Product details

USB Type-C controller with wide-voltage PD negotiation

The device integrates I²C, SPI, and UART interfaces for host communication — useful for reporting port status to a system MCU or for firmware updates over a debug UART. With 12 general-purpose I/O, it can drive external FETs, status LEDs, or enable signals for companion power stages.

Sourcing and procurement posture

For dual-source resilience, the CYPD2122-24LQXIT (EZ-PD CCG2 series) is a pin-compatible sibling with a smaller 32KB Flash and 85°C temperature limit, suitable for lower-power or cost-sensitive builds.

Frequently asked questions

Does CYPD3174-24LQXQ support USB PD 3.0?

Yes, as an EZ-PD CCG3PA series controller with an ARM Cortex-M0 core and 64kB Flash, it supports USB Power Delivery 3.0 protocol negotiation, including PPS (Programmable Power Supply) profiles. The wide 3V to 24.5V supply range allows direct VBUS connection for PD negotiation up to 20V.

What is the difference between CYPD3174-24LQXQ and CYPD2122-24LQXIT?

The CYPD2122-24LQXIT (EZ-PD CCG2 series) is a lower-cost sibling with 32KB Flash (vs 64KB), a narrower temperature range (-40°C to 85°C vs -40°C to 105°C), and a lower supply voltage (1.71V vs 3V–24.5V). The CYPD3174-24LQXQ offers wider voltage operation and higher temperature tolerance, making it the choice for industrial or high-voltage PD applications.

Does CYPD3174-24LQXQ require an external EEPROM?

No, the 64kB Flash program memory stores the firmware and configuration data internally. No external EEPROM is required for normal operation, though the I²C interface can be used to attach one for additional data storage if needed.
