XC3S400-4TQG144I

The XC3S400-4TQG144I is a Spartan®-3 field programmable gate array (FPGA) IC from AMD. It provides 8,064 logic elements and approximately 0.295 Mbits of embedded RAM in a 144-pin LQFP package, delivering programmable logic and on-chip memory for industrial applications.

With 97 user I/Os, a supply voltage range of 1.14 V to 1.26 V, and industrial operating temperature grading, this device is intended for designs that require moderate logic density and robust temperature performance.

Key Features

• Core Logic  8,064 logic elements and approximately 400,000 gates provide the programmable fabric for custom digital functions.
• Embedded Memory  Approximately 0.295 Mbits of on-chip RAM (294,912 bits) for data buffering, state storage, and small lookup tables.
• I/O Capability  97 user I/O pins support interfacing with peripherals and external components in a single-package solution.
• Power  Operates from a supply voltage range of 1.14 V to 1.26 V, enabling predictable power design within that window.
• Package & Mounting  144-LQFP (supplier package listed as 144-TQFP, 20×20) in a surface-mount form factor for PCB integration.
• Industrial Temperature Range  Rated for operation from -40°C to 100°C to meet demanding environmental conditions.
• RoHS Compliance  RoHS compliant for regulatory and environmental considerations.

Typical Applications

• Industrial Control Systems  Programmable logic and on-chip memory support control, sequencing, and I/O aggregation in industrial environments.
• Embedded System Prototyping  Provides a reconfigurable platform for developing and validating digital designs with moderate logic and memory needs.
• Interface and Glue Logic  Used to implement custom interfacing, protocol bridging, and timing adjustments between components.

Unique Advantages

• Moderate Logic Density: 8,064 logic elements enable implementation of a wide range of digital functions without external CPLDs or multiple FPGAs.
• On-Chip Memory: Approximately 0.295 Mbits of embedded RAM reduces reliance on external memory for small data buffering and state machines.
• Industrial Robustness: Rated -40°C to 100°C for deployment in temperature-challenging environments.
• Compact Surface-Mount Package: 144-LQFP footprint simplifies PCB layout for space-constrained designs while maintaining ample I/O count.
• Controlled Power Envelope: Operates within a defined 1.14 V to 1.26 V supply range for predictable power delivery and design integration.
• Regulatory Compliance: RoHS compliant to support environmental and regulatory requirements.
