Key Features

• Logic Capacity — Approximately 19,000 logic elements for implementing mid-range digital logic and control functions.
• Embedded Memory — Approximately 1.25 Mbits of on-chip RAM (1,246,208 bits) for data buffering, FIFOs and tightly coupled storage.
• I/O Resources — 304 user I/Os to support dense interfacing with peripherals, memories and mezzanine connectors.
• Package & Mounting — 484-ball fpBGA (23 × 23 mm) package, surface-mount mounting for compact board-level integration.
• Power — Core supply range 1.14 V to 1.26 V to match system power rails and regulators.
• Industrial Temperature Grade — Specified operating range from −40 °C to 100 °C for deployment in industrial environments.
• Family-Level System Features — As a member of the LatticeECP2/M family, benefits include embedded sysDSP blocks, high-speed SERDES capability and flexible sysI/O buffer support (family-level capabilities described in the LatticeECP2/M datasheet).
• Compliance — RoHS compliant for environmental and assembly considerations.

Typical Applications

• Industrial Control — Implement motor control logic, deterministic I/O handling and protocol bridging in factory automation systems using the device’s I/O density and industrial temperature rating.
• Communications & Networking — Use the part for mid-range packet processing, protocol adaptation and interface aggregation where on-chip RAM and logic capacity handle buffering and protocol logic.
• Video & Imaging — Deploy for frame buffering, data formatting and pre/post-processing functions that leverage the device’s embedded RAM and DSP-oriented family features.
• Custom Peripherals & Interfaces — Rapidly implement custom bus masters, sensor interfaces and glue logic using its 304 I/Os and flexible package options.

Unique Advantages

• Balanced Integration: Combines ~19,000 logic elements with ~1.25 Mbits of embedded RAM to centralize control and buffering on a single device, reducing board-level BOM.
• High I/O Count in Compact Package: 304 I/Os in a 23 × 23 mm 484-ball fpBGA provide dense connectivity while keeping PCB footprint small.
• Industrial Reliability: Specified for −40 °C to 100 °C operation, suitable for extended-temperature embedded systems.
• Power Compatibility: Narrow core supply range (1.14 V–1.26 V) simplifies power-supply design for systems using optimized core rails.
• Family Ecosystem: Access to Lattice ECP2/M family features—such as enhanced DSP blocks, SERDES and flexible I/O standards—enables scalable designs and easier reuse across product variants.
