LFE3-17EA-8LFTN256C

The LFE3-17EA-8LFTN256C is an ECP3 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor. It provides a mid-density programmable logic fabric with 17,000 logic elements and on-chip embedded memory for customizable digital logic implementations.

Designed for reconfigurable designs that require moderate embedded memory, a defined number of I/Os, and a compact Ball Grid Array package, this device is suitable for commercial-grade applications operating within standard temperature and voltage ranges.

Key Features

• Core Capacity  17,000 logic elements supporting configurable digital logic implementations and adaptable hardware functions.
• Logic Array Blocks  2,125 logic array blocks (LABs) to structure and map logic resources efficiently.
• Embedded Memory  Approximately 0.72 Mbits of on-chip RAM (716,800 total RAM bits) for buffering, processing, and state storage within user designs.
• I/O Resources  Up to 133 general-purpose I/Os to interface with peripherals, sensors, and other system components.
• Power  Low-voltage core operation with a supply range of 1.14 V to 1.26 V.
• Package & Mounting  256-BGA package in a 256-FTBGA (17 × 17) footprint, intended for surface-mount PCB assembly.
• Temperature & Grade  Commercial grade operation from 0°C to 85°C.
• Compliance  RoHS-compliant for environmental regulation conformance.

Typical Applications

• Custom digital logic  Implement glue logic, protocol handling, or application-specific accelerators where reprogrammability and 17,000 logic elements provide design flexibility.
• Interface bridging  Use the 133 I/Os to connect and translate between multiple digital interfaces or to aggregate sensor and peripheral signals.
• Embedded control and state machines  Leverage the on-chip RAM and logic resources for deterministic control, sequencing, and real-time finite-state implementations.
• Prototyping and development  Deploy as a reconfigurable platform for hardware prototyping that requires a mid-density FPGA with a compact BGA package.

Unique Advantages

• Significant mid-range logic capacity: 17,000 logic elements enable complex combinational and sequential logic without moving to larger, higher-cost devices.
• Structured logic resources: 2,125 LABs help organize designs and map logic efficiently across the fabric.
• On-chip memory for local buffering: Approximately 0.72 Mbits of embedded RAM reduces dependence on external memory for many control and data-path tasks.
• Generous I/O count: 133 I/Os support multiple peripherals and interfaces directly, simplifying board-level connectivity.
• Compact BGA footprint: 256-FTBGA (17×17) package provides a dense, surface-mount solution for space-constrained PCBs.
• Low-voltage core operation: 1.14–1.26 V supply range supports modern low-voltage system designs.
