The Xilinx XC9572XL-10VQG64I is a 72-macrocell CPLD from the XC9500XL family, offering 1,600 usable gates and 52 I/Os in a 64-pin VQFP package measuring 10 x 10 mm. 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 100 MHz. The suffix “I” indicates industrial temperature range, making this device suitable for applications where commercial-grade devices would be inadequate.

Industrial Temperature Grade

Unlike commercial-grade devices that are specified only from 0°C to 70°C, the XC9572XL-10VQG64I is characterised for operation from –40°C to 85°C (ambient temperature). This extended range is critical for applications in outdoor enclosures, unheated industrial environments, automotive systems (non-engine compartment), telecom outdoor cabinets, and any equipment subject to wide temperature swings.

Architecture

The XC9572XL is based on FastFLASH technology, providing in-system programmability with a minimum of 10,000 program/erase cycles. The device consists of four 54V18 function blocks, each containing 18 macrocells. The 52 I/O pins are distributed across the 64-pin VQFP package. The interconnect matrix between function blocks ensures predictable timing and high logic utilisation. The I/O pins are 5V tolerant, accepting 5V, 3.3V, and 2.5V signals, with configurable 3.3V or 2.5V output levels.

Key Features

• Fast concurrent programming for efficient production programming
• Slew rate control on individual outputs to reduce electromagnetic interference
• Three global clocks and one product-term clock with local clock inversion
• In-system programmable with 10,000 program/erase cycles minimum
• Individual macrocell low-power mode option

Power Considerations

Power dissipation in the XC9500XL family varies with system frequency, design complexity, and output loading. Each macrocell can be individually configured for low-power mode to reduce static power consumption. Unused product terms and macrocells are automatically deactivated by the development software. In industrial temperature applications where the device may be exposed to high ambient temperatures, proper thermal management should be considered.

Packaging and Environmental

The XC9572XL-10VQG64I is housed in a 64-pin VQFP (Very Thin Quad Flat Pack) package measuring 10 x 10 mm with a 0.5 mm pitch. The package is RoHS compliant (RoHS3) and REACH unaffected. Moisture Sensitivity Level is MSL 3, requiring a floor life of 168 hours after opening. The device is supplied in tray packaging. EAN: 4099879145710.

Development Support

Supported by Xilinx ISE WebPACK and ISE Design Suite (ISE 14.7). Programmable via JTAG (IEEE 1149.1) using standard cables. The device is not supported by the newer Vivado toolchain. For new designs requiring industrial temperature range and similar density, consider the Xilinx CoolRunner-II family.

Product Status

The XC9572XL-10VQG64I 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.
