• Embedded Memory  Total on-chip memory of 906,240 bits (approximately 0.91 Mbits) to support buffers, state machines and embedded data storage.
• sysDSP and Multipliers  Built-in sysDSP blocks and dedicated multipliers for high-performance multiply-accumulate operations; XP2-40 devices include multiple sysDSP blocks and 18×18 multiplier resources as part of the LatticeXP2 family architecture.
• Flexible I/O  Up to 363 user I/Os on the 484-ball fpBGA (23 × 23 mm) package, supporting a wide range of standards for interface connectivity.
• flexiFLASH Configuration  Flash-based configuration with instant-on behavior, on-chip FlashBAK memory and Serial TAG memory for secure, reconfigurable single-chip solutions.
• Live Update and Security  Live Update technology with TransFR and support for secure updates (128-bit AES encryption) and dual-boot image capability as described for the LatticeXP2 family.
• Clocking  Multiple analog PLLs (sysCLOCK) to enable clock multiplication, division and phase shifting for system timing flexibility.
• High-speed Interface Support  Pre-engineered interfaces include DDR/DDR2 memory interfaces up to 200 MHz, 7:1 LVDS display interfaces and XGMII for high-speed communications as provided by the family architecture.
• Package and Mounting  484-FPBGA (23 × 23 mm) surface-mount package for dense board integration and up to 363 available I/Os.
• Industrial Temperature Range  Rated for operation from -40°C to 100°C for use in industrial environments.

Typical Applications

• Industrial Control and Automation  Use the device for real-time control, protocol bridging and I/O aggregation where industrial temperature operation and robust I/O counts are required.
• Embedded Signal Processing  Leverage sysDSP blocks and dedicated multipliers for filtering, sensor fusion and other multiply-accumulate tasks inside compact FPGA-based processing subsystems.
• Memory and Interface Controllers  Implement DDR/DDR2 memory controllers, bus bridges and high-speed interface logic using the device’s on-chip memory and pre-engineered interface support.
• Display and Video Interfaces  Drive LVDS-based display interfaces and other source-synchronous links using the LatticeXP2 family’s pre-engineered 7:1 LVDS support and flexible I/O buffers.
• High-speed Communications  Support packet processing and protocol termination using XGMII-capable interfaces and abundant I/O resources for board-level connectivity.

Unique Advantages

• Flash-based Instant-On:  flexiFLASH configuration enables immediate startup without external configuration memory, simplifying system boot sequences.
• Integrated DSP Resources:  sysDSP blocks and dedicated multipliers reduce the need for external DSP chips for common signal processing tasks.
• High I/O Density in a Compact Package:  363 I/Os in a 484-ball fpBGA (23 × 23 mm) provide extensive external connectivity while minimizing PCB area.
• Secure Field Updates:  Live Update features with secure update options (128-bit AES) and dual-boot support help manage remote firmware revisions and rollback strategies.
• Industrial Reliability:  Rated operation from -40°C to 100°C supports deployment in demanding industrial environments.
• Design Ecosystem:  Part of the LatticeXP2 family with available design tools and IP enabling migration and reuse across device densities.
