LFE5U-45F-7MG285C

The LFE5U-45F-7MG285C is an ECP5 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor, delivered in a 285-LFBGA (10×10) package. It provides reconfigurable logic, embedded memory, and flexible I/O in a commercial-grade device optimized for compact, low-voltage system designs.

Built on the ECP5 family architecture, the device supports programmable logic, on-chip memory and specialized fabric blocks described in the ECP5 data sheet, enabling implementation of custom digital functions, memory interfaces and I/O-rich subsystems.

Key Features

• Core Logic  Approximately 44,000 logic elements for implementing combinational and sequential logic functions.
• Embedded Memory  Approximately 1.99 Mbits of on-chip RAM to support buffering, FIFOs and local data storage.
• I/O Density  118 user I/O pins with programmable I/O cell architecture for flexible interfacing to external devices.
• Clocking and Timing  Integrated clocking resources and PLLs as described in the ECP5 family data sheet to support system and high-performance clock domains.
• DSP and Memory Subsystems  sysDSP and sysMEM blocks (documented in the ECP5 data sheet) provide dedicated resources for arithmetic and memory-intensive operations.
• SERDES and DDR Support  Architecture-level support for SERDES and DDR memory interfaces as outlined in the ECP5 family documentation, including DQS grouping and DLL-calibrated DQS control.
• Power and Supply  Core supply operating range from 1.045 V to 1.155 V for the device core.
• Package & Mounting  285-LFBGA (285-CSFBGA, 10×10) surface-mount package suitable for compact board designs.
• Operating Conditions  Commercial temperature range: 0 °C to 85 °C. RoHS compliant.

Typical Applications

• Memory Interface and Controller Implementation  Use the device’s documented DDR support and DQS calibration features to implement external memory controllers and buffering logic.
• High-speed I/O Bridging  Leverage the programmable I/O cells and SERDES-capable fabric for protocol bridging and I/O consolidation tasks.
• DSP and Data Processing  Employ the sysDSP slice resources and on-chip RAM for arithmetic acceleration, streaming datapaths and local buffering.
• Compact Embedded Systems  The 285-LFBGA package and surface-mount mounting type suit space-constrained boards requiring reprogrammable logic and flexible I/O.

Unique Advantages

• High Logic Density: Approximately 44,000 logic elements enable substantial integration of custom logic without external PLDs.
• On-chip Memory Capacity: Nearly 2 Mbits of embedded RAM reduces dependence on external memory for many buffering and state-storage needs.
• Flexible I/O Architecture: 118 programmable I/Os and documented programmable I/O cell features enable straightforward interfacing to a wide range of peripherals.
• Package Efficiency: The 285-LFBGA (10×10) package provides a compact footprint for designs where board area is constrained.
• Low-voltage Core Operation: A defined core supply range of 1.045 V–1.155 V supports low-voltage system designs.
• Commercial Grade with RoHS Compliance: Suitable for a broad set of commercial applications while meeting RoHS environmental requirements.
