Pin Description
DATA
Data output, 3-stated 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
Each rising edge on the CLK input increments the internal
address counter, if both CE and OE are active.
RESET/OE
When High, this input holds the address counter reset and
3-states the DATA output. 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 3-stated. 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 FPGA’s INIT pin.
The polarity of this pin is controlled in the programmer inter-
face. This input pin is easily inverted using the Xilinx HW-
130 Programmer. Third-party programmers have different
methods to invert this pin.
CE
When High, this pin disables the internal address counter,
3-states the DATA output, and forces the device into low-I
standby mode.
CEO
Chip Enable output, to be connected to the CE input of the
next SCP in the daisy chain. This output is Low when the
CE and OE inputs are both active AND the internal address
counter has been incremented beyond its Terminal Count
(TC) value. In other words: when the PROM has been read,
CEO will follow CE as long as OE is active. When OE goes
inactive, CEO stays High until the PROM is reset. Note that
OE can be programmed to be either active High or active
Low.
V
Programming voltage. No overshoot above the specified
max voltage is permitted on this pin. For normal read oper-
ation, this pin must be connected to V
may lead to unpredictable, temperature-dependent opera-
tion and severe problems in circuit debugging. Do not leave
VPP floating!
V
Positive supply and ground pins.
