Product details
Overview
CYPM1111-40LQXIT from Infineon is a USB-C Power Delivery (PD) microcontroller integrating an Arm® Cortex®-M0 CPU, full USB PD 3.0 transceiver, dual PFET gate drivers, 128 KB flash/12 KB SRAM, and VBUS protection up to 21.5 V. It supports DRP operation, Fast Role Swap, and legacy charging (BC 1.2, Apple), targeting embedded USB-C power adapters and docking stations.
For engineers reviewing the CYPM1111-40LQXIT datasheet, CYPM1111-40LQXIT pinout, CYPM1111-40LQXIT application, or CYPM1111-40LQXIT equivalent, key selection criteria include integrated PD PHY compliance, 40-QFN package compatibility, VBUS OVP/UVP/OCP/SCP/RCP support, and fail-safe I/O for industrial USB-C port controllers.
Technical Context
The CYPM1111-40LQXIT implements a dedicated USB PD physical layer with integrated RP/RD termination, dead-battery RD, and VCONN FETs-enabling full Type-C UFP/DFP/DRP functionality without external resistors or level shifters. Its dual 24-V-tolerant PFET gate drivers directly control high-side VBUS provider and consumer paths.
It features four reconfigurable SCB peripherals (I²C/UART/SPI), two TCPWM blocks for protocol timing, and hardware-controlled VBUS protection with 5-mΩ current sense amplifier. The 17 GPIOs include two fail-safe pins tied to SCB0 for robust communication during fault conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPM1211-40LQXI | Same PMG1-S1 family but adds integrated 12-bit SAR ADC and crypto block (AES-128, SHA2-256, TRNG) | Required for secure firmware updates or analog sensor integration (e.g., temperature monitoring in adapters) | Select when cryptographic authentication or higher-resolution analog sensing is mandatory |
| STUSB4500QTR | Dedicated USB PD controller (no MCU); supports PD 3.0 but lacks programmable firmware, flash, or GPIO | Suitable only for fixed-function PD implementations without custom logic or multi-protocol support | Select only for cost-sensitive, non-programmable PD sink/source designs with no firmware requirements |
Compared with CYPM1211-40LQXI, CYPM1111-40LQXIT offers lower BOM cost and smaller code footprint where crypto or 12-bit ADC are unnecessary; versus STUSB4500QTR, it provides full firmware extensibility and integrated MCU control at the expense of higher design complexity.

FAQ
What USB PD specification versions does CYPM1111-40LQXIT support?
CYPM1111-40LQXIT fully supports USB PD 3.0, including Fast Role Swap (FRS), Extended Data Messaging (EDM), and Programmable Power Supply (PPS) negotiation. It implements the complete BMC physical layer with integrated RP/RD termination and VCONN FETs, enabling native compliance without external transceivers or resistors.
Does CYPM1111-40LQXIT include hardware-based VBUS protection?
Yes - it integrates dedicated hardware comparators for VBUS overvoltage (OVP), undervoltage (UVP), overcurrent (OCP), short-circuit (SCP), and reverse-current (RCP) protection. These operate independently of the CPU and trigger sub-10 µs shutdown of PFET drivers, ensuring robust fault containment without firmware dependency.
Can CYPM1111-40LQXIT operate with zero VBUS voltage (dead battery mode)?
Yes - it includes an integrated 5.1 kΩ RD resistor and a high-voltage LDO that operates up to 21.5 V, allowing the device to power its internal logic from VSYS while detecting and negotiating on the CC line even when VBUS is at 0 V, enabling full USB-C enumeration and firmware boot from dead-battery conditions.
How many configurable serial interfaces does CYPM1111-40LQXIT provide?
CYPM1111-40LQXIT includes four Serial Communication Blocks (SCBs), each reconfigurable at runtime as I²C, SPI, or UART. Two SCB instances support full-speed USB 2.0 Billboard class functionality, and SCB0 pins are designated as fail-safe I/O, retaining I²C operation during VSYS brownout events.
