ContributorT_ramp time question on Cyclone10 LP device
Hi ,
We use 10CL055YU484C8G. MSEL sets as Standard POR mode, datahseet reqiures ramping time of power supply to be within 50us~50ms.
Is this requirement apply for each single power rail's t_ramp or Total t_ramp time of all rail?
Thanks!
- Hi, Do you mean that the sum of all power rails' t_ramp should be within 50us-50ms? Yes

another question is , if the power rail ramps up too fast (<50us) or too slow(>50ms), what may happen? Thanks.
We now have a LDO desgined for VCCA_PLL_2V5 for 10CL055YU484C8G , whose ramp time is rather short, about 30us or so. That's is my worry.

Hi RSree,
