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
total
= 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.
Output source current 2 mA
Output sink current 2 mA
Total output current (for GPIO pins) 48 mA
