AT17A Series Reset Polarity
The AT17A series configurator allows the user to program the polarity of the RESET/OE pin as
either RESET/OE or RESET/OE. This feature is supported by industry-standard programmer
algorithms.
9.
Programming Mode
The programming mode is entered by bringing SER_EN Low. In this mode the chip can be pro-
grammed by the 2-wire serial bus. The programming is done at V
CC supply only. Programming
super voltages are generated inside the chip.
10. Standby Mode
The AT17LV65A/128A/256A enters a low-power standby mode whenever nCS is asserted High.
In this mode, the configurator consumes less than 50 A of current at 3.3V (100 A for the
AT17LV512A/010A/002A). The output remains in a high-impedance state regardless of the state
of the RESET/OE input.

age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those listed under oper-
ating conditions is not implied. Exposure to Abso-
lute Maximum Rating conditions for extended
periods of time may affect device reliability.
