S130 SoftDevice on chip with 16 KB of RAM

[ppatierno]

Hi,

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. From documentation we see tha S130 needs 10 KB of RAM but and all people on the forum use chip with 32 KB of RAM. Of course the S130 should fit inside the chip with 16 KB (our application needs about 5 KB). Is it true ? Can we use S130 on chip with 16 KB of RAM or we need chip with 32 KB of RAM ? Does a shrinked version of S130 exist ?

Thanks, Paolo.

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?

The only thing you can change with the RAM size is the attribute size with S130. The release notes for it gives clear information of MAX and MIN sizes allowed.
