### Overview of LCMXO2-2000HC-5MG132C The **LCMXO2-2000HC-5MG132C** is a high-performance, low-power Field Programmable Gate Array (FPGA) belonging to the **MachXO2 family** by Lattice Semiconductor. It is specifically designed for system applications that require bridging, I/O expansion, and control logic in a compact form factor. --- ### Core Specifications Below are the primary electronic characteristics and internal architecture details: | Parameter | Specification | | :--- | :--- | | **Logic Cells (LUTs)** | 2,112 | | **Embedded Block RAM (EBR)** | 74 Kbits | | **User Flash Memory (UFM)** | 74 Kbits | | **Operating Voltage (Vcc)** | 2.5V to 3.3V | | **Speed Grade** | -5 (Standard speed) | | **Package Type** | 132-ball csBGA (Chip Scale Ball Grid Array) | | **I/O Count** | 104 User I/Os | | **Temperature Grade** | Commercial (0°C to 85°C) | --- ### Key Internal Features #### 1. Logic Architecture The device is built on a Look-Up Table (LUT) based architecture. It uses **4-input LUTs** combined with dedicated registers and carry logic to implement complex digital functions efficiently. #### 2. Non-Volatile Memory Unlike traditional FPGAs that require an external SPI Flash to load the configuration, the MachXO2 features **on-chip Flash**. This allows for: * **Instant-on capability:** The FPGA is active within milliseconds of power-up. * **Security:** Bitstream data is hidden inside the chip, making it harder to reverse engineer. #### 3. Hardened IP Blocks To save logic cells and power, the chip includes dedicated hardware blocks for common functions: * **I2C and SPI Interfaces:** Hardened controllers for serial communication. * **Timer/Counters:** Dedicated 16-bit timers. * **PLL (Phase Locked Loop):** One internal PLL for clock frequency synthesis and phase adjustment. #### 4. I/O Capabilities The MG132 package provides a high density of I/Os. These pins support multiple standards: * LVCMOS (3.3V, 2.5V, 1.8V, 1.5V, 1.2V) * LVTTL * Differential inputs (LVDS, Bus-LVDS, MLVDS) --- ### Part Number Breakdown Understanding the nomenclature helps in identifying the specific variant: * **LCMXO2:** MachXO2 Product Family. * **2000:** Approximately 2000 Logic Look-Up Tables. * **HC:** High Performance / 2.5V to 3.3V Core Voltage. * **5:** Speed Grade (5 is standard; higher numbers are faster in some Lattice families). * **MG132:** 132-ball csBGA package (8mm x 8mm). * **C:** Commercial Temperature Grade. --- ### Typical Applications * **System Control:** Power sequencing, reset generation, and status monitoring. * **I/O Expansion:** Adding more GPIOs to a microcontroller via SPI or I2C. * **Interface Bridging:** Converting signals between different logic levels or protocols (e.g., I2C to Parallel). * **Consumer Electronics:** Handheld devices, cameras, and display controllers due to low static power consumption.
