LFE2-12E-6FN484C

The LFE2-12E-6FN484C is a commercial-grade Field Programmable Gate Array (FPGA) from Lattice Semiconductor's ECP2 family. It delivers a medium-density programmable fabric with 12,000 logic elements and 226,304 bits of embedded RAM for implementing custom digital logic and buffering on-chip.

Designed as a surface-mount device in a 484-FPBGA (23 × 23) package, the device supports up to 297 I/O and operates from 1.14 V to 1.26 V over a 0 °C to 85 °C temperature range, making it suitable for a wide range of standard commercial embedded designs.

Key Features

• Core Logic 12,000 logic elements provide a medium-density programmable fabric for implementing custom logic, state machines, and protocol handling.
• Embedded Memory 226,304 bits of on-chip RAM (approximately 0.226 Mbits) for local buffering, FIFOs, and small data storage without external memory.
• I/O Density Up to 297 I/O pins enable extensive interfacing options for peripheral devices and multiple signal domains.
• Package & Mounting 484-FPBGA (23 × 23) package in a 484-BBGA footprint, supplied as a surface-mount device for compact board integration.
• Power Narrow core supply range of 1.14 V to 1.26 V for the programmable core.
• Operating Range Commercial operating temperature range from 0 °C to 85 °C.
• Compliance RoHS compliant, supporting lead-free manufacturing requirements.

Typical Applications

• Custom logic implementation — Use the 12,000 logic elements to implement application-specific datapaths, control logic, and protocol engines on-chip.
• Interface bridging and I/O expansion — The 297 I/O pins support building multi-interface gateways, protocol translators, or expanding MCU/processor connectivity.
• On-chip buffering and small-data storage — 226,304 bits of embedded RAM provide local buffering for streaming data, FIFOs, and temporary storage without external memory.
• Compact board designs — The 484-FPBGA package and surface-mount mounting simplify integration where board area and assembly compatibility are important.

Unique Advantages

• Balanced logic and memory capacity: 12,000 logic elements combined with 226,304 bits of RAM allow designers to implement both control logic and local data buffering on a single device, reducing external components.
• High I/O count: 297 I/O pins enable complex system interfacing and multi‑channel connectivity without adding external I/O expanders.
• Compact, manufacturable package: 484-FPBGA (23 × 23) surface-mount package supports compact PCB layouts and standard assembly processes.
• Controlled supply and operating range: Defined core voltage range (1.14 V–1.26 V) and commercial temperature rating (0 °C–85 °C) simplify power supply and thermal planning for commercial systems.
• RoHS compliant: Supports lead‑free manufacturing flows and regulatory requirements for commercial electronics.
