LFE5U-85F-7MG285C

The LFE5U-85F-7MG285C is a Field Programmable Gate Array (FPGA) from the Lattice ECP5 family. It combines a substantial logic fabric with embedded RAM and a broad set of on-chip features described in the ECP5 family data sheet.

With 84,000 logic elements, approximately 3.83 Mbits of embedded memory, and 118 I/O pins in a 285-LFBGA (285-CSFBGA 10×10) package, this commercial-grade, surface-mount FPGA targets applications requiring mid-range logic density, flexible I/O and low-voltage operation (1.045 V–1.155 V).

Key Features

• Core Logic  About 21,000 logic blocks delivering 84,000 logic elements to implement custom digital logic and control functions.
• Embedded Memory  Approximately 3.83 Mbits of on-chip RAM for FIFOs, buffers, and local storage.
• I/O and Interfaces  118 programmable I/O pins with on-chip I/O features documented in the ECP5 family data sheet, supporting varied board-level interfacing and termination options.
• SERDES and Memory Support  Family-level support includes SERDES/PCS and DDR memory features described in the datasheet for use with high-speed serial links and external memory interfaces.
• Clocking and DSP  ECP5 family architecture includes sysCLOCK PLLs, clock distribution and sysDSP slices to support timing and signal processing needs (see family data sheet for details).
• Power and Voltage  Operates within a supply voltage range of 1.045 V to 1.155 V, enabling designs that target low-voltage domains.
• Package and Mounting  285-LFBGA (supplier package: 285-CSFBGA 10×10) in a surface-mount form factor for compact PCB layouts.
• Commercial Grade & Environmental  Grade: Commercial; operating temperature range 0 °C to 85 °C. RoHS compliant.

Typical Applications

• High-speed serial interfaces  Leverages the ECP5 family’s SERDES and PCS blocks for implementing serial link endpoints and protocol bridging.
• DDR memory interfaces  DDR support and DQS grouping capabilities (described in the datasheet) make the device suitable for designs that require external memory controllers and calibrated DQS handling.
• Embedded logic and DSP functions  Abundant logic elements and sysDSP resources support custom signal processing, protocol engines, and control logic implementations.
• Flexible board-level I/O  118 I/O pins with programmable I/O buffer features allow integration with sensors, peripherals and mixed-signal interfaces while supporting on-chip termination and hot-socketing behaviors described in the family documentation.

Unique Advantages

• Substantial logic capacity: 84,000 logic elements enable mid-range FPGA designs without moving to larger package footprints.
• On-chip RAM for system buffering: Approximately 3.83 Mbits of embedded memory reduces external memory dependence for many control and buffering tasks.
• Compact package: 285-LFBGA (285-CSFBGA 10×10) surface-mount package supports dense PCB integration while exposing 118 I/O for flexible connectivity.
• Low-voltage operation: Narrow supply range (1.045 V–1.155 V) suitable for designs targeting low-voltage power domains.
• Commercial temperature suitability: Rated for 0 °C to 85 °C for standard commercial environments.
• Standards-conscious supply chain: RoHS compliant to meet regulatory and manufacturing requirements.
