The **LCMXO2-256UHC1UWG36CTRES** is a specific part number from the **MachXO2** family of Field Programmable Gate Arrays (FPGAs) manufactured by **Lattice Semiconductor**. This family is designed for low-power, low-cost applications, bridge functions, and system control. --- ## 1. Technical Specification Breakdown The part number itself acts as a code for its primary specifications: | Feature | Specification | Description | | :--- | :--- | :--- | | **Family** | MachXO2 | Non-volatile, instant-on FPGA architecture. | | **Density** | 256 | Approximately 256 Look-Up Tables (LUTs). | | **Performance** | HC | High Performance / Low Power (1.2V core). | | **Voltage** | 1 | Core Voltage supply level. | | **Package Type** | UWG | WLCSP (Wafer Level Chip Scale Package). | | **Pin Count** | 36 | 36-ball package. | | **Temperature** | C | Commercial Grade (0°C to 85°C). | | **Shipping** | TR | Tape & Reel packaging. | --- ## 2. Key Electronic Features ### A. Architecture - **Look-Up Tables (LUTs):** 256. This is a very small density, ideal for glue logic, simple state machines, or I/O expansion. - **Embedded Flash:** Unlike many FPGAs, MachXO2 devices store their configuration in internal Flash memory. This means they are **"Instant-On"** and do not require an external configuration PROM. - **Hardened IP:** Includes hardened blocks for I2C, SPI, and User Flash Memory (UFM), which saves LUT resources for other tasks. ### B. Power & Performance - **Low Power:** Designed for mobile and handheld devices where battery life is critical. - **Core Voltage:** Typically operates at 1.2V, reducing static and dynamic power consumption. ### C. Package & Physicals (UWG36) - **Ultra-Small Form Factor:** The WLCSP (Wafer Level Chip Scale Package) is extremely tiny, making it suitable for wearable electronics or space-constrained PCB designs. - **I/O Pins:** Offers up to 28 User I/Os despite the small footprint. --- ## 3. Common Applications Due to its small logic density and tiny physical size, this part is typically used for: * **I/O Level Shifting:** Converting signals between different voltage domains. * **System Reset Logic:** Managing the power-up sequence of larger processors (SoCs). * **Interface Bridging:** Converting I2C to SPI or PWM signals. * **LED Control:** Simple drive logic for status indicators. --- ## 4. Design Support To program and simulate this device, engineers use the **Lattice Diamond** software suite. ```tcl # Example Constraint File (LPF) snippet for MachXO2 LOCATE COMP "led_out" SITE "A1"; # Assigning a pin to a physical ball IOBUF PORT "led_out" IO_TYPE=LVCMOS33; # Defining voltage standard ```
