NXP's LPC81xM MCU family is designed to offer cost-effective solutions with powerful performance. These microcontrollers are built on Arm Cortex-M0+ cores, providing efficient processing capabilities and low power consumption.
The LPC81xM family stands out for its versatile timing, connectivity, and analog peripherals. It combines these features into a compact and easy-to-use package, making it ideal for a wide range of applications. Designers can benefit from the three select peripherals that facilitate the transition into the 32-bit space.
One key feature of the LPC81xM family is the switch matrix, which allows designers to map pins according to their requirements. This flexibility simplifies component routing on a PCB, making the design process more efficient.
Another notable feature is the SCTimer, which can be configured to generate a variety of timing or PWM waveforms without requiring intervention from the CPU. This capability enhances the MCU's versatility and allows for precise timing control.
To meet the demands of serial communication, the LPC81xM MCU family includes a pattern-match engine. This engine can be configured to generate interrupts based on user-defined Boolean operations on its eight pins. This simplifies the implementation of serial communication requirements and streamlines the overall system design.
The LPC800 series, including LPC83x family, offers scalability and compatibility across subfamilies and packages. Critical pinouts are shared, allowing customers to easily swap or scale packages and subfamilies as their needs evolve. The LPC83x family builds upon the functionality of the LPC81x by increasing the Flash size and incorporating a 12-bit ADC with sample rates of up to 1.2 Msps. This enhances the MCU's capabilities in terms of data acquisition and processing.
NXP's LPC81xM MCU family is fully supported by the MCUXpresso Software and Tools, a comprehensive set of free software development tools for NXP's microcontrollers. The MCUXpresso SDK includes project files for popular development environments such as Keil MDK and IAR EWARM, ensuring seamless integration and ease of development.
In summary, NXP's LPC81xM MCU family offers low-cost microcontroller solutions based on Arm Cortex-M0+ cores. With versatile timing, connectivity, and analog peripherals, these compact and user-friendly MCUs provide efficient and cost-effective options for various applications. Features like the switch matrix, SCTimer, and pattern-match engine simplify component routing, enable precise timing control, and streamline serial communication requirements. The LPC800 series offers scalability and easy pinout swapping, while the LPC83x family enhances functionality with increased Flash size and a high-resolution ADC. Supported by NXP's MCUXpresso Software and Tools, these MCUs ensure seamless development and compatibility with other microcontrollers.
