The **LCMXO2-2000HC-6TG100C** is a low-power, non-volatile FPGA (Field Programmable Gate Array) belonging to the **MachXO2** family developed by Lattice Semiconductor. It is widely used in bridge logic, system control, and interface expansion applications. --- ### 1. Key Technical Specifications The part number can be decoded to understand its specific electronic characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Logic Cells** | 2,112 LUTs | The primary programmable logic resource. | | **User I/O** | 79 Pins | Number of programmable input/output pins. | | **Package** | TQFP-100 | Thin Quad Flat Pack with 100 pins (0.5mm pitch). | | **Speed Grade** | -6 | Standard performance (higher number is faster in this series). | | **Voltage Supply** | 2.5V to 3.3V | Operates on standard high-performance rails. | | **Memory** | 75 Kbits | Total Embedded Block RAM (EBR). | | **Flash Memory** | 64 Kbits | User Flash Memory (UFM) for non-volatile storage. | --- ### 2. Internal Architecture Components This chip integrates several fixed-function blocks alongside programmable logic to reduce the need for external components: * **Hardened IP Blocks:** Includes dedicated circuits for **I2C, SPI, and Timer/Counters**. This saves programmable logic cells for other tasks. * **PLL (Phase-Locked Loop):** One internal PLL is available for clock frequency synthesis and skew management. * **Non-Volatile Configuration:** Unlike many FPGAs that require an external PROM/Flash chip to load code at boot, this device has **on-chip Flash memory**. It is "instant-on." * **FlashBAK Technology:** Supports "Background Programming," allowing the device to be updated while it is still operating. --- ### 3. Application Use Cases Due to its small form factor and low power consumption, it is commonly found in: 1. **Interface Bridging:** Converting signals between different standards (e.g., I2C to parallel, or LVDS to CMOS). 2. **Power Sequencing:** Managing the power-up/down timing of complex SoCs and CPUs on a PCB. 3. **GPIO Expansion:** Adding extra I/O ports to microcontrollers that have run out of pins. 4. **Display Driving:** Handling timing signals for small LCD or OLED screens. --- ### 4.
