Product details
Overview
CYPD2125-24LQXIT from Cypress Semiconductor is a USB Type-C port controller IC implementing full USB Power Delivery (PD) 2.0 protocol stack, integrated Arm® Cortex®-M0 CPU (48 MHz), 32-KB flash, 4-KB SRAM, and on-die Type-C transceiver with RP/RD/RA termination resistors. It supports one USB Type-C port in UFP, DFP, or EMCA cable roles and operates across –40 °C to +105 °C.
For engineers reviewing the CYPD2125-24LQXIT datasheet, CYPD2125-24LQXIT pinout, CYPD2125-24LQXIT application, or CYPD2125-24LQXIT equivalent, key selection criteria include CC line BMC decoding capability, dual VCONN rail support, ±8-kV IEC61000-4-2 ESD rating on CC/VCONN pins, programmable RP current sources, and 24-pin QFN industrial-temperature packaging.
Technical Context
The device integrates a dedicated USB-PD subsystem with baseband PHY performing 4b/5b encoding/decoding and BMC modulation/demodulation, plus an 8-bit SAR ADC with DAC and comparator for analog monitoring of VCONN, CC voltage, and temperature. Its two reconfigurable serial communication blocks (SCB) support I2C (up to 1 Mbps), SPI, or UART-each with 8-deep FIFOs and flexible multiplexing.
Power management includes three operating modes (Active, Sleep, Deep Sleep), with Deep Sleep consuming only 2.5 µA and supporting wakeup via CC detect or VCONN events. The internal IMO eliminates external clock requirements, while GPIOs support 1.71–5.5-V signaling with selectable drive strength, slew rate, and hold mode for state retention during Deep Sleep.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0 @ 48 MHz - enables deterministic USB-PD message timing and firmware-upgradable protocol stack execution. |
| Memory | 32-KB flash / 4-KB SRAM - sufficient for full PD 2.0 stack plus custom vendor-defined messages and policy engine logic. |
| Type-C Transceiver | Integrated baseband PHY with RP/RD/RA termination - eliminates discrete resistors and reduces BOM count for single-port implementations. |
| ESD Rating | ±8-kV contact / ±15-kV air-gap on CC/VCONN - meets IEC61000-4-2 Level 4C for robust field deployment in consumer and industrial accessories. |
| Operating Temp | –40 °C to +105 °C - qualified for extended industrial environments including powered docks and automotive dongles. |
| VCONN Support | Dual independent VCONN rails with integrated isolation - enables simultaneous powering of active cable components and embedded accessories without cross-rail coupling. |

| CC2 | Configuration Channel 2 | Redundant CC path for flip-over detection and alternate-role negotiation; required for full Type-C cable compliance. |
| RD1 | Dedicated Rd resistor pin | Hardwired Rd termination for CC1; must be open for cable applications, tied to CC1 for UFP/DFP dead-battery fallback. |
| VCONN1 / VCONN2 | Dual VCONN power outputs | Independent 5-V regulated outputs with isolation; powers active cable electronics or EMCA accessories without shared ground noise. |
| I2C_0_SCL / I2C_0_SDA | Primary I2C interface | Configurable as master/slave I2C bus (up to 1 Mbps); used for host MCU communication and firmware configuration via EZ-PD Utility. |
| GPIO13 / GPIO15 / GPIO18 / GPIO22 | Multi-function GPIOs | Support SPI, UART, or general-purpose I/O; enable status LED control, button input, or auxiliary power sequencing signals. |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable SCBs | Two serial blocks independently configurable as I2C/SPI/UART - simplifies system integration with host MCUs or PMICs without adding protocol bridges. |

| Deep Sleep Wakeup Sources | CC line activity, VCONN presence, or GPIO edge - allows zero-power standby until physical connection event, critical for battery-powered accessories. |
| On-chip Analog Monitoring | 8-bit ADC with 4-input analog mux, DAC, and comparator - replaces external sensing circuitry for VCONN regulation, overvoltage protection, and thermal derating. |
| SWD Debug Interface | 2-wire Serial Wire Debug with 4 breakpoint/2 watchpoint comparators - enables in-system firmware update and real-time protocol debugging without JTAG header footprint. |

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 |
|---|---|---|---|
| CYPD3125-40LQXIT | Higher-performance CCG3 with USB PD 3.0 support, 64-KB flash, hardware PD packet parser, and enhanced security features. | Required for PPS, EPR, and secure firmware updates in premium notebooks and certified chargers. | Select when PD 3.0 compliance, cryptographic authentication, or higher memory headroom is mandatory. |
| STUSB4500QTR | Dedicated PD controller (no MCU), fixed-function silicon with 32-KB ROM, no flash reprogrammability, and no integrated ADC. | Suitable for cost-sensitive, single-role applications like fixed-sink adapters where firmware customization is unnecessary. | Select when minimal BOM cost and guaranteed firmware immutability outweigh flexibility and analog monitoring needs. |
Compared with CYPD3125-40LQXIT, CYPD2125-24LQXIT offers lower gate count and power consumption but lacks PD 3.0 features; versus STUSB4500QTR, it provides full firmware upgradability and integrated analog sensing at higher design complexity and cost.

FAQ
Is CYPD2125-24LQXIT compatible with USB PD 3.0?
No. CYPD2125-24LQXIT implements USB PD specification revision 2.0 only. It does not support Programmable Power Supply (PPS), Extended Power Range (EPR), or cryptographic authentication features introduced in PD 3.0. For PD 3.0 compliance, CCG3 (e.g., CYPD3125) or CCG6 devices are required.
Does this device require an external crystal oscillator?
No. CYPD2125-24LQXIT integrates an Internal Main Oscillator (IMO) capable of 48 MHz operation, eliminating the need for external timing components. The IMO is factory-trimmed to ±2% accuracy, sufficient for USB-PD BMC timing requirements without crystal loading or board space overhead.
Can CYPD2125-24LQXIT support dual-role port (DRP) functionality?
Yes, but with firmware-level implementation. The device supports both UFP and DFP roles via software configuration of termination resistors (RD/RA/RP) and BMC message handling. DRP behavior-including role swap initiation and response-is implemented in the user's firmware using Cypress-provided SDK libraries.
What debug interfaces are supported for firmware development?
CYPD2125-24LQXIT supports Serial Wire Debug (SWD) via dedicated SWDIO and SWCLK pins. It includes four hardware breakpoints and two watchpoints, enabling real-time code stepping, register inspection, and memory access debugging. The EZ-PD Configuration Utility and ModusToolbox™ IDE provide full toolchain support.
