Interface and connectivity ICs

What is the pin capacitance of CC1/CC2 and DB pins on the STUSB1602?

The PD specification calls for 200-600pf on CC1 and CC2 (each). With 330pf on both CC1 and CC2 to GND, I see intermittent errors (missed PD messages, not received). It is infrequent but it happens. Removing these capacitors clears it up. What is the ...

STEVAL-ISC004V1 VBUS LED blinks when I am trying to power up my device.

Hello,I am using a STEVAL-ISC004V1 to power up a device (PD sink) that needs 24W (15V 1.6A) power supply to power up and charge the battery. When I connect the STEVAL-ISC004V1 to the device the VBUS LED does not show a solid green and flashes. My dev...

BLE microphone design based on SPBTLE-1S

I started working on a low energy microphone based on SPBTLE-1S. I bought a STEVAL-BLUEMIC-1 module and designed a custom PCB  with only a digital MEMS microphone MP34DT05-A and removed the  LSM6DSL. Other buttons and LEDs are the same as the evaluat...
