Product details
Overview
CYPM1322-97BZXI from Infineon is a 32-bit Arm® Cortex®-M0+ USB-C Power Delivery MCU with dual PD ports, 256 KB flash, 32 KB SRAM, and integrated NFET gate drivers supporting up to 28 V VBUS. It features full-speed USB 2.0 device controller, hardware crypto (AES-256, SHA2-256, TRNG), CAPSENSE™, dual 8-bit + one 12-bit SAR ADCs, and liquid detection capability. Used in USB-C docks, multi-port chargers, and high-voltage accessories requiring EPR compliance.
For engineers reviewing the CYPM1322-97BZXI datasheet, CYPM1322-97BZXI pinout, CYPM1322-97BZXI application, or CYPM1322-97BZXI equivalent, key selection criteria include dual PD port support, 28 V extended power range (EPR), 97-ball BGA package with SBU analog muxes for DisplayPort/Thunderbolt alternate modes, and integrated corrosion mitigation for moisture-prone connectors.
Technical Context
The CYPM1322-97BZXI implements two independent USB-C PD PHYs with baseband transceivers and dedicated VBUS NFET gate drivers per port, enabling simultaneous sink/source operation with configurable OVP/OCP/SCP/RCP protection. Its programmable analog subsystem includes two opamps, two LP comparators, and CAPSENSE™ sigma-delta blocks with SmartSense auto-tuning.
It integrates a full-speed USB 2.0 device controller with Billboard class support, eight reconfigurable SCBs (I²C/SPI/UART), eight TCPWM blocks, and DMA-assisted data movement between peripherals and memory - all coordinated by a 48 MHz Cortex®-M0+ core with 96 KB ROM-resident PD stack.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPM1321-97BZXI | Same 97-BGA package and dual PD ports, but lacks USB 2.0 device controller and Billboard support | Not suitable for systems requiring USB enumeration of PD status to host OS | Select when USB device functionality is unnecessary and cost optimization is prioritized |
| CYPM1211-48LQXI | Single-port PMG1-S2 in 48-QFN; 128 KB flash, 12 KB SRAM, no crypto engine or CAPSENSE™ | Targeted for cost-sensitive single-port chargers without EPR or security requirements | Select only for simpler, lower-power applications where dual ports and 28 V operation are not required |
Compared with CYPM1321-97BZXI and CYPM1211-48LQXI, CYPM1322-97BZXI uniquely combines dual 28 V PD ports, full-speed USB device + Billboard, hardware crypto, and liquid detection - making it the only option for secure, EPR-capable, moisture-resilient multi-port docks and industrial accessories.

FAQ
What is the maximum VBUS voltage supported by CYPM1322-97BZXI?
CYPM1322-97BZXI supports VBUS up to 28 V, compliant with USB PD 3.2 Extended Power Range (EPR). This rating applies to both input and discharge paths, with integrated OVP and RCP protection active across the full 4–28 V operating range. The internal regulator and gate drivers are qualified for continuous operation at 28 V, validated per Infineon's absolute maximum ratings table.
Does CYPM1322-97BZXI include hardware support for USB PD security features?
Yes. CYPM1322-97BZXI integrates a dedicated hardware crypto engine supporting AES-256 encryption, SHA2-256 hashing, and True Random Number Generation (TRNG). These are used for secure firmware boot validation and signed firmware updates, satisfying USB PD specification Annex K requirements for authenticated firmware loading and runtime integrity checks.
How does the liquid detection feature work on this device?
Liquid detection uses dedicated on-die capacitive sensing circuits that monitor parasitic capacitance changes at the USB-C connector shell and CC pins. When moisture bridges conductive paths, the measured capacitance shifts beyond calibrated thresholds, triggering automatic VBUS shutdown and fail-safe GPIO assertion. Corrosion mitigation mode then holds the port in safe state until dry-out confirmation via periodic re-sampling.
Can CYPM1322-97BZXI operate as both source and sink simultaneously on its two ports?
Yes. Each of the two USB-C PD subsystems operates independently with full DRP (dual-role port) capability. The device can negotiate source mode on Port A while simultaneously negotiating sink mode on Port B - enabling use cases like power passthrough in docks. Role arbitration is handled in firmware using the ROM-resident PD stack, with hardware-enforced isolation between VBUS paths.
