The **LCMXO2-2000ZE-2TG100I** is a member of the **MachXO2** family of FPGAs (Field Programmable Gate Arrays) produced by Lattice Semiconductor. This specific part is an "Instant-on," low-power programmable logic device designed for system control, interface bridging, and power management. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the specific technical constraints of the chip: | Code Segment | Meaning | Specification | |:--- |:--- |:--- | | **LCMXO2** | Product Family | MachXO2 (PLD/FPGA) | | **2000** | Logic Density | ~2000 Look-Up Tables (LUTs) | | **ZE** | Power/Voltage | Ultra-low power, 1.2V core voltage | | **2** | Speed Grade | Standard Speed | | **TG100** | Package Type | 100-pin TQFP (Thin Quad Flat Pack) | | **I** | Temp Grade | Industrial (-40°C to +100°C) | --- ### 2. Core Technical Specifications The MachXO2 architecture bridges the gap between traditional CPLDs and high-performance FPGAs. * **Logic Capacity:** 2112 Look-Up Tables (LUT4). * **User I/O:** 79 programmable I/O pins. * **Embedded Memory:** * **EBR (Embedded Block RAM):** 72 Kbits. * **User Flash Memory:** 64 Kbits (non-volatile storage for configuration or data). * **Clocking:** Features 2 Phase Locked Loops (PLLs) for frequency synthesis and clock management. * **Hardened IP:** Includes dedicated hardware blocks for **I2C, SPI, and Timer/Counters**, which saves logic cells for other tasks. --- ### 3. Key Electronic Characteristics #### Power Consumption The "ZE" variant is optimized for battery-powered applications. It utilizes a 1.2V core, resulting in static power consumption as low as **sub-100µA**. #### Non-Volatile "Instant-On" Unlike high-end FPGAs that require an external SPI Flash to load code at boot, this chip has **on-chip Flash memory**. This allows the device to: 1. Initialize instantly (within microseconds). 2. Maintain its configuration without an external ROM. 3. Support "Transparent Updates" (reprogramming the background flash while the device is still running). #### Multi-Voltage I/O The 100-pin TQFP package supports multiple I/O banks. Each bank can be powered by a different voltage (1.2V, 1.5V, 1.8V, 2.5V, or 3.3V), allowing the chip to act as a **level shifter** between different electronic components. --- ### 4. Common Use Cases * **System Control:** Power sequencing of microprocessors and SOCs. * **Interface Bridging:** Converting signals between I2C, SPI, and UART. * **I/O Expansion:** Adding more GPIOs to a microcontroller that has run out of pins. * **Display Driving:** Driving small character or graphic LCDs.
