Notes:
AT17A Series Reset Polarity
The AT17A Series Configurator allows the user to program
the polarity of the OE pin as either RESET/OE or
RESET/OE. For more details, please reference the “Pro-
gramming Specification for Atmel’s FPGA Configuration
EEPROMs” application note.
Programming Mode
The programming mode is entered by bringing SER_EN
Low. In this mode the chip can be programmed by the
2-wire serial interface. The programming is done at V
supply only. Programming super voltages are generated

inside the chip. See the “Programming Specification for
Atmel’s Configuration EEPROMs” application note for fur-
ther information. The AT17 A-series parts are read/write at
5V nominal. The AT17LV A-series parts are read/write at
3.3V nominal.
Standby Mode
The AT17A Series Configurator enters a low-power
standby mode whenever nCS is asserted High. In this
mode, the configuration consumes less than 0.5 mA of cur-
rent at 5V. The output remains in a high-impedance state
regardless of the state of the OE input.
