NXP LPC800 Cortex-M0+ 32-Bit MCUs, LPC810 / LPC811 / LPC812

NXP LPC800 ARM Cortex™-M0+ 32-bit microcontrollers (MCUs) are available in low pin-count packages and offer easy-to-use peripherals addressing 8-bit application requirements while providing the 32-bit capabilities and exceptional power efficiency of the ARM® Cortex-M0 processor. Based on an ultra-low-power 30-MHz ARM Cortex-M0+ processor, LPC800 is fully compatible with the Cortex-M architecture and instruction set and offers superior code density to 8- / 16-bit architectures. The Cortex-M0+ features a two-stage pipeline that reduces power consumption while improving performance. LPC800 MCUs also take advantage of the Cortex-M0+ peripheral bus, allowing single-cycle access to the GPIOs. These features enable NXP LPC800 devices to offer deterministic, real-time performance - a key requirement for 8-bit developers.

LPC800 includes game-changing features, such as a switch matrix that enables designers to assign on-chip peripherals to any pin with a single line of code or a single click in the configuration tool. LPC800 serial peripherals are designed to be as lean as possible, making them more responsive and efficient. The new SPI can operate as a slave at frequencies independent of the processor clock, solving the common frustration of having to over-sample 4-to-n times the SPI just to receive data. This decoupling of the SPI and processor clock speed reduces power and simplifies the system design. The I²C has also been re-engineered to allow the LPC800 to lie and wait at near-zero power consumption, even without a system clock, and wake up upon an address match.

New! Embedded Artists LPC812 MAX Experiment Kit has been created as a guided tour to learn embedded programming with the mbed framework and the NXP's LPC800 microcontroller family with Cortex-M0+ cores. The experiments are performed on a breadboard for maximum flexibility and ease of use.

Smartphone Quick-Jack Solution

NXP ARM LPC800 Smartphone Quick-Jack Solution adapts the standard 3.5mm stereo audio jack found on most iOS or Android smart devices into a self-powered data port and provides a universal interface for external sensors, switches, and other external devices. This flexible solution gives both consumer and industrial product designers a simple, plug-and-go way to get data into an endless variety of control, monitoring, data collection, maintenance, medical, and entertainment applications. The Smartphone Quick-Jack Solution includes a small PCB with an NXP LPC812 microcontroller, an energy harvesting IC, a miniature joystick, and an expansion header.

LPC812 is an ARM Cortex M0+ MCU that manages the data transport, encoding/decoding data using the Manchester algorithm to be exchanged over the audio channels. The board's expansion header makes it easy to connect myriad sensors (such as temperature, humidity, wind, heart rate, and accelerometer), switches (lights and power), HMI devices (keyboards and game controllers) or other devices that collect or log data from a variety of sources.

An energy harvesting circuit utilizes the right audio channel to draw power from the smart device to power the Quick-Jack board and attached sensors. The onboard joystick can be used to demonstrate a UI implementation, with results displayed by an application on the connected smartphone or tablet. The supplied example App for Android phones and iPhone displays joystick position and temperature and can turn devices on the Quick-Jack board on and off.
