LFE2-50SE-5FN672I

The LFE2-50SE-5FN672I is an ECP2 Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation. It combines a large logic fabric with substantial on-chip RAM and a high I/O count in a compact 672-BBGA package.

Engineered for industrial environments, this device supports a wide operating temperature range and low-voltage core operation, making it suitable for designs that require high integration, robust I/O capability, and embedded memory close to the logic.

Key Features

• Core & Logic  Approximately 48,000 logic elements provide a flexible fabric for implementing custom digital logic, state machines, and control functions.
• Embedded Memory  Approximately 0.396 Mbits of on-chip RAM (396,288 total RAM bits) for buffering, lookup tables, and state storage without external memory.
• I/O Capacity  Up to 500 I/O pins support extensive peripheral interfacing and multi-channel connectivity in complex systems.
• Power  Core supply voltage range of 1.14 V to 1.26 V for low-voltage operation.
• Package & Mounting  672-BBGA package (supplier device package: 672-FPBGA 27×27) in a surface-mount form factor for dense board-level integration.
• Temperature & Grade  Industrial grade device rated for operation from −40 °C to 100 °C, suitable for demanding environments.
• Regulatory  RoHS compliant.

Typical Applications

• Industrial Control Systems  Interfaces sensors and actuators and implements deterministic control logic while operating across an industrial temperature range.
• High-Density I/O Systems  Aggregates multiple peripherals and buses using the device's 500 I/O pins for complex connectivity and board-level consolidation.
• Embedded Memory-Dependent Logic  Uses approximately 0.396 Mbits of on-chip RAM for buffering, FIFOs, and small lookup tables to reduce external memory needs.
• Custom Logic and Protocol Bridging  Implements tailored state machines and interface translation in compact, surface-mount hardware designs.

Unique Advantages

• High logic capacity: Approximately 48,000 logic elements enable implementation of sizable custom hardware functions on a single device, reducing board count.
• Substantial I/O integration: Up to 500 I/O pins allow direct connection to many peripherals and interfaces, simplifying system routing and PCB layout.
• On-chip RAM for local buffering: Nearly 0.396 Mbits of embedded memory helps minimize external memory components and lowers system latency.
• Industrial temperature rating: −40 °C to 100 °C operation supports deployment in harsher environments common in industrial applications.
• Compact BGA footprint: 672-BBGA (27×27) surface-mount package balances high pin count with a small PCB area.
• Low-voltage core: 1.14 V to 1.26 V supply range supports modern low-power system architectures.
