Hardware Specifications for Programmable Variant
If the module has the programmable secondary processor, add the following table values to the specifications listed on
page 7. For example, if the secondary processor is running at 20 MHz and the primary processor is in receive mode then
the new current value will be I
tota
l = I
r2
+ I
rx
= 14 mA + 9 mA = 23 mA, where I
r2
is the runtime current of the secondary
processor and I
rx
is the receive current of the primary.
