2.1 Host Interconnect
The Intel® RealSense™ ID Solution F450 module requires external power and a serial
data link for initialization and control of the Face Authentication system. Data signals
and external power are both routed through the same host connector interface.
2.1.1 Data Interface
The Intel® RealSense™ ID Solution F450 supports both UART and USB2 interfaces for
the data link. The boot up interface is configured through a FW and module strap
option.

USB2 480Mbs USB2_DP (Pin 46), USB2_DN (Pin 48)
2.1.2 Power Interface
The Intel® RealSense™ ID Solution F450 module has a peak power of up to 3W. The
host system must ensure the power supply can satisfy this peak power based on the
chosen
Intel® RealSense™ ID Solution F450 voltage source (VDD). If the host
module supports power gate control it is the responsibility of the host module to
ensure no conflicts between power sequencing and data link initialization occurs
during power-up and power-down cycles.

GND - -
NOTES:
(1) The power range is primarily dependent on illumination power set by the device.
(2) The typical max current for a USB2 port is 450mA, USB3 port is 900mA.
The Intel® RealSense™ ID Solution F450 supports three device states, off, standby,
and operation. In the off state the Intel® RealSense™ ID Solution F450 is shutdown
and the power supply from the host is disabled. In the standby, the Intel®
RealSense™ ID Solution F450 power supply is enabled, the SOC is in an execution
loop for manageability access or FW update, but the optical components are powered
down. In the operation state, the power supply is enabled, SOC is running FA
enrollment or authentication usage with the optical components activated.
