Product details
Overview
CYPM1322-97BZXIT from Infineon is a 32-bit Arm® Cortex®-M0+ USB-C Power Delivery MCU with dual PD ports, 256 KB flash/32 KB SRAM, 28 V VBUS rating, integrated NFET gate drivers, and hardware crypto (AES-256, SHA2-256, TRNG). It implements USB PD 3.2, EPR support, CAPSENSE™, liquid detection, and 50 GPIOs in a 97-ball BGA package for high-reliability dock and accessory power control.
For engineers reviewing the CYPM1322-97BZXIT datasheet, CYPM1322-97BZXIT pinout, CYPM1322-97BZXIT application, or CYPM1322-97BZXIT equivalent, key selection criteria include dual-port PD stack execution, 28 V extended power range compliance, VBUS discharge capability, integrated SBU analog muxes for DisplayPort/Thunderbolt alternate modes, and fail-safe GPIO architecture for safety-critical USB-C systems.
Technical Context
The CYPM1322-97BZXIT integrates two independent USB PD subsystems-each with baseband transceivers, VBUS NFET gate drivers, slew-controlled switching, and full USB PD 3.2 protocol stack support-including Extended Power Range (EPR) up to 28 V. Its dual-port architecture enables simultaneous source/sink negotiation on separate Type-C interfaces without external arbitration.
It features a dedicated hardware crypto engine (AES-256, SHA2-256, TRNG) enabling secure boot and signed firmware updates, plus CAPSENSE™ sigma-delta with SmartSense auto-tuning for robust touch and liquid detection on connector housings. The 12-bit SAR ADC and dual opamps support real-time VBUS monitoring and analog sensor interfacing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port USB-C PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPM1321-97BZXIT | Same 97-BGA package and dual-port PD architecture but with 128 KB flash/12 KB SRAM and no hardware crypto engine | Lacks AES/SHA2/TRNG-unsuitable for secure firmware update or certified bootloader implementations | Select when cost-sensitive designs omit security requirements and firmware footprint remains under 128 KB |
| CYPM1311-48LDXI | 48-QFN package variant with single PD port, 256 KB flash/32 KB SRAM, and same crypto engine-but only 26 GPIOs and no SBU analog muxes | Supports only one USB-C port and lacks DisplayPort/Thunderbolt alternate mode routing capability | Select for compact single-port accessories where board space limits BGA use and alternate modes are not required |
Compared with CYPM1321-97BZXIT and CYPM1311-48LDXI, CYPM1322-97BZXIT uniquely delivers dual-port EPR support, hardware crypto, and integrated SBU analog muxes in a single 97-BGA package-making it the only option for secure, multi-function docks requiring DisplayPort Alt Mode and 240 W power delivery.

FAQ
What USB PD specification versions does CYPM1322-97BZXIT support?
CYPM1322-97BZXIT fully supports USB PD 3.2, including Programmable Power Supply (PPS) and Extended Power Range (EPR) up to 28 V. It implements the complete PD protocol stack in ROM (96 KB) and supports all mandatory and optional PD messages defined in the USB-IF PD 3.2 specification, with hardware acceleration for BMC decoding and CRC validation.
Does CYPM1322-97BZXIT require an external crystal for USB operation?
No. CYPM1322-97BZXIT integrates a factory-trimmed 48 MHz IMO (Internal Main Oscillator) that meets USB full-speed device timing requirements (±0.25% accuracy). An external crystal is optional and only needed if tighter frequency stability (<±0.1%) is required for custom USB audio or isochronous applications.
How is liquid detection implemented on CYPM1322-97BZXIT?
Liquid detection uses dedicated CAPSENSE™ sigma-delta (CSD) channels with self-calibrating baseline tracking. Electrodes mounted near the USB-C connector detect capacitance shifts caused by moisture ingress. The hardware block triggers interrupts and initiates corrosion mitigation mode-disabling VBUS paths and entering low-power state-within ≤200 ms of detection, per Infineon AN235242 guidelines.
Can CYPM1322-97BZXIT operate with a 12 V automotive supply?
Yes. CYPM1322-97BZXIT accepts VSYS input from 2.8 V to 5.5 V, so a 12 V automotive rail requires an external DC-DC buck converter (e.g., Infineon TLE9471-2ES) to generate 3.3 V or 5 V. Its VBUS pins tolerate 4–28 V directly, enabling native connection to automotive battery-sensed lines for PD negotiation without level-shifting.
