LFEC33E-4FN484I

The LFEC33E-4FN484I is an EC-family FPGA from Lattice Semiconductor Corporation engineered for mainstream, cost-conscious designs that require mid-range logic capacity and flexible I/O. It combines a dense logic fabric with on-chip RAM and configurable I/O support, making it suitable for embedded systems, industrial control, memory-interface designs and other applications that benefit from integrated FPGA functionality.

Key Features

• Logic Fabric Approximately 32,800 logic elements provide mid-range integration density for complex glue logic, protocol handling and control functions.
• On‑Chip Memory Approximately 434,176 bits of embedded RAM support distributed and block memory configurations for buffering, FIFOs and state storage.
• I/O and Interface Flexibility 360 user I/Os with a programmable sysI/O™ buffer supporting a wide range of standards, including LVCMOS (3.3/2.5/1.8/1.5/1.2 V), LVTTL, SSTL, HSTL, PCI, LVDS, Bus‑LVDS, LVPECL and RSDS.
• DDR Memory Support Family-level dedicated DDR interface logic implements memory interfaces up to DDR400 (200 MHz).
• Clocking and System Features Up to four analog PLLs per device for clock multiplication, division and phase shifting; system-level support includes IEEE 1149.1 boundary scan, SPI boot flash interface and ispTRACY™ internal logic analyzer capability.
• Package and Power 484-ball fpBGA (484-FPBGA, 23 × 23 mm) surface-mount package; nominal supply range 1.14 V to 1.26 V.
• Industrial Grade and Temperature Industrial-grade device rated for operation from −40 °C to 100 °C.
• Environmental Compliance RoHS compliant.
• Design Ecosystem Supported by the ispLEVER design tool suite and available ispLeverCORE™ IP modules for faster integration and design reuse.

Typical Applications

• Embedded Systems — Mid-range embedded controllers and platform logic that require integrated RAM, flexible I/O and moderate logic density.
• Memory Interfaces — Designs needing dedicated DDR support up to DDR400 for external memory interfacing and buffering.
• Industrial Control — Industrial-grade temperature range and abundant I/Os for sensor interfacing, motor control and automation logic.
• Communications and Networking — Protocol bridging and interface aggregation where flexible I/O standards (LVDS, PCI, LVPECL) are required.

Unique Advantages

• High logic density: Approximately 32,800 logic elements enable consolidation of multiple discrete functions into a single FPGA, reducing component count.
• Substantial on-chip RAM: Approximately 0.43 Mbits of embedded memory supports buffering and state machines without immediate need for external SRAM.
• Large I/O complement: 360 I/Os provide the pin count needed for complex peripheral interfaces and multi-channel designs.
• Robust industrial operation: Rated from −40 °C to 100 °C and offered in a compact 484-ball fpBGA package suitable for surface-mount assembly.
• Flexible interfacing: Programmable I/O buffers and dedicated DDR support simplify integration with a wide range of peripherals and memory devices.
• Toolchain and IP support: ispLEVER and ispLeverCORE modules accelerate development, lowering design risk and time to market.
