• Core Logic 84,000 logic elements provide capacity for substantial custom logic, finite-state machines, and glue-logic integration in a single device.
• Embedded Memory Approximately 3.83 Mbits of on-chip RAM to store buffers, FIFOs, and working data close to logic for reduced external memory dependence.
• I/O Capability 365 I/O pins support dense peripheral and bus connectivity for multi-interface designs and extensive sensor or actuator wiring.
• Power Supply Supported core voltage range from 1.045 V to 1.155 V, enabling precise power budgeting and predictable supply requirements.
• Package & Mounting 756-pin FBGA (supplier package 756-CABGA, 27×27) in a surface-mount form factor for compact PCB layouts and automated assembly.
• Industrial Temperature Range Rated for operation from −40 °C to 100 °C, meeting broad environmental conditions typical of industrial deployments.
• Standards & Family Architecture Based on the ECP5-5G family architecture with documented features such as programmable I/O, PLLs, memory blocks, DSP slices and SERDES capabilities as described in the family data sheet.
• RoHS Compliant Device is RoHS compliant for regulatory and manufacturing requirements.

Typical Applications

• High-density interface bridging Use the large I/O count and logic capacity to implement protocol conversion, bus bridging, and multi-interface aggregation in compact industrial systems.
• Embedded signal processing Combine logic and on-chip RAM to implement data pre-processing, filtering, and deterministic control functions without immediate reliance on external memory.
• Memory-interface and SERDES clients Family-level support for DDR interfaces and SERDES blocks (as documented in the ECP5-5G datasheet) makes the device suitable for designs requiring high-speed I/O links and DDR memory front-ends.
• Industrial control and automation Industrial temperature rating and robust I/O count enable motor control, sensor aggregation, and machine control tasks in factory and process environments.

Unique Advantages

• High on-chip integration: 84,000 logic elements and embedded RAM reduce the need for multiple external components, simplifying BOM and PCB area.
• Extensive I/O: 365 I/Os enable direct connection to many peripherals and interfaces, minimizing external multiplexing or bridge devices.
• Industrial-grade operation: Rated from −40 °C to 100 °C to support deployments in demanding environmental conditions.
• Compact, assembly-friendly package: 756-FBGA (27×27) surface-mount package balances pin count with a small PCB footprint for space-constrained designs.
• Predictable power envelope: Narrow core voltage window (1.045 V–1.155 V) aids supply design and power sequencing.
• Standards-backed architecture: Device is part of the ECP5-5G family with documented features including programmable I/O, PLLs, sysMEM and SERDES capabilities referenced in the family datasheet.
