The **LCMXO2-2000UHC-6FG484I** is a high-performance FPGA (Field Programmable Gate Array) belonging to the **MachXO2** family by Lattice Semiconductor. This specific series is designed for low-power, instant-on applications, bridging the gap between CPLDs (Complex Programmable Logic Devices) and high-density FPGAs. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the specific capabilities of this component: | Segment | Code | Meaning | |:--- |:--- |:--- | | **Family** | LCMXO2 | MachXO2 Family (Ultra-low power, instant-on) | | **Logic Density** | 2000 | Approximately 2000 Look-Up Tables (LUTs) | | **Power/Voltage** | UHC | Ultra High Performance / 2.5V or 3.3V VCC | | **Speed Grade** | -6 | Performance rating (Higher is faster in MachXO2) | | **Package** | FG484 | Fine-pitch Ball Grid Array (fbga) with 484 balls | | **Temperature** | I | Industrial grade (-40°C to +100°C) | --- ### 2. Key Technical Specifications This device integrates several "system-on-chip" features that reduce the need for external components. * **Logic Capacity:** 2112 Look-Up Tables (LUTs). * **User I/O:** Provides 334 available I/O pins, supporting various signaling standards (LVCMOS, LVDS, etc.). * **Embedded Memory:** * **EBR (Embedded Block RAM):** 72 Kbits. * **Distributed RAM:** 16 Kbits. * **User Flash Memory:** 64 Kbits (for non-volatile data storage). * **Hard IP Blocks:** Includes dedicated hardware for $I^2C$, SPI, and Timer/Counters, which saves logic cells for other tasks. * **Clock Management:** Features 2 Phase-Locked Loops (PLLs) for frequency synthesis and jitter reduction. --- ### 3. Core Features & Advantages #### **Instant-On & Non-Volatile** Unlike traditional FPGAs that require an external Flash chip to load the configuration at power-up, the MachXO2 series stores its configuration internally. This allows the chip to become active in microseconds, making it ideal for system control and power-sequencing. #### **Bridging and Expansion** Because of its high I/O count relative to its size, it is frequently used for: * **Bus Bridging:** Converting signals between different protocols (e.g., $I^2C$ to Parallel). * **I/O Expansion:** Adding more GPIOs to a microcontroller or SoC. * **Level Shifting:** Interfacing components that operate at different voltage levels. #### **Low Power Consumption** The "UHC" variant is optimized for high-performance while maintaining a low static power profile, suitable for industrial equipment where heat dissipation or battery life is a concern. --- ### 4. Application Examples * **Industrial Automation:** Sensor data aggregation and motor control logic. * **Telecommunications:** Line card management and backplane interfacing. * **Consumer Electronics:** Display driving and camera interface bridging. * **Computing:** Power management sequencing on server motherboards.
