XC6SLX4-3TQG144I

The XC6SLX4-3TQG144I is a Spartan®-6 LX field programmable gate array (FPGA) in a 144-lead LQFP package. It combines a mid-range logic capacity with embedded memory and a broad I/O count to address industrial and embedded digital design needs.

With 3,840 logic elements and approximately 0.22 Mbits of on-chip RAM, this industrial-grade FPGA supports designs that require moderate logic density, configurable I/O and a compact surface-mount package footprint.

Key Features

• Core Logic  3,840 logic elements and 300 CLBs provide the configurable fabric for custom digital logic and state machines.
• Embedded Memory  Approximately 0.22 Mbits of on-chip RAM for data buffering, small FIFOs and distributed storage.
• I/O  102 user I/O pins to support multiple peripheral interfaces and board-level signal routing.
• Power  Core voltage supply range from 1.14 V to 1.26 V for the device core power domain.
• Package & Mounting  Available in a 144-LQFP (supplier device package: 144-TQFP, 20×20) surface-mount package for compact PCB designs.
• Temperature & Grade  Industrial grade with an operating temperature range of −40 °C to 100 °C to meet harsher environment requirements.
• Compliance  RoHS compliant.

Typical Applications

• Industrial control systems  Implement custom control logic and signal processing using the device’s 3,840 logic elements and industrial temperature rating.
• Embedded system prototyping  Rapidly develop and iterate hardware functions that need configurable logic and on-chip RAM in a small LQFP footprint.
• Interface bridging and I/O expansion  Use the 102 I/O pins to create custom protocol bridges, level translation logic, or board-level interface consolidation.

Unique Advantages

• Balanced logic and memory  3,840 logic elements paired with approximately 0.22 Mbits of RAM offers a practical balance for mid-range FPGA designs.
• Significant I/O capacity  102 user I/Os enable flexible connectivity for sensors, peripherals and custom interfaces without large packages.
• Industrial operating range  Rated for −40 °C to 100 °C operation to support deployment in temperature-challenging environments.
• Compact surface-mount package  144-LQFP (144‑TQFP 20×20) delivers a small PCB footprint while retaining ample I/O and routing resources.
• RoHS compliant  Meets RoHS directives for environmentally conscious designs.
