XC9500 In-System Programmable CPLD Family
Power-Up Characteristics
The XC9500 devices are well behaved under all operating
conditions. During power-up each XC9500 device employs
internal circuitry which keeps the device in the quiescent
state until the V
(approximately 3.8V). During this time, all device pins and
JTAG pins are disabled and all device outputs are disabled
with the IOB pull-up resistors (~10K ohms) enabled, as
shown in
level, all user registers become initialized (typically within
100 μs for 9536, 95144, 200 μs for 95216, and 300 μs for
95288), and the device is immediately available for opera-
tion, as shown in
If the device is in the erased state (before any user pattern
is programmed), the device outputs remain disabled with
the IOB pull-up resistors enabled. The JTAG pins are
enabled to allow the device to be programmed at any time.
If the device is programmed, the device inputs and outputs
take on their configured states for normal operation. The
JTAG pins are enabled to allow device erasure or bound-
ary-scan tests at any time.
Development System Support
The XC9500 CPLD family is fully supported by the develop-
ment systems available from Xilinx and the Xilinx Alliance
Program vendors.
The designer can create the design using ABEL, schemat-
ics, equations, VHDL, or Verilog in a variety of software
front-end tools. The development system can be used to

implement the design and generate a JEDEC bitmap which
can be used to program the XC9500 device. Each develop-
ment system includes JTAG download software that can be
used to program the devices via the standard JTAG inter-
face and a download cable.
FastFLASH Technology
An advanced CMOS Flash process is used to fabricate all
XC9500 devices. Specifically developed for Xilinx in-system
programmable CPLDs, the FastFLASH process provides
high performance logic capability, fast programming times,
and endurance of 10,000 program/erase cycles.
