LFE5U-45F-6MG285C

The LFE5U-45F-6MG285C is an ECP5 family FPGA device from Lattice Semiconductor, delivering a mid-density programmable logic resource set in a 285‑LFBGA package. It combines on‑chip embedded memory and a broad set of family-level architecture features described in the ECP5 data sheet.

This device is aimed at applications that require a balance of logic capacity, embedded RAM, flexible I/O and high‑integration in a surface‑mount 285‑CSFBGA (10×10) package while operating within a commercial temperature range.

Key Features

• Core Logic — Approximately 44,000 logic elements and roughly 11,000 logic blocks provide the programmable fabric for custom logic and control functions.
• Embedded Memory — Approximately 1.99 Mbits of on‑chip RAM for buffering, FIFOs, and distributed storage needs.
• I/O Capability — 118 user I/Os support a variety of external interfaces and board-level connectivity.
• Package & Mounting — 285‑LFBGA (CSPBGA) package, supplier device package listed as 285‑CSFBGA (10×10), designed for surface‑mount PCB assembly.
• Power — Core voltage supply range of 1.045 V to 1.155 V for the device core domain.
• Temperature & Grade — Commercial grade device rated for 0°C to 85°C operation.
• Family Architecture Features — ECP5 family data sheet documents integrated features such as programmable I/O cells, clocking (PLLs and clock distribution), DDR memory support, sysDSP slice functionality, SERDES and physical coding sublayer blocks, an on‑chip oscillator, and device configuration options.
• Compliance — RoHS compliant.

Unique Advantages

• Balanced logic and memory — Combines ~44k logic elements with approximately 1.99 Mbits of embedded RAM to support mid-density logic designs with substantial on‑chip buffering.
• Rich I/O and interface support — 118 I/Os plus family-level SERDES, programmable I/O cells and DDR support (per ECP5 family data sheet) enable flexible board‑level connectivity and external memory interfaces.
• Compact, surface‑mount package — 285‑LFBGA (285‑CSFBGA 10×10) provides a high‑density package option for space‑constrained PCBs.
• Deterministic core power window — A narrow core voltage range (1.045 V–1.155 V) aids in predictable power design for the device core domain.
• Family‑level system features — On‑chip PLLs, clock distribution, sysDSP slice capabilities and configuration options described in the ECP5 data sheet simplify implementation of timing, DSP and configuration functions.
• RoHS compliant and commercial grade — Designed for commercial temperature operation and RoHS‑compliant manufacturing environments.
