Key Features

• Core Logic  44,000 logic elements provide flexible programmable logic capacity for custom digital designs.
• Embedded Memory  Approximately 2.0 Mbits (1,990,656 bits) of on-chip RAM to support buffering, FIFOs, and embedded data storage.
• I/O Density  197 user I/O pins support rich parallel and serial interfacing on a single device.
• Packaging & Mounting  256-LFBGA package (Supplier device package: 256-CABGA (14x14)) in a surface-mount form factor for compact board layouts.
• Power Supply  Supported core supply range of 1.045 V to 1.155 V for device operation.
• Temperature & Grade  Commercial-grade device rated for operation from 0 °C to 85 °C.
• Standards & Compliance  RoHS compliant.
• ECP5 Family Architecture  Based on the ECP5 family architecture (datasheet sections include clocking, memory, DSP, SERDES, and programmable I/O), enabling features such as DDR memory support, SERDES, sysDSP, and flexible I/O management.

Typical Applications

• High-speed serial interfaces  Leverage the ECP5 family SERDES and physical coding support to implement serial link endpoints and protocol bridging.
• Memory interface and buffering  Use on-chip RAM and documented DDR memory support for data buffering, memory controllers, and bus-width matching.
• Embedded DSP and signal processing  Implement fixed-function or custom DSP pipelines using the sysDSP slice architecture described in the family datasheet.
• Custom control and glue logic  Utilize 44,000 logic elements and 197 I/O for glue logic, protocol conversion, and board-level control functions.

Unique Advantages

• Balanced logic and memory ratio: 44,000 logic elements paired with approximately 2.0 Mbits of embedded RAM allow datapath-heavy designs with local buffering on a single device.
• High I/O count: 197 general-purpose I/O pins simplify board-level integration and reduce the need for external multiplexers or expanders.
• Compact surface-mount package: 256-LFBGA (supplier 256-CABGA (14x14)) provides a high-pin-count solution in a compact footprint for space-constrained designs.
• Family-level signal and memory features: ECP5 family architecture includes SERDES, DDR support, sysDSP, and flexible clocking—enabling a range of interface and processing implementations.
• Commercial temperature rating: Rated for 0 °C to 85 °C operation to match typical commercial embedded and electronics applications.
• Regulatory compliance: RoHS compliant for global manufacturing compatibility.
