ID 1036-1669, Rev. 1.0 Page 2 - 7

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

4VCC5V Power +5V O

5 PWM_OUT Fan speed control via pulse with

modulation signal

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.
