• Logic Blocks  176 logic blocks (CLBs) for structured, reusable logic resources in system designs.
• Embedded Memory  Approximately 0.055 Mbits of embedded memory (55,296 bits) to support buffering, small FIFOs, and state storage.
• I/O Count  108 user I/O pins to interface with peripherals, sensors, and external devices.
• Gate Equivalent  Rated at 50,000 gates for sizing and integration planning in modest-complexity systems.
• Power  Core supply range of 1.14 V to 1.26 V, enabling low-voltage core operation consistent with the device family.
• Package & Mounting  144-LQFP (supplier device package listed as 144-TQFP, 20×20) in a surface-mount form factor for standard PCB assembly flows.
• Operating Temperature  Industrial temperature range from −40 °C to 100 °C for deployment in temperature-challenging environments.
• Environmental Compliance  RoHS-compliant construction.

Typical Applications

• Industrial Control  Use the device to implement control logic, protocol bridging, and real-time interface functions in industrial systems that require an extended temperature range.
• Embedded Systems  Integrate moderate-density custom logic and I/O handling for embedded applications and compact system designs.
• I/O Expansion & Interfacing  Leverage 108 I/O pins for aggregating and conditioning signals between processors, sensors, and peripherals.
• Prototyping & Low-Density Integration  Employ the FPGA for proof-of-concept designs and projects needing reprogrammable logic with modest memory and gate counts.

Unique Advantages

• Compact Logic Density: 1,584 logic elements enable integration of custom logic without large-area devices, helping reduce board space and BOM complexity.
• Embedded Memory On-Chip: Approximately 0.055 Mbits of RAM supports local buffering and small data structures without external memory.
• Ample I/O Count: 108 user I/Os provide flexible connectivity for mixed-signal interfaces, sensors, and external peripherals.
• Industrial Temperature Capability: Rated from −40 °C to 100 °C for reliable operation in harsh or variable-temperature environments.
• Surface-Mount 144-LQFP Package: Standard 144-pin LQFP packaging simplifies PCB layout and assembly using common surface-mount processes.
• RoHS Compliant: Environmentally compliant assembly suitable for regulated markets and supply chains.
