LFXP6C-4F256C

The LFXP6C-4F256C is a member of the LatticeXP family of non-volatile FPGAs, providing a mid-density reconfigurable logic solution with instant-on capability and in-field reconfiguration. It combines approximately 6,000 logic elements, about 73,728 bits of on-chip RAM and a 188-pin I/O count in a compact 256-ball FPBGA (17 × 17 mm) package.

Designed for commercial-temperature embedded applications, this device targets use cases that require flexible I/O, moderate embedded memory, and fast start-up or field updates while operating from a wide supply range of 1.71 V to 3.465 V.

Key Features

• Core logic: Approximately 6,000 logic elements organized across 720 PFU/PFF logic blocks, delivering mid-range programmable capacity for control, glue-logic and peripheral offload tasks.
• Embedded memory: Approximately 73,728 bits of on-chip RAM (embedded block and distributed memory) to support FIFOs, small buffers and data-path storage without immediate external SRAM.
• I/O flexibility: 188 user I/Os in a 256-ball FPBGA package (17 × 17 mm) for dense signal routing and perimeter I/O requirements.
• Non-volatile, instant-on architecture: LatticeXP family non-volatile configuration enables fast power-up without external configuration memory and supports in-field reconfiguration.
• Clocking and timing: Device-level PLL support consistent with the LatticeXP family (LFXP6 devices include 2 PLLs) for clock multiply/divide and phase adjustments.
• Power and voltage: Operates across a supply range of 1.71 V to 3.465 V and supports sleep-mode operation to dramatically reduce static current.
• Package and mounting: Surface-mount 256-FPBGA (17 × 17 mm) package providing a compact footprint with high I/O density.
• Commercial operating range: Specified for 0 °C to 85 °C operation, suitable for commercial-grade embedded products.
• Tool and IP ecosystem: Supported by the Lattice ispLEVER design tools and available ispLeverCORE IP modules for rapid implementation (family-level support).

Typical Applications

• Embedded control systems: Offload peripheral logic, implement custom control state machines or integrate multiple serial interfaces in compact embedded products.
• Interface bridging and protocol adaptation: Translate or aggregate signals between subsystems using the device’s flexible I/O and on-chip memory for buffering.
• Communications and data buffering: Implement medium-speed data-paths, FIFOs and protocol logic leveraging embedded RAM and PLL-based clocking.
• Consumer and commercial electronics: Add reconfigurable logic for custom I/O handling, display controllers or user-interface functions in products within a commercial temperature range.

Unique Advantages

• Instant-on, non-volatile configuration: Eliminates the need for external configuration memory and allows immediate device availability at power-up.
• Compact, high-density I/O package: 188 I/Os in a 256-FPBGA (17 × 17 mm) delivers substantial signal count in a small board area, reducing PCB complexity.
• Balanced logic and memory resources: Around 6,000 logic elements with approximately 73,728 bits of on-chip RAM supports mixed control and buffering needs without large external memory.
• Flexible voltage operation: Wide supply range (1.71 V to 3.465 V) enables designs that span multiple I/O voltage domains.
• Low-power sleep mode: Family-level sleep capability reduces static current for energy-sensitive commercial applications.
• Design ecosystem: Support from ispLEVER tools and pre-designed IP modules streamlines development and shortens time to prototype.
