Functional Description
ATCA-8330 Installation and Use (6806800S82B) 123
5.15.1 IPMC Debug Console
The IPMC Debug Console IF connection is normally routed to a 3-pin onboard header (RS232)
The IPMC Debug monitor terminal output can also be routed to the Faceplate. The IPMC Debug
Console is also available when the ATCA-8330 Payload is powered off.
5.16 USB 2.0 Interfaces
The PCH Intel DH8900CC provides internal USB1.1/ USB 2.0 host controllers with up to six
USB2.0 ports (480Mb/s). Two ports are routed to the faceplate and are available at a dual
stacker connector. The ports are USB 2.0 compliant.
5.17 LPC Interface
The PCH provides a 4 bit wide low pin count (LPC) interface running at 33MHz, is connected to
following onboard I/O devices:
 Glue Logic FPGA register map
 IPMC Controller
 TPM Unit
5.18 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 attacks.
