XC95144XL-7TQ144C

The AMD XC95144XL-7TQ144C is a high-performance complex programmable logic device (CPLD) from the XC9500XL family, designed by AMD (formerly Xilinx) for logic integration and glue logic functions in digital systems. Fabricated on a 0.35-micron CMOS process, it provides 144 macro cells and 3,200 usable gates, supporting system speeds up to 125 MHz with a 3.3V internal supply. The 144-pin TQFP package offers a compact surface-mount footprint with 117 user I/O pins, and the architecture delivers pin-to-pin logic delays as low as 7.5 nanoseconds, making it suitable for high-speed decoding, state machine implementation, and interface bridging where deterministic timing is critical.

Typical applications span industrial automation, communications infrastructure, and aerospace test equipment where in-system reprogrammability and non-volatile configuration streamline development. The device often serves as a programmable companion to microcontrollers or DSPs, managing address decoding, bus arbitration, and protocol adaptation in embedded control systems. Procurement professionals should note that this commercial-grade (0°C to +70°C) variant is widely available, while industrial temperature range versions (XC95144XL-7TQ144I) exist for demanding environments. As a mature product on a legacy process node, the XC9500XL family benefits from long-term supply commitments, but design teams must monitor AMD’s lifecycle notices for potential obsolescence scheduling, and plan qualification of alternative sources where permissible to mitigate end-of-life risk.
