Product details
Overview
CYPM1211-40LQXIT from Infineon is a USB-C Power Delivery (PD) microcontroller integrating an Arm® Cortex®-M0 CPU, USB PD 3.0 BMC transceiver, dual NFET gate drivers, 128 KB flash/8 KB SRAM, and hardware crypto engine (AES-128/192/256, SHA2-256). It supports one DRP port with 4–21.5 V VBUS operation and operates across –40°C to +105°C in industrial USB-C power adapters and docking stations.
For engineers reviewing the CYPM1211-40LQXIT datasheet, CYPM1211-40LQXIT pinout, CYPM1211-40LQXIT application, or CYPM1211-40LQXIT equivalent, key selection criteria include integrated PD protocol stack execution, dual VBUS FET gate drive capability, USB Billboard Class support, hardware-based OVP/UVP/OCP, and 20 GPIOs with 1.71–5.5 V I/O voltage flexibility.
Technical Context
The CYPM1211-40LQXIT implements a full USB PD 3.0 protocol stack in firmware running on its 48 MHz Cortex-M0 core, with dedicated hardware BMC transceiver and dead-battery detection logic. Its PD subsystem handles structured VDMs, fast role swap, and extended messaging without host CPU intervention.
Dual independent NFET gate drivers support high-side and low-side VBUS switching configurations with programmable slew rate control and fault reporting via dedicated interrupt pins. The integrated crypto block accelerates authentication for USB PD certification and secure firmware updates using AES-128/192/256 and SHA2-256.

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 |
|---|---|---|---|
| CYPM1211-42LQXI | Same silicon die, 42-ball CSP package (2.63 × 3.18 mm, 0.4 mm pitch) - smaller footprint but no exposed thermal pad | Used where board space is constrained and thermal load is lower (e.g., thin client docks) | Select when PCB area is critical and thermal dissipation ≤1.2 W; requires microvias and tighter assembly tolerances |
| CYPM1212-40LQXI | Enhanced variant with 256 KB flash/32 KB SRAM, 26 GPIOs, and 7 TCPWM blocks - no crypto engine | Targeted at non-certified PD applications needing larger firmware space and more PWM channels (e.g., motor-driven USB hubs) | Select only if crypto authentication is unnecessary and additional memory/peripherals justify higher cost and larger code base |
Compared with CYPM1211-42LQXI, the -40LQXIT offers superior thermal performance via QFN thermal pad and easier reworkability; compared with CYPM1212-40LQXI, it trades flash/SRAM capacity for mandatory USB-IF certification readiness via hardware crypto acceleration.

FAQ
Does CYPM1211-40LQXIT support USB PD 3.1 Extended Power Range (EPR)?
No. CYPM1211-40LQXIT implements USB PD 3.0 specification only, with maximum VBUS support of 21.5 V. It does not support EPR's 28 V or 48 V profiles, nor the new PRS (Power Role Swap) timing requirements introduced in PD 3.1. Firmware updates cannot extend this limitation due to hardware BMC transceiver and gate driver voltage constraints.
Can the integrated gate drivers directly drive 100 V-rated SiC MOSFETs?
No. The gate drivers are rated for 21.5 V VBUS max and designed for logic-level NFETs with VGS ≤ 12 V. Driving 100 V SiC devices would require level-shifting, isolated gate drivers, and external protection circuitry - the internal drivers lack the voltage isolation and dV/dt immunity needed for high-voltage SiC switching.
Is the hardware crypto engine FIPS 140-2 certified?
No. The crypto engine implements AES-128/192/256 and SHA2-256 per NIST SP 800-38A/800-56A/800-56C standards, but Infineon has not submitted CYPM1211-40LQXIT for FIPS 140-2 validation. It meets USB-IF certification requirements for PD authentication but is not approved for U.S. federal cryptographic modules.
What is the minimum supported VBUS voltage for dead-battery detection?
The dead-battery detection circuit operates down to 0 V VBUS input, enabling enumeration and VCONN supply even when the attached device battery is fully depleted. This functionality is implemented in analog hardware and does not require MCU wake-up or firmware intervention - confirmed in Section 2.4 of the datasheet Rev. *D.
