LFE2-35E-6F484C

The LFE2-35E-6F484C is an ECP2 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation designed for commercial-grade applications. It provides a mid-range programmable logic resource with 32,000 logic elements, approximately 0.34 Mbits of embedded memory, and a large I/O count in a compact surface-mount 484-BBGA package.

With a low-voltage supply range and a standard commercial operating temperature span, this device targets designs that require substantial logic capacity, dense I/O interfacing, and compact packaging for space-constrained PCBs.

Key Features

• Core Logic 32,000 logic elements suitable for implementing custom digital functions and moderate complexity designs.
• Embedded Memory Approximately 0.34 Mbits of on-chip RAM (339,968 total RAM bits) for buffering, state storage, and small data structures.
• I/O Capacity 331 programmable I/O pins to support high-density interfacing and multiple peripheral connections.
• Power Operates from a supply voltage range of 1.14 V to 1.26 V, enabling low-voltage system designs.
• Package & Mounting 484-BBGA package (supplier device package: 484-FPBGA 23×23) in a surface-mount form factor suitable for compact PCBs.
• Temperature & Grade Commercial grade device rated for 0 °C to 85 °C operating temperature.
• Environmental Compliance RoHS compliant to meet common regulatory requirements for commercial electronics.

Typical Applications

• I/O-intensive commercial systems — Leverage 331 I/Os to implement dense interfacing and protocol bridging in commercial products.
• Embedded logic for commercial devices — Use 32,000 logic elements and embedded RAM for custom control, data handling, and glue logic in commercial designs.
• Space-constrained boards — The 484-BBGA surface-mount package (23×23) supports compact PCB layouts where board space is limited.
• Low-voltage systems — Designed for systems operating within a 1.14 V to 1.26 V supply window for modern low-voltage architectures.

Unique Advantages

• High logic capacity: 32,000 logic elements provide substantial programmable resources for mid-range digital designs.
