Example Circuits
Figure 1.
AT17 Series Device for Programming PSLI Devices
Notes:
1. Reset polarity must be set to active Low.
2. Use of the optional READY pin is not available on the AT17C/LV65/128/256 devices.
The FPGA CON/DONE output drives the CE input of the AT17 Series Configurator, while the RESET/OE input is driven by
the FPGA INIT pin. This connection works under all normal circumstances, even when the user aborts the configuration
before CON/DONE has gone High. A Low level on the RESET/OE input, during FPGA reset, clears the configurator
s inter-
nal address pointer so that the reconfiguration starts at the beginning.

Drop-In Replacement of XC17/ATT17 PROMs for Xilinx/Lucent FPGA Applications
Notes:
1. Reset polarity must be set to active Low.
2. Use of the optional READY pin is not available on the AT17C/LV65/128/256 devices.
3. An internal pull-up resistor is enabled here for DONE.
