Lattice LFXP2-17E-5FN484C: A Comprehensive Technical Overview of the Low-Power FPGA

In the realm of programmable logic, the demand for devices that balance performance with minimal power consumption is ever-increasing. The Lattice LFXP2-17E-5FN484C stands as a prime example, engineered specifically for power-sensitive applications. As a member of Lattice Semiconductor's LatticeXP2™ family, this FPGA leverages a non-volatile technology foundation to deliver a unique blend of instant-on capability, high integration, and remarkably low static power.

At the core of this device is its innovative non-volatile, flash-based architecture. Unlike SRAM-based FPGAs that require an external boot PROM, the LFXP2-17E-5FN484C stores its configuration data directly on-chip. This eliminates the configuration bitstream overhead during power-up, enabling a true "Instant-On" operation critical for system control and management functions. Furthermore, this architecture is inherently secure, as the configuration cannot be read back, offering robust protection against intellectual property (IP) theft.

The device's identifier, "LFXP2-17E-5FN484C," provides a detailed breakdown of its capabilities:

LFXP2: Denotes the LatticeXP2 family.

17E: Indicates a logic density of approximately 17,000 Look-Up Tables (LUTs), providing ample resources for complex logic implementation.

5: Represents a performance grade, often related to speed and timing.

FN484: Specifies the 484-pin Fine-Pitch Ball Grid Array (FPBGA) package. This package type is designed for high-density PCB designs.

C: Typically indicates a commercial temperature range (0°C to +85°C).

The LFXP2-17E is architected for low power consumption. Its flash cell configuration draws extremely low static current (ICC), often in the microamp (µA) range, making it ideal for battery-operated or always-on applications. The programmable sysI/O buffers support a wide range of voltages, including LVCMOS, LVTTL, and SSTL, allowing for seamless interface with other components in a mixed-voltage system while optimizing power for each I/O bank.

Beyond the core logic, this FPGA is rich in embedded memory and pre-engineered blocks. It features 88 kbits of embedded block RAM (EBR) and 64 kbits of distributed RAM, facilitating efficient data buffering and storage. For arithmetic-intensive tasks, it incorporates dedicated sysDSP™ slices, which accelerate complex mathematical operations like multiplication and filtering without consuming general-purpose logic resources.

A key strength of the LatticeXP2 platform is its transparent field reconfigurability. Designers can implement two distinct functions on a single chip and dynamically switch between them without a full power cycle, enhancing system flexibility. Combined with its live-update capability, it allows for in-field firmware upgrades, ensuring long-term product viability.

ICGOOODFIND: The Lattice LFXP2-17E-5FN484C is a highly integrated, secure, and power-optimized FPGA solution. Its flash-based technology delivers instant-on performance and eliminates the boot PROM, making it a superior choice for a wide array of applications, including power management, portable medical devices, telecommunications infrastructure, industrial automation, and consumer electronics where reliability, low power, and space savings are paramount.
