The **LCMXO2-2000ZE-2TG100C** is a non-volatile, low-power FPGA (Field Programmable Gate Array) from the **MachXO2** family, manufactured by Lattice Semiconductor. This specific part is widely used for system control functions, glue logic, and interface bridging. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the specific capabilities of this component: | Code Segment | Meaning | | :--- | :--- | | **LCMXO2** | MachXO2 Product Family | | **2000** | Logic Density (approx. 2112 Look-Up Tables / LUTs) | | **ZE** | Ultra Low Power (1.2V Core Voltage) | | **2** | Speed Grade (Standard performance) | | **TG100** | Package Type: 100-pin TQFP (Thin Quad Flat Pack) | | **C** | Temperature Grade: Commercial (0°C to 85°C) | --- ### 2. Technical Specifications The "ZE" variant is specifically optimized for power-sensitive applications like handheld devices. | Parameter | Specification | | :--- | :--- | | **Logic Cells (LUTs)** | 2,112 | | **User I/O Count** | 79 Pins | | **Embedded Block RAM** | 74 Kbits | | **Distributed RAM** | 16 Kbits | | **User Flash Memory** | 64 Kbits | | **Core Supply Voltage** | 1.2 V | | **I/O Bank Voltage** | 1.2V to 3.3V (Multiple banks) | | **Hardened IP Blocks** | I2C, SPI, Timer/Counter | --- ### 3. Key Electronic Features #### A. Instant-On Technology Unlike high-end FPGAs that require an external Flash memory to load their configuration at startup, the MachXO2 features **on-chip Flash**. This allows the device to become active in microseconds, making it ideal for managing power-up sequences of larger processors. #### B. Hardened Primary IP To save logic cells for custom tasks, Lattice has "hardened" (built-in as physical circuits) common interfaces: * Two **I2C** controllers. * One **SPI** controller. * One **User Flash Memory (UFM)** for data storage or ID codes. #### C. Low Power Consumption The "ZE" series uses a 1.2V core, significantly reducing static power consumption (standby current) compared to the standard "HC" (High-Performance 2.5V/3.3V) variants. --- ### 4. Typical Applications * **Power Sequencing:** Managing the order in which different voltage rails turn on in a complex system. * **I/O Expansion:** Adding more GPIOs to a microcontroller that has run out of pins. * **Level Shifting:** Bridging communication between a 1.2V CPU and 3.3V peripherals. * **Display Interface:** Driving small character or segment LCDs.
