Key Features

• Logic Capacity — 1500 logic elements and 192 logic blocks, suitable for small to medium-sized logic designs and control functions.
• On-chip Memory — Total on-chip RAM of 18,432 bits (approximately 18 Kbits) to implement local storage, FIFOs or small buffers without external memory.
• I/O Count and Flexibility — 97 I/Os available in a 144-pin package to support multiple interfaces and peripheral connections.
• Voltage Supply — Operates from 1.14 V to 1.26 V, aligning with low-voltage FPGA system rails.
• Programmable I/O Standards (family capability) — Family-level programmable sysI/O buffer support for a wide range of I/O standards, enabling flexible interfacing options for common signaling requirements.
• Clocking and PLLs (family capability) — Family includes analog PLL resources for clock multiplication, division and phase shifting; LFEC1 devices are specified with two PLLs.
• Package — Surface-mount 144-LQFP (supplier package noted as 144-TQFP 20×20 mm) offers a compact footprint for space-constrained PCBs.
• Operating Range and Grade — Commercial grade with operating temperature from 0 °C to 85 °C.
• RoHS Compliant — Conforms to RoHS environmental requirements.

Typical Applications

• Embedded Control — Implement control logic, state machines and peripheral glue logic where a compact FPGA with on-chip RAM and multiple I/Os simplifies design.
• Interface Bridging — Use the device’s programmable I/O capabilities to bridge between different bus standards and peripheral interfaces.
• Sensor and Actuator Interfaces — Aggregate and preprocess sensor data or manage actuator-driven control loops with local logic and RAM.
• Low- to Mid-density Custom Logic — Deploy custom packet processing, protocol handling or simple DSP-like functions within the available logic and memory resources.

Unique Advantages

• Compact, production-ready package: 144-LQFP/TQFP package provides a small PCB footprint while offering 97 I/Os for flexible board-level integration.
• Low-voltage operation: Narrow supply range (1.14 V–1.26 V) supports designs targeting modern low-voltage systems and simplifies power-rail planning.
• Balanced logic and memory: 1500 logic elements combined with approximately 18 Kbits of on-chip RAM allows efficient implementation of control logic and modest buffering without external SRAM.
• Family-level ecosystem: The Lattice ECP/EC family supports programmable I/O standards and PLLs, enabling scalable design practices and reuse across devices in the series.
• Regulatory and environmental compliance: RoHS compliance supports environmentally sensitive product requirements.
