Infineon Technologies CYPD8225-97BZXIT

Overview

CYPD8225-97BZXIT from Infineon is a dual-port USB Type-C and Power Delivery 3.1 port controller featuring an integrated Arm® Cortex®-M0+ core (48 MHz), 256 KB Flash, 32 KB SRAM, and native support for Extended Power Range up to 28 V. It integrates USB PD subsystems per port, VCONN FETs, 3:1 SBU muxes, VBUS provider NFET gate driver with slew-rate control and fault protection, and a high-voltage LDO (28 V). It targets notebook and desktop host applications requiring full USB-C port control with EPR compliance.

For engineers reviewing the CYPD8225-97BZXIT datasheet, CYPD8225-97BZXIT pinout, CYPD8225-97BZXIT application, or CYPD8225-97BZXIT equivalent, key selection criteria include dual-port PD 3.1 stack integration, embedded dead-battery Rd termination, hardware-controlled VBUS OVP/UVP/OCP/thermal protection, and native support for Fast Role Swap (FRS) with external load switch coordination.

Technical Context

The device implements two independent USB PD protocol engines-one per port-each with dedicated CC logic, BMC transceivers, and state machines compliant with USB PD 3.1 Rev 1.3. Its integrated analog blocks include dual 12-bit SAR ADCs, high-side VBUS current sense amplifier (5-mΩ shunt compatible), and programmable current sources for Rp (900 mA / 1.5 A / 3 A) and Rd termination.

System-level timing is managed by four TCPWM blocks (configurable as timers/counters/PWMs) and four SCBs supporting I²C/SPI/UART, enabling real-time PD messaging, policy engine execution, and host interface communication without external timing components. The integrated oscillator eliminates need for external crystal.

FAQ

Does CYPD8225-97BZXIT require an external crystal?

No. The device integrates a precision oscillator meeting ±1.5% frequency accuracy across temperature and voltage ranges, eliminating need for external crystal or clock source. This reduces BOM cost and PCB layout complexity while maintaining USB PD timing compliance for BMC encoding and decoding.

What is the maximum VBUS voltage supported for EPR operation?

CYPD8225-97BZXIT supports Extended Power Range up to 28 V on the VBUS rail without external components. Its internal HV LDO, VBUS protection comparators, and gate driver are rated for continuous 28 V operation, and it complies with USB PD 3.1 Rev 1.3 EPR specifications including 28 V/5 A (140 W) delivery.

Can CYPD8225-97BZXIT perform Fast Role Swap autonomously?

Yes, but requires coordination with an external FRS-capable load switch on the VBUS provider path. The IC generates precise timing signals and control logic for FRS, but the actual VBUS path switching must be handled by an external NFET driver meeting USB PD specification tFRS timing (<500 µs). Internal gate driver supports slew-rate control for clean transitions.

How is dead-battery operation enabled?

Dead-battery operation is enabled via the integrated high-voltage LDO, which accepts 4–28 V VBUS input and regulates down to 3.3 V for internal logic. Combined with integrated dead-battery Rd termination on CC pins, the device powers up and negotiates power even when system VSYS is at 0 V-critical for notebook "cold boot" from discharged battery states.
