• I/O Density  131 user I/Os to support wide peripheral integration and multiple interfaces.
• Power Supply  Low-voltage core operation from 1.14 V to 1.26 V to match modern system power rails.
• Industrial Temperature Range  Qualified for –40 °C to 100 °C operation for deployment in industrial environments.
• Package & Mounting  208-BFQFP package (supplier device package: 208-PQFP, 28 × 28 mm) in a surface-mount form factor for compact PCB layouts.
• Standards & Compliance  RoHS-compliant construction for regulatory and environmental conformity.
• Family-Level Capabilities (per LatticeECP2 data sheet)  The LatticeECP2 family provides LUT-based logic, embedded block RAM, sysDSP blocks, PLLs/DLLs and flexible configuration options (family-level details available in the LatticeECP2 data sheet).

Typical Applications

• Industrial Control  Implement control logic, sensor aggregation and custom protocol handling using 21,000 logic elements and 131 I/Os.
• Embedded Systems  Use on-board RAM and configurable logic to consolidate glue logic, interface modules and state machines within compact boards.
• Communications & Interfaces  Deploy as a protocol bridge or peripheral controller where flexible I/O and deterministic logic are required.
• Imaging & Instrumentation  Local buffering and parallel I/O support mid-range data acquisition and preprocessing tasks.

Unique Advantages

• Balanced integration: Combines 21,000 logic elements with on-chip RAM to reduce external memory and discrete logic requirements.
• Industrial-ready thermal range: Specified for –40 °C to 100 °C, supporting deployment in harsh or temperature-variable environments.
• Compact OEM footprint: 208-pin BFQFP / 208-PQFP (28 × 28 mm) surface-mount package simplifies PCB routing for space-constrained designs.
• Low-voltage core: 1.14 V to 1.26 V supply compatibility aligns with contemporary system power architectures.
• Regulatory compliance: RoHS status reduces material-conformance risks in production and procurement.
• Backed by family design resources: Part of the LatticeECP2 family, which is supported by family-level documentation and tooling referenced in the LatticeECP2 data sheet.
