LFXP2-5E-5TN144I

The LFXP2-5E-5TN144I is a flash-based LatticeXP2 family FPGA from Lattice Semiconductor Corporation combining non-volatile configuration with a LUT-based fabric. The device provides approximately 5,000 logic elements, about 166 Kbits of embedded RAM, and 100 I/O in a 144‑pin LQFP surface-mount package for compact, industrial applications.

Designed for applications that require instant-on configuration, secure updates and low-voltage operation, the device delivers flexible I/O, DSP resources and on-chip memory while supporting industrial temperature operation from -40°C to 100°C.

Key Features

• flexiFLASH architecture  Flash-based configuration with instant-on and infinitely reconfigurable single-chip implementation as described for the LatticeXP2 family.
• Secure Live Update  Live Update technology with TransFR and support for 128-bit AES encryption for secure dual-boot and update scenarios (family-level feature).
• Logic and DSP resources  Approximately 5,000 logic elements and three sysDSP blocks with 12 × 18×18 multipliers (family device values for XP2-5) to accelerate multiply–accumulate workloads.
• On-chip memory  Total RAM bits: 169,984 (approximately 166 Kbits of embedded SRAM) plus distributed RAM as provided by the LatticeXP2 XP2-5 device class.
• Flexible I/O  100 user I/O in the 144‑pin LQFP package with LatticeXP2 family support for a broad range of I/O standards and source-synchronous interfaces.
• Clocking  On-chip PLL resources consistent with the XP2-5 device class (device table indicates 2 PLLs) for clock multiplication, division and phase shifting.
• Low-voltage operation  Voltage supply range: 1.14 V to 1.26 V, matching 1.2 V family supply requirements for the XP2 series.
• Industrial temperature  Rated for operation from -40°C to 100°C for reliable performance in industrial environments.
• Package and mounting  144‑pin LQFP (supplier package: 144‑TQFP, 20 × 20 mm), surface-mount mounting for space-efficient PCB designs.

Typical Applications

• Industrial control and automation  Industrial-rated temperature range and low-voltage operation make the device suitable for embedded control, I/O aggregation and real-time logic functions in factory and process equipment.
• High-performance signal processing  sysDSP blocks and multiple 18×18 multipliers support multiply–accumulate tasks useful for filtering, encoding and other DSP workloads.
• Secure firmware updates and system management  Flash-based flexiFLASH configuration with Live Update and AES-128 support enables secure, dual-boot update strategies for fielded products.
• Compact board-level designs  100 I/O in a 144‑pin LQFP surface-mount package provides a balance of I/O density and footprint for space-constrained embedded systems.

Unique Advantages

• Instant-on non-volatile configuration: Flash-based flexiFLASH enables immediate device initialization without external configuration RAM or large boot sequences.
• Integrated DSP capability: sysDSP blocks and dedicated multipliers reduce the need for external accelerators for arithmetic-intensive functions.
• Secure, field-updatable architecture: Live Update with TransFR and AES-128 encryption supports secure image management and in-field updates.
• Industrial robustness: Rated for -40°C to 100°C operation and surface-mount packaging suitable for industrial environments.
• Balanced integration: Combines logic, embedded RAM and flexible I/O in a single 144‑pin package to simplify PCB BOM and layout.
