LFE2-50E-7FN484C

The LFE2-50E-7FN484C is a Lattice ECP2 family field programmable gate array (FPGA) in a 484-ball fpBGA package. It combines a high logic element count with substantial I/O and embedded memory to serve a range of commercial embedded and system-integration designs.

Designed for applications that require programmable logic, on-chip memory and flexible I/O, this device delivers integration and configurability while operating from a 1.14 V to 1.26 V supply and a commercial temperature range of 0 °C to 85 °C.

Key Features

• Core logic — 48,000 logic elements and 6,000 CLBs provide extensive LUT-based logic resources for implementing complex digital functions and control logic.
• Embedded memory — Approximately 0.40 Mbits of on-chip RAM (396,288 total bits) for data buffering, state storage and local scratch memory.
• sysDSP and arithmetic — ECP2-50 family allocation includes 18 sysDSP blocks with support for multiple multiplier widths (family-level capability), enabling high-performance multiply-accumulate operations in hardware.
• I/O capacity and flexibility — 339 user I/Os provided in the 484-ball fpBGA footprint; programmable I/O buffer features in the ECP2 family support a wide range of signaling standards for interface flexibility.
• Clocking resources — Family-level PLL/DLL resources (GPLLs, SPLLs and DLLs) enable clock multiplication, division and phase/delay adjustment for system timing requirements.
• Power and thermal — Low-voltage core operation (1.14 V to 1.26 V) and surface-mount 484-BBGA package (484-FPBGA, 23 × 23 mm) suited to compact board layouts; commercial grade operation from 0 °C to 85 °C.
• Compliance — RoHS compliant construction for environmental compliance.

Typical Applications

• High-density control and glue logic — Use the 48,000 logic elements to consolidate multiple discrete controllers or bridge complex peripheral buses in compact system designs.
• Signal processing and acceleration — sysDSP blocks and on-chip memory enable hardware-accelerated filtering, data aggregation and real-time arithmetic tasks.
• Interface and protocol bridging — Large I/O count and programmable I/O support make the device well suited for protocol translation, board-level bridging and multi-standard interface hubs.
• Memory controller and buffering — Embedded RAM provides local buffering and temporary storage for memory controller implementations and data path staging.

Unique Advantages

• High integration density: 48,000 logic elements allow consolidation of multiple functions into a single device, reducing BOM and board area.
• Ample I/O headroom: 339 I/Os support extensive peripheral and bus connectivity without immediate need for external I/O expanders.
• On-chip memory for latency-sensitive data: Approximately 0.40 Mbits of embedded RAM supports buffering and state retention close to logic, improving throughput for data paths.
• Dedicated DSP resources: sysDSP blocks on the ECP2-50 family enable efficient implementation of multiply-accumulate and signal-processing kernels in hardware.
• Compact, board-friendly package: 484-ball fpBGA (23 × 23 mm) surface-mount package balances pin count and PCB footprint for dense designs.
• Environmentally compliant: RoHS compliance supports regulatory requirements and manufacturing practices.
