The **LCMXO2-2000HC-6TG144I** is a member of the MachXO2 family from Lattice Semiconductor. It is an ultra-low-power, instant-on, non-volatile PLD (Programmable Logic Device) designed to bridge the gap between low-density CPLDs and high-capacity FPGAs. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Logic Cells (LUTs)** | 2112 LUT4s | | **Embedded Block RAM (EBR)** | 74 Kbits | | **User Flash Memory (UFM)** | 64 Kbits | | **I/O Pins** | 111 User I/Os | | **Voltage Supply (Core)** | 2.5V to 3.3V ("HC" series) | | **Package Type** | TQFP-144 (Thin Quad Flat Pack) | | **Speed Grade** | -6 (Standard High Performance) | | **Temperature Range** | -40°C to +100°C (Industrial Grade) | --- ### 2. Functional Architecture The device architecture is optimized for system control and interface expansion: * **Non-Volatile Configuration:** It features on-chip Flash memory. This means the device does not require an external PROM to load its configuration on power-up; it is "Instant-on." * **Hardened IP Blocks:** Unlike traditional FPGAs where you use logic cells for common protocols, this chip includes dedicated hardware (Hard IP) for: * **I2C Interfaces** (up to 2 controllers) * **SPI Interface** * **Timer/Counters** * **WISHBONE Bus:** An internal bus structure that allows easy connection between the hardened IP and the user-defined logic. --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying its specific capabilities: | Code Segment | Meaning | | :--- | :--- | | **LCMXO2** | MachXO2 Product Family | | **2000** | Logic Density (~2112 Look-Up Tables) | | **HC** | High-Voltage Core (2.5V / 3.3V Operation) | | **6** | Speed Grade (Scale of 4 to 6, where 6 is fastest) | | **TG144** | 144-pin TQFP Lead-Free Package | | **I** | Industrial Temperature Rating | --- ### 4. Typical Applications * **System Glue Logic:** Interfacing between CPUs and peripherals with mismatched voltage levels or protocols. * **Power Sequencing:** Managing the power-up and power-down cycles of complex SoCs and FPGAs. * **I/O Expansion:** Adding more GPIOs, PWMs, or UARTs to a microcontroller that has run out of pins. * **Display Interfacing:** Driving small LCD character or graphic displays.
