2.3.36.
Trusted Platform Module (TPM)
Chip is Infineon SLB9670XQ2.0 (TPM 2.0), connected to FSPI (dedicated SPI interface from PCH for TPM and BIOS
EEPROM).
2.3.37.
Embedded Controller (CPLD)
Altera MAX10 10M02SCU169I7 (FPGA MAX 10 UBGA169 Industrial range) or pin compatible part can be assembled. EC
implements Kontron COMe CPLD Specification 2.8 VHDL block (KCPLD).
KCPLD is connected to TGL eSPI interface to provide several features to the module/carrier:
LPC Bus
I2C
UART (optional)
GPIO
Watchdog
Moreover, the EC is responsible for platform power sequence and reset control for all components.
2.3.38.
SPI BIOS Memory
A 64 MB SPI Flash supporting SFDP (Serial Flash Discovery Parameter) is attached to PCH FSPI interface (dedicated
SPI for TPM and flash memory). Flash Descriptor, BIOS, converged security engine as well as platform data are stored
within the SPI flash.
