The **LCMXO2-2000HC-5TG144C** is a member of the **MachXO2** family from Lattice Semiconductor. This device is an ultra-low-power, instant-on, non-volatile PLD (Programmable Logic Device) that bridges the gap between low-density CPLDs and high-capacity FPGAs. --- ### 1. Key Technical Specifications The part number itself acts as a code for its primary specifications: | Feature | Specification | |:---|:---| | **Logic Cells (LUTs)** | 2112 Look-Up Tables | | **User I/O Count** | 111 I/O pins | | **Package Type** | TQFP-144 (Thin Quad Flat Pack) | | **Speed Grade** | -5 (High Performance) | | **Voltage Supply** | 2.5V to 3.3V (HC - High Core Voltage) | | **Temperature Range** | 0°C to 85°C (Commercial Grade) | --- ### 2. Internal Architecture & Features This chip integrates several components that usually require external circuitry: * **Embedded Flash:** The configuration is stored on-chip. This allows for "Instant-on" capability (the chip starts working immediately upon power-up) and high security against IP theft. * **Embedded Function Blocks (EFB):** It contains hardened IP for common interfaces, saving logic cells for other tasks: * $I^2C$ Master/Slave interfaces. * SPI interface. * Timer/Counters. * **Memory Resources:** * **EBR (Embedded Block RAM):** 72 Kbits for data buffering. * **Distributed RAM:** 16 Kbits. * **Flash Memory:** 64 Kbits of User Flash Memory (UFM) for non-volatile data storage. * **Phase Locked Loops (PLLs):** One system PLL for frequency synthesis and clock management. --- ### 3. Pinout and Physical Characteristics The **TG144** package is a surface-mount component with a fine pitch. ```text Package: TQFP-144 Dimensions: 20mm x 20mm Lead Pitch: 0.50 mm Pin Count: 144 Pins ``` --- ### 4. Typical Applications Due to its low power consumption and high I/O-to-logic ratio, it is commonly used for: 1. **System Control:** Power-up sequencing and reset generation. 2. **Interface Bridging:** Converting signals between different standards (e.g., LVCMOS to LVDS). 3. **I/O Expansion:** Adding more GPIOs to a microcontroller or SoC via $I^2C$ or SPI. 4. **Sensor Hubs:** Aggregating data from multiple low-speed sensors.
