Direction
Pin Type
J60 STANDBY_
ACK_N
SOC_PWR_REQ Standby Acknowledge. Indicates module is in
standby (SC7 state). Signal should only be
observed and not affected by the carrier board. A
buffer on the signal is recommended if it will be
connected in the platform.
Automation header Output CMOS – 1.8V
L11 STANDBY_
REQ_N
SOC_GPIO01 Standby Request. Requests module enter standby
(SC7 state). 10kΩ pull-
up to 1.8V is present on the
module.
Not used Input CMOS – 1.8V
System Reset: Connected to NRST_IO of PMIC.
Bidirectional reset driven from PMIC to carrier
board for devices requiring full system reset. Can
also be driven from carrier board to module to
initiate full system reset (including PMIC) (i.e.
From RESET button). 1kΩ pull-up to 1.8V is
present on the module.
functions. Also routed
to reset button, JTAG
header, and automation
header.
A61 SYSTEM_OC_N BATT_OC Battery Over-current (and Thermal) warning Automation Header Input CMOS – 1.8V
F61 VCOMP_
ALERT_N
VCOMP_ALERT Supports either GPIO operation or SoC Thermal
Over-current alert #1.
Unused Input CMOS – 1.8V
L55 VDDIN_PWR_
BAD_N
− VDD_IN Power Bad. Carrier board indication to
the module that the VDD_IN power is not valid.
Carrier board should de-assert this (drive high)
only when SYS_VIN_HV/MV have reached the
required voltage levels and are stable. This
prevents SoC from powering up until the main
input supply voltages are stable. 10kΩ pull-up to
5V on the module.
Driven by VIN loss
detection, USB PD
power and discharge
circuits. Used in power
button supervisor
circuit.
Input
Open-drain – 5.0V
OUT_N
L52 OVERTEMP_N SOC_GPIO55 Force Power Off Request Routed to power button
supervisor circuit.
Input CMOS – 1.8V
L56 TEMP_ALERT_N − ALERT*/THERM2 from Temp Sensor on module Unused Output Open Drain, 1.8V
A3 PRSNT0 − Present #[1:0]. Tied together on module. Used to
detect when module is connected to the carrier
board. Can be used to keep carrier board from
powering the module until the module is installed
in the carrier board.
Tied to GND na na
L63 PRSNT1 −
Tied to one side of
power button.
K40 MID0 − Module ID #0 Tied to GND na Na
H40 MID1 − Module ID #1 Unconnected na na
