• Embedded Memory  Approximately 1.99 Mbits of on-chip RAM to support buffering, FIFOs, and local data storage.
• High I/O Count  245 user I/O pins enable rich connectivity for parallel buses, memory interfaces, and peripheral signals.
• Package & Mounting  554-FBGA (23×23) package, surface-mount mounting type for compact board-level integration.
• Power  Core supply range specified between 1.045 V and 1.155 V to match system power rails and enable predictable power design.
• Commercial Temperature  Rated for operation from 0 °C to 85 °C for commercial-grade deployments.
• Family-Level Architecture  ECP5 family features documented in the datasheet include flexible routing, clocking structure with sysCLOCK PLLs, DDR memory support, sysDSP slices, SERDES and PCS subsystems, programmable I/O cells, and device configuration options.
• RoHS Compliant  Meets RoHS environmental compliance for lead-free assembly and regulatory alignment.

Typical Applications

• Interface Bridging and Protocol Conversion  Use the high I/O count and SERDES/PCS-capable architecture to implement protocol translation and high-speed serial interfaces.
• Embedded and Commercial Systems  Integrate custom control logic, peripheral management, and timing-critical functions within compact commercial products.
• DDR Memory Controllers and Buffering  Leverage on-chip RAM and DDR-oriented features for buffering and memory interface logic.
• Signal Processing and Acceleration  Deploy sysDSP slices and programmable fabric for fixed-point signal-processing tasks and application-specific datapaths.

Unique Advantages

• High Logic Density:  44,000 logic elements provide substantial programmable capacity for complex finite-state machines, custom accelerators, and glue logic without external ASICs.
• Substantial On-Chip Memory:  Approximately 1.99 Mbits of embedded RAM reduces external memory dependence for many control and buffering needs.
• Extensive I/O:  245 I/Os enable broad system interfacing and flexible pin assignment for mixed-signal and digital peripherals.
• Integrated Family Features:  ECP5 family capabilities such as PLLs, flexible clock distribution, DDR support, SERDES, and sysDSP slices allow designers to consolidate multiple functions into a single FPGA.
• Compact Package:  554-FBGA (23×23) delivers a dense board footprint for space-constrained commercial products.
• Regulatory and Supply Parameters:  Commercial temperature rating (0 °C to 85 °C), defined core supply range (1.045 V–1.155 V), and RoHS compliance support predictable integration and environmental compliance.
