The SMART FAN ™ technology controls the duty cycle of the fan output (FAN_PWMOUT) with temperature setting
points. This enables flexible fan control for cooling solutions and noise sensitive solutions. For system protection, users
can set threshold values for alarm signals.
9.7. LPC
The Low Pin Count (LPC) Interface signals are connected to the LPC bus bridge located in the SoC. The LPC low speed
interface can be used for peripheral circuits such as an external Super I/O Controller that typically combines legacy-
device support into a single IC. The implementation of this subsystem complies with the COM Express® specification.
The COM Express® Design Guide maintained by PICMG provides implementation information or refer to the official
PICMG documentation for more information.
The LPC bus does not support DMA (Direct Memory Access). When more than one device is used on LPC, a zero delay
clock buffer is required. This leads to limitations for ISA bus and SIO (standard I/Os such as floppy or LPT interfaces)
implementation. The COMe-cDV7 LPC clock buffer allows for the connection of three LPC devices
All Kontron COM Express® Computer-on-Modules include BIOS support for the following external carrier board LPC
Super I/O controller features for the HWM chip Nuvoton NCT7802Y.

Features marked as not supported do not exclude OS support, except for HWM. The HWM is accessible via the System
Management (SM) Bus, see Chapter 10.6: System Management (SMBus); and controlled within the BIOS setup menu

9.8. Quick Assist Technology (Intel® QAT)
The Intel® Quick Assist Technology® (QAT) improves the performance of systems used in applications such as the cloud,
networking, big data and storage by speeding up cryptographic workloads. Intel® QAT improves performance by
offloading data to hardware capable of optimizing cryptology functions such as integrated built-in cryptographic
accelerators and security applications.
This enables users the flexibility to choose different cryptographic accelerators and to scale using multiple
cryptographic accelerators if required.
To use the Intel® Quick Assist Technology® refer to the operating systems compatibility information.
9.9. RTC
The Real Time Clock (RTC) keeps track of the current time accurately. The RTC's low power consumption means that
the RTC can be powered from an alternate source of power enabling the RTC to continue to keep time while the primary
source of power is switched off or unavailable. A typical RTC voltage is 3 V with a current of less than 10 μA. If the
module is powered by the mains supply, the module's RTC voltage is generated by on-module regulators to reduce RTC
current draw. The RTC's battery voltage range is 2 V to 3.3 V.
The RTC battery input may be left open on the carrier board if an application does not
require the RTC to keep time when the main power source is off or unavailable.
