NXP Semiconductors LPC82x 32-bit Arm® Cortex®-M0+ MCUs

NXP Semiconductors LPC82x 32-bit Arm® Cortex®-M0+ MCUs are designed for higher integration over the LPC81x, with a larger memory footprint that doubles maximum flash and SRAM size. The LPC82x offers three select peripherals to ease the transition into the 32-bit space. Furthermore, the switch matrix allows users the flexibility to map pins accordingly to simplify component routing on a PCB.

The NXP LPC82x MCUs feature a SCTimer, which can be configured to generate a variety of timing or PWM waveforms without the intervention of the CPU. To simplify serial communication requirements, the pattern match engine can be configured to generate interrupts from user-configurable Boolean operations on its eight pins. The LPC800 series shares critical pinouts through the range of subfamilies and packages, and customers can easily swap or scale packages and subfamilies as required.
