The Lattice LCMXO2-1200HC-5TG100C Low-Power FPGA: Architecture, Features, and Target Applications
The demand for flexible, low-power, and cost-effective programmable logic solutions continues to grow across a wide spectrum of electronic applications. Addressing this need, the Lattice LCMXO2-1200HC-5TG100C stands out as a prominent member of the Lattice MachXO2™ FPGA family. This device is engineered to provide an optimal balance of power, performance, and price, making it an ideal choice for bridging, control, and interface functions in modern systems.
Architecture and Core Features
At the heart of the LCMXO2-1200HC-5TG100C is a high-efficiency programmable logic architecture. It features 1280 Look-Up Tables (LUTs) alongside distributed and embedded block memory, providing ample resources for implementing complex glue logic and state machines. A key architectural advantage is its non-volatile, flash-based technology. This eliminates the need for an external boot PROM, simplifies the board design, and allows for instant-on operation upon power-up, which is critical for control applications.
The device is housed in a compact 5mm x 5mm, 100-ball TQFP (5TG100C) package, making it suitable for space-constrained PCB designs. Despite its small size, it offers a generous number of user I/Os, supporting various I/O standards such as LVCMOS, LVTTL, and PCI.
Emphasis on Ultra-Low Power Consumption
A defining characteristic of this FPGA is its exceptionally low static power consumption. Leveraging a 65nm embedded flash process, the device consumes a fraction of the power of SRAM-based FPGAs. This makes it perfectly suited for battery-powered and portable devices where energy efficiency is paramount. Designers can use this FPGA to manage power sequencing, sensor interfacing, and system control without becoming a significant drain on the power budget.
Integrated Features and Security
Beyond the core fabric, the LCMXO2-1200HC is packed with valuable integrated features that reduce component count and total system cost. These include:
User Flash Memory (UFM): Dedicated non-volatile storage for holding user data, serial numbers, or system parameters.
Pre-Engineered Embedded Functions: Hardened IP blocks for I2C, SPI, and timer/counter functions are included, saving logic resources and simplifying design implementation.
On-Chip Oscillator: Built-in oscillators eliminate the need for an external crystal for many applications, further reducing BOM cost and board space.
TransFR Technology: This feature enables in-field updates and reconfiguration of the FPGA with minimal system disruption, supporting robust maintenance and upgrade paths.
Security: The flash cells are inherently secure, offering protection against unauthorized access and intellectual property (IP) theft, a crucial consideration for proprietary designs.
Target Applications
The combination of low power, small form factor, and integrated features directs the LCMXO2-1200HC-5TG100C towards several key application areas:
System Management: It is ideal for power sequencing, voltage level translation, and supervisory and control logic in larger systems like servers, communications equipment, and industrial controllers.
Portable and Consumer Electronics: Its low power consumption makes it perfect for interfacing sensors, managing displays, and implementing custom logic in handheld gadgets, wearables, and other consumer products.
Industrial and Automotive: The device's robustness and instant-on capability are valuable in industrial control systems, motor control, and automotive infotainment for interface bridging and GPIO expansion.
Communications Infrastructure: Used for board management, interface bridging (e.g., SPI to I2C), and signal integrity control in networking hardware.
