Product details
Overview
CYPD4136-24LQXIT 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. It supports DRP operation with integrated VCONN FETs, fast role swap, and extended data messaging for notebook, docking station, and power adapter applications.
For engineers reviewing the CYPD4136-24LQXIT datasheet, CYPD4136-24LQXIT pinout, CYPD4136-24LQXIT application, or CYPD4136-24LQXIT equivalent, key selection criteria include dual-port PD 3.0 compliance, integrated CC line ESD protection (±8 kV contact), 24-pin QFN package footprint, and support for hot-swappable I/Os on CC1/CC2 and Port 0 I²C pins.
Technical Context
The device implements two independent USB-PD Baseband PHY/MAC subsystems with dedicated BMC encoding/decoding, enabling concurrent negotiation on both Type-C ports. Each port integrates programmable current sources (RP) and pull-down resistors (RD), dead-battery termination, and ±8-kV IEC61000-4-2 ESD protection on CC pins.
Its MCU subsystem uses an Arm® Cortex®-M0 core with hardware multiplier, NVIC, WIC, and SWD debug interface, coupled with four reconfigurable Serial Communication Blocks (SCBs) supporting I²C/SPI/UART and four TCPWM modules for timing-critical PD protocol responses.

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 |
|---|---|---|---|
| CYPD4226-40LQXI | 40-pin QFN, adds 4-channel 12-bit SAR ADC and extra GPIOs; same PD 3.0 stack and dual BMC transceivers | Better suited for systems requiring analog sensing (e.g., temperature, voltage monitoring) alongside PD control | Select when additional analog inputs or I/O expansion is needed without changing firmware architecture |
| UPD350A-EZ-000 | Renesas UPD350A uses 32-bit RISC-V core, supports PD 3.0 but lacks integrated VCONN FETs and has no dead-battery termination | Requires external VCONN driver and CC line biasing circuitry; higher BOM cost and layout complexity | Choose only if RISC-V toolchain preference outweighs integration benefits and thermal footprint constraints |
Compared with CYPD4226-40LQXI, CYPD4136-24LQXIT offers identical PD functionality in a 30% smaller footprint and lower static current, while the UPD350A-EZ-000 requires external components to match basic CCG4 features, increasing design risk and board area.

FAQ
Is CYPD4136-24LQXIT pin-compatible with earlier CCG3 or CCG2 devices?
No. CYPD4136-24LQXIT uses a 24-pin QFN package with unique pin assignments for dual BMC transceivers, VCONN FET drivers, and SWD debug interface. It is not mechanically or electrically pin-compatible with CCG2 (40-pin QFN) or CCG3 (33-ball CSP) devices due to differing I/O architecture and power domain partitioning.
Does CYPD4136-24LQXIT support USB Power Delivery 3.0 Programmable Power Supply (PPS)?
Yes. The device implements full USB-PD 3.0 specification compliance, including PPS request/response handling, voltage step resolution of 20 mV, and current step resolution of 50 mA. Firmware must be configured with PPS-capable PDOs and enable extended messaging for real-time voltage/current adjustment.
What is the maximum operating frequency of the integrated oscillator?
The internal main oscillator (IMO) operates at 48 MHz and is factory-trimmed to ±2% accuracy over temperature and voltage. It serves as the primary clock source for the Cortex®-M0 core and USB-PD subsystem, eliminating need for external crystal or oscillator in most USB-C port applications.
Can CYPD4136-24LQXIT operate in dead-battery mode without external biasing?
Yes. The device integrates dedicated dead-battery termination circuitry on both CC1 and CC2 lines, enabling detection and enumeration of a connected UFP (e.g., charger) even when the host system's main supply is absent or fully discharged. No external resistors or biasing networks are required.
