Is there any BLE chip under development which has lesser IO pins, as I feel most of the IO provided are underutilised.
I may be wrong or there might be technical issue, but I feel that in nRF52832, NFC pins and DCC pin should have been in outer edge of WLCSP package. So to use NFC and DCC pin, multilayer PCB with microvia may have not been required. We are working on PCB, just for accessing NFC pin we have to go for 4-layer PCB for nRF52832 WLCSP package.
