FAN_PWNOUT B101 O OD CMOS 3.3V / 12V Fan speed control. Uses the Pulse Width Modulation (PWM) technique to control the fan's RPM.
FAN_TACHIN B102 I OD CMOS 3.3V / 12V PU 10K TO 3V3 Fan tachometer input for a fan with a two pulse output.
TPM_PP A96 I CMOS 3.3V / 3.3V PU 0 TO 3V3_DU NC PU 4.7K TO 3V3_SB
Trusted Platform Module (TPM) Physical Presence pin. Active high.
TPM chip has an internal pull down. This signal is used to indicate
Physical Presence to the TPM.
Signal Pin# Pin Type Pwr Rail /Tolerance HM960-QM87/HM86 Carrier Board Description
PWRBTN# B12 I CMOS 3.3V Suspend/3.3V PU 10K TO 3V3_DU_EC PU 4.7K TO 3V3_SB
A falling edge creates a power button event. Power button events can
be used to bring a system out of S5 soft off and other suspend states,
as well as powering the system down.
SYS_RESET# B49 I CMOS 3.3V Suspend/3.3V PU 10K TO 3V3_DU NC PU 4.7K TO 3V3_SB
Reset button input. Active low request for Module to reset and reboot.
May be falling edge sensitive. For situations when SYS_RESET# is
not able to reestablish control of the system, PWR_OK or a power
cycle may be used.
CB_RESET# B50 O CMOS 3.3V Suspend/3.3V
Reset output from Module to Carrier Board. Active low. Issued by
Module chipset and may result from a low SYS_RESET# input, a low
PWR_OK input, a VCC_12V power input that falls below the minimum
specification, a watchdog timeout, or may be initiated by the Module
software.
PWR_OK B24 I CMOS 3.3V / 3.3V PU 10K TO 3V3
Power OK from main power supply. A high value indicates that the
power is good. This signal can be used to hold off Module startup to
allow Carrier based FPGAs or other configurable devices time to be
programmed.
