• Advanced I/O standards and timing — The family supports a broad set of electrical standards and high-performance I/O timing features (PURESPEED I/O, programmable input delay and dynamic alignment) as documented for Lattice SC devices.
• Supply voltage — Operates from 0.95 V to 1.26 V, enabling low-voltage system designs.
• Industrial temperature range — Rated for −40 °C to 105 °C for operation in harsh environments.
• Package and assembly — 1020-BBGA FCBGA package (Supplier Device Package: 1020-OFcBGA Rev 2, 33×33) optimized for surface-mount assembly and high pin count designs.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial control and automation — Large logic capacity and industrial temperature rating enable implementation of motion control, PLC offloads and protocol bridging in factory environments.
• Communications and networking — High I/O count and family-level SERDES/IP support are suited for packet processing, line cards and interface aggregation tasks that need high throughput and flexible I/O.
• Memory‑intensive embedded systems — Approximately 4.08 Mbits of on-chip RAM supports large FIFOs, buffering, and real-time data processing in embedded appliances and instrumentation.
• High-density board designs — The 1020-BBGA package and 562 I/Os provide the pin count and routing density required for multi‑interface mezzanine or mainboard designs.

Unique Advantages

• Substantial logic and memory in one device: Combining ~40,000 logic elements with ~4.08 Mbits of embedded RAM reduces the need for external FPGA/DRAM combinations and simplifies system architecture.
• High I/O count for flexible integration: 562 I/Os let you consolidate interfaces and sensors directly to the FPGA, reducing external glue logic and board complexity.
• Industrial-ready thermal performance: −40 °C to 105 °C operating range provides design headroom for industrial deployments and extended-temperature systems.
• Low-voltage operation: 0.95 V–1.26 V supply range supports modern low-power systems and helps align with low-voltage core power domains.
• High-density package: 1020-BBGA (33×33) package delivers a compact, high-pin-count solution for space-constrained, high-functionality boards.
• Standards-backed family features: The Lattice SC/M family architecture documented in the datasheet includes SERDES, advanced I/O control and sysMEM capabilities that accelerate implementation of common communications and memory-intensive functions.
