LFE5U-12F-7MG285C

The LFE5U-12F-7MG285C is an ECP5 family FPGA offered by Lattice Semiconductor, delivering a mid-range programmable fabric for embedded control, connectivity and logic-acceleration tasks. The device provides approximately 12,000 logic elements, roughly 0.59 Mbits of on-chip RAM, and 118 general-purpose I/O in a compact 285-LFBGA surface-mount package.

This commercial-grade FPGA is built for applications that require flexible I/O, on-chip memory and a range of on-die system blocks documented in the ECP5 family data sheet (PLL/clocking, programmable I/O, SERDES, memory and DSP resources), with a specified core voltage range of 1.045 V to 1.155 V and an operating temperature range of 0 °C to 85 °C.

Key Features

• Embedded Memory — Approximately 589,824 bits (~0.59 Mbits) of on-chip RAM for local buffering, FIFOs and small data stores.
• I/O and Package — 118 I/O pins in a 285-LFBGA (285-CSFBGA, 10×10) surface-mount package for compact board designs and flexible interfacing.
• Clocking and Timing — Family-level documentation includes sysCLOCK PLL and clock distribution network features to support multiple clock domains and timing architectures.
• High-speed Interfaces — ECP5 family references SERDES and PCS blocks and DDR memory support, enabling implementation of serial links and external memory interfaces.
• DSP and Memory Subsystems — Datasheet sections describe sysDSP slices and sysMEM blocks for arithmetic acceleration and flexible memory configurations.
• Device Configuration & Reliability — ECP5 family documentation includes device configuration options, on-chip oscillator, enhanced configuration features and Single Event Upset (SEU) support; boundary-scan (IEEE 1149.1) is also supported.
• Power and Operating Range — Core supply range specified from 1.045 V to 1.155 V; commercial operating temperature range 0 °C to 85 °C. Mounting type: surface mount.
• Regulatory — RoHS compliant.

Typical Applications

• Connectivity and Networking — Implement protocol bridging, SERDES-based links and custom PHY functions where on-chip serial transceivers and flexible I/O are required.
• Memory Interface Control — Build DDR interface logic and memory controllers using the device’s documented DDR support, DQS handling and sysMEM features.
• Embedded DSP and Signal Processing — Offload arithmetic-heavy tasks to the device’s sysDSP slices and local RAM for real-time processing and pre/post-processing pipelines.
• Embedded Control and Glue Logic — Replace CPLD/ASIC glue logic with a reprogrammable solution providing ample I/O and on-chip RAM for state machines, protocol handling and peripheral aggregation.

Unique Advantages

• Mid-range logic density with compact footprint: Approximately 12,000 logic elements in a 285-LFBGA package enables substantial functionality in a space-efficient surface-mount form factor.
• On-chip RAM for system efficiency: Nearly 0.59 Mbits of embedded memory reduces dependence on external RAM for buffering and small data stores, simplifying board-level design.
• Extensive I/O capability: 118 I/O pins provide flexible interfacing options for parallel buses, control signals and peripheral connectivity without immediate need for external expanders.
• Built-in system blocks: Family-level features such as PLLs, clock distribution, DDR support, SERDES, sysDSP and configuration options enable integrated subsystem designs with fewer external components.
• Commercial-grade readiness: Specified for 0 °C to 85 °C operation and RoHS compliance, suitable for mainstream embedded and industrial-adjacent applications within that temperature range.
• Surface-mount 285-CSFBGA packaging: Standardized 10×10 package option for automated assembly and consistent thermal/mechanical behavior on modern PCBs.
