LFXP2-5E-5QN208I

The LFXP2-5E-5QN208I is a LatticeXP2 family field programmable gate array (FPGA) offered in a 208‑pin BFQFP package. It combines a LUT-based FPGA fabric with non-volatile flash configuration (flexiFLASH architecture) to deliver instant-on, reconfigurable logic for mid-density embedded designs.

With 5,000 logic elements, approximately 169,984 bits of on-chip memory, 146 user I/Os and industrial temperature rating, this device targets applications that require reconfigurable logic, embedded memory and DSP acceleration in a compact surface-mount package.

Key Features

• Core Logic — 5,000 logic elements (LUT-based FPGA fabric) suitable for mid-density logic integration and glue logic.
• Non‑volatile Configuration (flexiFLASH) — Flash-based architecture provides instant-on and infinitely reconfigurable single-chip configuration with on-chip flash storage.
• Embedded Memory — Approximately 169,984 bits of on-chip RAM for embedded storage and buffering needs.
• sysDSP and Multipliers — Family-level sysDSP blocks (XP2-5 family includes three sysDSP blocks) with dedicated 18×18 multipliers for efficient MAC and signal-processing tasks.
• Flexible I/O — 146 user I/Os available in the 208-pin package for interfaces, bus bridging and peripheral connectivity.
• Power and Voltage — Designed to operate at a core supply in the range of 1.14 V to 1.26 V (nominal 1.2 V operation referenced in family data).
• Package and Mounting — 208‑pin BFQFP surface-mount package (supplier device package listed as 208‑PQFP, 28×28 mm) to support compact board layouts.
• Industrial Temperature Range — Rated for operation from −40 °C to 100 °C for industrial applications.
• Standards and System Support — Family-level support includes on-chip PLLs, source-synchronous interfaces (DDR/DDR2 support up to 200 MHz) and tools/IP support from the Lattice ecosystem as documented in the family datasheet.
• Environmental — RoHS compliant.

Typical Applications

• Display and Video Interfaces — Source-synchronous and LVDS support in the XP2 family make this device suitable for display interface bridging and timing control.
• Memory Interface Logic — Use for DDR/DDR2 interface logic and timing adapters, leveraging pre-engineered source synchronous interfaces and on-chip PLLs.
• Embedded Signal Processing — sysDSP blocks and dedicated multipliers provide MAC capability for mid-range signal processing tasks and sensor data aggregation.
• Industrial Control and Automation — Industrial temperature rating and flexible I/O make the device appropriate for motor control, I/O consolidation and protocol bridging in industrial systems.

Unique Advantages

• Instant‑on, reconfigurable flash architecture — flexiFLASH enables single‑chip non-volatile configuration with instant startup and repeated reprogramming without external configuration PROMs.
• Balanced mid-range resources — 5,000 logic elements with approximately 170 Kbits of embedded memory provide a compact platform for designs that need both logic and on-chip storage.
• Integrated DSP capability — Dedicated sysDSP blocks and multiple fixed multipliers reduce the need for external DSP components in compute tasks.
• Broad I/O in a compact package — 146 user I/Os in a 208‑pin BFQFP enable dense connectivity while supporting surface-mount PCB assembly.
• Industrial temperature and RoHS compliance — Suitable for deployment in temperature-challenging environments while meeting RoHS environmental requirements.
• Supported design ecosystem — Family datasheet documents support for on-chip PLLs, source-synchronous interfaces and vendor design tools/IP to accelerate development.
