XC3S50-4TQ144I

The XC3S50-4TQ144I is a Spartan®-3 Field Programmable Gate Array (FPGA) IC from AMD. It provides 1,728 logic elements, approximately 73,728 bits of on-chip RAM, and 97 user I/O in a 144-LQFP package.

Designed for industrial-temperature operation and surface-mount deployment, this device supports a core supply range of 1.14 V to 1.26 V and is RoHS compliant.

Key Features

• Core Logic  1,728 logic elements enable configurable digital logic implementation for custom functions.
• Embedded Memory  Approximately 0.074 Mbits of on-chip RAM (73,728 bits) for data buffering and small lookup tables.
• I/O Capacity  97 user I/O pins provide flexible interfacing options within the 144-LQFP package footprint.
• Gate Count  Approximately 50,000 gates for a balance of integration density and design flexibility.
• Power  Core supply voltage range of 1.14 V to 1.26 V supports low-voltage system integration.
• Package & Mounting  144-LQFP package (supplier device package: 144-TQFP 20×20) in a surface-mount form factor for PCB assembly.
• Temperature & Grade  Industrial-grade device with an operating temperature range of −40 °C to 100 °C for deployment in demanding environments.
• Compliance  RoHS compliant.

Typical Applications

• General-purpose programmable logic  Implement custom digital functions and glue logic using the device's 1,728 logic elements and on-chip RAM.
• Interface consolidation  Use the device's 97 I/O to aggregate and adapt signals between subsystems within a 144-LQFP footprint.
• Industrial embedded systems  Deploy in industrial-temperature environments where the −40 °C to 100 °C operating range and surface-mount package are required.

Unique Advantages

• Compact programmable solution: The combination of 1,728 logic elements and approximately 0.074 Mbits of embedded RAM provides a small, reconfigurable logic engine for space-constrained designs.
