Features
Description
•
One-time programmable (OTP) read-only memory
designed to store configuration bitstreams of Xilinx
FPGA devices
The XC1700 family of configuration PROMs provides an
easy-to-use, cost-effective method for storing large Xilinx
FPGA configuration bitstreams.
•
Simple interface to the FPGA; requires only one user
I/O pin
•
Cascadable for storing longer or multiple bitstreams
•
Programmable reset polarity (active High or active
Low) for compatibility with different FPGA solutions
•
XC17128E/EL, XC17256E/EL, XC1701 and XC1700L
series support fast configuration
When the FPGA is in Master Serial mode, it generates a
configuration clock that drives the PROM. A short access
time after the rising clock edge, data appears on the PROM
DATA output pin that is connected to the FPGA DIN pin. The
FPGA generates the appropriate number of clock pulses to
complete the configuration. Once configured, it disables the
PROM. When the FPGA is in Slave Serial mode, the PROM
and the FPGA must both be clocked by an incoming signal.
•
Low-power CMOS Floating Gate process
•
XC1700E series are available in 5V and 3.3V versions
•
XC1700L series are available in 3.3V only
•
Available in compact plastic packages: 8-pin SOIC,
8-pin VOIC, 8-pin PDIP, 20-pin SOIC, 20-pin PLCC,
44-pin PLCC or 44-pin VQFP.

Pin Description
VPP
DATA
Data output is in a high-impedance 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.
Programming voltage. No overshoot above the specified
max voltage is permitted on this pin. For normal read operation, this pin must be connected to VCC. Failure to do so
may lead to unpredictable, temperature-dependent operation and severe problems in circuit debugging. Do not leave
VPP floating!
CLK
VCC and GND
Each rising edge on the CLK input increments the internal
address counter, if both CE and OE are active.
Positive supply and ground pins.
PROM Pinouts
RESET/OE
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 "0", and puts the DATA output 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.

Chip Enable output, to be connected to the CE input of the
next PROM 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.

Notes:
1. The suggested PROM is determined by compatibility with the
higher configuration frequency of the Xilinx FPGA CCLK.
Designers using the default slow configuration frequency
(CCLK) can use the XC1765E or XC1765EL for the noted
FPGA devices.

Controlling PROMs
read sequentially, accessed via the internal address and bit
counters which are incremented on every valid rising edge
of CCLK.
Connecting the FPGA device with the PROM.
•
The DATA output(s) of the of the PROM(s) drives the
DIN input of the lead FPGA device.
•
The Master FPGA CCLK output drives the CLK input(s)
of the PROM(s).
•
The CEO output of a PROM drives the CE input of the
next PROM in a daisy chain (if any).
•
The RESET/OE input of all PROMs is best driven by
the INIT output of the lead FPGA 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 VCC glitch.
Other methods—such as driving RESET/OE from LDC
or system reset—assume the PROM internal
power-on-reset is always in step with the FPGA’s
internal power-on-reset. This may not be a safe
assumption.
•
•
The PROM CE input can be driven from either the LDC
or DONE pins. Using LDC avoids potential contention
on the DIN pin.
The CE input of the lead (or only) PROM is driven by
the DONE output of the lead FPGA 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 three FPGA mode pins. In Master Serial
mode, the FPGA automatically loads the configuration program from an external memory. The Xilinx PROMs have
been designed for compatibility with the Master Serial
mode.
Upon power-up or reconfiguration, an FPGA enters the
Master Serial mode whenever all three of the FPGA
mode-select pins are Low (M0=0, M1=0, M2=0). 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 configuration.
Master Serial Mode provides a simple configuration interface. Only a serial data line and two control lines are
required to configure an FPGA. Data from the PROM is
4
If the user-programmable, dual-function DIN pin on the
FPGA is used only for configuration, it must still be held at a
defined level during normal operation. The Xilinx FPGA
families take care of this automatically with an on-chip
default pull-up resistor.
Programming the FPGA With Counters
Unchanged Upon Completion
When multiple FPGA-configurations for a single FPGA are
stored in a PROM, the OE pin should be tied Low. Upon
power-up, the internal address counters are reset and configuration begins with the first program stored in memory.
Since the OE pin is held Low, the address counters are left
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 FPGA
configuration process. The FPGA aborts the configuration
and then restarts a new configuration, 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 FPGA is
the master, it issues the necessary number of CCLK pulses,
up to 16 million (224) and DONE goes High. However, the
FPGA configuration will be completely wrong, with potential
contentions inside the FPGA and on its output pins. This
method must, therefore, never be used when there is any
chance of external reset during configuration.
Cascading Configuration PROMs
For multiple FPGAs configured as a daisy-chain, or for
future FPGAs requiring larger configuration memories, cascaded PROMs provide additional memory. After the last bit
from the first PROM is read, the next clock signal to the
PROM asserts its CEO output Low and disables its DATA
line. The second PROM recognizes the Low level on its CE
input and enables its DATA output. See Figure 2.
After configuration is complete, the address counters of all
cascaded PROMs are reset if the FPGA RESET pin goes
Low, assuming the PROM reset polarity option has been
inverted.
To reprogram the FPGA with another program, the DONE
line goes Low and configuration begins where the address
counters had stopped. In this case, avoid contention
between DATA and the configured I/O use of DIN.

Programming
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.
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.
