Key Features
- Logic Capacity Approximately 44,000 logic elements organized as 11,000 CLBs, providing room for complex FPGA designs and custom logic functions.
- Embedded Memory Approximately 1.99 Mbits of on-chip RAM to support buffering, FIFOs, and on-chip data storage.
- I/O Resources 197 device I/Os for flexible interfacing to peripherals, sensors, and external memory.
- Power Supply Specified operating supply range of 1.045 V to 1.155 V for core power planning and regulator selection.
- Industrial Temperature Range Qualified for operation from −40 °C to 100 °C to meet industrial environmental requirements.
- Package & Mounting 256-LFBGA surface-mount package; supplier device package listed as 256-CABGA (14×14) to support high-density board layouts.
- Series-Level Architecture ECP5 family features described in the datasheet include DDR memory support, SERDES blocks, programmable I/O cells, on-chip PLLs and clocking structures, and dedicated DSP/memory resources to support diverse system functions.
- Regulatory RoHS compliant to support environmental and supply-chain requirements.
Typical Applications
- Industrial Control Implement custom control logic, sensor aggregation, and I/O bridging in factory automation and process control equipment.
- Communications & Connectivity Use available SERDES and I/O resources for protocol bridging, datapath processing, and interface adaptation in communication systems.
- Embedded Signal Processing Leverage on-chip memory and DSP-oriented slices (as described in the ECP5 family datasheet) for real-time data buffering and arithmetic processing.
- Custom Logic Integration Consolidate discrete logic, glue functions, and peripheral interfaces into a single reconfigurable device to reduce BOM and board complexity.
Unique Advantages
- Balanced Logic and Memory Combines approximately 44,000 logic elements with nearly 2 Mbits of embedded RAM to handle mid-density logic and data buffering without external memory in many designs.
- High I/O Count 197 I/Os enable extensive peripheral connectivity and flexible pin assignment for mixed-signal and mixed-function boards.
- Industrial Qualification Rated for −40 °C to 100 °C operation, making it suitable for many industrial environments that demand extended temperature tolerance.
- Compact, Surface-Mount Package 256-ball LFBGA footprint supports high-density PCB layouts while maintaining robust mounting for production assembly.
- Design Flexibility from ECP5 Architecture Family-level features such as programmable I/O, DDR support, SERDES, and on-chip clocking give designers system-level options without relying solely on external components.
- RoHS Compliance Supports environmental compliance requirements for commercial and industrial supply chains.
