The **LCMXO2-4000HC-5FG484C** belongs to the MachXO2 family from Lattice Semiconductor. It is a non-volatile, bridging, and control PLD (Programmable Logic Device) designed for system applications that require low power and high I/O density. --- ### ## Technical Specifications Breakdown The following table summarizes the core technical parameters of this specific part: | Parameter | Specification | | :--- | :--- | | **Product Series** | MachXO2 | | **Logic Look-Up Tables (LUTs)** | 4,320 | | **Embedded Block RAM (EBR)** | 92 Kbits | | **User Flash Memory (UFM)** | 96 Kbits | | **Number of I/Os** | 278 User I/Os | | **Speed Grade** | -5 (High Performance) | | **Voltage Supply** | 2.5V to 3.3V (HC Series) | | **Package Type** | fpBGA-484 (Fine Pitch Ball Grid Array) | | **Operating Temperature** | 0°C to 85°C (Commercial Grade) | --- ### ## Core Electronic Components & Features ### 1. Non-Volatile Configuration Unlike standard FPGAs that require an external SPI Flash to load their configuration on power-up, the MachXO2 uses **on-chip Flash memory**. This allows for "Instant-on" functionality (starts in microseconds) and enhances security by preventing the bitstream from being intercepted during loading. ### 2. Hardened IP Blocks To save logic cells for user applications, this chip includes dedicated hardware (Hard IP) for common functions: * **I2C & SPI Interfaces:** Dedicated controllers for system management. * **Timer/Counter:** Useful for generating PWM or system heartbeats. * **PLLs (Phase Locked Loops):** 2 PLLs are included for clock frequency synthesis and clock skew management. ### 3. Power Management The "HC" in the part number indicates a high-performance variant that operates on a **2.5V or 3.3V core voltage**. It features a "Low Power" mode that minimizes static leakage, making it suitable for battery-operated or heat-sensitive environments. ### 4. Advanced I/O Capabilities The 484-ball grid array provides a high density of I/O pins. These pins support: * **LVCMOS/LVTTL** signaling. * **Differential signaling** (LVDS). * **Hot-socketing** (allowing the chip to be plugged in while the system is powered). --- ### ## Application Use Cases * **System Control:** Power sequencing, reset generation, and glue logic. * **Interface Bridging:** Converting signals between different protocols (e.g., I2C to Parallel). * **Expansion:** Adding extra GPIOs to a microcontroller or SoC. ---
