16, 17, 25, 26, 28, 29, 30, and 32

Output source current for pad numbers 3, 4, 5, 10, 12, 14, 16,

17, 26, 28, 29, 30, and 33

Output source current for pad numbers 7, 8, 24, 31, and 33

Output sink current for pad numbers 7, 8, 24, 31, and 33

Total output current (for GPIO pads)

Hardware Specs 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

recieve 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 recieve current of the primary.

Specifications of the programmable secondary processor

Optional Secondary Processor Specification

Runtime current for 32k running at 20MHz

Runtime current for 32k running at 1MHz
