LFE5U-12F-7BG381C

The LFE5U-12F-7BG381C is a member of the ECP5 family of FPGAs from Lattice Semiconductor, providing mid-range programmable logic in a compact 381-ball FBGA package. It combines configurable logic, embedded memory, and flexible I/O in a surface-mount 17 × 17 CABGA footprint for space-constrained designs.

This device targets designs that require up to 12,000 logic elements, substantial on-chip RAM, and broad I/O capability—delivering a balance of integration, I/O density, and system-level features described in the ECP5 family data sheet.

Key Features

• Logic Capacity — 12,000 logic elements (cells) suitable for mid-density programmable logic implementations and custom digital functions.
• Embedded Memory — Approximately 0.59 Mbits (589,824 bits) of on-chip RAM for buffering, lookup tables, and small memory structures.
• I/O Density — 197 user I/O pins to support extensive peripheral interfacing and board-level connectivity in a single device.
• Power and Voltage — Core voltage supply range of 1.045 V to 1.155 V, supporting low-voltage system integration.
• Packaging and Mounting — 381-FBGA (381-CABGA 17×17) surface-mount package for compact board layouts and reliable soldered mounting.
• Operating Range — Commercial temperature grade with an operating range of 0 °C to 85 °C.
• ECP5 Family Architecture — Family-level features documented in the datasheet include programmable logic slices, sysMEM memory blocks, sysDSP slices, flexible clocking with sysCLOCK PLL, DDR memory support, SERDES and PCS blocks, programmable I/O cells, on-chip oscillator, and IEEE 1149.1-compliant boundary scan testability.
• Standards and Compliance — RoHS compliant for lead-free assembly and regulatory alignment.

Typical Applications

• High-speed serial interfaces — Use the ECP5 family’s SERDES and PCS blocks to implement serial link endpoints and protocol bridging.
• Memory interface and buffering — DDR memory support and embedded sysMEM blocks provide resources for memory controllers, buffering, and data staging logic.
• Embedded signal processing — sysDSP slice capability combined with on-chip RAM enables compact DSP and real-time processing pipelines.
• I/O expansion and glue logic — 197 I/Os and programmable I/O cells make the device suitable for consolidating board-level logic, protocol translation, and peripheral aggregation.
• Compact, space-constrained systems — 381-FBGA (17×17) surface-mount package fits dense PCB layouts where board area is limited.

Unique Advantages

• Mid-density integration: 12,000 logic elements deliver a balance between capacity and cost for a wide range of programmable logic tasks without overprovisioning.
• On-chip memory for system-level tasks: Approximately 0.59 Mbits of embedded RAM reduces external memory dependence for many buffering and LUT requirements.
• High I/O count: 197 I/Os enable extensive peripheral connectivity and simplify board-level routing by consolidating signals into a single device.
• System-level features from the ECP5 family: Documented support for PLL-based clocking, DDR interfaces, SERDES, programmable I/O, and boundary scan simplifies implementation of complex interfaces.
• Compact FBGA package: The 381-CABGA (17×17) package supports dense PCB designs while maintaining reliable surface-mount assembly.
• RoHS-compliant: Meets lead-free assembly requirements for modern electronics manufacturing processes.
