The **LCMXO2-2000HC-5TG144I** is a non-volatile Field Programmable Gate Array (FPGA) belonging to the **MachXO2** family from Lattice Semiconductor. It is designed to bridge the gap between low-density CPLDs (Complex Programmable Logic Devices) and high-performance FPGAs. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the specific capabilities of this component: | Code Segment | Description | | :--- | :--- | | **LCMXO2** | MachXO2 product family | | **2000** | Approximately 2000 Look-Up Tables (LUTs) | | **HC** | High Performance / High Voltage (Core Vcc = 2.5V to 3.3V) | | **5** | Speed Grade (5 is standard/faster) | | **TG144** | 144-pin TQFP package (Thin Quad Flat Pack) | | **I** | Industrial Temperature Range (-40°C to +100°C) | --- ### 2. Key Technical Specifications This device is highly integrated and includes several "system-on-chip" features that reduce the need for external components. * **Logic Density:** 2112 Look-Up Tables (LUT4). * **Embedded Memory:** * 74 Kbits of Embedded Block RAM (EBR). * 64 Kbits of User Flash Memory (UFM) for non-volatile data storage. * **I/O Capabilities:** 111 User I/Os, supporting various standards (LVCMOS, LVTTL, PCI, LVDS). * **Hardened IP Blocks:** Includes built-in I2C, SPI, and Timer/Counters, which saves logic cells for other tasks. * **Instant-on:** Boots in milliseconds from internal Flash memory. --- ### 3. Internal Architecture The architecture is optimized for low-power and low-cost applications: 1. **PFU (Programmable Functional Unit):** The core logic building block containing LUTs, registers, and carry logic. 2. **Routing:** A hierarchical interconnect structure that allows fast signal propagation between PFUs. 3. **Clocking:** Features 2 Phase-Locked Loops (PLLs) for frequency synthesis and jitter reduction. 4. **Configuration:** It uses SRAM-based logic but features on-chip Flash, allowing it to be "self-configuring" without an external PROM. --- ### 4. Common Applications Due to its small footprint and industrial rating, it is frequently used in: * **System Control:** Power-up sequencing, reset distribution, and glue logic. * **Interface Bridging:** Converting signals between different protocols (e.g., I2C to Parallel). * **I/O Expansion:** Adding more GPIOs to a microcontroller or SoC. * **Display Driving:** Driving small character or graphic LCDs. --- ### 5. Electrical Characteristics ```yaml Supply_Voltage_Core: 2.5V to 3.3V IO_Voltage_Support: 1.2V to 3.3V Static_Current: Low power (typically < 20mA depending on design) Programming_Interface: JTAG, SPI, or I2C ```
