9/ Features and Interfaces

9.1. ACPI Power States

ACPI enables the system to power down and save power when not required (suspend) and wake up when required
(resume). The ACPI controls the power states S0-S5, where S0 has the highest priority and S5 the lowest priority. The
COMe-cDV7 comes with ACPI 4.0 and supports the power states S0, S4, S5 only.
Not all ACPI defined states are available.
SoC systems that support the low-power idle state do not use S1-S3.

Table 16: Supported Power States Function

S0
S4
S5
The following events resume the system from S4 (Suspend-to-disk/Hibernate):
 Power Button
 WakeOnLan
The following events resume the system from S5 (Soft-off state):
 Power Button
 WakeOnLan
OS must support wake up by USB devices and the carrier board must power the USB Port
with standby voltage. Depending on the Ethernet used (MAC or Phy), WakeOnLan must be
enabled in the BIOS Setup and driver options.

9.2. APPROTECT Security Solution

Kontron's Security Solution is a security chip for Kontron's security stack (APPROTECT). The security solution combines
a software framework with an integrated security chip connected to the COMe-cDV7's USB 2.0 port 3 and an additional
TPM 2.0 (Trusted Platform Module) chip to provide comprehensive protection for the application software. Kontron
APPROTECT encrypts an application's source code in a way that makes reverse engineering impossible (IP Protection/
Reverse Engineering Protection).
Kontron's APPROTECT licensing additionally adds:
 License model enforcement
 Enablement of new business models by offering SDKs and software integration
 Based on time base, by counting executions or by enabling/disabling features
 Software management framework
After purchasing Kontron APPROTECT, a new firmware code for the security chip will be provided that can be installed
by Kontron or by the user. If required, users can customize the solution to meet specific needs. For more information,
contact Kontron Support.
