I/O s on DRA7xx

Hi Champs,

Would you be able to help here please on the no. of digital inputs/outputs & analog inputs this chip is capable of supporting?

 

We have Up to 247 General-Purpose I/O (GPIO) Pins. However not sure any Analog inputs. Can you please clarify how it’s implemented for inputs form other ECUs/Sensors? Any recommended ADCs? Can you please let me know?

 

Thanks!

 

Best Regards

Feroz

    Hi Feroz,

    DRA7xx does not have analog inputs as ADC is not available on that SoC. If you have to measure analog signals you should use external ADC with SPI, I2C or another type of interface. I can't recommend specific ADC as I don't know what is the target of your application. TI offers many types of ADCs. You can find them here:
    www.ti.com/.../analog-to-digital-converter-products.page

    Use the filters to specify what you wish (e.g., number of channels, resolution, sample rate, interface, etc...).

    Please take also into account that the GPIO signals are muxed along with other signals on the DRA7xx pins, so all GPIOs may not be available at a time.
