LFE2-70E-6FN900I

The LFE2-70E-6FN900I is an ECP2 Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation designed for industrial-grade programmable logic applications. It delivers a high logic capacity and on-chip embedded memory in a compact 900‑ball BGA package, suitable for space-constrained, performance-sensitive designs that require broad I/O and industrial temperature operation.

With 68,000 logic elements, approximately 1.06 Mbits of embedded memory and 583 I/Os, this device balances logic density, memory and I/O integration while operating from a 1.14 V to 1.26 V core supply and across an industrial temperature range.

Key Features

• Logic Capacity  Provides 68,000 logic elements to implement medium-to-large custom logic functions and datapaths.
• Embedded Memory  Approximately 1.06 Mbits of on-chip RAM to support buffering, FIFOs and on-chip data structures without external memory.
• High I/O Count  583 I/O pins enable extensive peripheral interfacing and parallel connectivity directly from the FPGA fabric.
• Power Supply  Core voltage support from 1.14 V to 1.26 V for predictable power and thermal planning in board designs.
• Package & Mounting  900‑BBGA (supplier device package: 900‑FPBGA, 31×31) in a surface-mount format for compact, high-density PCB layouts.
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C, supporting deployment in industrial environments.
• RoHS Compliant  Meets RoHS requirements for materials compliance.

Typical Applications

• Industrial Automation  Industrial-grade temperature rating and high logic density make this FPGA suitable for control, signal processing and custom logic tasks in factory and process automation systems.
• Embedded Systems  Large logic capacity and significant on-chip RAM support complex embedded processing, glue logic and protocol bridging without relying solely on external components.
• High-Density I/O Designs  With 583 I/Os, the device is well suited for applications requiring many sensor, actuator or parallel peripheral interfaces on a single FPGA.

Unique Advantages

• High Logic Integration: 68,000 logic elements reduce the need for multiple FPGAs or external glue logic, simplifying BOM and board complexity.
• Embedded Memory On-Chip: Approximately 1.06 Mbits of RAM enables internal buffering and data handling without immediate external memory, improving latency and reliability.
• Extensive I/O: 583 I/Os allow dense connectivity to peripherals, sensors and buses, consolidating system interfaces onto one device.
• Industrial Thermal Range: Operation from −40 °C to 100 °C supports deployment in demanding environments where extended temperature tolerance is required.
• Compact Package: 900‑BBGA (31×31) surface-mount package offers a small footprint for board area-constrained designs while maintaining high pin count.
• Regulatory Compliance: RoHS compliance aids in meeting material and environmental requirements for product manufacturing.
