Product details
Overview
CYPM1111-40LQXI 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 protocols (BC 1.2, Apple), targeting embedded USB-C power adapters and multi-port PD hubs.
For engineers reviewing the CYPM1111-40LQXI datasheet, CYPM1111-40LQXI pinout, CYPM1111-40LQXI application, or CYPM1111-40LQXI equivalent, key selection criteria include integrated CC line HV protection, slew-rate-controlled VBUS PFET drivers, hardware-based OVP/UVP/OCP/SCP/RCP, and fail-safe I2C pins for robust Type-C port control in industrial-grade (-40°C to +85°C) designs.
Technical Context
The CYPM1111-40LQXI implements a dedicated USB PD physical layer with integrated RP/RD termination, dead-battery RD, and VCONN FETs - all compliant with USB PD 3.0 and supporting Extended Data Messaging (EDM). Its dual 24-V-tolerant PFET gate drivers enable independent high-side switching on provider and consumer paths.
It features four reconfigurable Serial Communication Blocks (SCBs) supporting I²C/UART/SPI, two TCPWM blocks for timing-critical PD protocol responses, and a 12-bit-capable current sense amplifier measuring across 5-mΩ shunts. The 16 KB SROM includes boot and user firmware space to preserve flash endurance.

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 | Arm® Cortex®-M0+ core, 256 KB flash, 32 KB SRAM, 2× NFET gate drivers, 28 V VBUS rating | Supports higher-power (140 W+) applications requiring dual-role PD with extended voltage margin and crypto acceleration | Select when needing AES-128/SHA2-256, TRNG, or >21.5 V VBUS tolerance - not drop-in compatible due to driver type and memory map |
| STUSB4500QTR | Dedicated USB PD controller (no MCU), 48-pin QFN, 21 V VBUS, no flash/SRAM, only PD policy engine | Used in cost-sensitive, fixed-function chargers where firmware customization is unnecessary | Select only if application requires minimal BOM and no custom firmware - lacks MCU capability, GPIO, or analog peripherals |
Compared with CYPM1111-40LQXI, CYPM1211-40LQXI offers enhanced security and voltage headroom but requires redesign for NFET drive and crypto integration; STUSB4500QTR provides lower-cost PD control but removes all programmability and system-level intelligence.

FAQ
What USB PD specifications does CYPM1111-40LQXI support?
CYPM1111-40LQXI fully supports USB PD 3.0 including Fast Role Swap (FRS), Extended Data Messaging (EDM), and Programmable Power Supply (PPS) negotiation. It implements mandatory physical layer functions: RP/RD termination, dead-battery RD, VCONN power, and CC line high-voltage protection per USB Type-C specification revision 2.1.
Does CYPM1111-40LQXI require an external crystal oscillator?
No. CYPM1111-40LQXI integrates a precision internal oscillator (IMO) capable of generating stable 48 MHz system clock without external crystal or resonator. This reduces BOM cost and board area while maintaining USB PD timing compliance for packet transmission and FRS response windows.
Can CYPM1111-40LQXI operate in dead-battery mode?
Yes. Its integrated high-voltage LDO operates from VBUS (4–21.5 V) to generate VSYS, enabling full functionality-including CC line detection and PD negotiation-even when the system battery is fully discharged (0 V). This meets USB Type-C dead-battery requirements for downstream-facing ports.
How many GPIOs are available, and which are fail-safe?
CYPM1111-40LQXI provides 17 GPIOs in its 40-QFN package, including 2 dedicated fail-safe pins (SCB0_SDA and SCB0_SCL). These retain I²C functionality down to VSYS = 1.7 V, ensuring host communication remains active during brownout conditions common in unregulated adapter designs.
