LFE5UM-85F-6BG554C

The LFE5UM-85F-6BG554C is a commercial-grade FPGA IC from Lattice Semiconductor’s ECP5 family. It delivers mid-range programmable logic capacity with approximately 84,000 logic elements, about 3.8 Mbits of embedded memory, and a high I/O count for flexible board-level integration.

Designed for compact surface-mount assemblies, this device targets commercial designs that require substantial programmable logic, on-chip RAM, and extensive I/O while operating within a 1.045 V to 1.155 V core supply range and a 0 °C to 85 °C operating window.

Key Features

• Logic Capacity  Approximately 84,000 logic elements suitable for medium-complexity programmable logic implementations.
• Embedded Memory  Approximately 3.8 Mbits of on-chip RAM to support buffering, lookup tables, and state storage without external memory for many applications.
• High I/O Count  259 programmable I/Os provide broad interfacing options for peripherals, parallel buses, and multiple I/O standards described in the family datasheet.
• Package and Mounting  Available in a 554-FBGA (554-CABGA, 23 × 23 mm) package optimized for surface-mount PCB assembly, enabling dense board layouts.
• Power  Core supply voltage range of 1.045 V to 1.155 V to match system power rails and enable predictable power budgeting.
• Temperature and Grade  Commercial operating range of 0 °C to 85 °C; device is specified as Commercial grade.
• Standards and Compliance  RoHS compliant for regulatory compatibility in commercial electronic products.
• Family-Level Architecture (ECP5)  The ECP5 family datasheet documents architecture elements including clocking (sysCLOCK PLL), programmable I/O cells, DDR memory support, sysDSP slices, SERDES and physical coding sublayer, device configuration options (including on-chip oscillator), and reliability features such as SEU support.

Typical Applications

• Protocol Bridging and Glue Logic  Use the device’s logic density and abundant I/Os to implement custom protocol conversion and board-level glue logic between subsystems.
• Embedded Control and Signal Processing  Leverage on-chip memory and the family’s sysDSP documentation to perform buffering, control-state machines, and moderate signal-processing tasks.
• High‑I/O Peripheral Interfaces  The 259 I/Os make this FPGA suitable for dense peripheral interfaces, display controllers, or sensor aggregation where multiple signals must be handled concurrently.
• Communication Endpoints  Family-level SERDES and DDR support described in the datasheet enable use in communication endpoints requiring serial lanes or external memory interfaces.

Unique Advantages

• Highly integrated logic and memory: The combination of ~84,000 logic elements and roughly 3.8 Mbits of embedded RAM reduces dependence on external components for many designs.
• Broad I/O flexibility: With 259 I/Os and programmable I/O cell capability (per family documentation), the device supports complex board-level interfacing without major PCB redesign.
• Compact, manufacturable package: The 554-FBGA (23 × 23 mm) package provides a space-efficient footprint suitable for surface-mount assembly on dense boards.
• Controlled core power envelope: A defined core voltage range (1.045 V–1.155 V) helps with predictable power-supply design and system integration.
• Commercial operating range: Specified for 0 °C to 85 °C operation, matching many mainstream electronics applications.
• Regulatory readiness: RoHS compliance supports environmental regulatory needs for commercial products.
