The **LCMXO2-2000HC-5FTG256C** is a non-volatile Field Programmable Gate Array (FPGA) from the **MachXO2** family, manufactured by Lattice Semiconductor. This specific series is widely used for system control, interface bridging, and power management due to its low power consumption and high integration. --- ### 1. Key Technical Specifications | Parameter | Specification | |:--- |:--- | | **Logic Cells (LUTs)** | 2,112 Look-Up Tables | | **User I/O Count** | 206 I/O pins | | **Package** | FTBGA-256 (Fine-Pitch Thin BGA) | | **Voltage Supply (Core)** | 2.375V to 3.465V (HC Series) | | **Speed Grade** | -5 (Standard high performance) | | **Embedded RAM** | 74 Kbits (EBR) | | **Flash Memory** | User Flash Memory (UFM) included | | **Operating Temperature** | 0°C to 85°C (Commercial Grade) | --- ### 2. Core Architecture Features The MachXO2 architecture is designed to provide "instant-on" capability, meaning the device initializes immediately upon power-up without needing an external configuration memory. * **Look-Up Tables (LUT4):** The logic fabric is based on 4-input LUTs, which provide flexible logic implementation. * **Embedded Function Blocks (EFB):** It contains hardened IP blocks for common functions, saving logic cells: * **I2C / SPI Interfaces:** Hardware-based serial communication. * **Timer/Counters:** 16-bit hardware timers. * **PLL (Phase Locked Loop):** For clock frequency synthesis and distribution. * **Non-Volatile Configuration:** Uses on-chip Flash memory to store the configuration bitstream, eliminating the need for an external PROM. --- ### 3. Pinout and Physical Characteristics The **256-ball FTG256** package is a space-efficient BGA (Ball Grid Array) with a 1.0mm pitch. * **Banked I/O:** The I/Os are organized into multiple banks, allowing different banks to support different voltage standards (e.g., 1.8V, 2.5V, or 3.3V) simultaneously. * **Differential Signaling:** Supports LVDS (Low-Voltage Differential Signaling) for high-speed data transmission. * **Thermal Efficiency:** The BGA package provides good thermal dissipation compared to leaded packages like TQFP. --- ### 4. Part Number Breakdown Understanding the nomenclature helps in identifying variants: | Prefix | Density | Voltage | Speed | Package | Pins | Grade | |:--- |:--- |:--- |:--- |:--- |:--- |:--- | | **LCMXO2** | **2000** | **HC** | **-5** | **FTG** | **256** | **C** | | MachXO2 | ~2000 LUTs | High Vcc (2.5/3.3V) | Speed Rank | FTBGA (Lead-Free) | Ball Count | Commercial | --- ### 5. Common Applications * **I/O Expansion:** Adding more GPIOs to a microcontroller. * **Interface Bridging:** Converting signals (e.g., I2C to Parallel, or SPI to UART). * **System Control:** Power sequencing, reset generation, and Glue Logic. * **Display Driving:** Driving small character or graphic LCD modules.
