• Power Supply  Specified core supply range from 1.045 V to 1.155 V for core power planning and regulator selection.
• Commercial Grade Operating Range  Rated for 0 °C to 85 °C operation and listed as commercial grade.
• Mounting and Compliance  Surface mount package; RoHS compliant.
• Family-Level Capabilities  ECP5 family documentation indicates support for features such as programmable I/O cells, DDR memory interfaces, SERDES/PCS blocks, and flexible clocking and routing architectures (see ECP5 family data sheet for family-level details).

Typical Applications

• Interface Bridging and Protocol Conversion  Use the device’s high I/O count and programmable fabric to implement custom bridging between parallel and serial interfaces or legacy and modern peripherals.
• Embedded Control and Glue Logic  Deploy as centralized logic for coordinating system peripherals, handling custom timing, and offloading deterministic control tasks from microcontrollers.
• Video and Image Preprocessing  Leverage on-chip logic and embedded memory to implement buffering, simple filtering, and data formatting for video pipelines at moderate complexity.
• Test, Measurement, and Prototyping  Suitable for development platforms and instrumentation where reprogrammable logic, abundant I/O, and on-chip memory accelerate system evaluation and iterations.

Unique Advantages

• Well-balanced resource mix: 44,000 logic elements combined with ~1.99 Mbits of RAM provides designers the flexibility to implement control, signal processing, and interface functions in a single device.
• High I/O density in a compact package: 245 I/O and a 23 × 23 mm 554-CABGA footprint enable rich system connectivity while conserving PCB area.
• Commercial-grade suitability: Specified operating range of 0 °C to 85 °C aligns with a wide range of commercial applications and environments.
• Low-voltage core operation: Narrow core supply window (1.045 V–1.155 V) supports modern low-voltage power architectures and careful power budgeting.
• RoHS compliant: Meets environmental compliance requirements for lead-free assembly processes and global procurement.
• Family-level architectural features: ECP5 family documentation describes integrated clocking, memory modes, programmable I/O, DDR memory support, and SERDES/PCS building blocks that enable common FPGA system functions.
