Lattice LC4128V-75TN128C: Key Features, Architecture, and Target Applications

The Lattice LC4128V-75TN128C is a prominent member of the high-performance, low-power LatticeXP2 family of non-volatile FPGAs. This specific device balances capacity, power efficiency, and cost, making it a versatile solution for a wide array of embedded system designs. It is particularly engineered for applications where instant startup, design security, and low power consumption are critical.

Key Features

This FPGA is distinguished by several compelling features. It boasts 1280 Look-Up Tables (LUTs) alongside other essential logic elements, providing a solid logic capacity for complex control functions. A standout attribute is its non-volatile, flash-based technology. This allows the device to be instantly active upon power-up, eliminating the need for an external boot PROM and simplifying board design. Furthermore, this technology offers inherent resistance to unauthorized readback, securing intellectual property. The device also supports TransFR (Transparent Field Reconfiguration) technology for in-field updates with minimal system interruption. Its low static power consumption makes it ideal for power-sensitive designs. The -75 speed grade ensures reliable performance for a broad range of applications.

Architecture

The architecture of the LC4128V-75TN128C is optimized for efficient logic integration. The core is built around a sea of programmable logic blocks, each containing the fundamental 4-input LUTs and flip-flops. These blocks are interconnected by a high-performance, low-skew routing matrix. Beyond the generic fabric, the FPGA incorporates dedicated blocks to enhance functionality and save logic resources. It features embedded block RAM (EBR) for data storage, distributed RAM, and Phase-Locked Loops (PLLs) for advanced clock management. Housed in a compact 128-pin Thin Quad Flat Pack (TQFP) package, it offers a considerable number of user I/Os, supporting various single-ended and differential I/O standards like LVCMOS and LVDS.
