DESY MMC System on Module

The DESY MMC System on Module is a small stamp-sized (25.5x29x2.3 mm) component which can be mounted on top or bottom side of any AMC card.
The stamp provides a complete hardware and firmware solution to manage the target board including power system, FPGAs, JTAG and RTM. It fully supports in-system update via IPMI.

For basic operation no external components are required (except handle and LEDs). The board is a drop-in solution with minimal design effort and no additional development required. The module complete JTAG arbitration for up to two FPGAs and two FMC modules. It allows JTAG access to all user components over the on-board connector or the
MTCA backplane (JSM support).

A fully assembled breakout board with the following features is available::
• 1/3 AMC format, compatible with MTCA.4 and MTCA.0
• RTM connector (Zone 3)
• DC/DC converter with PMBus™ manager
• Serial FLASH chip (image for payload FPGA)
• USB connector for command-line access (Virtual COM port)
• All LGA module pins are accessible on breakout section

  • Complete MicroTCA management on a single module
  • Ready-to-use solder-in component based on ARM Cortex®-M4 processor
  • Flexible CPLD for FPGA update and control (variable IO voltage)
  • Pre-programmed component with HPM Firmware-update support
Main Features
  • Full IPMI handling (MCH communication, LEDs,AMC/RTM power, FRU read/write)
  • 2kBit EEPROM with unique ID (MAC address)
  • Complete AMC power management via PmBus™
  • Board failure handling (over-current, overtemperature)
  • Supports two FPGA interfaces (custom interface voltage: 1.2V - 3.3V) including IPMI firmware update
  • Control of up to two FMC modules
  • Re-configurable JTAG chain management
  • USB virtual COM port for MMC and FPGAs
  • Pre-programmed firmware can be modified with optional SDK
  • Breakout Board available

FRUGY - FRU Generator YAML

MicroTCA Tech Lab has developed and open-sourced FRUGY, a FRU generator to build records from a YAML configuration file. Although DESY MMC Stamp comes pre-programmed with a FRU, FRUGY can be used to customize FRUs for your custom boards based on the MMC Stamp. FRUGY can also be used to generate a FRU for RTMs, compatible with DAMC-FMC1Z7IO and DAMC-FMC2ZUP.
