Overview

The LFXP2-17E-5FTN256C is a non-volatile FPGA from Lattice Semiconductor's XP2 family, featuring 17,000 logic cells and 276KB of embedded RAM. Built on flexiFLASH architecture, it provides 'instant-on' capability and high security through 128-bit AES encryption and FlashBAK technology for integrated Flash and SRAM usage. This device eliminates the need for an external boot PROM, simplifying PCB layouts and enhancing design security.

Why Choose This Part

The primary advantage is the single-chip, non-volatile design which reduces board space and BOM cost by removing external configuration memory. It offers robust design security with Flash-based configuration and supports high-speed I/O standards including LVDS and DDR2 at clock speeds up to 420 MHz.

Applications

System Control and Sequencing
Utilizing instant-on capability to manage power-up sequencing and system reset logic before other complex processors boot.
Secure Firmware Updates
Leveraging 128-bit AES encryption and TransFR technology to perform secure, in-field hardware updates without interrupting system operation.
Industrial Protocol Bridging
Implementing custom logic to bridge interfaces such as LVDS, PCI, and DDR2 memory in industrial automation controllers.
Digital Signal Processing
Executing high-speed arithmetic operations using dedicated Multiply and Accumulate (MAC) blocks for filtering and sensor data processing.

Getting Started

Designers should use the Lattice Diamond software suite for synthesis, mapping, and routing. Hardware evaluation can be performed using Lattice XP2 development boards, and programming is typically handled via the JTAG interface using the Lattice USB-PCN-85 programming cable.

Also Consider

Spartan-7 S25 AMD (Xilinx) - Provides higher performance and more advanced fabric logic, though it requires an external configuration memory.
