LFEC3E-4TN100C

The LFEC3E-4TN100C is an EC (EConomy) family FPGA in a 100-pin surface-mount package optimized for mainstream, cost-sensitive designs. The device provides a balanced combination of programmable logic, on-chip memory and flexible I/O suitable for consumer and commercial embedded systems that require moderate logic density and compact packaging.

Built on the LatticeECP/EC family architecture, the LFEC3E-4TN100C integrates LUT-based logic, distributed and embedded memory, PLLs and a range of I/O options to support system-level interfacing and memory connectivity.

Key Features

• Logic Capacity  3,100 logic elements and 384 logic blocks provide mid-range programmable logic resources for glue logic, protocol handling and control functions.
• Embedded Memory  56,320 bits of total on-chip RAM for lookup tables, FIFOs and small data buffers.
• I/O Resources  67 user I/Os in a 100-pin package to support device-level interfaces and peripheral connectivity.
• Flexible I/O Standards (family-level)  Family support for a wide range of interfaces including multiple LVCMOS levels, LVTTL, SSTL, HSTL, LVDS and related standards for mainstream I/O requirements.
• Clocking  Integrated PLL resources (family-level) to support clock multiplication, division and phase shifting for system timing.
• Power  Core supply operating range from 1.14 V to 1.26 V.
• Package and Mounting  100-pin LQFP surface-mount package (supplier listing: 100‑TQFP, 14 × 14 mm) for compact PCB designs.
• Temperature and Grade  Commercial grade operation from 0 °C to 85 °C.
• Compliance  RoHS compliant.

Typical Applications

• Consumer and Commercial Electronics  Implement control logic, peripheral interfaces and glue logic in compact, cost-sensitive products.
• Embedded Control  Use for device control, protocol bridging and user-interface management where moderate logic and on-chip memory suffice.
• Memory Interface and Buffering  Support system-level memory interfaces (family-level DDR support referenced in family datasheet) and small buffering tasks using on-chip RAM.
• Custom I/O and Interface Translation  Leverage the device’s flexible I/O capability to implement custom signaling and translation between subsystems.

Unique Advantages

• Balanced Mid-Range Logic:  3,100 logic elements and 384 logic blocks deliver a practical balance of resources for mainstream embedded designs.
