XC3S50-4TQG144I

The XC3S50-4TQG144I is a Spartan®-3 Field Programmable Gate Array (FPGA) from AMD provided in a 144-pin LQFP package. It delivers a compact, industrial-grade programmable logic resource with a defined set of logic elements, on-chip RAM and I/O suitable for embedded and industrial applications.

With 1,728 logic elements, approximately 0.074 Mbits of embedded memory and 97 user I/O pins, this device targets designs that require moderate logic capacity, on-chip storage and a wide operating temperature range for reliable operation in industrial environments.

Key Features

• Core Logic  Contains 1,728 logic elements supporting user-defined digital logic and up to 50,000 equivalent gates for custom implementations.
• On-chip Memory  Approximately 0.074 Mbits (73,728 bits) of embedded RAM to support buffering, state storage and small lookup tables within the FPGA fabric.
• I/O Density  Provides 97 user I/O pins for interfacing to external peripherals, sensors and digital buses.
• Package and Mounting  Available in a 144-LQFP package (supplier device package: 144-TQFP, 20×20) and designed for surface-mount assembly.
• Power  Core voltage supply range from 1.14 V to 1.26 V for the programmable fabric.
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C, suitable for thermal conditions encountered in industrial deployments.
• Standards Compliance  RoHS-compliant construction for materials and manufacturing processes.

Typical Applications

• Industrial Control  Programmable logic and on-chip memory allow implementation of control algorithms, timing logic and interface glue in industrial equipment operating across a broad temperature range.
• Embedded I/O Aggregation  With 97 I/O pins, the device can consolidate multiple digital signals and custom protocols for embedded systems and sensor interfaces.
• Custom Logic Acceleration  Support for approximately 50,000 gates and 1,728 logic elements enables offloading of dedicated logic functions from microcontrollers or processors.

Unique Advantages

• Compact, package-ready solution: The 144-LQFP (144-TQFP, 20×20) package and surface-mount mounting simplify PCB layout for space-constrained designs.
• Industrial-rated operation: Specified operation from −40 °C to 100 °C supports deployment in industrial environments requiring extended temperature tolerance.
• Balanced logic and memory: The combination of 1,728 logic elements and approximately 0.074 Mbits of embedded RAM supports mid-range logic implementations with on-chip storage.
• High I/O count: Ninety-seven user I/O pins enable flexible interfacing to external devices, sensors and bus systems without excessive board-level multiplexing.
• Regulatory-friendly materials: RoHS compliance reduces material restrictions and supports global manufacturing requirements.
