LFEC1E-3TN144C

The LFEC1E-3TN144C is an EC Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It provides programmable logic and on-chip resources in a compact 144‑lead LQFP package for board-level integration.

With 1,500 logic elements, 18,432 bits of on-chip RAM and 97 I/O pins, this commercial‑grade device is suited to embedded designs that require configurable digital logic, localized memory and a relatively high I/O count while operating from a low-voltage supply.

Key Features

• Core Logic — 1,500 logic elements arranged to implement custom digital functions and control logic.
• Logic Clusters — 192 CLBs supporting the distribution of logic resources across the device.
• On‑chip Memory — 18,432 bits of RAM for buffering, lookup tables and small data structures without external memory.
• I/O — 97 user I/O pins to support multiple peripheral and interface connections directly from the FPGA.
• Power — Operates from a supply range of 1.14 V to 1.26 V for low-voltage system designs.
• Package & Mounting — 144‑LQFP (supplier device package 144‑TQFP, 20 × 20) in a surface‑mount form factor for space-conscious PCBs.
• Temperature & Grade — Commercial grade operation across 0 °C to 85 °C.
• Environmental — RoHS compliant.

Typical Applications

• Custom logic and glue logic — Implement device-specific control, protocol bridging or glue logic within the 1,500 logic element capacity.
• Memory buffering and LUT-based functions — Use the 18,432 bits of on‑chip RAM for small buffers, FIFOs or lookup tables.
• I/O‑centric interfacing — Leverage 97 I/O pins for sensor interfaces, peripheral control or parallel connections in compact designs.
• Compact board‑level integration — Surface‑mount 144‑LQFP package fits space-constrained PCBs while providing ample logic and I/O resources.

Unique Advantages

• Moderate logic capacity: 1,500 logic elements provide sufficient resources for a wide range of small to mid‑scale programmable tasks.
• Integrated RAM: 18,432 bits of on‑chip memory reduce dependence on external memory for small data handling needs.
• High I/O count: 97 I/Os minimize the need for external expanders when interfacing multiple peripherals.
• Low‑voltage operation: 1.14–1.26 V supply supports integration into low-voltage systems.
• Compact, board‑friendly package: 144‑LQFP (20 × 20) surface‑mount package simplifies integration on dense PCBs.
• RoHS compliant and commercial grade: Meets RoHS requirements and operates across a 0 °C to 85 °C commercial temperature range.
