NAMC-MMC-RefDesign

Module Management Controller (MMC) Reference and Design Package

Any Advanced Mezzanine Card (AMC) that is compliant with the PICMG AMC.0 specification has to implement a Module Management Controller (MMC) so that is can be manged by shelf and carrier managers via the Intelligent Platform Management Interface (IPMI).

The MMC Design Package by N.A.T. enables customers to implement a fully AMC and IPMI compliant MMC on their custom AMCs, benefiting from N.A.T.'s MMC expertise and experience origin from field proven design such as the well recognized MicroTCA Controller Hub (MCH) NAT-MCH and own AMCs.

The MMC Design Package consists out of a license for the MMC firmware and the reference schematics for the MMC hardware.

Hardware circuitry and supported sensors

The MMC hardware is based on the ATXMega family of MCUs from Atmel. There is a wide variety of chips available which suits nearly any demand of user I/O and memory. For the IPMI controller design only a few requirements are mandatory to support:

2 x IC2 interface for IPMI and Internal communication (TWI type preferred)
ADC inputs for sensors
Min 16KByte of Flash Memory (64 Kbyte if HPM update shall be used)
EEPROM for storage of non-volatile data (sensor thresholds, min/max values)

The MMC Design Package implements all mandatory sensors such as temperature, voltage and hot swap sensors, and complies with the following specifications:

IPMI
PICMG 3.0
AMC.0
HPM.1

Other optional sensors can be easily added to the source code using the well defined interfaces.

Package content and royalty-free perpetual source or object code license

The MMC Design Package consists of:

a royalty-free and perpetual license for either source or object code for the MMC
hardware reference schematics for the MMC circuitry
a bill of material of all components necessary to build the MMC circuitry
documentation and manual

The source code of the MMC firmware is entirely written in the "C" programming language and can be easily compiled using the tool chain from Atmel.

For customers wanting to implement a standard MMC without any code modifications an object license of the MMC code is available as well. Custom adaptions of AMC specifc parameters such as product name, serial number etc (aka as FRU Record) can be edited using standard tools like ipmitool or NATview.

Reference platform in AMC form factor

With the NAMC-MMC-REF N.A.T. has designed a reference platform in the AMC form factor which is strictly based on the MMC Design Package. In order to save time and costs, customers can use the NAMC-MMC-REF to develop and test their own MMC based on the MMC Design Package in parallel to the hardware design process and thus even before their own hardware becomes available.
