LFEC3E-5QN208C

The LFEC3E-5QN208C is a Lattice Semiconductor EC family FPGA delivering a balance of programmable logic, on-chip RAM and I/O in a 208-pin PQFP package. Built on the LatticeECP/EC architecture, the device targets mainstream, cost-sensitive applications that require flexible I/O, moderate logic density and integrated memory resources.

This device provides 3,100 logic elements, approximately 56 Kbits of on-chip RAM, and 145 I/O pins in a 208-BFQFP (28 × 28 mm) surface-mount package, with a 1.14 V to 1.26 V supply range and commercial temperature qualification (0 °C to 85 °C).

Key Features

• Core Logic 3,100 logic elements suitable for mainstream FPGA designs requiring moderate logic density.
• On-chip Memory Total RAM of 56,320 bits (approximately 55 Kbits) for embedded data buffering and small on-chip storage needs.
• I/O and Packaging 145 I/O pins in a 208-BFQFP (28 × 28 mm) supplier device package; surface-mount mounting simplifies PCB assembly for compact systems.
• Supply Voltage Operates from 1.14 V to 1.26 V (nominal 1.2 V), matching low-voltage system requirements.
• Commercial Temperature Grade Rated for 0 °C to 85 °C operation for standard commercial and industrial-adjacent applications.
• PLLs and Clocking Family support includes analog PLLs for clock multiply/divide and phase shifting; the LFEC3 device provides two PLLs for flexible clock management.
• Flexible I/O Standards Family-level sysI/O buffers support a wide range of standards (LVCMOS, LVTTL, SSTL, HSTL, PCI, LVDS, LVPECL and others), enabling diverse interface options.
• System Features Family-level capabilities include SPI boot flash interface and IEEE 1149.1 boundary scan; on-chip debug/trace support is available in the series.
• Compliance Device is RoHS compliant.

Typical Applications

• Mainstream Embedded Logic Implement control and glue logic where moderate gate count and plentiful I/O are required in a compact PQFP package.
• Memory Interface and Buffering Use the device’s on-chip RAM and family DDR interface support for cost-sensitive memory buffering and interface tasks.
• Protocol and I/O Conversion Leverage the flexible sysI/O buffer standards to bridge between differing voltage and signaling families in embedded systems.

Unique Advantages

• Compact, High-I/O Package: 145 I/Os in a 208-BFQFP (28 × 28 mm) package provide a dense pinout without requiring a BGA.
• Balanced Logic and Memory: 3,100 logic elements combined with approximately 55 Kbits of on-chip RAM support a wide range of mid-size designs.
• Low-voltage Operation: 1.14 V to 1.26 V supply compatibility fits low-voltage system architectures.
• Design and Tooling Ecosystem: Family-level design flow and ispLEVER tool support and pre-designed IP cores accelerate development and reduce implementation time.
• Commercial Temperature and RoHS Compliance: Rated 0 °C to 85 °C and RoHS compliant for standard commercial product deployments.
