7.11 Feature Connector (Feature) (J1)

Notes: 1. Pull-up to +3V3Dual (+3V3 or SB3V3). 2. Pull-up to on-board Battery. 3. Pull-up to +3V3. 4. Not

Available. 5. Not available on mITX, Shared with onboard FAN2 on Flex.

Signal Description

CASE_OPEN#

CASE OPEN, used to detect if the system case

has been opened. This signal’s status is

readable, so it may be used like a GPI when the Intruder switch is not required.

SMBC SMBus Clock signal

SMBD SMBus Data signal

S3# S3 sleep mode, active low output, optionally used to deactivate external system.

S5# S5 sleep mode, active low output, optionally used to deactivate external system.

PWR_OK

PoWeR OK, signal is high if no power failures are detected. (This is not the same as the

P_OK signal generated by ATX PSU).

EXT_BAT

(EXTernal BATtery) option for connecting + terminal of an external primary cell battery (2.5

- 4.0 V) (–

terminal connected to GND). The external battery is protected against charging

and can be used with/without the on-board battery installed.

FAN3OUT FAN 3 speed control OUTput, 3.3V PWM signal can be used as Fan control voltage.

FAN3IN FAN3 Input. 0V to +3V3 amplitude Fan 3 tachometer input.

FAN4OUT FAN 4 speed control OUTput, 3.3V PWM signal can be used as Fan control voltage.

FAN4IN FAN4 Input. 0V to +3V3 amplitude Fan 3 tachometer input.

SB3V3 Max. load is 0.75A (1.5A < 1 sec.)

SB5V StandBy +5V supply.
