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:
Package content and royalty-free perpetual source or object code license The MMC Design Package consists of:
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. |
