Functional Electronic Components The internal architecture of the LCMXO2-2000ZE consists of several specialized electronic blocks: #### A. Logic Blocks and Memory * **PFUs (Programmable Functional Units):** Contain the LUTs, registers, and logic paths to perform math, multiplexing, and logic gates. * **Embedded Block RAM (EBR):** Dedicated memory (72 Kbits) for data storage, FIFO buffers, or small lookup tables. * **User Flash Memory (UFM):** 64 Kbits of non-volatile memory that can be used for configuration or storing persistent data (like serial numbers). #### B. Clocking and Power * **Internal Oscillator:** Eliminates the need for an external crystal for non-critical timing tasks. * **Phase Locked Loops (PLLs):** One onboard PLL for frequency synthesis and clock phase adjustment. * **Low Power Mode:** The "ZE" series is optimized for extremely low static power consumption (microwatts). #### C. Dedicated Hardware Interfaces The MachXO2 includes hard-coded (non-logic based) blocks for common communication protocols to save space: * **I2C & SPI Hardened IPs:** Dedicated circuitry for these protocols. * **Timer/Counters:** 16-bit timers available for system monitoring. --- ### 3.
