Pin Description
DATA 1 1
Data output, High-Z state when either CE
or OE are inactive. During
programming, the DATA pin is I/O. Note that OE
can be programmed to be either
active High or active Low.
CLK 2 3
Each rising edge on the CLK input increments the internal address counter, if both
CE
and OE are active.
RESET/OE
(OE/RESET
)
38
When High, this input holds the address counter reset and puts the DATA output
in a high-impedance state. The polarity of this input pin is programmable as either
RESET/OE
or OE/RESET. To avoid confusion, this document describes the pin
as RESET/OE
, although the opposite polarity is possible on all devices. When
RESET is active, the address counter is held at zero, and the DATA output is in a
high-impedance state. The polarity of this input is programmable. The default is
active High RESET, but the preferred option is active Low RESET
, because it can
be driven by the FPGAs INIT
pin.
The polarity of this pin is controlled in the programmer interface. This input pin is
easily inverted using the Xilinx HW-130 programmer software. Third-party
programmers have different methods to invert this pin.
CE
410
When High, this pin disables the internal address counter, puts the DATA output
in a high-impedance state, and forces the device into low-I
CC
standby mode.
GND 5 11 GND is the ground connection.
