Product Specification
Introduction
The Spartan
family of PROMs provides an easy-to-use,
cost-effective method for storing Spartan device configura-
tion bitstreams.
When the Spartan device is in Master Serial mode, it gener-
ates a configuration clock that drives the Spartan PROM. A
short access time after the rising clock edge, data appears
on the PROM DATA output pin that is connected to the Spar-
tan device D
IN
pin. The Spartan device generates the
appropriate number of clock pulses to complete the config-
uration. Once configured, it disables the PROM. When a
Spartan device is in Slave Serial mode, the PROM and the
Spartan device must both be clocked by an incoming signal.
For device programming, either the Xilinx Alliance or the
Foundation series development systems compiles the Spar-
tan device design file into a standard HEX format which is
then transferred to most commercial PROM programmers.

Pin Description
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.
Each rising edge on the CLK input increments the internal address counter, if both
CE and OE are active.
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.

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

Controlling PROMs
Connecting the Spartan device with the PROM:
The DATA output of the PROM drives the D
IN
input of
the lead Spartan device.
The Master Spartan device CCLK output drives the
CLK input of the PROM.
The RESET/OE input of the PROM is driven by the
INIT output of the Spartan device. This connection
assures that the PROM address counter is reset before
the start of any (re)configuration, even when a
reconfiguration is initiated by a V
CC
glitch. Other
methods—such as driving RESET/OE from LDC or
system reset—assume that the PROM internal
power-on-reset is always in step with the FPGAs
internal power-on-reset, which may not be a safe
assumption.
The CE input of the PROM is driven by the DONE
output of the Spartan device, provided that DONE is
not permanently grounded. Otherwise, LDC can be
used to drive CE, but must then be unconditionally
High during user operation. CE can also be
permanently tied Low, but this keeps the DATA output
active and causes an unnecessary supply current of
10 mA maximum.
FPGA Master Serial Mode Summary
The I/O and logic functions of the Configurable Logic Block
(CLB) and their associated 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 Spartan device MODE pin. In Master
Serial mode, the Spartan device automatically loads the
configuration program from an external memory. The Spar-
tan PROM has been designed for compatibility with the
Master Serial mode.
Upon power-up or reconfiguration, the Spartan device
enters the Master Serial mode when the MODE pin is Low.
Data is read from the PROM sequentially on a single data
line. Synchronization is provided by the rising edge of the
temporary signal CCLK, which is generated during configu-
ration.

unchanged after configuration is complete. Therefore, to
reprogram the FPGA with another program, the DONE line
is pulled Low and configuration begins at the last value of
the address counters.
This method fails if a user applies RESET during the Spar-
tan device configuration process. The Spartan device
aborts the configuration and then restarts a new configura-
tion, as intended, but the PROM does not reset its address
counter, since it never saw a High level on its OE input. The
new configuration, therefore, reads the remaining data in
the PROM and interprets it as preamble, length count etc.
Since the Spartan device is the Master, it issues the neces-
sary number of CCLK pulses, up to 16 million (2
24
) and
DONE goes High. However, the Spartan device configura-
tion will be completely wrong, with potential contentions
inside the Spartan device and on its output pins. This
method must, therefore, never be used when there is any
chance of external reset during configuration.
Master Serial mode provides a simple configuration inter-
face (Figure
1).
Only a serial data line and two control lines
are required to configure the Spartan device. Data from the
PROM is read sequentially, accessed via the internal
address and bit counters which are incremented on every
valid rising edge of CCLK.
If the user-programmable, dual-function D
IN
pin on the
Spartan device is used only for configuration, it must still be
held at a defined level during normal operation. The Spar-
tan family takes care of this automatically with an on-chip
default pull-up resistor.
Programming the FPGA With Counters
Unchanged Upon Completion
When multiple-configurations for a single Spartan device
are stored in a PROM, the OE pin should be tied Low. Upon
power-up, the internal address counters are reset and con-
figuration begins with the first program stored in memory.
Since the OE pin is held Low, the address counters are left

Standby Mode
The PROM enters a low-power standby mode whenever CE
is asserted High. The output remains in a high-impedance
state regardless of the state of the OE input.
Programming the Spartan Family
PROMs
The devices can be programmed on programmers supplied
by Xilinx or qualified third-party vendors. The user must
ensure that the appropriate programming algorithm and the
latest version of the programmer software are used. The
wrong choice can permanently damage the device.
