5.3 External communication interfaces
FC7100 module uses several means to interface with the system it is integrated in.
5.3.1
Digital IO Pins
The FC7100 I/Os belong to 3 different
The transmission line must be adapted to 50 ohm, at all available frequencies
VDDO is the generic power supply name of the power domain. It can represent 3V3_MAIN,
VDD_ETH, VDD_SD1 or VDD_SD2.
5.3.1.1
3,3V power domain
(Condition: VDD = 3.3v)
Parameter
Input Low Voltage VIL
Input High Voltage VIH
Low Level Output Voltage VOL
High Level Output Voltage VOH
Max Output Current
Please note that it is forbidden to apply a VIH on an unpowered GPIO, so when its VDDO isn’
supplied.
5.3.1.2
2,5V power domain
(Condition: VDD = 2.5v)
Parameter
Input Low Voltage VIL
Input High Voltage VIH
Low Level Output Voltage VOL
High Level Output Voltage VOH
Max Output Current
Please note that it is forbidden to apply a VIH on an unpowered GPIO, so when its VDDO isn’t
supplied.
5.3.1.3
1,8V power domain
(Condition: VDD = 1.8v)
Parameter
Input Low Voltage VIL
Input High Voltage VIH
Low Level Output Voltage VOL
High Level Output Voltage VOH
Max Output Current
