Speed Grade

Zynq UltraScale plus MPSoC Power Management

Release Date

ZU+ devices are available in speed-grades that can work with the PL at lower voltages of 0.72V when compared to the nominal 0.85V devices. As discussed earlier, operating at a lower voltage helps in reducing both static and dynamic power consumption significantly. So, for applications having stringent power goals, these low power variants need to be considered.

For example, on a ZU7EV device, using a -2L device instead of a -2 device, and bringing down PL voltage to 0.72V, can save around 20% of total power consumption.

ZU+ devices are available in -1L and -2L grades which are low power variants of -1 and -2 speed grades respectively. Refer to Zynq UltraScale+ MPSoC product selection guide for more details.
