The nature of this security chip ensures that the information like keys, password, and digital
certificates stored within is made more secure from external software attacks and physical
theft. With the handful of keys it stores, all cryptographic functions are performed on the chip.
TPM provides the ability for a computing system to run applications more secured, allows
secured remote access, performs electronic transactions and communication more safely.
The ATCA-7475 provides an onboard Infineon SLB9635TT1.2 FW3.16 TPM Controller
connected to the LPC bus of the PCH. This advanced Infineon controller guarantees that ATCA-
7475 is fully compliant to TPM 1.2 specification.
5.19 Real Time Clock
An external 32.768 kHz clock sources the internal real time clock inside Intel DH8900CC PCH
with a frequency tolerance of 20 PPM. The RTC is fully DS1287, MC14618, PC87911, and Y2K
compliant and provides 256 bytes of backed up CMOS RAM (of which 14 bytes contain the RTC
time and date info and RTC configuration). During power-down, the RTC consumes 0.9uA/hr.
Default power-down backup solution is an ex3V lithium battery with a capacity of
200mAh, which provides 3 years of backup.
Optional power-down backup method uses a Super CAP with a 1 Farad capacity. This
provides 300 hours of RTC/SRAM backup.
5.20 ATCA-7470 Accelerator Module Slot
The ATCA-7475 provides the possibility to assemble the ATCA-7470-Accelerator module. The
ATCA-7470-Accelerator module is equipped with two additional Intel DH8920CC SKU4 PCH
devices. The SKU4 variant of the Intel DH8920CC provides a x16 PCIe Gen2 target interfaces
and thus high bandwidth datapath to both CPUs of the ATCA-7475. Each Intel DH8920CC
connects with a x16 PCIe Gen2 interface to each Xeon E5-2600 V2 CPU on the ATCA-7475. The
purpose of the Acceleration module is to provide two additional Next Generation
Communications Platform Controller hubs with their respective QuickAssist technology
coprocessors. The ATCA-7470-Accelerator module gives additional Packet processing
resources to the ATCA-7475 carrier board.
