LFEC3E-5F256C

The LFEC3E-5F256C is a commercial-grade field programmable gate array (FPGA) from Lattice Semiconductor Corporation supplied in a 256-ball fpBGA package (17 × 17 mm). It integrates approximately 3,100 logic elements and 56,320 bits of on-chip RAM, with 160 user I/Os, making it suitable for mid-density embedded and system integration tasks where compact packaging and moderate logic/memory resources are required.

Designed for surface-mount assembly and RoHS-compliant production, this device operates from a 1.14 V to 1.26 V core supply and across a commercial temperature range of 0 °C to 85 °C, offering a balance of power efficiency and functionality for a range of commercial electronic designs.

Key Features

• Logic Capacity — Approximately 3,100 logic elements to implement combinational and sequential logic for control, glue logic, and mid-complexity functions.
• Embedded Memory — Total on-chip RAM of 56,320 bits (approximately 55 Kbits) for LUT-based storage, buffering, and small data structures.
• I/O Count — 160 user I/Os on a single device to support multiple external interfaces and mixed-signal front-ends when paired with appropriate I/O standards.
• Package and Mounting — 256-ball fpBGA (256-FPBGA, 17 × 17 mm) in a surface-mount form factor for compact board layouts and high-density routing.
• Power — Core voltage range of 1.14 V to 1.26 V to match low-voltage system domains and power management strategies.
• Operating Range — Commercial operating temperature from 0 °C to 85 °C suitable for consumer and general commercial applications.
• Regulatory — RoHS compliant for environmental and manufacturing compatibility.

Typical Applications

• Embedded Control and Glue Logic — Implement control state machines, interface bridging, and custom peripheral logic where a compact FPGA with moderate logic density is required.
• Communication Interfaces — Support protocol translation and I/O aggregation using the device’s 160 I/Os for medium-density communication endpoints and board-level connectivity.
• Signal Conditioning and Small DSP Tasks — Use on-chip RAM and logic elements for buffering, formatting, and basic signal processing tasks in commercial instrumentation or consumer devices.
• Prototyping and System Integration — Compact BGA package and surface-mount compatibility make this device suitable for integration into prototype and production PCBs where board area and I/O density matter.

Unique Advantages

• Balanced Logic and Memory — ~3,100 logic elements paired with 56,320 bits of RAM provide a mid-density resource mix for control, interfacing, and modest data buffering without requiring a larger device.
• High I/O Count in a Compact Package — 160 I/Os in a 17 × 17 mm 256-FPBGA enable extensive external connectivity while keeping board footprint small.
• Low-Voltage Operation — 1.14 V to 1.26 V core supply supports modern low-voltage system domains and helps reduce overall power consumption.
• Surface-Mount, RoHS-Compliant — Designed for standard surface-mount assembly and compliant with RoHS requirements for streamlined manufacturing and regulatory compatibility.
• Commercial Temperature Rating — 0 °C to 85 °C operating range aligns with consumer and commercial product requirements.
