The **MachXO2-2000ZE** is a low-power, non-volatile FPGA (Field Programmable Gate Array) manufactured by Lattice Semiconductor. It belongs to the MachXO2 family, which is designed to bridge the gap between traditional CPLDs (Complex Programmable Logic Devices) and high-performance FPGAs. --- ### ## 1. Key Technical Specifications The "ZE" suffix specifically denotes the **ultra-low power** version of the MachXO2 architecture, operating at a nominal 1.2V core voltage. | Feature | Specification | | :--- | :--- | | **Look-up Tables (LUTs)** | 2112 | | **Logic Cells** | 2112 | | **Embedded Block RAM (EBR)** | 72 Kbits | | **User Flash Memory (UFM)** | 64 Kbits | | **Distributed RAM** | 16 Kbits | | **Core Voltage ($V_{CC}$)** | 1.2V | | **Maximum User I/Os** | Up to 160 (depending on package) | | **Flash Configuration** | On-chip, non-volatile (Instant-on) | --- ### ## 2. Core Functional Components The MachXO2-2000ZE is built around several specialized hard-coded blocks that reduce the need for manual logic programming: * **Logic Blocks:** Based on 4-input LUTs. These handle the combinatorial logic and registers. * **WISHBONE Interface:** A standardized bus architecture used to connect internal components. * **Hardened I2C/SPI/Timer:** Unlike many FPGAs where you must use logic cells to create these interfaces, this chip has dedicated "hard" IP for: * Two $I^2C$ interfaces. * One SPI interface. * A 16-bit Timer/Counter. * **Internal Oscillator:** Includes a built-in clock source, eliminating the need for an external crystal for simple tasks. * **Non-Volatile Flash:** Because it contains internal Flash memory, the configuration is stored on-chip. It powers up "instantly" (typically < 1ms), whereas many other FPGAs must load their code from an external ROM. --- ### ## 3. Power and Physical Characteristics The "ZE" series is optimized for battery-operated or thermally constrained environments. * **Ultra-Low Power:** It features a "Zero Power" mode, making it ideal for mobile devices. * **Package Options:** Available in various packages including TQFP (0.5mm pitch) and small form-factor BGA (0.4mm or 0.8mm pitch). * **I/O Flexibility:** Supports multiple I/O standards like LVCMOS (3.3V, 2.5V, 1.8V, 1.5V, 1.2V), LVTTL, and differential signaling like LVDS. --- ### ## 4. Common Use Cases The MachXO2-2000ZE is frequently used for: 1. **System Control:** Power sequencing, reset generation, and glue logic between a CPU and peripherals. 2. **Interface Bridging:** Converting signals between different protocols (e.g., $I^2C$ to SPI or UART to Parallel). 3. **I/O Expansion:** Adding more GPIO pins to a microcontroller that has run out of physical pins. 4. **Display Driving:** Handling timing for small LCD screens or LED matrices. ---
