Product details
Overview
CYPM1311-48LDXI from Infineon is a 48-MHz Arm® Cortex®-M0+ USB-C Power Delivery MCU with dual PD port support, 256 KB flash/32 KB SRAM, integrated 28 V VBUS NFET gate drivers, hardware crypto engine (AES-128/SHA2-256/TRNG), and 26 GPIOs in 48-QFN package. It implements USB PD 3.2, EPR up to 28 V, and supports liquid detection for rugged USB-C docking stations.
For engineers reviewing the CYPM1311-48LDXI datasheet, CYPM1311-48LDXI pinout, CYPM1311-48LDXI application, or CYPM1311-48LDXI equivalent, key selection criteria include dual-port PD controller integration, 28 V extended power range compliance, fail-safe GPIO architecture, and on-chip CAPSENSE™ for moisture-resistant connector interfaces.
Technical Context
The CYPM1311-48LDXI integrates two independent USB PD subsystems with baseband transceivers, each driving a pair of NFET gate drivers with slew-rate control for inrush current limiting in both source and sink configurations. Its 48-MHz Cortex®-M0+ core executes PD policy firmware from 256 KB flash while managing real-time analog sensing via dual 8-bit SAR ADCs and one 12-bit SAR ADC.
It features eight reconfigurable SCB blocks (I²C/SPI/UART), eight TCPWM modules, and a dedicated hardware crypto engine supporting AES-128, SHA2-256, and TRNG for secure boot and signed firmware updates - all operating across VSYS (2.8–5.5 V) and VBUS (4–28 V) supply domains with independent 1.71–5.5 V I/O signaling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C Power Delivery MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPM1322-97BZXI | 97-BGA package, 50 GPIOs, integrated 3:1 SBU analog muxes, CAPSENSE™ sigma-delta CSD block | Required for DisplayPort/Thunderbolt Alt Mode support and higher I/O density in compact form factors | Select when SBU routing or >26 GPIOs are needed; not pin-compatible with CYPM1311-48LDXI |
| STUSB4500QTR | Dedicated USB PD controller (no MCU), 28 V VBUS, no flash/SRAM/crypto, 20-pin TSSOP | Used only for basic PD policy offload - requires external microcontroller for application logic | Choose only for cost-sensitive, non-programmable PD implementations where firmware customization is unnecessary |
Compared with CYPM1311-48LDXI, the CYPM1322-97BZXI adds SBU muxing and I/O scalability at the cost of larger footprint and assembly complexity, while the STUSB4500QTR provides minimal PD control without MCU capability - making CYPM1311-48LDXI optimal for programmable, dual-port, security-aware USB-C systems.
