Module Management Controller
The AMC123 includes a Module Management Controller (MMC) based on the Atmel
ATMEGA128L-8MU, which interfaces to the local Intelligent Platform Management bus (IPMB-
L). The MMC monitors and controls the module’s payload per the PICMG AMC.0 specification.
See Chapter 4, “System Monitoring and Alarms,” on page 55 for more information on MMC
functionality, supported commands, AMC123 sensors, and the firmware upgrade process.
The AMC123 is compliant with standard Intelligent Platform Management Interface v1.5
Specification functionality. See “Module Management Controller,” on page 104 , for information
about this specification.
Memory
The AMC123 supports one 200-pin, Small Outline Registered Dual In-line Memory Module
(SO-RDIMM) connector socket that can be populated with a single DDR2-667 Registered
SDRAM (64-bit + ECC). The socket supports up to a 4 GB, 333.5 MHz DDR2-667 memory
module with ECC error detection and correction. The BIOS automatically determines the
SDRAM's size and speed.
An integrated memory controller resides in the Intel EP80579 Integrated Processor, which
supports 64-bit data plus 8-bit ECC and can operate to a maximum clock frequency of
400 MHz.
See “Memory Configuration,” on page 36 , for more information.
USB and SATA Flash Storage Options
The AMC123 includes a 20-pin 2 mm header which supports the installation of one of the
following storage modules for on-board flash storage:
• A standard USB solid-state disk drive (uSSD) with a USB 2.0 interface
• A standard SATA solid-state disk module (SDM) with a SATA II interface
Both devices support up to 16 GB of on-board flash.
The storage modules (uSSD or SDM) can be ordered separately as add-on devices for the
AMC123. A 4 GB module is the standard ordering option. Contact PT’s
“Customer Support and
Services,” on page 16 , for more information. See “uSSD/SDM Storage Interface Connector
(P5),” on page 85 , for storage module installation instructions.
The Intel EP80579 Integrated Processor supports two USB 2.0 host controller ports — one port
dedicated for front-panel (described above), and a second port routed to on-board devices,
such as the uSSD, or to the AMC card edge. The routing of the second port is controlled via a
BIOS setup option. See
“SW4-3 — USB Port 1 Control,” on page 44 , for more information
about this option.
The SATA controller resides in the Intel EP80579 Integrated Processor. See “SATA Interfaces,”
on page 29 , for more information. The topic “Processor,” on page 103 , provides a link to the
data sheet for this device. Connector locations and pinouts for this header, as well as
instructions for installing a storage module, are documented in
“uSSD/SDM Storage Interface
Connector (P5),” on page 85 .
