LFEC20E-4FN672I

The LFEC20E-4FN672I is an EC-family field programmable gate array (FPGA) from Lattice Semiconductor Corporation, provided in a 672-ball BGA package for surface-mount assembly. It delivers a balanced set of resources—approximately 19,700 logic elements, 434,176 total RAM bits and 400 user I/Os—targeted at mainstream FPGA applications that require high I/O density and on-chip memory.

Designed to operate across an industrial temperature range and a nominal 1.2 V supply window, this device supports system-level features and interfaces available across the LatticeECP/EC family to simplify integration into cost-sensitive, performance-oriented designs.

Key Features

• Logic Capacity  Approximately 19,700 logic elements to implement medium-complexity digital logic and control functions.
• On‑Chip Memory  434,176 total RAM bits of embedded memory to support buffers, FIFOs and local storage.
• I/O Density  400 user I/O pins available in the 672-ball package for wide interfacing with external devices and peripherals.
• Power  Supply voltage range 1.14 V to 1.26 V (nominal 1.2 V) for core power.
• Package & Mounting  672-BBGA (supplier package: 672-FPBGA, 27 × 27 mm) with surface-mount mounting for compact board designs.
• Temperature & Grade  Industrial grade operation from −40 °C to 100 °C for deployment in temperature-demanding environments.
• Series-Level System Features  LatticeECP/EC family features include flexible programmable I/O buffers supporting multiple standards, dedicated DDR memory interface capability (up to DDR400), up to four analog PLLs, IEEE 1149.1 boundary scan and an SPI boot flash interface (series-level features as documented for the LatticeECP/EC family).

Typical Applications

• Industrial Control  Implement motion control, sensor aggregation and deterministic I/O handling using the device’s sizable logic capacity and industrial temperature rating.
• Communications & Networking  Use high I/O count and on-chip memory for protocol bridging, packet buffering and interface logic in cost-sensitive network equipment.
• Memory Interface and Buffering  Leverage the device’s embedded RAM and series-level DDR interface support for local buffering and memory controller functions.

Unique Advantages

• High I/O count: 400 user I/Os enable broad peripheral and bus connectivity without external multiplexing.
• Generous embedded memory: 434,176 total RAM bits provide on-chip storage for data path buffering and control state.
• Industrial temperature rating: Rated for −40 °C to 100 °C, supporting deployments in demanding thermal environments.
• Compact BGA package: 672-ball FPBGA (27 × 27 mm) offers a high-density footprint for space-constrained boards.
• Series-level system support: Family features such as programmable I/O standards, PLLs, SPI boot and boundary scan help streamline system design and bring-up.
