LFEC6E-5FN484C

The LFEC6E-5FN484C is a commercial-grade EC family FPGA providing a mid-range logic fabric optimized for mainstream, cost-sensitive applications. The device integrates approximately 6,100 logic elements, roughly 94 Kbits of on-chip RAM, and 224 general-purpose I/O pins in a compact 484-ball BGA (23 × 23 mm) package for high-density board designs.

Designed for general-purpose programmable logic tasks, this FPGA balances integration and I/O capability while operating from a low-voltage supply (1.14 V to 1.26 V). It is intended for commercial embedded systems, communications equipment, and other applications that require moderate logic density and flexible I/O.

Key Features

• Logic Capacity — Approximately 6,100 logic elements for implementing combinatorial and sequential logic functions.
• On-chip Memory — Total on-chip RAM of 94,208 bits (approximately 94 Kbits) for distributed and embedded memory resources.
• I/O Density — 224 I/O pins to support wide peripheral and bus interfacing needs in compact designs.
• Power — Nominal supply window from 1.14 V to 1.26 V suited to low-voltage system environments.
• Packaging & Mounting — 484-ball fpBGA package (23 × 23 mm) in a surface-mount form factor for high-density PCB layouts.
• Operating Range — Commercial operating temperature range of 0 °C to 85 °C.
• PLLs and Clocking — Family-level support includes analog PLLs for clock management (device implements two PLLs as per family selection guidance).
• Design Ecosystem — Series datasheet documents ispLEVER design tool support and available pre-designed IP to accelerate development.
• Compliance — RoHS compliant for environmental conformity in commercial products.

Typical Applications

• Commercial Embedded Systems — Implement control logic, peripheral interfaces, and custom state machines in space-constrained boards.
• Communications Equipment — Protocol bridging, framing, and interface logic using the device’s 224 I/Os and on-chip memory.
• Memory Interface Support — Implement DDR interface logic and related controllers leveraging family-level dedicated DDR support.
• Consumer and Industrial Electronics (Commercial Grade) — Feature control, data aggregation, and I/O expansion where commercial temperature grading is acceptable.

Unique Advantages

• Balanced Logic and Memory: About 6,100 logic elements combined with ~94 Kbits of on-chip RAM to handle moderate complexity designs without external memory for many functions.
