The **LCMXO2-2000ZE-3FTG256C** is a member of the MachXO2 family produced by Lattice Semiconductor. It is categorized as an "Ultra Low Power" FPGA (Field Programmable Gate Array), often referred to as a Bridging and I/O expansion device. --- ## 1. Technical Specifications Table | Feature | Details | | :--- | :--- | | **Manufacturer** | Lattice Semiconductor | | **Logic Cells (LUTs)** | 2112 | | **User I/Os** | 206 | | **Embedded Block RAM (EBR)** | 74 Kbits | | **Distributed RAM** | 16 Kbits | | **Flash Memory** | User Flash Memory (UFM) for non-volatile storage | | **Voltage Supply (Core)** | 1.14V to 1.26V (ZE variant is Low Power) | | **Operating Temperature** | 0°C ~ 85°C (Commercial Grade) | | **Package / Case** | 256-LBGA (17x17 mm) | | **Mounting Type** | Surface Mount | --- ## 2. Part Number Breakdown Understanding the suffix codes helps identify the specific capabilities of this component: * **LCMXO2**: MachXO2 Product Family. * **2000**: Density indicator (approx. 2000 Look-Up Tables). * **ZE**: "Zero Power" Enhanced - optimized for ultra-low power consumption. * **3**: Speed Grade (3 is the standard speed for this series). * **FTG256**: Package type (256-ball Fine-Pitch Thin BGA, Lead-Free). * **C**: Temperature Grade (Commercial). --- ## 3. Key Electronic Features ### Instant-On Capability Unlike traditional FPGAs that require an external PROM to load configuration data, the MachXO2 series has **on-chip Flash memory**. This allows the device to be active within milliseconds of power-up, making it ideal for system control and reset sequencing. ### Hardened IP Blocks To save logic cells for user applications, the chip includes built-in "Hardened" functions: * **I2C & SPI Interfaces:** Dedicated hardware for serial communication. * **Timer/Counter:** Useful for basic PWM or timing tasks. * **PLL (Phase Locked Loop):** For frequency synthesis and clock management. ### Power Management The **ZE (Zero Power)** variant is designed specifically for battery-operated devices. It features: * Extremely low static current. * Single-supply operation capability (depending on I/O requirements). --- ## 4. Common Applications Due to its low power and high I/O count relative to its size, it is commonly used for: 1. **I/O Expansion:** Adding extra pins to a microcontroller that has run out of GPIOs. 2. **Interface Bridging:** Converting signals between different standards (e.g., I2C to Parallel, or LVDS). 3. **Sensor Hubs:** Managing data from multiple sensors before passing it to a main processor. 4. **Power Sequencing:** Controlling the order in which different power rails on a motherboard turn on.
