The **LCMXO2-7000HC-5TG144C** is a member of the MachXO2 family developed by Lattice Semiconductor. It is a non-volatile, low-power FPGA (Field Programmable Gate Array) designed for system applications like glue logic, bus bridging, and power management. --- ### 1. Key Technical Specifications Below are the primary technical parameters for this specific part number: | Parameter | Specification | | :--- | :--- | | **Logic Cells** | 6,864 Look-Up Tables (LUTs) | | **User I/O Count** | 114 I/Os | | **Voltage Supply** | 2.375V to 3.465V (Core) | | **Package / Case** | 144-LQFP (Low-profile Quad Flat Pack) | | **Operating Temperature** | 0°C to 85°C (Commercial Grade) | | **Embedded RAM** | 240 Kbits (EBR) | | **Flash Memory** | User Flash Memory (UFM) available | | **Speed Grade** | -5 (High Performance) | --- ### 2. Breakdown of the Part Number The alphanumeric string provides specific details about the component's architecture and packaging: * **LCMXO2**: MachXO2 Product Family. * **7000**: Density (approx. 7000 LUTs). * **HC**: High Capacity / High Performance (Standard voltage). * **5**: Speed grade (higher numbers generally indicate faster performance in this series). * **TG144**: 144-pin TQFP (Thin Quad Flat Pack) package. * **C**: Commercial temperature range. --- ### 3. Integrated Electronic Features This FPGA is unique because it integrates several features that typically require external components: * **Non-Volatile Configuration:** Unlike many FPGAs that require an external SPI Flash to load their configuration upon power-up, this chip has **on-chip Flash**. It is "instant-on." * **Hardened IP Blocks:** It contains dedicated hardware for common functions, saving logic cells for other tasks: * **I2C & SPI** interfaces. * **Timer/Counters**. * **PLLs (Phase Locked Loops)** for frequency synthesis and clock management. * **Flexible I/O:** The I/O pins support various standards (LVCMOS, LVTTL, PCI, LVDS) and include internal pull-ups. --- ### 4. Common Applications Due to its small footprint and low power consumption, it is frequently used for: 1. **System Control:** Power-up sequencing and reset signal generation. 2. **Interface Bridging:** Converting signals between different protocols (e.g., I2C to parallel). 3. **IO Expansion:** Adding more GPIOs to a microcontroller that has run out of pins. 4. **Display Drivers:** Driving small LCD or LED arrays.
