LFE5U-45F-6BG256I

The LFE5U-45F-6BG256I is a Field Programmable Gate Array (FPGA) member of the Lattice ECP5 family, supplied in a 256-pin LFBGA package. It delivers reconfigurable logic capacity and on-chip memory targeted at industrial embedded designs that require a balance of logic density, I/O count and low-voltage core operation.

Built to support the ECP5 family architecture, this device is suitable for applications that need flexible I/O, substantial embedded memory, and configurable logic in a compact surface-mount package with industrial temperature range.

Key Features

• Logic Capacity  Approximately 44,000 logic elements and about 11,000 configurable logic blocks (CLBs) to implement complex custom logic and state machines.
• Embedded Memory  Approximately 1.99 Mbits of on-chip RAM for FIFOs, buffering and local storage to support data-paths and control structures.
• I/O  197 user I/Os to connect peripherals, sensors, memory interfaces and board-level devices without external multiplexing.
• Package  256-LFBGA (supplier package listed as 256-CABGA, 14×14) in a surface-mount form factor for compact board layouts.
• Power  Low-voltage core operation with recommended supply range of 1.045 V to 1.155 V to support modern low-power designs.
• Thermal & Grade  Industrial-grade device rated for operation from -40 °C to 100 °C for deployment in temperature-variable environments.
• Environmental Compliance  RoHS-compliant for regulatory compatibility in standard manufacturing flows.
• ECP5 Family Capabilities  Implements the ECP5 family architecture and feature set as described in the ECP5 datasheet, including routing, clocking, memory and SERDES-related blocks for a broad set of digital system designs.

Typical Applications

• Industrial Control  Implements control logic, deterministic sequencing, and I/O aggregation in factory automation and machine control systems where industrial temperature rating is required.
• Embedded Systems  Provides reconfigurable logic and on-chip RAM for custom protocol handling, peripheral bridging, and application-specific accelerators in embedded products.
• Communications & Interfaces  Serves as a protocol bridge, I/O expander or interface controller leveraging the device’s I/O count and ECP5 family interface capabilities.
• Prototyping and Development  Offers a compact reprogrammable platform for validating logic, timing and interfacing before production integration.

Unique Advantages

• Balanced Logic and Memory:  44,000 logic elements combined with ~1.99 Mbits of embedded RAM supports both control-oriented and data-path designs without excessive external memory.
• High I/O Density:  197 user I/Os reduce the need for external multiplexers or I/O expanders, simplifying PCB design and lowering BOM.
• Industrial Temperature Range:  Rated from -40 °C to 100 °C for deployment in temperature-challenging environments common to industrial applications.
• Low-Voltage Core:  1.045 V to 1.155 V supply requirement aligns with low-power system rails and modern power management strategies.
• Compact Surface-Mount Package:  256-LFBGA (14×14) package enables space-efficient board layouts for constrained form-factor designs.
• RoHS-Compliant:  Meets environmental compliance expectations for modern electronics manufacturing.
