Product details
Overview
CYPM1011-24LQXIT from Infineon is a USB-C Power Delivery (PD) microcontroller with Arm® Cortex®-M0 core, 64 KB Flash/8 KB SRAM, integrated USB PD 3.2 transceiver, dual-role power (DRP) support, and 2× PFET gate drivers for VBUS control - designed for compact, battery-powered USB-C DRP applications such as power banks and portable electronics.
For engineers reviewing the CYPM1011-24LQXIT datasheet, CYPM1011-24LQXIT pinout, CYPM1011-24LQXIT application, or CYPM1011-24LQXIT equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative options aligned with USB PD 3.2 DRP system design requirements.
Technical Context
The CYPM1011-24LQXIT implements a complete USB Type-C PD 3.2 physical layer with integrated Rd/Rp termination resistors and supports dual-role power negotiation via its embedded PD protocol engine. It operates across VBUS 4–21.5 V and VDDD 2.7–5.5 V, enabling direct high-voltage port management without external level-shifting.
Its MCU subsystem runs at 48 MHz, includes 2× 8-bit SAR ADCs, low-side current sense amplifier for OCP/SCP, liquid detection blocks for corrosion mitigation, and two SCB peripherals configurable as I²C/UART/SPI - all coordinated through a single-layer AHB interconnect and NVIC-based interrupt routing.

Applications
| Smart Power Bank | USB-C Cordless Tool Charger |
|---|---|
Use Scenario: Portable dual-port power bank delivering up to 20 V/3 A via USB-C PD while managing Li-ion cell balancing and thermal limits. IC Role / Device Role / Timing Role: Primary PD controller and system manager - handles PD negotiation, VBUS path control, current sensing, and user interface timing. Use Value: Single-chip integration reduces PCB area by 35% vs MCU+PD IC solution and enables certified PD 3.2 compliance without external protocol stack licensing. | Use Scenario: Cordless power tool dock that negotiates 20 V PPS profile with tool battery pack and manages fast-charge sequencing with thermal foldback. IC Role / Device Role / Timing Role: DRP-capable PD manager - initiates source mode during charging, switches to sink mode for tool firmware updates, and enforces safety timers. Use Value: Integrated low-side CSA and OCP/SCP protection eliminate need for external current-sense amplifiers and reduce failure modes in high-current charging paths. |
| Home Appliance USB-C Port | Drone Onboard Charging Hub |
Use Scenario: Vacuum cleaner with USB-C port for accessory charging and firmware updates, requiring robust ESD immunity and moisture resistance. IC Role / Device Role / Timing Role: USB-C interface controller - detects liquid ingress, triggers Corrosion Mitigation mode, and maintains PD link integrity during humid operation. Use Value: On-die liquid detection reduces field failure rate in consumer appliances exposed to cleaning fluids or condensation. | Use Scenario: Multi-battery drone docking station that charges up to three smart batteries simultaneously via independent USB-C PD ports. IC Role / Device Role / Timing Role: Central PD coordinator - arbitrates power allocation between ports, sequences charge initiation, and logs VBUS/CC telemetry for diagnostics. Use Value: Dual SCB interfaces allow concurrent communication with battery fuel gauges (I²C) and flight controller (UART), enabling synchronized charge scheduling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C PD controller with MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPM1011-40LQXI | 40-QFN package, 17 GPIOs, same core/peripherals but larger footprint and higher I/O count. | Required when more SCB interfaces, TCPWM channels, or GPIOs are needed for multi-port or sensor-rich systems. | Select for designs needing >12 GPIOs or additional SCB/TCPWM resources; not drop-in compatible due to package and pinout change. |
| STUSB4500QTR | Dedicated USB PD controller (no MCU), supports PD 3.0 only, no integrated ADC or liquid detection. | Suitable for simple source-only applications where firmware control beyond PD negotiation is unnecessary. | Choose when MCU functionality is handled externally and cost-per-function favors separation of PD control and application logic. |
Compared with CYPM1011-40LQXI, the -24LQXIT offers identical PD and MCU capability in a smaller 24-QFN package ideal for space-constrained devices; versus STUSB4500QTR, it provides full firmware programmability and integrated safety features at the cost of higher design complexity.

FAQ
Does CYPM1011-24LQXIT support USB PD 3.2 Programmable Power Supply (PPS)?
Yes, CYPM1011-24LQXIT fully supports USB PD 3.2 PPS in both source and sink roles. Its integrated 8-bit SAR ADC and low-side current sense amplifier enable real-time VBUS and current monitoring required for PPS voltage stepping and regulation, with firmware-controlled loop response meeting USB-IF PPS timing requirements.
What is the function of the Fail-Safe GPIOs (P2.2 and P2.3)?
P2.2 and P2.3 retain output state and interrupt capability during brownout, reset, or deep-sleep modes. They are hardwired to drive external PFET gate disable signals or latched fault indicators - ensuring safe VBUS disconnection even if main firmware crashes or power drops below operational threshold.
Can CYPM1011-24LQXIT operate without an external crystal?
Yes. The device includes an internal main oscillator (IMO) calibrated to ±2% accuracy over temperature and voltage, sufficient for USB full-speed device operation and PD timing. An external crystal is optional and only needed if tighter clock accuracy (<±0.25%) is required for specific UART baud rates or custom timing-critical peripherals.
How does liquid detection work on CYPM1011-24LQXIT?
Liquid detection uses dedicated analog circuitry to measure impedance between CC pins and ground. When moisture bridges the connector, impedance drops below threshold; the hardware automatically triggers Corrosion Mitigation mode - discharging VBUS, disabling PFETs, and isolating CC lines - all without CPU intervention to prevent electrochemical damage.
