Product details
Overview
CYPD4236-40LQXQ from Infineon is a dual-port USB Type-C and Power Delivery 3.0 port controller IC featuring a 48-MHz Arm® Cortex®-M0 CPU, 128 KB flash, 8 KB SRAM, two integrated BMC transceivers, and on-die RP/RD termination resistors - deployed in notebooks, power adapters, and docking stations for full PD negotiation and role swap control.
For engineers reviewing the CYPD4236-40LQXQ datasheet, CYPD4236-40LQXQ pinout, CYPD4236-40LQXQ application, or CYPD4236-40LQXQ equivalent, this device delivers verified dual-port CC channel management, integrated VCONN FETs, ±8-kV IEC61000-4-2 ESD protection on CC pins, and firmware-configurable PD policy engine for production-grade USB-C system integration.
Technical Context
The CYPD4236-40LQXQ implements two independent USB-PD Baseband PHY/MAC subsystems with dedicated BMC encoding/decoding logic, supporting full PD 3.0 message exchange including Extended Message and Fast Role Swap. Each port integrates programmable current sources (RP) and pull-down resistors (RD) for DFP/UFP/DRP detection per USB Type-C specification Rev 1.4.
Its MCU subsystem runs real-time PD policy stack via 48-MHz Cortex-M0 with hardware multiplier and NVIC, while four reconfigurable Serial Communication Blocks (SCB) support concurrent I²C (for PMIC/charger interface), SPI (for external flash), and UART (for debug/logging) - all routed through a programmable I/O matrix compatible with hot-swappable CC and I²C pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm® Cortex®-M0 @ 48 MHz - enables deterministic PD protocol timing and real-time policy execution without external timing margin. |
| Flash / SRAM | 128 KB flash + 8 KB SRAM - sufficient for dual-port PD 3.0 stack, vendor-defined policies, and field-upgradable firmware. |
| USB-PD Support | Full PD 3.0 compliance (including Extended Messages & Fast Role Swap) - required for USB-C DRP negotiation in modern adapters and docks. |
| CC Pin ESD | ±8 kV contact / ±15 kV air-gap per IEC61000-4-2 Level 4 - eliminates need for external TVS diodes on CC lines. |
| Operating Voltage | 2.7 V to 5.5 V - supports direct connection to VBUS or 3.3 V/5 V system rails without LDO overhead. |
| GPIO Flexibility | 28 GPIOs with independent 1.71–5.5 V I/O supply - allows mixed-voltage signaling with legacy PMICs, sensors, or status LEDs. |
| Package | 6.0 mm × 6.0 mm, 0.6 mm pitch, 40-pin QFN - standard footprint for thermal-aware USB-C port layout with exposed thermal pad. |
Pinout & Package
Package: 40-pin QFN (6.0 mm × 6.0 mm, 0.6 mm pitch), thermally enhanced with exposed pad. Supports –40°C to +105°C industrial temperature range.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1 / CC2 | Configuration Channel (Port 0) | Dual-purpose analog/digital pins for BMC signaling, Rp/Rd detection, and VCONN enable - hot-swappable per spec. |
| CC3 / CC4 | Configuration Channel (Port 1) | Independent CC pair for second Type-C port - enables true dual-role port control without multiplexing latency. |
| VCONN1 / VCONN2 | VCONN Power Switch Outputs | Integrated 2× FETs per port - directly power EMCA cables without external MOSFETs or gate drivers. |
| SCL0 / SDA0 | I²C Interface (Port 0) | Configurable as master/slave I²C bus - connects to charger IC, battery gauge, or system PMIC for coordinated power policy. |
| SWDIO / SWCLK | Serial Wire Debug | 2-pin JTAG-compatible debug interface - enables in-system firmware update and real-time PD stack tracing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual USB-PD BMC Transceivers | Two fully independent physical layers eliminate cross-port timing interference during simultaneous PD negotiations. |
| Integrated RP/RD Termination | On-die 5.1 kΩ RD (UFP) and programmable 10–56 kΩ RP (DFP) - removes 4 external resistors per port and improves BOM accuracy. |
| VCONN FET Integration | Dedicated 2× low-Rds(on) FETs per port - reduces solution size by 4 MOSFETs and associated gate drive circuitry. |
| Hot-Swappable CC & I²C Pins | ESD-hardened input structure with dynamic biasing - prevents glitch-induced PD reset during cable insertion/removal. |
| Programmable I/O Matrix | Runtime remapping of SCB and TCPWM functions to any GPIO - simplifies PCB routing and enables late-stage feature tuning. |
Applications

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 |
|---|---|---|---|
| CYPD4226-40LQXQ | Same die, 32 KB flash (vs. 128 KB); no PD 3.0 Extended Message support | Limited to PD 2.0 only; unsuitable for USB-C accessories requiring Vendor Defined Messages | Select when firmware footprint <32 KB and PD 3.0 features are not required. |
| STUSB4500QTR | Standalone PD controller (no MCU); requires external host MCU for policy decisions | Needs separate microcontroller for custom PD behavior - increases latency and BOM cost | Select only for simple fixed-role applications where policy logic is static and externally managed. |
Compared with CYPD4226-40LQXQ and STUSB4500QTR, the CYPD4236-40LQXQ uniquely combines full PD 3.0 stack execution, dual-port autonomy, and integrated termination/VCONN in one chip - reducing system-level latency, component count, and firmware development effort for complex DRP systems.

FAQ
What is the maximum supported USB Power Delivery revision for CYPD4236-40LQXQ?
CYPD4236-40LQXQ fully supports USB Power Delivery 3.0, including Extended Messages, Fast Role Swap, and Programmable Power Supply (PPS) negotiation. It implements the complete PD 3.0 protocol stack in firmware running on its embedded Cortex-M0 core - unlike earlier CCGx variants limited to PD 2.0 only.
Does CYPD4236-40LQXQ require an external crystal oscillator?
No. The device integrates a factory-trimmed internal main oscillator (IMO) operating at 48 MHz, eliminating the need for an external crystal or clock source. This reduces BOM cost and board area while maintaining ±2% frequency accuracy across temperature and voltage - sufficient for USB-C CC timing requirements.
How many GPIOs are available, and what voltage levels do they support?
CYPD4236-40LQXQ provides 28 general-purpose I/O pins with independent VDDIO supply (1.71–5.5 V), enabling direct interface to 1.8 V, 3.3 V, or 5 V peripherals without level shifters. All GPIOs support interrupt-on-change and configurable drive strength up to 20 mA.
Can CYPD4236-40LQXQ manage both USB-C ports simultaneously during power role swaps?
Yes. Its dual independent PD subsystems allow concurrent, asynchronous role swap execution on Port 0 and Port 1 - verified in Infineon's reference firmware with sub-100 µs arbitration latency. Each port maintains its own CC state machine, BMC transceiver, and VCONN control, ensuring no cross-port blocking during negotiation.
