LFSC3GA15E-5F256C

The LFSC3GA15E-5F256C is a commercial-grade SC-family field programmable gate array (FPGA) from Lattice Semiconductor designed for high-density logic and memory-centric embedded designs. It combines 15,000 logic elements with a large on-chip RAM budget and a 139-pin I/O footprint in a 256-ball BGA package for compact, surface-mount integration.

This device is well suited for communication and embedded-system applications that demand substantial logic resources, significant embedded memory, and flexible I/O connectivity while operating within standard commercial temperature and voltage ranges.

Key Features

• Logic Capacity — 15,000 logic elements suitable for medium-complexity FPGA designs and control logic integration.
• Embedded Memory — Approximately 1.05 Mbits of total on-chip RAM (1,054,720 bits) to support data buffering, FIFOs and memory-intensive functions.
• I/O Density — 139 I/Os providing broad external interfacing capability for peripherals, sensors and high-pin-count buses.
• Package & Mounting — 256-BGA (256-FPBGA, 17×17) surface-mount package for high pin-count routing in a compact footprint.
• Power Supply — Core operating voltage range from 0.95 V to 1.26 V to match modern low-voltage system rails.
• Operating Range & Grade — Commercial grade with an operating temperature range of 0 °C to 85 °C.
• RoHS Compliance — Environmentally compliant manufacturing.
• Family-Level Fabric & I/O Capabilities — The Lattice SC family includes a high-performance LUT4-based fabric, high-speed SERDES options, advanced programmable I/O standards (including differential and memory interfaces), and sysMEM block RAM architectures as documented in the SC/M family data sheet.
• Clocking & Timing (Family) — Family-level clocking options include analog PLLs and DLLs and high-frequency global and edge clocks to support demanding timing needs.

Typical Applications

• Network & Communications Equipment — Implement protocol bridging, packet processing logic, or SERDES-based serial links using the SC family’s communication-focused features.
• Embedded Systems & Controllers — Integrate complex control logic and on-chip memory for real-time embedded applications.
• Memory-Intensive Data Paths — Use the approximate 1.05 Mbits of embedded RAM for buffering, FIFO management and data re-timing in streaming applications.
• High-Density I/O Interfaces — Leverage 139 I/Os in a 256-BGA package for systems requiring many external connections in a compact board area.

Unique Advantages

• Balanced Logic and Memory — A combination of 15,000 logic elements and ~1.05 Mbits of on-chip RAM enables integrated implementations of complex logic plus sizable data buffering without external memory.
• Compact, High-Pin Count Package — 256-BGA (17×17) provides a high I/O count in a space-efficient surface-mount package for dense PCB designs.
• Low-Voltage Core Support — 0.95–1.26 V supply range aligns with modern, low-voltage system architectures to simplify power integration.
• Commercial Temperature Rating — Rated 0 °C to 85 °C for a wide range of standard consumer and industrial-adjacent applications.
• Standards-Focused Family Features — The SC family includes SERDES, programmable I/O standards and sysMEM block RAM capabilities that help address communication and memory-heavy design requirements.
• RoHS Compliant — Environmentally compliant manufacturing supports regulatory and sustainability needs.
