LFEC1E-3T100C

The LFEC1E-3T100C is a commercial-grade Field Programmable Gate Array (FPGA) from Lattice Semiconductor’s LatticeECP/EC family. It provides a compact, low-cost FPGA fabric with programmable logic, embedded memory, and flexible I/O suitable for mainstream, cost-sensitive designs.

With 1,500 logic elements, approximately 18.4 Kbits of on-chip RAM and 67 I/Os in a 100-pin LQFP package, the device addresses small to medium-density logic integration, interface bridging and embedded control applications where board space, power and cost are important considerations.

Key Features

• Core logic  1,500 logic elements provide the programmable fabric for implementing custom logic, glue functions and small data-paths.
• Logic block count  192 logic blocks (PFU/PFF rows/columns as specified for the family) to support partitioned designs and floorplanning.
• Embedded memory  Approximately 18,432 bits (≈18.4 Kbits) of on-chip RAM for small buffers, FIFOs and state storage.
• I/O flexibility  67 general-purpose I/Os available in the 100-pin package for peripheral interfaces, control signals and bus connections.
• Voltage and power  Core supply range of 1.14 V to 1.26 V to match system power rails and ensure predictable core operation.
• Clocking  Family architecture includes integrated PLL resources (family table indicates multiple PLLs) for clock multiplication, division and phase control.
• Memory interface support  Family-level support for dedicated DDR memory interfaces (up to DDR400) enables direct implementation of common external memory subsystems.
• Package & mounting  100-pin low-profile quad flat package (100-LQFP / 100-TQFP, 14 × 14 mm) with surface-mount mounting for compact PCB layouts.
• Commercial temperature rating  Operates from 0 °C to 85 °C and is specified as commercial grade for standard embedded and consumer applications.
• RoHS compliant  Meets RoHS environmental requirements for lead-free assembly and regulatory compliance.

Typical Applications

• Embedded control and system glue logic  Implement custom control state machines, peripheral bridging and protocol translation in compact, low-cost systems.
• Memory interface and buffering  Use on-chip RAM and family DDR support to implement memory controllers, buffers or temporary storage for external memory subsystems.
• Consumer and commercial electronics  Integrate into cost-sensitive consumer devices and commercial equipment where moderate logic density and a compact package are required.
• Prototyping and evaluation  Rapidly prototype small FPGA designs or validate system-level functions before scaling to larger devices in the family.

Unique Advantages

• Compact, production-ready package: 100-pin LQFP/TQFP package balances PCB area and pin count for space-constrained boards.
• Balanced logic and memory: 1,500 logic elements combined with ~18.4 Kbits of embedded RAM supports common control and buffering tasks without external SRAM.
• Generous I/O count for size: 67 I/Os provide ample connectivity for peripherals, displays, sensors and external buses in a small footprint.
• Family-level system features: The LatticeECP/EC family provides integrated clocking (PLLs), DDR memory interface options and a flexible I/O buffer architecture to simplify system design.
• Commercial-grade ready: Specified for 0 °C to 85 °C operation and RoHS compliance for mainstream product lines and volume production.
• Low-cost mainstream option: Designed to deliver the essential FPGA building blocks for cost-sensitive applications where efficiency and integration matter.
