LFE2-50SE-5F484I

The LFE2-50SE-5F484I is an ECP2 family Field Programmable Gate Array (FPGA) provided in a 484-ball BGA package. It combines a substantial logic capacity with embedded RAM and a high I/O count, and is specified for industrial-grade operation.

This device is suited to designs that need on-chip programmable logic with support for many external interfaces, low-voltage operation, and an extended temperature range for industrial environments.

Key Features

• Logic Capacity  48,000 logic elements provide significant programmable logic resources for complex designs.
• Logic Blocks  6,000 logic blocks deliver structured resources for partitioning and implementing logic functions.
• Embedded Memory  Approximately 0.4 Mbits of on-chip RAM (396,288 bits) for data buffering, FIFOs, and small memory structures.
• I/O Density  339 I/O pins to support multiple external interfaces and parallel connections.
• Power  Operates from a core supply range of 1.14 V to 1.26 V for low-voltage core operation.
• Package & Mounting  484-ball FBGA package (484-BBGA / supplier package 484-FPBGA 23×23) in a surface-mount form factor for high-density board designs.
• Temperature Range & Grade  Industrial grade operation with an ambient range of −40 °C to 100 °C for demanding environments.
• Standards Compliance  RoHS compliant.

Typical Applications

• Industrial Control Systems  Industrial-grade temperature rating and extensive I/O make the device suitable for control logic, sensor aggregation, and factory automation interfaces.
• High-Density I/O Gateways  With 339 I/Os, the FPGA can consolidate multiple peripheral interfaces or bridge parallel data paths.
• Embedded Logic and Glue  48,000 logic elements and on-chip RAM support custom protocol handling, timing adaptation, and glue logic between subsystems.

Unique Advantages

• Substantial Logic Resource:  48,000 logic elements enable implementation of sizeable logic functions and parallel datapaths without external CPLDs.
• Compact High-Density Packaging:  484-ball FBGA (23×23) provides a small footprint for complex designs while accommodating many I/Os.
• Industrial Temperature Qualification:  Specified for −40 °C to 100 °C operation to meet the needs of temperature-challenging deployments.
• Integrated On-Chip Memory:  Approximately 0.4 Mbits of embedded RAM for buffering, state machines, and small data stores reduces dependence on external memory.
• Low-Voltage Core Operation:  Core supply range of 1.14 V to 1.26 V supports designs targeting modern low-voltage domains.
• RoHS Compliant:  Meets RoHS environmental requirements for lead-free manufacturing processes.
