The Lattice LFE2M35SE-5FN484C is a distinguished member of Lattice Semiconductor's LatticeECP2/M family, representing a highly optimized low-power, high-performance FPGA solution. Engineered for cost-sensitive and power-conscious applications, this device balances capability with efficiency, making it a compelling choice for a wide range of embedded and portable designs.
At its core, this FPGA features 34,816 Look-Up Tables (LUTs) alongside 483,840 bits of embedded block RAM, providing ample resources for implementing complex logic, data buffering, and FIFOs. A key architectural advantage is its integration of dedicated DSP blocks, which are essential for accelerating arithmetic-intensive operations commonly found in signal processing, image processing, and communications workloads. This hardware-level support enables efficient implementation of filters, multipliers, and other mathematical functions without overburdening the general-purpose logic fabric.
The device is housed in a fine-pitch 484-ball FineLine BGA (fnBGA) package, a form factor designed to accommodate high I/O density while maintaining a compact PCB footprint. This package supports a wide range of single-ended and differential I/O standards, including LVCMOS, LVTTL, SSTL, HSTL, and LVDS. The robust I/O structure allows for flexible interfacing with processors, memory devices, sensors, and communication interfaces, making the FPGA an ideal system integration platform.
True to its lineage, the LFE2M35SE is architected for exceptionally low static and dynamic power consumption. This is achieved through advanced 90nm process technology and thoughtful architectural choices like programmable low-power modes. This characteristic is paramount for battery-operated devices, environmentally sensitive systems, or any application where thermal management and energy efficiency are critical design constraints.
The device operates at a core voltage of 1.2V with a speed grade of -5, indicating its performance capabilities. For configuration, it supports versatile interfaces such as SPI flash, parallel bus, and through its built-in JTAG port, which also serves as the primary conduit for in-system programming and debugging. This flexibility simplifies the boot process and integration into various system architectures.
