LFE2-20E-7F484C

The LFE2-20E-7F484C is an ECP2 family Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation designed for commercial-grade, surface-mount applications. It delivers a mid-range combination of programmable logic, I/O capacity and embedded memory suitable for designs that require up to 21,000 logic elements and extensive I/O connectivity.

This device targets projects that need balanced on-chip resources—approximately 0.283 Mbits of embedded RAM and 331 I/O—in a compact 484‑BBGA (484‑FPBGA, 23×23 mm) package while operating across a standard commercial temperature and low core-voltage window.

Key Features

• Logic Capacity  21,000 logic elements and 2,625 logic blocks (as provided) enable implementation of moderate-density digital designs and glue logic.
• Embedded Memory  Approximately 0.283 Mbits (282,624 bits) of on-chip RAM for buffering, FIFOs and small data storage functions.
• I/O Density  331 general-purpose I/O pins to support multiple interfaces, external peripherals, and board-level connectivity.
• Power  Core voltage operation from 1.14 V to 1.26 V to match system power-rail requirements for low-voltage FPGA designs.
• Package & Mounting  484‑BBGA (supplier package: 484‑FPBGA, 23×23 mm) in a surface-mount form factor for compact PCB integration.
• Operating Range  Commercial-grade operating temperature from 0 °C to 85 °C to match typical consumer and commercial embedded environments.
• Compliance  RoHS compliant to support lead-free assembly and regulatory requirements.

Typical Applications

• Embedded system prototyping  Use the device for developing and validating mid-density programmable designs that require flexible logic and embedded RAM.
• I/O‑intensive control and glue logic  Leverage 331 I/O pins to implement board-level interfacing, protocol bridging, and peripheral management.
• Signal buffering and small data storage  Take advantage of the embedded RAM for FIFOs, buffering, and short-term data retention in data-paths.
• Compact board-level FPGA integration  The 484‑BBGA surface-mount package enables high-density placement in space-constrained designs.

Unique Advantages

• Balanced logic and I/O capacity: 21,000 logic elements paired with 331 I/O provide a practical balance for many mid-range FPGA tasks without overspecifying.
• Integrated memory for data-paths: Approximately 0.283 Mbits of embedded RAM reduces the need for external memory in buffering and small storage roles.
• Compact, manufacturable package: 484‑BBGA (484‑FPBGA, 23×23 mm) surface-mount package supports compact PCB layouts and standard assembly processes.
• Low core-voltage operation: 1.14 V to 1.26 V core supply supports low-voltage system architectures and power-sensitive designs.
• Commercial temperature suitability: Rated for 0 °C to 85 °C operation to meet the needs of consumer and commercial electronics projects.
• RoHS compliant: Enables lead-free production and aligns with common environmental regulations.
