LFE2-20E-5Q208I

The LFE2-20E-5Q208I is an ECP2 Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation. It provides approximately 21,000 logic elements, roughly 282,624 bits of on-chip RAM (about 0.28 Mbits), and up to 131 user I/Os in a 208-BFQFP surface-mount package.

With a core supply range of 1.14 V to 1.26 V and an industrial operating temperature range of −40°C to 100°C, this device is specified for applications that require programmable logic capacity, on-chip memory, and a moderate number of general-purpose I/Os in a 208-pin PQFP footprint.

Key Features

• Logic Capacity  Approximately 21,000 logic elements to implement custom digital functions and mid-sized FPGA designs.
• Embedded Memory  Approximately 282,624 bits (≈0.28 Mbits) of on-chip RAM for buffering, state machines, and small data storage.
• I/O Resources  Up to 131 general-purpose I/Os to support multiple parallel interfaces and peripheral connections.
• Core Power  Narrow core voltage supply range of 1.14 V to 1.26 V for predictable power domain design.
• Package & Mounting  208-BFQFP package (supplier device package: 208-PQFP, 28 × 28) in a surface-mount form factor for board-level integration.
• Industrial Temperature Range  Specified to operate from −40°C to 100°C for industrial environments.
• Regulatory Compliance  RoHS compliant.

Typical Applications

• Programmable control and interface logic  Implements custom control functions and I/O aggregation where up to 131 user I/Os and mid-level logic density are required.
• Data buffering and small memory tasks  Uses the on-chip RAM for buffering, FIFOs, and small embedded storage in streaming or packetized data paths.
• Prototype and board-level integration  Surface-mount 208-pin PQFP package simplifies replacement of discrete glue-logic with a programmable solution during development cycles.

Unique Advantages

• Balanced logic and memory  Combines roughly 21,000 logic elements with approximately 0.28 Mbits of embedded RAM to handle control logic and modest data storage without external memory.
• Ample I/O count  131 I/Os support multiple peripheral connections and parallel interfaces without immediate need for external I/O expanders.
• Industrial temperature support  Rated for −40°C to 100°C operation, allowing deployment in a wide range of industrial environments.
• Compact package  208-BFQFP / 208-PQFP (28 × 28) surface-mount package offers a compact footprint suitable for dense board layouts.
• Regulatory assurance  RoHS compliance supports environmentally conscious designs and supply-chain requirements.
