Maximum number of connected slave devices

Last Updated:02/13/2017

Question:

What is the maximum number of slave devices which can be connected to the RL78/G1D as a master?

Answer:

Up to 8 slave devices can be connected simultaneously when using the 20 KB RAM model.
The number of connected units depends on the RAM capacity, and it may be necessary to reduce the number of slave units depending on the application RAM usage.
Based on our protocol stack, the fixed overhead for Bluetooth low energy technology implementation about is 8KB. Each additional slave device requires about 1.5 KB memory in the master.
