3.1 Pin Attributes and Pin Multiplexing
The device makes extensive use of pin multiplexing to accommodate the large number of peripheral
functions in the smallest possible package. To achieve this configuration, pin multiplexing is controlled
using a combination of hardware configuration (at device reset) and register control.
NOTE
TI highly recommends using the CC3200 pin multiplexing utility to obtain the desired pinout.
The board and software designers are responsible for the proper pin multiplexing configuration. Hardware
does not ensure that the proper pin multiplexing options are selected for the peripherals or interface mode
used.
Table 3-1 describes the general pin attributes and presents an overview of pin multiplexing. All pin
multiplexing options are configurable using the pin mux registers.
The following special considerations apply:
• All I/Os support drive strengths of 2, 4, and 6 mA. Drive strength is configurable individually for each
pin.
• All I/Os support 10-µA pullups and pulldowns.
• These pulls are not active and all of the I/Os remain floating while the device is in Hibernate state.
• The VIO and V_BAT supply must be tied together at all times.
• All digital I/Os are nonfail-safe.
