The **LCMXO2-2000HC-4TG100C** is a non-volatile Field Programmable Gate Array (FPGA) from the **MachXO2 family** by Lattice Semiconductor. It is designed to bridge the gap between low-density CPLDs (Complex Programmable Logic Devices) and high-performance FPGAs, focusing on low power consumption and high system integration. --- ## 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Logic Cells (LUTs)** | 2112 Look-Up Tables | | **User I/O Count** | 79 I/O pins | | **Embedded Block RAM (EBR)** | 74 Kbits | | **User Flash Memory** | 64 Kbits | | **Voltage Supply (Core)** | 2.375V to 3.465V | | **Operating Temperature** | 0°C to 85°C (Commercial Grade) | | **Package Type** | TQFP-100 (Thin Quad Flat Pack) | | **Speed Grade** | -4 (Standard speed) | --- ## 2. Key Internal Features ### A. Non-Volatile Technology Unlike traditional FPGAs that require an external SPI Flash to load the configuration at power-up, the MachXO2 features **on-chip Flash memory**. This allows for: * **Instant-on capability:** The device is operational within microseconds of power-up. * **Security:** Bitstream encryption and locking to prevent IP theft. ### B. Hardened IP Cores To save logic cells for user applications, Lattice integrated "Hardened" functions (physical circuits dedicated to specific tasks): * **I2C and SPI Controllers:** Dedicated hardware for serial communication. * **Timer/Counters:** 16-bit hardware timers. * **WISHBONE Bus:** Internal interface for connecting IP cores. ### C. Flexible I/O (SysIO) The 79 user I/Os are highly programmable, supporting: * Multiple standards (LVCMOS, LVTTL, PCI, LVDS, etc.). * Programmable drive strength and slew rate. * Internal pull-up/pull-down resistors. --- ## 3. Typical Applications The MachXO2 series is frequently used in the following scenarios: 1. **System Control:** Managing power-up sequencing, reset generation, and glue logic on motherboards. 2. **Interface Bridging:** Converting data formats between different sensors or processors (e.g., I2C to SPI, or GPIO expansion). 3. **Sensor Hubs:** Aggregating data from multiple low-speed sensors before sending it to a main Application Processor. 4. **Display Driving:** Handling small character or graphic LCD interfaces. --- ## 4.
