The **LCMXO2-2000HC-6FTG256C** is a non-volatile Field Programmable Gate Array (FPGA) belonging to the **MachXO2** family from Lattice Semiconductor. It is designed for low-power, instant-on applications, often used for system control, interface bridging, and power management. --- ## 1. Core Technical Specifications The internal architecture combines the flexibility of an FPGA with the low-cost and ease of use of a CPLD. | Feature | Specification | | :--- | :--- | | **Logic Cells (LUTs)** | 2,112 | | **User I/O Count** | 206 I/Os | | **Embedded Block RAM (EBR)** | 74 Kbits | | **User Flash Memory** | 64 Kbits | | **Supply Voltage (Core)** | 2.5V to 3.3V (HC Series) | | **Operating Temperature** | 0°C to 85°C (Commercial Grade) | | **Package Type** | FTBGA-256 (17mm x 17mm, 1.0mm pitch) | | **Speed Grade** | -6 (Standard performance) | --- ## 2. Key Internal Components ### A. Logic Fabric The device uses **Look-Up Tables (LUT4)** to implement combinatorial logic. Because it has roughly 2,000 LUTs, it is considered a "small-form" FPGA, ideal for glue logic rather than heavy digital signal processing. ### B. Configuration Flash Unlike high-end FPGAs that require an external SPI Flash to load code upon power-up, the MachXO2 has **on-chip Flash memory**. - **Instant-on:** It configures itself in milliseconds. - **Security:** Since the bitstream is stored internally, it is harder to intercept or clone. ### C. Hardened IP Cores To save logic cells for the user, the chip includes dedicated hardware (hardened IP) for common functions: - **I2C and SPI Controllers:** Dedicated hardware interfaces. - **Timer/Counters:** Built-in 16-bit timers. - **PLL (Phase Locked Loop):** One PLL is available for frequency synthesis and clock management. --- ## 3. Part Number Decoder Understanding the suffix helps in sourcing and hardware design: | Suffix | Meaning | | :--- | :--- | | **LCMXO2** | MachXO2 Product Family | | **2000** | Density (Approx. 2000 Logic Cells) | | **HC** | High Voltage Core (2.5V / 3.3V) | | **6** | Speed Grade (higher number is faster in Lattice naming) | | **FTG256** | 256-ball Fine-pitch Thin BGA (Lead-Free/RoHS) | | **C** | Commercial Temperature Range | --- ## 4. Typical Use Cases * **System Control:** Managing power-up sequences for larger CPUs or SoCs. * **I/O Expansion:** Adding more GPIOs to a microcontroller via SPI or I2C. * **Interface Bridging:** Converting signals between different standards (e.g., LVCMOS to LVDS). * **Display Driving:** Driving small character or graphic LCDs.
