LFE5UM5G-85F-8MG285C

The LFE5UM5G-85F-8MG285C is an ECP5-5G family field-programmable gate array from Lattice Semiconductor, supplied in a 285-CSFBGA (10×10) surface-mount package and provided in tray packaging. This commercial-grade FPGA integrates 84,000 logic elements and approximately 3.83 Mbits of on-chip RAM with 118 user I/Os, making it suitable for compact, performance-sensitive embedded designs.

Device and family documentation indicate on-chip features such as programmable I/O, SERDES and physical coding sublayer blocks, DSP-oriented resources, flexible clocking (including PLLs and clock distribution), and DDR memory support—enabling a range of interface, processing and memory-accelerated applications within the device’s specified operating conditions.

Key Features

• Logic Capacity  84,000 logic elements provide substantial programmable logic resources for combinational and sequential designs.
• Embedded Memory  Approximately 3.83 Mbits of total on-chip RAM for buffering, FIFO, and local storage requirements.
• I/O and Packaging  118 user I/Os in a compact 285-CSFBGA (10×10) package; surface-mount mounting and tray packaging support standard assembly flows.
• Clocking and Timing  Family-level clocking features include PLLs and a distributed clock network for system timing and synchronization (see family datasheet for detailed clock architecture).
• SERDES and Interface Support  ECP5/ECP5-5G family documentation lists SERDES blocks and physical coding sublayer capabilities for high-speed serial interfaces and flexible client interfacing.
• DSP and Memory Subsystems  Family resources include DSP-oriented slices and sysMEM blocks documented for efficient arithmetic and memory operations.
• Power and Supply  Defined core voltage specified at 1.045 V in the product data.
• Operating Range  Commercial operating temperature range: 0 °C to 85 °C, and commercial device grade classification.

Typical Applications

• High-speed interface bridging  Use the device’s SERDES and programmable I/O to implement protocol converters and serial links between subsystems.
• Embedded signal processing  Leverage DSP-oriented slices and on-chip RAM for tasks such as filtering, aggregation, and real-time data manipulation.
• DDR and memory controller support  Implement local memory buffering and DDR interface logic using the device’s documented DDR and memory features.
• Compact system controllers  Integrated logic density and a small BGA package enable space-constrained control and interface modules for embedded systems.

Unique Advantages

• High logic density: 84,000 logic elements deliver a balance of capacity for medium-to-complex designs without large-package overhead.
• Significant on-chip RAM: Approximately 3.83 Mbits of embedded memory reduces dependence on external RAM for many buffering and storage tasks.
• Flexible I/O in a compact package: 118 I/Os in a 285-CSFBGA (10×10) enable rich connectivity while minimizing PCB footprint.
• Family-level serial and DSP features: Documented SERDES, DSP slices, and PLL/clocking blocks provide building blocks for high-speed and compute-optimized designs.
• Defined supply and thermal envelope: Core voltage specified at 1.045 V and commercial temperature range (0 °C to 85 °C) simplify power and thermal planning for typical embedded applications.
