LFEC3E-3TN100C

The LFEC3E-3TN100C is a commercial-grade FPGA from Lattice Semiconductor’s LatticeECP/EC family. It implements a low-cost FPGA fabric optimized for mainstream applications, combining programmable logic, embedded memory, and flexible I/O to enable compact, configurable designs.

With approximately 3,100 logic elements and roughly 56 Kbits of on-chip RAM, this device targets embedded systems, communications and consumer applications that require moderate logic density, a 67-pin I/O footprint, and surface-mount 100-pin LQFP packaging.

Key Features

• Logic Capacity  Approximately 3,100 logic elements and 384 logic clusters, enabling medium-density logic implementations.
• Embedded Memory  Total on-chip RAM of 56,320 bits (approximately 56 Kbits) for distributed and block memory use in state machines, buffering, and small data stores.
• I/O  67 user I/Os provided in the 100-pin package to support a range of peripheral interfaces and board-level connectivity.
• Flexible I/O Standards (family-level)  Family documentation indicates programmable I/O buffers that support common standards including multiple LVCMOS voltages, LVTTL, SSTL, HSTL and differential I/O options for versatile interfacing.
• Clocking  Family information specifies up to two PLLs for the LFEC3 family, providing clock multiplication, division and phase-shifting capabilities for system timing.
• Power  Core supply operating range from 1.14 V to 1.26 V to meet device power requirements.
• Package & Mounting  100-pin LQFP package; supplier lists 100-TQFP (14 × 14 mm). Device is supplied for surface-mount assembly.
• Operating Conditions  Commercial grade operating temperature range: 0 °C to 85 °C.
• Regulatory  RoHS compliant.

Typical Applications

• Embedded Control  Use as a programmable logic engine for control, sequencing and glue-logic functions in embedded devices where medium logic density and compact packaging are required.
• Communications Equipment  Implement interface bridging, protocol adaptation or custom peripheral logic leveraging 67 I/Os and the family’s programmable I/O standards.
• Consumer Electronics  Integrate custom feature logic, user-interface control, and small buffering tasks while maintaining a low-cost BOM and surface-mount package.
• Memory Interface and Prototyping  Leverage the family’s dedicated DDR memory support and on-chip memory for prototyping memory-related interfaces and system-level validation.

Unique Advantages

• Balanced Logic and Memory  Approximately 3,100 logic elements paired with roughly 56 Kbits of on-chip RAM provides a practical balance for mainstream designs without excess capacity.
• Compact, Surface-Mount Package  100-pin LQFP/TQFP packaging (14 × 14 mm supplier footprint) reduces board area while providing a generous set of I/Os for mixed-signal and digital peripherals.
• Flexible I/O Options  Family-level programmable I/O supports a broad set of standards, simplifying board-level interface design and enabling reuse across multiple designs.
• Deterministic Supply Requirements  A narrow core supply range (1.14 V–1.26 V) simplifies power rail design and qualification within target systems.
• Commercial-Grade Thermal Range  Specified 0 °C to 85 °C operating range aligns with many consumer and communications deployments.
• RoHS Compliance  Meets lead-free and restricted-substance directives to support modern manufacturing processes.
