The **LCMXO2-256UZC2UWG49CTRES** is a specific part number belonging to the **MachXO2** family of Field Programmable Gate Arrays (FPGAs) manufactured by **Lattice Semiconductor**. These devices are known for being "Ultra-Low Power" and are designed for bridging, I/O expansion, and system control logic. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Logic Cells (LUTs)** | 256 Look-Up Tables | | **Architecture** | Instant-on, Non-volatile Flash-based | | **Package Type** | WLCSP-49 (Wafer Level Chip Scale Package) | | **Pins** | 49-ball | | **Voltage Supply** | 1.2V (Core) | | **I/O Capabilities** | Low power, high-speed differential support | --- ### 2. Part Number Breakdown Understanding the nomenclature helps identify the specific capabilities of this component: * **LCMXO2**: MachXO2 Family (Low density, instant-on FPGA). * **256**: Density of 256 Look-Up Tables (LUTs). This is a small-capacity device suited for simple logic. * **U**: Ultra-Low Power version (1.2V core). * **ZC**: Specific speed grade/power optimization (Standard performance/Low Power). * **2**: Speed Grade (2 is standard). * **UWG49**: Package code for the 49-ball WLCSP (extremely small footprint). * **CTR**: Refers to specific Tape and Reel packaging or custom variations for high-volume manufacturing. * **ES**: Engineering Sample (indicates this specific part may be for testing or pre-production evaluation). --- ### 3. Core Features * **Instant-On:** Because it stores its configuration in internal Flash memory, the FPGA starts operating microseconds after power-up, unlike SRAM-based FPGAs that require external boot memory. * **Embedded Functions:** It includes hard-coded I2C, SPI, and Timer/Counter blocks, which saves programmable logic space for other tasks. * **Small Footprint:** The WLCSP-49 package is designed for space-constrained applications like smartphones, wearables, or sensor modules. --- ### 4. Typical Applications 1. **I/O Expansion:** Adding more GPIOs to a microcontroller that has run out of pins. 2. **Interface Bridging:** Converting signals between different standards (e.g., I2C to parallel, or LVDS to CMOS). 3. **Power Sequencing:** Managing the power-up and power-down timing of various chips on a PCB. 4. **Sensor Hubs:** Aggregating data from multiple low-speed sensors before sending it to a primary application processor.
