LFE2-12E-5F256C

The LFE2-12E-5F256C is a commercial-grade ECP2 family FPGA from Lattice Semiconductor, delivered in a 256-ball fpBGA (17 × 17 mm) package for surface-mount assembly. This device provides a mid-range FPGA fabric with approximately 12,000 logic elements, rich I/O, and on-chip memory to support system integration tasks in communications, control, and embedded processing designs.

Key device-level specifications include 193 I/Os, approximately 226 Kbits of embedded RAM, a 1.14 V–1.26 V core supply window, and an operating temperature range of 0 °C to 85 °C. The device is RoHS compliant.

Key Features

• Core logic – 1,500 logic blocks totaling approximately 12,000 logic elements for implementing mid-density logic functions and control paths.
• Embedded memory – Approximately 226 Kbits of on-chip RAM to support buffers, FIFOs, and small data-storage needs within the FPGA fabric.
• I/O density and flexibility – 193 user I/Os provided in a 256-ball fpBGA package for high-pin-count interface routing and peripheral connectivity.
• Power and package – 256-FPBGA (17 × 17 mm) package, surface-mountable; typical core supply range 1.14 V to 1.26 V.
• Operating range and grade – Commercial grade operation from 0 °C to 85 °C suitable for a wide range of general-purpose embedded applications.
• Regulatory compliance – RoHS compliant for environmental and assembly process compatibility.
• Family-level architecture – Part of the Lattice ECP2/M family which includes features such as enhanced DSP blocks, flexible embedded memory options, programmable PLLs/DLLs, and a wide set of programmable I/O standards (as described in the family datasheet).

Typical Applications

• Embedded control – Implement microcontroller offload, peripheral bridging, and real-time control logic using the device’s logic and memory resources.
• Data buffering and protocol bridging – Use on-chip RAM and dense I/O to implement interface translators, packet buffers, and intermediate data-handling tasks.
• Signal processing acceleration – Leverage the family’s DSP-oriented architecture for multiply-accumulate and medium-scale signal processing blocks.

Unique Advantages

• Balanced mid-range capacity – Approximately 12,000 logic elements and 193 I/Os provide a capable platform for designs that need more integration than small FPGAs without moving to larger form factors.
• Compact BGA package – 256-ball fpBGA (17 × 17 mm) enables high I/O in a small PCB footprint for space-constrained applications.
• Flexible embedded memory – About 226 Kbits of on-chip RAM reduces external memory dependency for many buffering and state-storage tasks.
• Commercial-grade robustness – 0 °C to 85 °C operating range and RoHS compliance align with typical commercial embedded product requirements.
• Family ecosystem – Part of the Lattice ECP2/M family, which is supported by the family datasheet features and design tools for implementation and debugging.
