Interface and connectivity ICs

What is the maximum number of PDM digital microphones that can be handled with the SAI interface? What will be the best way to interface with around 20 PDM microphones?

Hello, if I understand correctly from the document (https://www.st.com/resource/en/application_note/an5027-interfacing-pdm-digital-microphones-using-stm32-mcus-and-mpus-stmicroelectronics.pdf), the SAI interface can only handle at most 8 PDM digital ...

High Current consumption by SPBTLE-RF BLE Module

Hi, We are using SPBTLE-RF BLE module in our design. In Production, We are observing the following issues.Observation-1:After the PCB is assembled.When we do Power Check. On few PCBAs We are observing current value of 70mA to 80mA. If we isolate the ...

Why BlueNRG LP not working as HCI-UART, DTM example not works! Not scanning from Bluez 5.53

How I use the BlueBRG as HCI-UART, on Bluez 5.55 stack as BT LE LR Dongle, command on btmgmt "find -l" thoes return nothing... ?

For RH FACT logic, what happens when I violate the slew requirement?

We are using the RHFACT04 gate. In a fault-mode, where the path between an external driver and this receiver is broken, the input will be pulled down by a 10k resistor. At maximum input capacitance this violates the DSCC of 0 - 8ns/V slew on the inpu...
