LFEC20E-4FN484C

The LFEC20E-4FN484C is a commercial-grade FPGA from Lattice Semiconductor’s LatticeEC family, offering a general-purpose, cost-optimized programmable fabric for mainstream embedded and system designs. It combines a mid-range logic capacity with flexible I/O and embedded memory, making it suitable for applications that need configurable logic, on-chip RAM, and a compact 484-ball BGA footprint.

Designed for cost-sensitive and space-constrained designs, this device targets applications that require up to 360 I/Os, a supply voltage near 1.2 V, and commercial temperature operation from 0 °C to 85 °C.

Key Features

• Logic Capacity — Approximately 19,700 logic elements, providing mid-range programmable logic resources for glue logic, protocol handling, and custom control functions.
• On‑Chip Memory — 434,176 total RAM bits (approximately 0.43 Mbits) of embedded memory for FIFOs, small buffers, and state storage.
• I/O Density & Flexibility — 360 user I/Os in a 484-ball fpBGA package (23 × 23 mm), suitable for rich peripheral connectivity in a compact package.
• Power Supply — Operates from 1.14 V to 1.26 V (nominal 1.2 V), aligning with LatticeEC family supply requirements.
• Clocking — Family-level support for up to four analog PLLs for clock multiplication, division, and phase shifting.
• Memory Interface Support — Family-level dedicated DDR memory interface support (up to DDR400) for designs requiring external SDRAM connectivity.
• Package & Mounting — 484-BBGA (supplier package: 484-FPBGA, 23 × 23 mm) with surface-mount assembly.
• Operating Range & Compliance — Commercial grade operation from 0 °C to 85 °C; RoHS compliant.

Typical Applications

• Embedded Control — Implement custom control logic, peripheral glue, and state machines where moderate logic density and on-chip memory are required.
• Communications & Networking — Handle protocol conversion, packet buffering, and interface bridging leveraging the device’s I/O count and embedded RAM.
• Memory Interface & Buffering — Use the device’s family DDR memory interface support and embedded RAM for external memory controllers and buffering tasks.
• Consumer & Industrial Electronics — Add configurable features, sensor aggregation, or user-interface control in commercial-temperature systems.

Unique Advantages

• Balanced Logic and Memory: Mid-range logic (≈19,700 elements) paired with ~0.43 Mbits of embedded RAM provides a practical balance for many mainstream designs without overspecifying resources.
• High I/O Count in a Compact Package: 360 I/Os in a 23 × 23 mm 484-BBGA footprint reduces board area while supporting rich peripheral connectivity.
• Low-Voltage Operation: Narrow supply range (1.14 V–1.26 V) matches modern low-voltage system rails for consistent power integration.
• Flexible Clocking: Up to four analog PLLs (family-level) enable precise clock management for multi‑clock designs and timing-critical interfaces.
• Cost-Optimized Architecture: As part of the LatticeEC family, the device is positioned for cost-sensitive applications that need general-purpose FPGA capabilities without dedicated high-cost function blocks.
• RoHS Compliant: Environmentally compliant manufacturing to support modern electronic product requirements.
