VADJ_FMC Power Rail
The ZCU216 evaluaon board implements the ANSI/VITA 57.1 secon 5.5.1 IPMI support
funconality. The power control of the VADJ_FMC power rail is managed by the U38 system
controller. This rail powers the FMCP HSPC (J28) VADJ pins, as well as the ZU49DR HP banks 66
and 67. The valid values of the VADJ_FMC rail are 1.2V, 1.5V, and 1.8V.
At power On, the system controller detects if an FMC module is installed on J28:
• If no card is aached to the FMCP connector, the VADJ voltage is set to 1.8V.
• When an FMC card is aached, its IIC EEPROM is read to nd a VADJ voltage supported by
both the ZCU216 board and the FMC module, within the available choices of 0.0V, 1.2V, 1.5V,
and 1.8V.
• If no valid informaon is found in an FMC card IIC EEPROM, the VADJ_FMC rail is set to 0.0V.
The system controller user interface allows the FMC IPMI roune to be overridden and an
explicit value can be set for the VADJ_FMC rail. Override mode is useful for FMC mezzanine
cards that do not contain valid IPMI EPROM data dened by the ANSI/VITA57.1 specicaon.
ZCU216 MSP430 System Controller
[Figure 2, callout 19]
The ZCU216 board includes an on-board MSP430 (U38) with integrated Power Advantage demo
and System Controller rmware. A Host PC resident system controller board user interface is
provided on the ZCU216 documentaon web page. The board user interface enables you to
query and control select programmable features such as clocks, FMC funconality, and power
system parameters. The ZCU216 web page also includes the ZCU216 System Controller GUI
Tutorial (XTP_TBD) and ZCU216 Soware Install and Board Setup Tutorial (XTP_TBD).
