2.1.4 Peripheral Control Interface
A fan for system cooling and a power supply with power management can be connected to the
CP-RIO3-04S via the peripheral control connector J13.
The following figure illustrates the peripheral control connector J13.
Figure 2-5: Peripheral Control Connector J13
The following table indicates the pinout of the peripheral control connector J13.

PIN SIGNAL DESCRIPTION I/O
1 GND Signal ground --
2 PWR_5VSTDBY +5V standby power (optional) I
3 FAN_SENSE Fan speed monitor I
4 VCC5V Power +5V O
5 PWM_OUT Fan speed control via pulse with
modulation signal O
6 VCC3V3 Power +3.3V O
7 PWR_SLPS3# Power supply sleep mode O
8 GND Signal ground --
9 PWR_BTN# Wake-up / sleep input I
10 GND Signal ground --
Note ...
Pin 5 is an open drain output and has no pull-up resistor on the CP-RIO3-04S.
Therefore, an external pull-up resistor is required for fan control operations.
