LFE3-95E-7FN484I

The LFE3-95E-7FN484I is a Lattice Semiconductor ECP3 family field programmable gate array (FPGA) featuring 92,000 logic elements in a 484-ball BGA package. Built around the ECP3 architecture, this device combines high logic density, on-chip memory, embedded DSP resources and flexible I/O to address high-performance embedded and communications applications.

With 295 user I/Os, embedded SERDES capability described by the ECP3 family, and approximately 4.53 Mbits of on-chip RAM, this industrial-grade device is suited for designs that require substantial logic, on-chip memory and multi-protocol serial connectivity in a compact surface-mount package.

Key Features

• Core Logic  92,000 logic elements provide a high-density programmable fabric for complex control, protocol and signal-processing logic.
• Embedded Memory  Total on-chip RAM of approximately 4.53 Mbits to support large buffering, state storage and embedded data structures.
• DSP and Arithmetic  Architecture includes the ECP3 family’s enhanced sysDSP capabilities (family-level features) for multiply–accumulate and high-performance arithmetic.
• High-Speed Serial and I/O  Part of the ECP3 family that supports embedded SERDES and a wide range of programmable I/O standards, enabling multi-protocol serial interfaces and source-synchronous links.
• Clocking and Timing  Family-level support for multiple PLLs and DLLs provides flexible clock generation and deskewing options for system timing.
• Package and Mounting  484-ball BGA (supplier device package: 484-FPBGA, 23×23 mm) designed for surface-mount assembly.
• Power and Temperature  Core supply voltage range of 1.14 V to 1.26 V and industrial operating temperature range of -40 °C to 100 °C for robust field operation.
• Industrial Grade and Compliance  Specified as Industrial grade and RoHS compliant.

Typical Applications

• High-speed serial communications  Implement PCI Express, Ethernet and other multi-gigabit protocols using the ECP3 family’s SERDES and programmable I/O features.
• Signal processing and converters  Use sysDSP resources and on-chip RAM for ADC/DAC interfacing, digital filtering and real-time signal conditioning.
• Memory interface and buffering  Support DDR/DDR2/DDR3-type source-synchronous memory interfaces and large on-chip buffers for data staging and throughput smoothing.
• Embedded control and protocol bridging  Combine high logic density and flexible I/O to implement protocol conversion, real-time control logic and complex state machines.

Unique Advantages

• High integration density: 92,000 logic elements and approximately 4.53 Mbits of embedded memory reduce external component count and simplify PCB design.
• Broad I/O and serial support: 295 user I/Os and ECP3 family SERDES and I/O standards support enable a wide range of interface options without external PHYs.
• Industrial operating range: Rated from -40 °C to 100 °C to meet demanding environmental requirements.
• Compact, manufacturable package: 484-ball FPBGA (23×23 mm) surface-mount package provides high pin density in a board-friendly form factor.
• Precision power domain: Narrow core voltage range (1.14 V to 1.26 V) supports stable core operation and predictable power budgeting.
• System-level support (family features): ECP3 family tooling and utilities provide configuration, debug and integration aids referenced for this device class.
