Product details
Overview
CYPM1311-48LDXIT from Infineon is a 32-bit Arm® Cortex®-M0+ USB-C Power Delivery MCU with 256 KB flash, 32 KB SRAM, dual USB PD ports supporting 28 V EPR, integrated NFET gate drivers, and hardware crypto (AES-128/SHA2-256/TRNG). It serves as the central PD controller and system manager in high-voltage USB-C source/sink applications such as portable power banks and docking stations.
For engineers reviewing the CYPM1311-48LDXIT datasheet, CYPM1311-48LDXIT pinout, CYPM1311-48LDXIT application, or CYPM1311-48LDXIT equivalent, key selection criteria include dual PD port support, 28 V VBUS tolerance, on-chip crypto for secure firmware updates, and 48-QFN package compatibility with legacy PMG1-S3 designs.
Technical Context
The CYPM1311-48LDXIT implements two independent USB PD 3.2 baseband transceivers with configurable VBUS OVP/OCP/SCP/RCP protection and slew-rate-controlled NFET gate drivers for both provider and consumer paths. Its analog subsystem includes two 8-bit SAR ADCs and one 12-bit SAR ADC, plus CAPSENSE™ sigma-delta blocks with SmartSense auto-tuning.
Digital resources comprise seven SCB blocks (I²C/SPI/UART), eight TCPWMs, DMA support, and a programmable I/O matrix enabling any GPIO to serve as CAPSENSE™, analog input, or digital interface - all operating across 1.71–5.5 V I/O voltage range with fail-safe pins.

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 |
|---|---|---|---|
| CYPM1321-97BZXI | 97-BGA package, 50 GPIOs, 2× SBU analog muxes, CAPSENSE™ CSD only (no CSD+CSX) | Supports DisplayPort/Thunderbolt alternate modes via integrated SBU muxes; higher pin count enables complex multi-peripheral docks. | Select when SBU switching and ≥50 GPIOs are required; not pin-compatible with 48-QFN footprint. |
| CYPM1211-40LQXI | PMG1-S1 variant: Cortex-M0, 128 KB flash, 12 KB SRAM, single PD port, PFET drivers only, no crypto engine | Targeted for cost-sensitive single-port adapters without EPR or secure firmware needs. | Select only for legacy non-EPR, non-crypto applications where BOM cost outweighs future-proofing. |
Compared with CYPM1321-97BZXI, CYPM1311-48LDXIT offers identical feature set in compact 48-QFN but lacks SBU muxes and has fewer GPIOs; versus CYPM1211-40LQXI, it adds EPR support, crypto, dual PD, and M0+ performance - making it the minimum viable upgrade path for next-gen USB-C accessories.

CYPM1311-48LDXIT supports VBUS up to 28 V, enabling compliance with USB PD 3.1 Extended Power Range (EPR) specifications. Its internal VBUS sense circuitry scales and conditions signals for direct ADC measurement, and its integrated NFET gate drivers are rated for 28 V operation with programmable slew rate control to manage inrush current.
Does CYPM1311-48LDXIT include hardware cryptographic acceleration?
Yes, CYPM1311-48LDXIT integrates a dedicated hardware crypto engine supporting AES-128 encryption/decryption, SHA2-256 hashing, and a true random number generator (TRNG). This enables secure boot verification and signed firmware updates per USB PD security guidelines, eliminating reliance on software-only crypto that impacts real-time PD negotiation timing.
How many USB PD ports does CYPM1311-48LDXIT support, and what roles do they operate in?
CYPM1311-48LDXIT supports two independent USB PD ports, each configurable as Dual-Role Port (DRP) - meaning either port can act as Source, Sink, or DRP depending on cable and partner negotiation. Both ports implement full USB PD 3.2 baseband transceivers, VBUS protection (OVP/OCP/SCP/RCP), and dedicated NFET gate drivers for high-side VBUS switching.
Is CAPSENSE™ supported on CYPM1311-48LDXIT, and what type is implemented?
Yes, CYPM1311-48LDXIT includes CAPSENSE™ sigma-delta (CSD) capacitive sensing with SmartSense auto-tuning and >5:1 signal-to-noise ratio.
