Controlling The High-Density AT17 Series Serial EEPROMs
Most connections between the FPGA device and the Serial
EEPROM are simple and self-explanatory:
The DATA output of the high-density AT17 Series drives
DIN of the FPGA devices.
The master FPGA CCLK output drives the CLK input of
the high-density AT17 Series.
The CEO output of any AT17C/LV512/010 drives the CE
input of the next AT17C/LV512/010 in a cascade chain of
PROMs.
SER_EN must be connected to V
CC
, (except during
ISP).
READY is available as an open-collector indicator of the
device’s RESET status; it is driven Low while the device is
in its POWER-ON RESET cycle and released (tri-stated)
when the cycle is complete.
There are two different ways to use the inputs CE and OE,
as shown in the AC Characteristics waveforms.
Condition 1
The simplest connection is to have the FPGA D/P output
drive both CE and RESET/OE in parallel (Figure 1). Due 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 high-density
AT17 Series 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.
Condition 2
The FPGA D/P output drives only the CE input of the high-
density AT17 Series, while its OE input is driven by the
inversion of the input to the FPGA RESET input pin. This
connection works under all normal circumstances, even
when the user aborts a configuration before D/P has gone
High. A High level on the RESET/OE input to the
AT17C/LVxxx – during FPGA reset – clears the Configura-
tor’s internal address pointer, so that the reconfiguration
starts at the beginning. The high-density AT17 Series does
not require an inverter since the RESET polarity is pro-
grammable.
