LFE3-70EA-8FN484C

The LFE3-70EA-8FN484C from Lattice Semiconductor is an ECP3-series FPGA in a 484-ball fine-pitch BGA package designed for mid-range system integration. It delivers 67,000 logic elements, approximately 4.53 Mbits of embedded memory, and up to 295 user I/Os for applications requiring a balanced mix of logic density, on-chip memory and high-speed I/O.

Targeted at communications, video/broadcast and high-performance embedded applications, this commercial-grade device combines the ECP3 family’s DSP, SERDES and flexible I/O capabilities with a 1.14 V to 1.26 V core supply and a 0 °C to 85 °C operating range.

Key Features

• Core Logic  67,000 logic elements provide substantial programmable logic capacity for mid-density designs.
• On‑Chip Memory  Total RAM bits: 4,526,080 (approximately 4.53 Mbits) to support embedded buffers, FIFOs and data storage.
• I/O and SerDes  295 user I/Os and ECP3-family embedded SERDES channels (family supports multi-gigabit SERDES up to 3.2 Gbps) for high-speed serial and parallel interfaces.
• sysDSP and Arithmetic  ECP3 family sysDSP architecture provides optimized slices for multiply-accumulate and high-performance DSP functions (family-level feature).
• Clocking and PLLs/DLLs  ECP3 family supports multiple PLLs and DLLs for flexible clocking (ECP3-70 family-level provision of up to 10 PLLs and 2 DLLs).
• Package and Mounting  484-FPBGA (23 × 23 mm) package, surface-mount mounting for compact board designs.
• Power  Core voltage supply range 1.14 V to 1.26 V; family specifies a 1.2 V core power supply.
• Commercial Grade and Temperature  Grade: Commercial; operating temperature range 0 °C to 85 °C.
• Compliance  RoHS compliant for environmental and manufacturing requirements.

Typical Applications

• High‑Speed Networking & Communications  Implement protocol engines and SERDES-based links such as Ethernet, PCIe and other serial interfaces supported by the ECP3 family.
• Video and Broadcast Processing  Use the device’s DSP capabilities and abundant I/O to handle SMPTE/serial video interfaces and real‑time processing pipelines.
• Embedded Processing and Control  Deploy as a system controller or custom peripheral offload in embedded platforms requiring moderate logic density and on‑chip memory.
• Custom High‑Speed Interfaces  Leverage the 295 I/Os and family SERDES to implement custom data converters, high‑speed ADC/DAC interfaces or multi-channel serial links.

Unique Advantages

• Balanced Logic and Memory:  67,000 logic elements combined with approximately 4.53 Mbits of embedded memory enable complex control, buffering and processing on a single device.
• High I/O Count:  295 user I/Os allow dense parallel interfaces and flexible pin assignments to match diverse board-level requirements.
• Family-Level High‑Speed SerDes:  ECP3 family SERDES support multi‑gigabit serial links (up to 3.2 Gbps family-level), enabling integration of modern high‑speed serial protocols.
• Flexible Clocking and DSP:  Family features such as multiple PLLs/DLLs and sysDSP slices simplify implementation of signal processing and precise clock domains.
• Compact Package:  484‑ball FPBGA (23 × 23 mm) provides a compact form factor for space-constrained designs while delivering a high pin count.
• Commercial Availability and Compliance:  Commercial-grade temperature range and RoHS compliance support standard production requirements.
