This is essentially a repeat of :
Instead of the nRF52840, I am now inquiring about the nrf9160 SoC.
Repost of the pertinent question:
My problem is that I need to acquire 2-5ms of data from a sensor with a 3 bit parallel interface clocked at 16.384Mhz (around ~32kilobytes of data with 3bits of data stored per byte of RAM).
Is this possible with the nrf9160?
