Description
Port 1
I/O Signals
Port 1 pins, P1.0 to P1.7 (DIO0 to DIO7). All FT51A
digital functions can be mixed to these pins; however
ADC features are not available for these pins. These
pins are 5 volt tolerant.
Port 3
I/O Signals
Port 3 pins, P3.0 to P3.7 (DIO8 to DIO15). All FT51A
digital functions can be mixed to these pins; however
ADC features are not available for these pins. These
pins are 5 volt tolerant.
Port 2
I/O Signals
Port 2 pins, P2.0 to P2.7 (AIO8 to AIO15). ADC features
are available for these pins however these pins are not
suitable for high frequency data transfers such as SPI.
These pins are not 5 volt tolerant.
Port 0
I/O Signals
Port 0 pins, P2.0 to P0.7 (AIO8 to AIO15). ADC features
are available for these pins however these pins are not
suitable for high frequency data transfers such as SPI.
These pins are not 5 volt tolerant.
