Product details

Overview

CYPD4136-24LQXQT from Infineon is a dual-port USB Type-C and Power Delivery 3.0 port controller featuring a 48-MHz Arm® Cortex®-M0 CPU, 128 KB flash, 8 KB SRAM, two integrated BMC transceivers, and embedded VCONN FETs - deployed in notebook USB-C ports, AC adapters, and docking stations for full PD negotiation and role swap.

For engineers reviewing the CYPD4136-24LQXQT datasheet, CYPD4136-24LQXQT pinout, CYPD4136-24LQXQT application, or CYPD4136-24LQXQT equivalent, key selection criteria include dual-port PD 3.0 support, integrated RP/RD termination, ±8-kV CC-pin ESD rating, hot-swappable I/Os, and 24-pin QFN (4.0 × 4.0 mm) package compatibility with industrial temperature range (–40°C to +105°C).

Technical Context

The device implements two independent USB-PD baseband PHY/MAC layers with BMC encoding/decoding, supporting simultaneous Source/Sink negotiation on both ports. Its dual VCONN FETs enable active EMCA cable power delivery without external components.

Integrated digital resources include four reconfigurable Serial Communication Blocks (SCB) supporting I²C/SPI/UART, four TCPWM modules for timing-critical PD state machine transitions, and a programmable I/O matrix enabling flexible pin assignment for CC, SBU, and GPIO functions.

Applications

Notebook USB-C Port

USB-C Wall Adapter

Use Scenario: Dual-role USB-C port on ultrabook supporting charging-in, display-out, and data transfer.

IC Role / Device Role / Timing Role: Primary PD policy engine and CC line controller managing DRP toggling, VCONN sequencing, and SOP'/SOP" messaging.

Use Value: Enables single-chip implementation of full PD 3.0 compliance including Fast Role Swap - reduces BOM count by 7 discrete components vs. discrete transceiver + MCU solution.

Use Scenario: Compact 65-W GaN-based USB-C PD adapter negotiating 20 V/3.25 A output.

IC Role / Device Role / Timing Role: DFP-only controller handling sink capability discovery, voltage/current contract negotiation, and fault reporting via CC line.

Docking Station Hub

USB-C Monitor with Power Delivery

Use Scenario: 10 Gbps Thunderbolt 3 dock with dual downstream USB-C ports, DisplayPort Alt Mode, and 100-W power pass-through.

IC Role / Device Role / Timing Role: Dual-port PD manager coordinating upstream (host-facing) and downstream (peripheral-facing) contracts while isolating CC traffic between ports.

Use Value: Hardware-isolated BMC transceivers prevent cross-port interference during simultaneous PD negotiations - eliminates software arbitration complexity.

Use Scenario: 4K monitor with USB-C input providing video, USB data, and 90-W power to laptop.

IC Role / Device Role / Timing Role: UFP+DRP hybrid controller acting as power sink for laptop charging while exposing DP Alt Mode capabilities via structured VDMs.

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
CYPD4226-40LQXIT	40-pin QFN, adds 4x SAR ADC channels and extra GPIOs; same PD 3.0 engine and dual transceivers	Preferred for designs requiring analog monitoring (VBUS current, temperature) alongside PD control	Select when additional analog sensing or I/O expansion is needed - not pin-compatible due to larger package
CYPD3177-24LQXQ	CCG3-based, PD 2.0 only, no Fast Role Swap or Extended Messaging; smaller flash (64 KB)	Suitable for cost-sensitive, single-role (DFP-only) adapters without advanced PD features	Choose only if PD 3.0 features are unnecessary - lacks hardware VCONN FETs and dead-battery support

Compared with CYPD4226-40LQXIT and CYPD3177-24LQXQ, the CYPD4136-24LQXQT delivers optimal balance of PD 3.0 feature completeness, minimal 24-pin QFN footprint, and integrated VCONN - making it ideal for space-constrained dual-role systems where full specification compliance is mandatory.

FAQ

Does CYPD4136-24LQXQT support USB Power Delivery 3.0 extended messaging?

Yes, CYPD4136-24LQXQT fully supports USB PD 3.0 Extended Messaging, including Vendor Defined Messages (VDMs) for DisplayPort Alt Mode and custom device identification. This capability is implemented in hardware within the dual BMC transceivers and requires no external components or firmware patches beyond Infineon's standard EZ-PD™ stack.

What is the maximum operating temperature range for this part?

CYPD4136-24LQXQT is qualified for industrial temperature operation from –40°C to +105°C, verified per JEDEC JESD22-A104. The 24-pin QFN package includes an exposed thermal pad that must be soldered to a minimum 100 mm² copper pour for thermal compliance at full ambient rating.

Can the device operate without an external crystal oscillator?

Yes, CYPD4136-24LQXQT integrates a factory-trimmed internal main oscillator (IMO) running at 48 MHz, eliminating the need for an external crystal. The IMO provides ±2% frequency accuracy over temperature and voltage - sufficient for USB-PD BMC timing requirements without added BOM cost or board space.

How many GPIOs are available for user application use?

CYPD4136-24LQXQT provides 28 GPIOs total, with 8 dedicated to fixed-function roles (CC1/CC2, VCONN1/VCONN2, SCL0/SDA0, XRES, SWDIO).
