LFXP2-5E-5QN208C

The LFXP2-5E-5QN208C is a commercial-grade XP2 series FPGA from Lattice Semiconductor that combines LUT-based programmable logic with non-volatile on-chip flash configuration (flexiFLASH) for instant-on and infinitely reconfigurable designs. With approximately 5,000 logic elements, roughly 170 Kbits of embedded RAM, dedicated DSP resources and flexible I/O in a 208-pin PQFP package, this device targets mid-density embedded and interface applications requiring compact, low-voltage FPGA logic.

Key Features

• Core Logic: Approximately 5,000 logic elements for implementing control logic, glue logic and moderate-density processing functions.
• Memory: Approximately 169,984 bits (≈170 Kbits) of on-chip embedded RAM and family support for distributed RAM to store buffers, look-up tables and small data structures.
• sysDSP Blocks & Multipliers: XP2-5 family implementation includes three sysDSP blocks and twelve 18×18 multipliers for MAC and signal-processing tasks.
• Clocking: Two analog PLLs (GPLLs) for clock multiply/divide and phase-shift functions to support synchronous interfaces and timing domains.
• Configuration & Security: flexiFLASH architecture with instant-on, FlashBAK embedded block memory, serial TAG memory, and Live Update features including TransFR and 128-bit AES encryption; supports dual-boot with external SPI.
• Flexible I/O: 146 user I/Os in the 208-BFQFP package; family-level I/O buffer support includes LVCMOS, LVTTL, SSTL, HSTL, LVDS and other standards for diverse interface requirements.
• Power & Temperature: Low-voltage operation with a stated supply range of 1.14 V to 1.26 V and a commercial operating temperature range of 0 °C to 85 °C.
• Package & Mounting: Surface-mount 208-pin PQFP (28 × 28 mm) package for compact board-level integration.
• Compliance: RoHS compliant.

Typical Applications

• Display and Video Interfaces — Source-synchronous and multi-lane LVDS support and on-chip PLLs make the device suitable for display timing, serialization and interface bridging.
• Memory and Bus Interfaces — Pre-engineered DDR/DDR2 interface support and flexible I/O allow use as a protocol bridge or memory controller front-end in embedded systems.
• Embedded Signal Processing — sysDSP blocks and 18×18 multipliers enable on-device multiply-accumulate operations for sensor processing, filter blocks and real-time data handling.
• Connectivity and Peripheral Control — A dense set of I/Os in a compact PQFP package is well-suited for managing peripherals, interface translation and protocol glue logic in consumer and communications equipment.

Unique Advantages

• Instant-on non-volatile architecture: flexiFLASH enables immediate availability of FPGA logic at power-up without external configuration storage.
• Integrated DSP resources: sysDSP blocks and 18×18 multipliers reduce the need for external accelerators when implementing signal-processing functions.
• Secure, flexible updates: Live Update with TransFR and 128-bit AES encryption supports secure field updates and dual-boot strategies for robust firmware management.
• Low-voltage operation: Designed for ~1.2 V supply operation which helps with power budgeting in modern low-voltage systems.
• Compact package with generous I/O: 146 I/Os in a 208-PQFP (28 × 28 mm) provides a balance of board-level density and accessibility for routing and testing.
