LFEC15E-3FN484I

The LFEC15E-3FN484I is an industrial-grade EC FPGA from Lattice Semiconductor Corporation, delivered in a 484-ball BGA package (484-FPBGA, 23 × 23 mm) with surface-mount mounting. The device implements a mid-range LatticeECP/EC FPGA fabric that combines approximately 15,400 logic elements, around 0.36 Mbits of on-chip embedded memory, and a 352-pin I/O capacity to address designs that require substantial I/O, moderate logic density, and system-level integration.

With a 1.14 V to 1.26 V core supply window and an extended operating temperature range of −40 °C to 100 °C, this part is suited for industrial applications where stable power and thermal performance are required.

Key Features

• Core Logic  Approximately 15,400 logic elements provide mid-range logic density for control, glue-logic, and protocol implementation within the LatticeECP/EC family architecture.
• Embedded Memory  Approximately 358,400 bits (≈0.36 Mbits) of on-chip RAM to support frame buffers, FIFOs, and small data stores without external memory for many control and interface functions.
• I/O Capacity  352 user I/Os in a 484-ball FPBGA footprint enable broad external interfacing and parallel connectivity for peripherals, sensors, and high-pin-count buses.
• Power  Core supply specified from 1.14 V to 1.26 V for regulated-power system designs.
• Clocking and Timing  Family-level architecture includes multiple PLLs (4 PLLs indicated for the LFEC15 family) to support clock management, frequency synthesis, and phase alignment in system designs.
• System-Level Support  LatticeECP/EC family features include IEEE 1149.1 boundary scan and SPI boot flash interface, providing standard board-level test and configuration options.
• Package & Mounting  484-BBGA (supplier: 484-FPBGA, 23 × 23 mm) with surface-mount mounting for high-density PCB designs.
• Industrial Temperature Grade  Rated for operation from −40 °C to 100 °C, suitable for industrial-environment deployments.
• RoHS Compliant  Manufactured to meet RoHS requirements for restricted substances.

Typical Applications

• Industrial Control & Automation  Use the LFEC15E-3FN484I for logic-intensive control, sensor aggregation, and I/O-rich automation modules that require industrial temperature operation.
• Communications & Networking  High I/O count and integrated clocking resources make this device suitable for protocol bridging, interface adaptation, and mid-range packet processing tasks.
• Embedded System Glue Logic  Mid-range logic density and on-chip memory enable consolidation of glue logic, peripheral interfacing, and small buffering functions onto a single FPGA.

Unique Advantages

• Balanced Logic and I/O Density:  Approximately 15,400 logic elements paired with 352 I/Os provides a practical balance for designs that need both compute and connectivity without moving to larger device families.
• On-Chip Memory for Compact Designs:  Around 0.36 Mbits of embedded RAM reduces dependence on external SRAM for many control and buffering use cases, simplifying BOM and board layout.
• Industrial Temperature Range:  Guaranteed operation from −40 °C to 100 °C supports deployment in harsher environments than commercial-grade components.
• Standard System Interfaces:  Family-level support for IEEE 1149.1 boundary scan and SPI boot flash interface eases board bring-up, programming, and test integration.
• Design Ecosystem Support:  The LatticeECP/EC family is supported by Lattice design flows and IP modules, enabling quicker development cycles and reuse of proven IP where applicable.
