Lattice LC4128V-75T100-10I: Comprehensive Technical Overview and Application Guide
The Lattice LC4128V-75T100-10I is a member of the high-performance, low-power LatticeXP2 family of non-volatile FPGAs. This specific device combines the instant-on capability, security, and reconfigurability of SRAM-based FPGAs with the non-volatility and single-chip convenience of traditional FPGAs. Engineered for a wide range of applications, from consumer electronics to industrial control systems, this IC represents a significant solution for designers seeking a balance between power, performance, and cost.
Architectural Overview and Key Specifications
At its core, the LC4128V-75T100-10I features 1280 Look-Up Tables (LUTs), providing ample resources for implementing complex combinatorial and sequential logic. The device is built on a 90nm CMOS process with embedded Flash technology, which allows it to be live-updated and reprogrammed in-circuit. A critical feature is its non-volatile configuration memory, enabling the FPGA to power up instantly without needing an external boot PROM.
The "-75" speed grade denotes a robust performance level, while the "T100" package is a 100-pin Thin Quad Flat Pack (TQFP), making it suitable for space-constrained PCB designs. The device operates over a standard industrial temperature range (-40°C to 100°C), ensuring reliability in harsh environments. It supports a versatile I/O voltage range from 1.2V to 3.3V, allowing for easy interfacing with various other components in a system.
Distinguishing Features and Advantages
1. Live Update (TransFR Technology): This technology facilitates seamless field reconfigurations and background updates without interrupting the system's operation, a vital feature for mission-critical applications.
2. High Security: The embedded configuration memory is inherently secure, protecting intellectual property from unauthorized access, reverse engineering, and copying. This is a major advantage over volatile SRAM-based FPGAs.
3. Low Power Consumption: The LatticeXP2 family is renowned for its low static and dynamic power dissipation, which is crucial for portable and battery-operated devices.
4. Small Form Factor: The TQFP package offers a excellent balance between pin count and physical size, ideal for applications where board real estate is limited.
Primary Application Areas
The technical profile of the LC4128V-75T100-10I makes it exceptionally well-suited for several key markets:
Industrial Control and Automation: Used for motor control, sensor interfacing, and programmable logic controllers (PLCs) due to its live-update capability and industrial temperature range.
Communications Infrastructure: Serves in network interface cards, routers, and switches for bus bridging, I/O expansion, and protocol translation.
Consumer Electronics: Ideal for portable devices, digital cameras, and displays where low power consumption and a small footprint are paramount.
Automotive Systems: Employed in infotainment systems and driver assistance modules, leveraging its reliability and instant-on feature.
Medical Equipment: Used in portable diagnostic and monitoring devices where low power and high reliability are non-negotiable.
