LFEC1E-4TN100C

The LFEC1E-4TN100C from Lattice Semiconductor is a compact, low-cost EC-family FPGA offered in a 100-pin surface-mount LQFP package. Built for mainstream embedded and cost-sensitive designs, it provides roughly 1,500 logic elements, 18,432 bits of on-chip RAM, and 67 user I/Os in a small 14 × 14 mm package footprint.

Its architecture targets flexible interfacing and system integration, with configurable I/O options, on-chip clocking resources, and support for DDR memory interfaces at the family level, making it suitable for a wide range of general-purpose FPGA tasks where footprint and cost are primary considerations.

Key Features

• Logic Capacity  Approximately 1,500 logic elements and 192 logic blocks provide the core programmable fabric for control, glue logic, and moderate-complexity functions.
• On-chip Memory  18,432 bits (approximately 18 Kbits) of embedded RAM for data buffering, small LUT-based memories, and state storage.
• I/O Density & Flexibility  67 user I/O pins in a 100-pin LQFP package enable multiple peripheral interfaces and board-level connectivity in a compact footprint.
• Package & Mounting  100-pin LQFP (surface mount); supplier package reference 100-TQFP (14 × 14 mm) supports compact PCB layouts and standard SMT assembly.
• Power  Core supply voltage ranges from 1.14 V to 1.26 V, enabling low-voltage operation common in modern embedded systems.
• Clocking  Device-family support includes on-chip PLLs for clock multiply/divide and phase shifting; LFEC1 devices include two PLLs at the family level.
• Memory Interface Support (Family)  Family-level documentation specifies dedicated DDR memory interface support up to DDR400 (200 MHz) for systems requiring external DRAM.
• Temperature & Grade  Commercial-grade operation from 0 °C to 85 °C and RoHS compliance for regulatory and manufacturing requirements.
• Design Ecosystem (Family)  Lattice's ispLEVER design tools and available ispLeverCORE IP (family-level) support development, synthesis, and implementation workflows.

Typical Applications

• Embedded Control  Implement glue logic, protocol conversion and peripheral controllers in compact embedded systems where board space and cost are constrained.
• Consumer Electronics  Integrate custom control and interface functions in consumer devices that require a small-footprint FPGA with multiple I/Os.
• Communications & Networking  Use as protocol bridges, PHY interfacing logic, or packet-handling assist in space-limited network modules, leveraging the device I/O density.
• Instrumentation & Test  Provide flexible I/O and on-chip buffering for measurement front-ends, data aggregation, and custom signal-processing control paths.

Unique Advantages

• Compact, high-density I/O in a small package: The 100-pin LQFP delivers 67 usable I/Os and programmable logic in a 14 × 14 mm footprint for tight PCB real estate.
• Low-voltage core operation: 1.14–1.26 V supply range supports modern low-power system architectures and power-rail planning.
• On-chip RAM for local buffering: Approximately 18 Kbits of embedded memory enables local data storage and small FIFO/scratchpad implementations without external memory.
• Commercial temperature rating and RoHS compliance: 0 °C to 85 °C operation and RoHS conformity simplify component selection for consumer and general-purpose products.
• Development tools and IP (family-level): ispLEVER tools and available ispLeverCORE IP help accelerate design implementation and reduce time-to-market.
• Family-level DDR support and clocking: Documentation for the family includes dedicated DDR interface capability and on-chip PLLs to simplify system clocking and memory interfacing.
