The LFE2M20E-6FN484I is an industrial-grade ECP2M family FPGA in a 484-ball BGA package. It delivers a mid-range programmable logic resource set with on-chip memory and extensive I/O for system integration in communications, industrial, and embedded applications.

As a member of the LatticeECP2/M family, this device brings architecture-level features from that family—including advanced DSP blocks, flexible memory resources, and high-speed serial interface support—combined with a compact 484‑BBGA footprint and RoHS compliance.

Key Features

• Core Logic  19,000 logic elements to implement medium-complexity programmable logic and control functions.
• Embedded Memory  Approximately 1.25 Mbits (1,246,208 bits) of on-chip RAM for data buffering, FIFOs, and state storage.
• I/O Density  304 user I/Os provide broad interface connectivity for multi-channel designs and board-level integration.
• High-Speed Transceivers (family)  The LatticeECP2M family includes embedded SERDES with data-rate capability from 250 Mbps to 3.125 Gbps for protocols such as PCI Express and Ethernet (as documented for the family).
• DSP and Arithmetic Resources  Family-level sysDSP blocks support high-performance multiply-accumulate operations for signal processing tasks.
• Clocking  Family architecture provides analog PLLs and DLLs (GPLLs/SPLLs) for flexible clock multiplication, division and phase control.
• Programmable I/O Standards  Family-level sysI/O buffers support a wide range of interfaces (LVTTL/LVCMOS, LVDS, SSTL, HSTL and others) to simplify interfacing with diverse peripherals.
• Configuration Options  Family supports flexible configuration modes including SPI boot flash interface and dual boot images; optional bitstream encryption is available on “S” versions of the family.
• Power and Temperature  Device supply range 1.14 V to 1.26 V and rated for industrial operation from -40°C to 100°C.
• Package & Mounting  484‑BBGA (484‑FPBGA, 23 × 23 mm) surface-mount package for compact board-level integration.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Networking & Communications  Implement protocol processing, packet buffering and SERDES-based links for 1GbE/SGMII and other serial interfaces (family-level support).
• Industrial Automation  Control, bridging and I/O consolidation in harsh environments using the device’s industrial temperature rating and broad I/O count.
• High‑Speed Data Acquisition  On-chip memory and DSP resources enable pre-processing, buffering and interface logic for ADC/DAC front ends and source‑synchronous data paths.
• Embedded System Integration  Combine logic, memory and diverse I/O standards to reduce BOM and simplify board-level integration in embedded designs.

Unique Advantages

• Substantial Logic Capacity: 19,000 logic elements provide headroom for control, glue logic and moderate compute tasks without external FPGA escalation.
• Rich I/O Count: 304 I/Os enable multi-channel connectivity and flexible partitioning of interfaces across banks.
• On‑Chip Memory and DSP: Approximately 1.25 Mbits of embedded RAM plus family DSP blocks reduce dependence on external memory and accelerators.
• Industrial Reliability: Rated from -40°C to 100°C for deployment in industrial environments.
• Compact, Surface‑Mount Package: 484‑BBGA (23×23 mm) package balances pin count and PCB footprint for space‑constrained designs.
• Family Ecosystem: Access to LatticeECP2/M family features such as programmable clocking, source‑synchronous I/O support and configurable boot options for system-level flexibility.
