LFEC1E-3TN100C

The LFEC1E-3TN100C is a commercial-grade LatticeECP/EC family FPGA offering a compact, cost-conscious FPGA fabric suitable for mainstream applications. It integrates approximately 1,500 logic elements, about 18 Kbits (18,432 bits) of on-chip RAM, and 67 I/Os in a 100-pin LQFP/TQFP package.

Designed for low-cost, mainstream designs, the device supports common system-level features from the LatticeECP/EC family such as PLLs, dedicated DDR memory interface capability, and a 1.2 V-class supply range, enabling efficient integration into a wide range of commercial embedded systems.

Key Features

• Logic Capacity — Approximately 1,500 logic elements and 192 logic blocks provide the core programmable fabric for implementing custom logic and control functions.
• On-chip Memory — Approximately 18 Kbits (18,432 bits) of embedded RAM for small data buffers, FIFOs, and control-state storage.
• I/O Density — 67 user I/Os offered in the 100-pin package enable a variety of peripheral and interface connections in a compact footprint.
• Power Supply — Operates from a supply range of 1.14 V to 1.26 V (1.2 V class), matching low-voltage system rails common in modern designs.
• Analog and Clocking Support — Family-level support includes up to two PLLs for clocking, and dedicated DDR memory interface capability (implements interface up to DDR400/200 MHz as part of the family feature set).
• Packaging — Supplied in compact 100-pin packages: 100-LQFP (package case) and 100-TQFP (14 × 14 mm supplier device package) for space-constrained boards.
• Commercial Temperature Grade — Rated for 0 °C to 85 °C operation and specified as commercial grade.
• RoHS Compliant — Meets RoHS environmental requirements for lead-free assembly and materials.

Typical Applications

• Mainstream embedded systems — Implement control logic, glue logic, and protocol handling in cost-sensitive commercial products that benefit from a compact FPGA solution.
• Memory interface designs — Use the family’s dedicated DDR memory support to implement external memory controllers or buffers up to DDR400 (200 MHz).
• Prototyping and IP integration — Integrate pre-built IP blocks and iterate designs using the LatticeECP/EC family tool flow and ispLEVER-compatible IP cores.
• Compact I/O expansion — Add programmable I/O and custom interface logic in space-constrained boards using the 100-pin LQFP/TQFP package.

Unique Advantages

• Compact, programmable fabric: 1,500 logic elements and 67 I/Os in a 100-pin package reduce board area while providing flexible logic resources.
• On-chip memory for real-time buffering: Approximately 18 Kbits of embedded RAM supports small FIFOs, state machines, and buffer storage without external SRAM.
• Low-voltage operation: 1.14 V to 1.26 V supply range aligns with 1.2 V system rails to simplify power supply design.
• System-level clocking: Up to two PLLs (family-level specification) enable clock management, multiplication/division and phase adjustments for synchronous designs.
• Family scalability and migration: The LatticeECP/EC family offers density options and migration paths for designs that may need increased capacity within the same architecture.
• Regulatory and environmental compliance: RoHS compliance supports modern manufacturing and environmental requirements.
