Product details

Overview

CYPD6127-48LQXI from Infineon is a single-port USB Type-C and Power Delivery (PD) 3.0 port controller with integrated Arm® Cortex®-M0 MCU (48 MHz, 64-KB flash, 96-KB ROM), VBUS provider load switch (5 V/3 A), true random number generator (TRNG), and full CC/SBU/DP/DM analog mux support. It serves as the central control IC for USB-C ports in notebooks and desktops, managing power role negotiation, dead-battery detection, VCONN cable power, and BMC communication.

For engineers reviewing the CYPD6127-48LQXI datasheet, CYPD6127-48LQXI pinout, CYPD6127-48LQXI application, or CYPD6127-48LQXI equivalent, this device is selected for its integrated high-voltage protection on CC/SBU pins (up to 24 V tolerance), slew-rate-controlled VBUS gate driver, hardware-configurable OVP/UVP/OCP/SCP/RCP, and native support for Fast Role Swap (FRS) and extended data messaging in PD 3.0 systems.

Technical Context

The CYPD6127-48LQXI implements a complete USB-C port controller stack in one die: dual CC line transceivers with Rp/Rd termination, integrated VCONN FETs (2×), SBU pass-through switches with VBUS short-circuit protection, and a dedicated USB PD subsystem with BMC PHY and protocol engine. Its MCU subsystem runs certified PD firmware from ROM and supports runtime reconfiguration of four SCBs (I2C/SPI/UART).

It operates across VSYS (2.75–5.5 V) and VBUS (4–21.5 V), features an on-die 21.5-V LDO for dead-battery mode, and includes a high-side current sense amplifier calibrated for 5-mΩ shunt measurement on the VBUS provider path - enabling precise 3-A current monitoring without external components.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB Type-C port controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYPD6127-64BZXI	Dual-port variant in 96-ball BGA; adds second independent USB-C port controller block and extra SCB/SCB resources	Required for systems needing two fully independent Type-C ports (e.g., dual-display docking stations)	Select only if dual-port functionality and BGA layout are acceptable; not pin-compatible
TPS65988DHAR	Texas Instruments part with integrated 20-V, 5-A VBUS switch; lacks embedded MCU and requires external firmware host	Used in host-processor-based designs where main SoC handles PD policy stack	Choose when leveraging existing Linux/Windows PD stack; avoid if standalone port control without host CPU is needed

Compared with CYPD6127-48LQXI, the CYPD6127-64BZXI adds dual-port capability at the cost of larger footprint and BGA assembly complexity, while TPS65988DHAR shifts PD intelligence to host software - making CYPD6127-48LQXI optimal for hostless, space-constrained, or security-sensitive embedded USB-C endpoints.

FAQ

What is the maximum VBUS voltage the CYPD6127-48LQXI can tolerate on its CC pins?

The CYPD6127-48LQXI integrates hardware-level protection that tolerates accidental shorts between CC1/CC2 and VBUS up to 24 V - verified per datasheet Section 7.1 (Absolute Maximum Ratings) and functional diagram on page 4. This eliminates need for external TVS diodes in most notebook and dock designs.

Does the device support USB Power Delivery 3.0 Fast Role Swap (FRS) without host processor intervention?

Yes. FRS execution is handled entirely in hardware: upon detecting BMC FRS message, the device autonomously disables the consumer NFET gate driver (VBUS_C), enables the internal VBUS provider switch, and reconfigures CC line terminations - all within ≤80 µs, independent of the Cortex-M0 firmware state.

Can the CYPD6127-48LQXI operate when the system VSYS rail is absent (e.g., dead battery condition)?

Yes. The integrated 21.5-V LDO powers the USB-C detection circuitry directly from VBUS, enabling Rd termination activation, CC line monitoring, and initial PD handshake - allowing enumeration and VCONN power delivery even when VSYS is below 2.75 V or unpowered.

How many serial interfaces does the device support simultaneously, and what protocols are configurable?

The device includes four Serial Communication Blocks (SCBs), each independently configurable at runtime as I2C master/slave, SPI master/slave, or UART TX/RX. All four can operate concurrently - e.g., one I2C for PMIC control, one SPI for flash logging, two UARTs for debug and sensor telemetry - with no shared clock or bus contention.
