Product details

The CYPD3125-40LQXIT: The wide supply tolerance also simplifies power routing in systems where the USB bus voltage is the primary rail.

40-QFN with exposed pad — rework considerations

The exposed pad helps dissipate heat from the Cortex-M0 core during active USB PD negotiation, but it also means the part is not hand-solderable without a hot-air station or reflow oven. The pad is large enough that a standard QFN rework profile works well — just pre-tin the pad and use a stencil for the perimeter pins to avoid bridging.

Frequently asked questions

What are the alternatives to CYPD3125-40LQXIT if it is out of stock?

A functional alternative within the EZ-PD family is the CYPD2122-24LQXIT (CCG2 series), which also uses an ARM Cortex-M0 core but has 32 KB Flash, 4K x 8 RAM, and 14 I/O in a smaller 24-QFN package. It is not a direct pin-compatible replacement — the pin count and footprint differ — but it can serve a similar USB-C role with reduced memory and I/O.
