Infineon Technologies CYPD8225-97BZXI

Overview

CYPD8225-97BZXI from Infineon is a dual-port USB Type-C and Power Delivery (PD) 3.1 port controller with integrated Arm® Cortex®-M0+ core (48 MHz), 256 KB Flash, 32 KB SRAM, and native support for Extended Power Range (EPR) up to 28 V. It integrates dual CC line transceivers, two VCONN FETs, 3:1 SBU muxes per port, VBUS provider NFET gate driver with slew-rate control and fault protection, and high-voltage LDO (28 V) for dead-battery operation - deployed in notebooks and desktops requiring robust, single-chip PD port control.

For engineers reviewing the CYPD8225-97BZXI datasheet, CYPD8225-97BZXI pinout, CYPD8225-97BZXI application, or CYPD8225-97BZXI equivalent, key selection criteria include dual-port EPR compliance, integrated Rp/Rd termination, hardware-controlled VBUS protection (OVP/UVP/OCP/SCP), and native FRS-enabling architecture without external clock or discrete termination components.

Technical Context

The CYPD8225-97BZXI implements two independent USB PD subsystems-one per Type-C port-with full PD 3.1 protocol stack execution on its Cortex-M0+ core. Each port features dedicated CC logic, integrated Rd (UFP) and programmable Rp (DFP: 900 mA / 1.5 A / 3 A), and hardware-accelerated dead-battery Rd termination.

Its analog subsystem includes a VBUS high-side current sense amplifier calibrated for 5-mΩ shunt, slew-rate-controlled VBUS NFET gate driver, and integrated 12-bit SAR ADC for system monitoring. The device operates across VSYS (2.8–5.5 V) and direct VBUS (4–28 V), enabling native EPR support without level-shifting or external regulators.

FAQ

Does CYPD8225-97BZXI support USB PD 3.1 Extended Power Range without external components?

Yes. The device natively supports up to 28 V EPR operation using its integrated high-voltage LDO and VBUS gate driver - no external voltage translators, level shifters, or termination resistors are required. This is confirmed in Section 1.1 of the official Infineon datasheet (002-33920 Rev. *G), which states EPR support "without the need of any external components."

What is the function of the VBUS_SENSEx pins?

VBUS_SENSEx pins provide differential inputs to the integrated high-side current sense amplifier, optimized for use with a 5-mΩ shunt resistor on the VBUS provider path. They enable real-time current measurement, overcurrent detection, and dynamic load profiling - all handled autonomously by hardware without CPU intervention.

Can CYPD8225-97BZXI operate when the system VSYS supply is absent?

Yes. Its integrated 28-V LDO allows full functionality-including CC line biasing, Rp/Rd termination, VCONN delivery, and PD messaging-even when VSYS is 0 V or below 2.8 V. This enables true dead-battery charging and port enumeration before system power-on, as verified in Section 2.2.1 of the datasheet.

Is Fast Role Swap (FRS) supported in hardware or firmware?

FRS is implemented in dedicated hardware within the USB PD subsystem, enabling sub-10 ms response time. However, external FRS-capable load switches are required on the VBUS provider path to meet USB PD specification timing - a requirement explicitly noted in the datasheet's Feature section and Figure 5-1 application diagram.
