https://devzone.nordicsemi.com/f/nordic-q-a/9412/s130-softdevice-on-chip-with-16-kb-of-ramHi, until today we develop our application on Nordic DK with nRF1422 with 32 KB of RAM. We are using S130 and SDK 8.1.0. Today we saw that our target module, the MBH7BLZ07 module from Fujitsu (with nRF1822), has only 16 KB of RAM.

The release notes for it gives clear information of MAX and MIN sizes allowed.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/34724?ContentTypeID=1Thu, 24 Sep 2015 14:38:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4602f222-d552-406b-94aa-75fb0f83fec9ppatierno<p>I was thinking if S130 has some features I don&#39;t need so that I can customize it only with features useful for me. How much is the bootloader weight inside the RAM ? However I&#39;m a bit confused. When I use the nRFgo Studio I flash the S130 hex file and then use the Keil IDE to flash my application ... no bootloader.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/34723?ContentTypeID=1Thu, 24 Sep 2015 10:32:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6e13611f-199b-44ff-a101-e43bffd28515Susheel Nuguru<p>you can use it Rev 3 Chips with 16KB RAM but application and bootloader will be left with only with 6KB of RAM. What do you mean by shrinked version of S130?</p><div style="clear:both;"></div>
