Nonvolatile Memory
The internal EEPROM consists of a 5-bit nonvolatile
register that retains the value written to it before the
device is powered down. The nonvolatile register is
programmed with the zeros at the factory. Wait a mini-
mum of 12ms after writing to NVREG before sending
another command.
Power-Up
Upon power-up, the MAX5432–MAX5435 load the data
stored in the nonvolatile memory register into the
volatile memory register, updating the wiper position
with the data stored in the nonvolatile memory register.
This initialization period takes 20μs.
Standby
The MAX5432–MAX5435 feature a low-power standby
mode. When the device is not being programmed, it
goes into standby mode and current consumption is
typically 0.5μA.
