Product details
Overview
CYPM1011-24LQXI from Infineon is a USB-C Power Delivery (PD) microcontroller integrating an Arm® Cortex®-M0 CPU, USB PD 3.2 transceiver, dual PFET gate drivers, 64 KB Flash/8 KB SRAM, and liquid detection circuitry - designed for DRP (dual-role power) operation on a single Type-C port in portable power banks and smart speakers.
For engineers reviewing the CYPM1011-24LQXI datasheet, CYPM1011-24LQXI pinout, CYPM1011-24LQXI application, or CYPM1011-24LQXI equivalent, key selection criteria include VBUS tolerance (4–21.5 V), integrated Rd/Rp termination, ±8-kV CC-pin ESD rating, fail-safe GPIO support, and corrosion mitigation capability for moisture-prone USB-C interfaces.
Technical Context
The CYPM1011-24LQXI implements a complete USB PD 3.2 physical layer with integrated Rp/Rd resistors and CC line monitoring logic, enabling autonomous DRP role swapping without host MCU intervention. Its dedicated PD subsystem handles BMC decoding, policy engine execution, and VBUS fault response independently of the Cortex-M0 core.
It features two high-side PFET gate drivers rated for 21.5 V VBUS operation, low-side current sense amplifier for OCP/SCP, and hardware-level liquid detection with Corrosion Mitigation mode activation - all operating within –40°C to +105°C industrial temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C Power Delivery controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPM1011-40LQXI | Same core and PD subsystem, but 40-QFN package with 17 GPIOs and 4 SCBs | Requires more PCB area; supports additional UART/I2C peripherals for complex system integration | Select when extra communication interfaces or GPIO count is required beyond 12 pins |
| CYPD3177-40LQXIT | Legacy CCG3-based PD controller (no integrated MCU); 40-QFN; supports PD 3.0 only | Lacks Arm Cortex-M0, flash, and liquid detection - requires external microcontroller for custom logic | Select only for cost-sensitive, fixed-function PD source/sink where firmware extensibility is unnecessary |
Compared with CYPM1011-40LQXI and CYPD3177-40LQXIT, CYPM1011-24LQXI uniquely balances minimal footprint, integrated MCU capability, and corrosion-aware USB-C interface - making it optimal for space-constrained, firmware-defined PD endpoints requiring field resilience.

FAQ
Does CYPM1011-24LQXI support USB PD 3.2 Extended Power Range (EPR)?
No. CYPM1011-24LQXI supports USB PD 3.2 up to 21.5 V VBUS and 5 A current, compliant with USB PD Revision 3.2 v1.3, but does not implement EPR (≥28 V). Its VBUS OVP threshold is fixed at 21.5 V, and it lacks the 28 V-rated gate drivers or EPR-specific BMC encoding required for EPR negotiation.
Can CYPM1011-24LQXI operate without an external crystal?
Yes. It integrates an Internal Main Oscillator (IMO) running at 48 MHz, fully sufficient for USB PD timing, BMC decoding, and MCU operation. An external crystal is optional and only needed if tighter frequency accuracy (<±0.25%) is required for specific USB audio or timing-critical applications.
What is the function of the two Fail-Safe GPIOs (P2.2 and P2.3)?
P2.2 and P2.3 retain drive capability and interrupt responsiveness during brownout, reset, or deep-sleep modes. They are intended for critical safety functions such as initiating VBUS discharge FET activation or asserting hardware fault signals - ensuring deterministic behavior even under power instability.
Is liquid detection supported on both CC1 and CC2 pins?
Yes. The hardware liquid detection block monitors both CC1 and CC2 pins simultaneously using dedicated comparators and charge-transfer sensing. Detection triggers Corrosion Mitigation mode, which disables VBUS FETs and places the port in a safe, high-impedance state until dry conditions are confirmed.
