In datasheet it had been mentioned that in SPIM0,SPIM1,SPIM2 the SPI clock frequency should not exceed more that 8 Mhz. And SPIM3 nothing is mentioned. Can we understand that SPIM3 allows sck more that 8MHz. ?

Hi,
SPIM3 is unfortunately not functional on the Engineering A revision of nRF52840 (The chip that is on the nRF52840 Preview DK). This will be added to the errata list as soon a possible. When the production ready chip is released later this year, the SPIM3 will be a high speed SPIM (supporting up to 32 MHz).

ok. Thank you very much for the info. May I know what would be the approximate release date of the latest chip.?
The production variant is expected in Q4 2017.
Hi, Does the same issue exists with nrf52832 IC? Can we configure SPI clock for more than 8 MHz?
The nRF52832 don't have a SPIM3, it only have SPIM0 -> SPIM2, where the max is 8 MHz. What are you interfacing with nRF5x ? Note that the nRF52840 also have Quad SPI that you can use to interface with a external flash memory. The QSPI supports 32 MHz.
Can I use QSPI to interface with SPI slave device, instead of external flash. I am trying to interface with an SPI slave device which required ~20MHz clock to achieve better performance.
