Kontron Security Solution (option)
6.6.
Kontron Security Solution is a combined hardware and software solution that includes an embedded hardware
security module and a software framework to protect applications.
The integrated security module connected to SoC port 7. Therefore, if this option is installed, SoC port 7 is not
available for other interfaces. The main integrate security solution features are:
Copy protection
IP protection
License model enforcement
If required, customers can customize the solution to meet specific needs. For more information, contact Kontron
Support.
LPC
6.7.
The Low Pin Count (LPC) interface signals are connected to the LPC bus bridge located in the CPU or integrated
chipset. 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 sub-system complies with the
Qseven® Specification.
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 that can lead to limitations for the ISA bus.
The LPC Interface signals LPC_AD0 (pin 185), LPC_AD1 (pin 186), LPC_AD2 (pin 187), LPC_AD3 (pin 188), LPC_CLK (pin
189), LPC_FRAME# (pin 190) and LPC_LDRQ# (pin 192) on the Qseven® connector are pin shared with the GPIO. The
CPLD controller incorporates a LPC bridge to support either I2C, to GPIO. An EEPROM bit on the carrier board can
define if the pins are used as GPIO or LPC.
The GPIO or LPC option is configured in the BIOS setup:

(HWM) is accessible via SMB). If any other LPC Super I/O additional BIOS implementations are necessary, contact
Kontron Support.
