• Embedded Memory — Approximately 4.64 Mbits of on-chip RAM (total RAM bits: 4,642,816) for buffering, FIFOs and local data storage.
• I/O Resources — 416 user I/Os, supporting a wide range of system interfaces and dense board-level connectivity.
• SERDES (family-level) — LatticeECP2M family supports embedded SERDES with data rates from 250 Mbps to 3.125 Gbps and up to 16 channels for high-speed serial protocols.
• sysDSP and Multiplier Support (family-level) — Family sysDSP blocks support high-performance multiply/accumulate operations with multiplier configurations up to 36×36 per block.
• Clocking and Timing — Family includes GPLLs and SPLLs and DLLs for clock multiplication, division and phase/delay adjustment.
• Programmable sysI/O — Family-level support for a broad set of I/O standards including LVCMOS/LVTTL, LVDS and multiple SSTL/HSTL options to interface with memory, ADCs/DACs and standard buses.
• Configuration and System Features — Supports 1149.1 boundary-scan, SPI boot flash interface, dual boot images and embedded system-level utilities referenced at the family level.
• Power and Operating Range — Core supply: 1.14 V to 1.26 V; Industrial operating temperature: −40 °C to 100 °C.
• Package and Mounting — 900-ball FBGA (900-FPBGA, 31 × 31 mm), surface-mount; RoHS compliant.

Typical Applications

• High-speed Communications — Implement PHY/PCS and protocol bridging using embedded SERDES (family capabilities) and abundant I/Os for interfaces such as Ethernet and serial links.
• Embedded Processing and Control — Use the device’s 67,000 logic elements and on-chip RAM for protocol offload, control engines and custom state machines.
• Data Acquisition and Conversion — Interface with high-speed ADCs/DACs using programmable sysI/O and on-chip DSP resources (family-level) for real-time preprocessing.
• Memory Interfacing and Buffering — Leverage the device’s RAM and dedicated DDR support (family-level) for local buffering, packet assembly and frame storage.

Unique Advantages

• High Integration Density: Approximately 67,000 logic elements plus ~4.64 Mbits of embedded memory reduce external component count and simplify board-level design.
• Large I/O Footprint: 416 I/Os provide flexibility to connect multiple peripherals, memory interfaces and high-speed links without external multiplexing.
• Industrial Operating Range: −40 °C to 100 °C rating supports use in industrial and harsh-environment applications.
• Compact, Surface-Mount Package: 900-ball FBGA (31 × 31 mm) enables a dense PCB layout while supporting a high pin count.
• Low-Voltage Core: Narrow core supply window (1.14 V to 1.26 V) supports stable, power-efficient operation in designs optimized for modern FPGA fabrics.
• RoHS Compliant: Meets standard environmental compliance for modern electronic assemblies.
