Product details
Overview
CYPM1211-40LQXI 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 for VBUS control, 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 applications including USB-C power adapters and docking stations.
For engineers reviewing the CYPM1211-40LQXI datasheet, CYPM1211-40LQXI pinout, CYPM1211-40LQXI application, or CYPM1211-40LQXI equivalent, key selection criteria include integrated PD protocol stack execution, 20 GPIOs with OVT support, full-speed USB device + Billboard Class, ±8-kV contact ESD on CC/SBU/USB pins, and dual gate driver timing specs for external VBUS FET switching.
Technical Context
The CYPM1211-40LQXI implements a dedicated USB PD subsystem with hardware BMC encoding/decoding, fast role swap (FRS), and extended messaging-offloading protocol handling from the Cortex-M0 core. Its dual independent NFET gate drivers support synchronous high-side/low-side VBUS switching with programmable dead-time control and OCP/OVP fault reporting via dedicated interrupt lines.
It integrates a full-speed USB 2.0 device controller with Billboard Class support for vendor-defined status reporting during PD negotiation failures, and a hardware crypto block enabling secure firmware updates and certificate-based authentication without software overhead. The 48 MHz clock derives from an internal IMO, eliminating external crystal requirements.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPM1211-42LQXI | Same die, 42-ball CSP package (2.63 × 3.18 mm) - smaller footprint but no exposed thermal pad | Space-constrained portable accessories where board area is prioritized over thermal dissipation | Select for ultra-thin designs; derate power delivery capability by 15% due to reduced thermal mass |
| CYPM1212-40LQXI | Same package but with 256 KB flash / 32 KB SRAM and 7 SCBs - higher memory and peripheral count | Systems requiring dual PD ports or complex firmware with BLE coexistence and advanced diagnostics | Select only if >128 KB flash is required; otherwise CYPM1211-40LQXI offers optimal cost/performance balance |
Compared with CYPM1211-42LQXI, the -40LQXI offers superior thermal performance and easier reworkability; compared with CYPM1212-40LQXI, it delivers identical PD functionality at lower cost and power, making it ideal for single-port industrial adapters and docks.

FAQ
Does CYPM1211-40LQXI support USB PD 3.1 Extended Power Range (EPR)?
No. CYPM1211-40LQXI implements USB PD 3.0 specification only, supporting up to 21.5 V VBUS and 100 W power delivery. It lacks the 28 V VBUS rating, enhanced BMC timing, and EPR-specific message structures required for PD 3.1 EPR compliance. For EPR support, Infineon's CYPM1213-S3 series is required.
Can the integrated gate drivers directly drive 100 V-rated GaN FETs?
No. The GDRV1H/GDRV1L and GDRV2H/GDRV2L outputs are rated for 21.5 V maximum VBUS and drive logic-level NFETs with ≤20 V gate threshold. Driving 100 V GaN devices requires external level-shifting gate drivers or discrete high-side drivers compatible with the CYPM1211's 1.2 A peak output current and 50 ns propagation delay.
Is the hardware crypto engine certified to FIPS 140-2 or Common Criteria?
The crypto block implements NIST-approved algorithms (AES-128/192/256, SHA2-256) but is not individually FIPS 140-2 or Common Criteria certified. Certification applies only when integrated into a complete system meeting evaluation assurance level (EAL) requirements. Infineon provides algorithm validation reports (CAVP) for standalone cryptographic operations.
What debug interfaces are supported for firmware development?
CYPM1211-40LQXI supports SWD (Serial Wire Debug) via dedicated SWDIO and SWCLK pins, enabling full JTAG-style debugging, flash programming, and real-time trace using ModusToolbox™ IDE and compatible debug probes (e.g., KitProg3). No UART bootloader is factory-enabled; firmware updates require SWD access or pre-programmed USB DFU mode.
