WRITE/ERASE CYCLE ENDURANCE
and fabricated to meet advanced firmware storage re-
quirements. To ensure this level of reliability, V

cycles. For SmartVoltage-compatible production pro-
gramming, 12V V

hours. Operation outside these limits may reduce the
number of WRITE and ERASE cycles that can be per-
formed on the device.
POWER USAGE

read mode to conserve power. Deep power-down mode
is enabled by bringing RP# LOW. Current draw (I

the respective active power until the WRITE or ERASE
is completed.
