V
I/O voltage for eFuse burning
NOTE: If the VHV voltage is higher 
than VDD voltage (burning 
mode), VDD must be 
powered before VHV, to 
prevent the fuse from being 
accidentally burned.
VHV (during eFuse 
Reading mode)
0.95

V
I/O voltage for eFuse reading
NOTE: It is recommended that if 
only a read operation is 
required, VHV would be 
connected to the device 
VDD power.
