LFEC1E-3TN100I

The LFEC1E-3TN100I is an EC-family Field Programmable Gate Array from Lattice Semiconductor Corporation, offering a general-purpose FPGA fabric designed for cost-sensitive, mainstream applications. As a member of the LatticeECP/EC family, this device targets compact embedded designs that require a balance of logic capacity, on-chip memory and flexible I/O in a small surface-mount package.

Built for industrial operating conditions, the device provides a low-voltage core supply and integrated system-level features such as PLLs, boundary-scan support and SPI boot capability to simplify board integration and system bring-up.

Key Features

• Logic Capacity  Approximately 1,500 logic elements with 192 logic blocks (PFUs) to implement small-to-medium sized designs.
• On-chip Memory  Approximately 18 Kbits of embedded RAM (18,432 total RAM bits) for distributed or block memory needs within the FPGA fabric.
• I/O Flexibility  67 I/O pins available from the 100-pin package, supporting a wide range of interface options defined by the LatticeECP/EC family.
• Power Supply  Core supply specified between 1.14 V and 1.26 V to match low-voltage system designs.
• Package & Mounting  100-pin LQFP/TQFP (14 × 14 mm) surface-mount package for compact PCB implementations.
• Industrial Temperature Grade  Rated for operation from −40 °C to 100 °C, suitable for industrial temperature environments.
• Clocking & System Support  Includes analog PLL support (2 PLLs for this device as indicated in family selection) plus system features such as IEEE 1149.1 boundary scan and SPI boot flash interface.
• Design Ecosystem  Part of the LatticeECP/EC family—compatible with the ispLEVER tool suite and supported IP cores for efficient design implementation.
• Compliance  RoHS compliant.

Typical Applications

• Industrial Control  Logic consolidation, deterministic I/O handling and compact control functions in industrial equipment where extended temperature operation is required.
• Embedded Systems  Custom glue logic, protocol adaptation and peripheral management in space-constrained embedded designs.
• Memory Interface and Buffering  Local memory and interface logic where modest on-chip RAM and PLL-based clocking simplify DDR and synchronous interface implementations.
• Communications and Networking  Interface bridging, signal conditioning and custom protocol logic using flexible I/O and programmable fabric.

Unique Advantages

• Compact, manufacturable package: The 100-pin LQFP/TQFP footprint offers a small board area and surface-mount assembly for high-density designs.
• Industrial temperature rating: Specified −40 °C to 100 °C operation enables deployment in harsher environments without additional thermal qualification.
• Low-voltage core operation: 1.14–1.26 V supply simplifies power-rail planning in modern low-voltage systems.
• Integrated system features: On-chip PLLs, boundary scan and SPI boot support streamline board bring-up and in-system programming.
• Balanced resources for mainstream designs: A practical combination of logic elements, embedded RAM and I/O count tailored to cost-sensitive, mainstream applications.
• RoHS compliant: Aligns with environmental and manufacturing requirements for many commercial and industrial products.
