic power budgeting and cable-aware topology management - avoids overloading upstream source and prevents unsafe VCONN backfeed. |
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 | Same CCG5 architecture but in 40-pin QFN package; single-port capable (NRND per datasheet); lacks second SBU/HS mux and one VCONN FET. | Targeted at cost-sensitive single-port applications (e.g., monitor USB-C input); not suitable for dual-role docks requiring full 2-port feature parity. | Select only if design requires single-port operation and QFN assembly compatibility; verify NRND status with Infineon for new designs. |
| CYPD5236-96BZXI | Pin-compatible upgrade with enhanced firmware support for USB-PD 3.1 EPR (Extended Power Range); identical package, pinout, and electrical specs. | Required for systems targeting >100 W (up to 240 W) delivery; maintains backward compatibility with PD 3.0 but adds EPR message handling and voltage negotiation. | Choose for future-proofing where EPR compliance is planned; no hardware change needed - firmware update suffices for migration. |
Compared with CYPD5225-40LQXI, CYPD5235-96BZXI delivers full dual-port feature parity including redundant VCONN FETs and dual SBU/HS muxes, while CYPD5236-96BZXI extends the same platform to support USB-PD 3.1 EPR without altering PCB layout or power architecture.

FAQ
Is CYPD5235-96BZXI pin-compatible with earlier CCG5 variants?
Yes - CYPD5235-96BZXI shares identical 96-ball BGA pinout and footprint with CYPD5236-96BZXI and CYPD5237-96BZXI. All three support the same power, CC, VCONN, and GPIO assignments, enabling drop-in firmware upgrades without PCB revision.
Does CYPD5235-96BZXI support USB-PD 3.1 Extended Power Range (EPR)?
No - CYPD5235-96BZXI implements USB-PD 3.0 only. EPR support requires CYPD5236-96BZXI or later, which adds firmware-level EPR message parsing, variable voltage negotiation, and updated safety timers while maintaining hardware compatibility.
What is the maximum VBUS voltage the integrated LDO can regulate?
The integrated high-voltage LDO operates up to 21.5 V input, supporting USB-PD PPS (Programmable Power Supply) profiles and legacy 20-V laptop chargers. It delivers regulated VDDD for internal analog/digital blocks without external regulators.
Can CYPD5235-96BZXI manage both upstream and downstream facing ports simultaneously?
Yes - it natively supports dual-role port (DRP) operation on both ports, enabling simultaneous UFP/DFP negotiation, Fast Role Swap, and independent VCONN control - essential for intelligent docks that act as both host and device depending on cable direction and policy.
