The Xilinx XC95288XL-10TQG144C is the largest member of the XC9500XL CPLD family, offering 288 macrocells and 6,400 usable gates in a 144-pin TQFP package. Built on 0.35 µm CMOS FastFLASH technology and operating at 3.3 V, it delivers a 10 ns pin-to-pin delay and a system frequency of up to 208 MHz. This device is designed for high-performance, low-voltage applications in communications, computing, and industrial systems where high logic density and predictable timing are critical.

Architecture

The XC95288XL is comprised of 16 54V18 function blocks, each containing 18 macrocells, for a total of 288 macrocells. The FastCONNECT II switch matrix interconnects all function block outputs and input signals, providing superior pin-locking and routability. The I/O blocks provide buffering for 117 user I/O pins in the 144-pin TQFP package. The I/O pins are 5V tolerant, accepting 5V, 3.3V, and 2.5V signals, with configurable 3.3V or 2.5V output levels.

Speed Grade -10

The -10 speed grade indicates a maximum pin-to-pin propagation delay of 10 ns. The internal system frequency can reach up to 208 MHz. For applications requiring higher performance, the -7 speed grade (6 ns delay) is also available within the XC9500XL family, though the -10 grade provides a balanced trade-off between speed and power consumption for most high-density designs.

Key Features

• Fast concurrent programming via JTAG
• Slew rate control on individual outputs to reduce switching noise
• Three global clocks and one product-term clock with local clock inversion
• Bus-hold circuitry on all user pin inputs
• In-system programmable with 10,000 program/erase cycles minimum

Power Considerations

Power dissipation in the XC9500XL family varies substantially with system frequency, design application, and output loading. Each macrocell can be individually configured for low-power mode (default is high-performance mode) to reduce static power consumption. Unused product terms and macrocells are automatically deactivated by the Xilinx ISE development software, further conserving power.

Packaging and Environmental

The XC95288XL-10TQG144C is housed in a 144-pin TQFP (Thin Quad Flat Pack) package measuring 20 x 20 mm with a 0.5 mm pitch. The package is RoHS compliant (RoHS3) and REACH compliant. Moisture Sensitivity Level is MSL 3, requiring a floor life of 168 hours after opening. The device is supplied in tray packaging with 60 pieces per tray. EAN: 4099879145697.

Development Support

The XC9500XL family is supported by Xilinx ISE WebPACK and ISE Design Suite (final release: ISE 14.7). Programmable via JTAG (IEEE 1149.1) using standard cables such as the Xilinx Platform Cable USB or third-party programmers. The device is not supported by the newer Vivado toolchain. For new designs, consider newer CPLD families such as CoolRunner-II or Artix-7 FPGAs.

Product Status

The XC95288XL-10TQG144C is marked as obsolete by DigiKey. Stock is limited and the device is no longer in active production. For existing designs, verify supply availability before committing to volume production.
