Key Features

• Spartan-3 FPGA Core  Built on the AMD Spartan®-3 family providing 1,728 logic elements for implementing custom digital logic and control functions.
• Embedded Memory  Approximately 0.074 Mbits of on-chip RAM (73,728 bits) to support buffering, small data stores, and state machines.
• I/O and Gate Count  Up to 63 I/Os and a gate-equivalent count of 50,000 to support moderate peripheral interfacing and glue-logic tasks.
• Low-Voltage Supply  Operates from 1.14 V to 1.26 V, enabling integration into low-voltage system power rails.
• Package and Mounting  100-TQFP (supplier package: 100-VQFP 14×14) surface-mount package for compact PCB layouts and automated assembly.
• Industrial Temperature Grade  Rated for operation from −40 °C to 100 °C, suitable for industrial environments.
• RoHS Compliant  Meets RoHS environmental requirements for lead-free assembly.

Typical Applications

• Industrial Control  Use the industrial temperature rating and 63 I/Os to implement sensor interfacing, control logic, and field I/O aggregation in industrial equipment.
• Embedded Logic and Glue  Deploy as programmable glue logic or protocol bridging where 1,728 logic elements and on-chip RAM handle control paths and small buffering needs.
• Prototyping and Evaluation  The compact 100-TQFP surface-mount package and moderate logic density make it suitable for board-level prototyping and evaluation of custom digital functions.

Unique Advantages

• Balanced Logic and Memory: Combines 1,728 logic elements with 73,728 bits of embedded RAM, offering a practical balance for control-oriented and moderate DSP tasks.
• Industrial-Grade Reliability: Rated from −40 °C to 100 °C and specified as industrial grade for use in temperature-challenging environments.
• Compact, Surface-Mount Package: 100-TQFP (14×14) package supports dense PCB layouts and standard surface-mount assembly processes.
• Low-Voltage Operation: Narrow core supply range (1.14 V–1.26 V) supports integration with modern low-voltage power domains.
• Regulatory Compliance: RoHS compliance supports lead-free manufacturing requirements.
