GPIOs 

GPIO pins from different sources are available on the MBLS1012AL. 
 
 

Native GPIOs 

The TQMLS1012AL provides six GPIO signals on the configuration selected for the MBLS1012AL. All GPIO signals configured as 

input are interrupt capable.

Attention: GPIO1_29 

 

GPIO1_29 can only be configured as an output.  
This pin must not be pulled low during the reset cycle!  

See also (1), table 1 (GPIO1_29) note 5, and (2), chapter 20.1. 

 
 

Port Expander GPIO: 

Two GPIO port expanders are used (see also section 4.5.3), of which three pins are available on the header. 
GPIO pins which are implemented via a port expander are usually not suitable for time-critical I/O operations due to their indirect 

connection to the CPU. In addition, it should be noted that these pins are only available with a delay at boot time, since the I

2

driver must first be loaded for the configuration. 
The nominal signal level of the GPIO signals GPIO_3V3_[3:1] is 3.3 V. The GPIO signals GPIO_3V3_[3:1] have a nominal signal level 

of 3.3 V. However, the pins are 5 Volt tolerant and can be operated with an external signal level up to a maximum of 5.5 V. The 

GPIO signals can be used with a maximum of 5.5 V. 
At the pins GPIO_3V3_[3:1], a current of max. 25 mA can be switched). For more detailed information, refer to the data sheet of 

the port expander.
