Programming voltage
VTRIP programed voltage range
Initial VTRIP program voltage accuracy (VCC applied-VTRIP) (programmed at 25°C)
Subsequent VTRIP Program Voltage accuracy [(VCC applied-Vta1)-VTRIP]
(programmed at 25°C)
Vtr
VTRIP Program Voltage repeatability (successive program operations)
(programmed at 25°C)
Vtv
