The Xilinx XC9572XL-10TQG100I is the industrial‑temperature variant of the XC9500XL family, offering 72 macrocells and 1,600 usable gates in a 100‑pin TQFP package. Built on 0.35 µm CMOS technology and operating at 3.3 V, it delivers a 10 ns pin‑to‑pin delay while maintaining reliable operation across a wide temperature range of –40°C to 85°C. This makes it suitable for applications where commercial‑grade devices (0°C to 70°C) would be inadequate.

Industrial Temperature Grade
The suffix “I” in the part number indicates industrial temperature range. Unlike commercial‑grade devices that are specified only from 0°C to 70°C, the XC9572XL-10TQG100I 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, for a total of 72 macrocells. The 72 I/O pins are distributed across the 100‑pin TQFP package. The interconnect matrix between function blocks ensures predictable timing and high logic utilisation.

Speed Grade -10
The -10 speed grade indicates a maximum pin‑to‑pin propagation delay of 10 ns, with a system frequency of 100 MHz. This provides adequate performance for most glue logic, state machine, and control functions while maintaining reasonable power consumption. For applications requiring higher speed, the -7 speed grade (7.5 ns, 178 MHz) is available in commercial temperature grade only; industrial temperature users typically use the -10 grade or consider newer device families.

Key Features
The device supports fast concurrent programming for efficient production programming. Individual outputs can be configured with slew rate control to reduce electromagnetic interference (EMI). The clocking architecture includes three global clocks and one product‑term clock, with local clock inversion available on each macrocell. This flexibility allows the device to handle complex timing requirements.

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 (adequate airflow, heat sinking if necessary) should be considered.

Packaging and Environmental
The XC9572XL-10TQG100I is housed in a 100‑pin TQFP (Thin Quad Flat Pack) package measuring 14 × 14 mm with a 0.5 mm pitch. The package is RoHS compliant (Date of RoHS guidelines: March 31, 2015) and SVHC‑free. Moisture Sensitivity Level is MSL 3, requiring a floor life of 168 hours after opening. The device is supplied in tray packaging with 90 pieces per tray. Country of origin is Taiwan.

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 or AMD/Xilinx Artix‑7 FPGAs, which offer modern tool support and lower power consumption.

Typical Applications
The XC9572XL-10TQG100I is well‑suited for industrial control systems, factory automation equipment, outdoor telecommunications infrastructure, railway signalling and control, automotive infotainment and body control (non‑engine compartment), test and measurement equipment exposed to varying temperatures, and any embedded system requiring reliable logic integration across a wide temperature range. Its 72 macrocells provide sufficient density for glue logic, state machines, bus interfaces, and I/O expansion in industrial applications.
