FPGA Master Serial Mode Summary
The I/O and logic functions of the FPGA and their associ-
ated interconnections are established by a configuration
program. The program is loaded either automatically upon
power-up, or on command, depending on the state of the
FPGA mode pins. In Master Mode, the FPGA automatically
loads the configuration program from an external memory.
The AT17 Serial Configuration EEPROM has been
designed for compatibility with the Master Serial Mode.
This document discusses the AT6000 FPGA interface. For
more details or AT40K FPGA applications, please refer-
ence “AT6000 Series Configuration” or “AT40K Series
Configuration” application notes.
Controlling the Low-density AT17
Series Serial EEPROMs During
Configuration
Most connections between the FPGA device and the AT17
Serial EEPROM are simple and self-explanatory.

• The CEO output of any AT17C/LV128/256 drives the CE

There are two different ways to use the inputs CE and OE.
Condition 1
The simplest connection is to have the FPGA CON pin
drive both CE and RESET/OE
to its simplicity, however, this method will fail if the FPGA
receives an external reset condition during the configura-
tion cycle. If a system reset is applied to the FPGA, it will
abort the original configuration and then reset itself for a
new configuration, as intended. Of course, the AT17 Series
Configurator does not see the external reset signal and will
not reset its internal address counters and, consequently,
will remain out of sync with the FPGA for the remainder of
the configuration cycle.

of a cascade chain or as a standalone device.
