nRF51822 NVMC power spec?

I can't seem to find the required current of NVMC doing erase and write. The product spec has only timings but not more. Could someone from Nordic provide some figures? Experimental measurements are welcome too!

I need this information to determin how to implement Flash updates, e.g., is OTA DFU feasible on my battery powered device, or should I forget about OTA and only do wired upgrade? And if it's possible, what are the considerations about DFU image size and battery type?

Thanks!

  • Thanks Rallare. That's an encouraging number. I looked up other vendors' comparable chips (Cortex M0, M0+, M3), and their flash write current are in the range of 5~7 mA. It seems nRF51 integrated a better type of low-power Flash memory.

    Well done Nordic. Hope you can put more data into the spec. Like this one, and the one of GPIOTE. We also like to see more low-power goodies -- how about DMA-enabled peripherals?
