ATCA-7480 Installation and Use (6806800T17A) 94
4.16 USB 3.0 Interfaces
The PCH Intel C612 (Wellsburg) provides internal USB 3.0/ USB 2.0 host controllers with up to
six USB 3.0 ports (480Mb/s) and eight USB 2.0 ports. Two USB 2.0 ports are routed to the
faceplate and one USB 2.0 port is routed to the RTM. The ports available at the faceplate are
routed to a dual stacked connector. The ports are USB 3.0 compliant.
4.17 LPC Interface
The PCH provides a 4-bit-wide low pin count (LPC) interface running at 33MHz, which is
connected to following on-board I/O devices:
 Glue Logic FPGA register map
 IPMC Controller
 TPM Extension Module Header
4.18 Trusted Platform Module
The Trusted Platform Module (TPM) is a specific protected and encapsulated microcontroller
security chip used to defend the internal data structures against real intelligent attacks.
The nature of this security chip ensures that the information like keys, password, and digital
certificates stored within are 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-7480 provides an on-board Infineon SLB9635TT1.2 FW3.16 TPM Controller
connected to the LPC bus of PCH. This advanced Infineon controller guarantees that ATCA-
7480 is fully compliant to TPM 1.2 specification. ATCA-7480 is ready to migrate to TPM 2.0.
