LFE5U-85F-7BG756C

The LFE5U-85F-7BG756C is an ECP5 family FPGA from Lattice Semiconductor designed for programmable-logic integration in compact, surface-mount systems. It offers a combination of substantial logic capacity, multi-megabit embedded memory, and a high I/O count in a 756-pin FBGA package suitable for commercial temperature applications.

Key Features

• Logic Capacity  84,000 logic elements and 21,000 CLBs provide the programmable fabric to implement complex combinational and sequential logic.
• Embedded Memory  Approximately 3.83 Mbits of on-chip RAM for buffering, FIFOs, and small on-chip data stores.
• I/O Resources  365 user I/O pins to support diverse parallel interfaces and board-level connectivity.
• Package & Mounting  756-FBGA (756-CABGA, 27 × 27 mm) package, surface-mount for compact PCB designs.
• Power  Core supply range from 1.045 V to 1.155 V, enabling designs that target low-voltage core domains.
• Operating Range & Grade  Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Standards & Compliance  RoHS-compliant manufacturing status for environmental compliance.
• ECP5 Family Architecture (from datasheet)  Family-level features documented in the ECP5 data sheet include programmable I/O cells, clocking structures, embedded DSP and memory blocks, DDR support, and SERDES/PCS elements for system-level design flexibility.

Unique Advantages

• High logic density: 84,000 logic elements enable integration of complex control, glue logic, and custom datapaths while reducing external components.
• Generous on-chip memory: Approximately 3.83 Mbits of embedded RAM supports buffering and local storage without immediate dependence on external memory.
• Large I/O complement: 365 I/Os accommodate multiple interfaces and high-pin-count connectors on a single device.
• Compact manufacturing footprint: 756-FBGA package with surface-mount mounting helps save board area in dense designs.
• Low-voltage core: Narrow core supply window (1.045–1.155 V) supports power-optimized system architectures.
• Documented family capabilities: ECP5 family documentation details clocking, programmable I/O, memory, DSP slices, and SERDES support to aid system design and verification.
