• Logic block count — 11,000 CLBs (as listed in product data) supporting combinatorial and registered functions across the device.
• Embedded memory — Total on-chip RAM of 1,990,656 bits (approximately 1.99 Mbits) for buffering, FIFOs, and local storage.
• I/O capacity — 245 programmable I/O pins in a 554-FBGA package for broad interface flexibility.
• High-speed interfaces and DSP — Family-level architecture includes SERDES, sysDSP slice, and programmable I/O cells as described in the ECP5 datasheet.
• Clocking and timing — Integrated clocking architecture with PLLs and distributed clock networks documented in the ECP5 family data sheet.
• Power and supply — Core voltage supply range of 1.045 V to 1.155 V to match supported operating conditions.
• Package and mounting — 554-CABGA (23×23) package in 554-FBGA format, surface-mount mounting type for board-level integration.
• Temperature and grade — Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Environmental — RoHS compliant.

Typical Applications

• High-speed interface bridging — Use SERDES and programmable I/O to implement protocol conversion and link aggregation in communications and networking modules.
• Memory controller and buffering — On-chip RAM and DDR support in the ECP5 family enable memory interface logic and data buffering tasks.
• Embedded control and I/O aggregation — Mid-density logic and abundant I/O make the device suitable for consolidating control, sensor interfaces, and peripheral management.

Unique Advantages

• Balanced logic and memory — Combines approximately 44,000 logic elements with about 1.99 Mbits of embedded RAM to support both control logic and local data storage.
• Generous I/O count — 245 I/Os in a compact 554-FBGA package provide broad interface options without a large board footprint.
• Compact surface-mount package — 554-CABGA (23×23) packaging enables integration into space-constrained assemblies.
• Family-level feature set — ECP5 family architecture described in the datasheet includes programmable I/O cells, sysDSP slices, SERDES blocks and PLL-based clocking for flexible system integration.
• Controlled supply range — Core supply specification (1.045 V to 1.155 V) supports predictable power design and sequencing per device recommendations.
• Regulatory compliance — RoHS compliance simplifies environmental and sourcing requirements.
