LFE3-35EA-8LFN484C

The LFE3-35EA-8LFN484C is an ECP3 Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation. It provides a balance of programmable logic, embedded memory and a high I/O count in a compact ball-grid array package.

This device is suited to designs that require sizable logic capacity, on-chip memory, and extensive I/O in a surface-mount 484-BBGA footprint, delivering a commercial-grade FPGA solution for a range of embedded and system-level implementations.

Key Features

• Logic Resources  4125 CLBs providing 33,000 logic elements to implement custom digital logic and control functions.
• Embedded Memory  Approximately 1.36 Mbits of embedded memory (1,358,848 total RAM bits) for buffering, state storage and local data processing.
• I/O Density  295 user I/O pins to support wide parallel interfaces, bus connections and mixed-signal front-end routing.
• Power Supply  Core supply range from 1.14 V to 1.26 V for the device core domain.
• Package & Mounting  484-BBGA package (supplier device package: 484-FPBGA, 23×23) designed for surface-mount assembly in compact board layouts.
• Operating Range  Commercial-grade operating temperature from 0 °C to 85 °C.
• RoHS Compliance  Device is RoHS compliant.

Typical Applications

• Custom logic acceleration  Implement application-specific datapaths and control logic using the device’s 33,000 logic elements and CLB resources.
• High-density I/O systems  Leverage 295 I/O pins for multi-channel interfaces, bus bridging or peripheral aggregation.
• On-chip buffering and state machines  Use approximately 1.36 Mbits of embedded memory for buffering, FIFOs and local state storage.
• Compact embedded designs  The 484-BBGA (23×23) package and surface-mount form factor suit space-constrained PCBs.

Unique Advantages

• Substantial logic capacity: 33,000 logic elements enable implementation of complex custom logic without immediate external components.
• Significant on-chip memory: Approximately 1.36 Mbits of RAM reduces reliance on external memory for many buffering and stateful functions.
• High I/O count: 295 I/O pins accommodate broad peripheral connectivity and parallel interfacing requirements.
• Compact packaging: 484-BBGA / 484-FPBGA (23×23) package supports dense PCB integration while maintaining large resource counts.
• Commercial temperature rating: 0 °C to 85 °C offers suitability for standard commercial environments.
• Regulatory readiness: RoHS compliance helps meet environmental requirements for modern product designs.
