Product details

USB Type-C controller with a Cortex-M0 inside

It integrates the protocol logic for USB Type-C port management, including cable orientation detection and role negotiation, in a single 20-ball WLCSP package measuring 1.63x2.03 mm.

Nine general-purpose I/Os are available for auxiliary signals like VCONN control, dead-battery detection, or status LEDs.

Interface set and system integration

The I²C interface is the typical control channel for reading port status and setting policy; the SPI and UART paths are useful for debug or bridging to legacy peripherals. The 1.71 V minimum supply means it can operate in low-voltage battery systems (e.g., single-cell Li-ion at 3.0 V nominal, down to 1.8 V near end-of-discharge) without a boost converter.

Frequently asked questions

What is the difference between CYPD2103 and CYPD2123?

The CYPD2123 is a different variant in the EZ-PD CCG2 family, but the evidence does not provide its specific specs. The CYPD2103-20FNXIT has 32 KB Flash, 4K x 8 RAM, and 9 I/Os in a 20-WLCSP package. For a pin-compatible alternative with more I/Os, consider the CYPD2122-24LQXIT (24-pin QFN, 14 I/Os, same core and Flash size).
