Overview

The LPC812M101JDH20J is a 32-bit ARM Cortex-M0+ microcontroller designed as a high-efficiency alternative to legacy 8-bit and 16-bit MCUs. Operating at up to 30MHz with 16KB of flash and 4KB of RAM, it features a flexible switch matrix that allows peripheral functions to be assigned to any pin.

Why Choose This Part

The standout feature is the Switch Matrix, which simplifies PCB routing by letting designers assign any digital peripheral to any pin. It also includes ROM-based drivers for I2C and USART to save flash space and power profiles that optimize energy consumption down to 170uA in shutdown.

Applications

Simple Sensor Hubs
Utilizes the ARM Cortex-M0+ core and internal oscillator for low-power processing of environmental or industrial sensor data.
Human Interface Devices
Ideal for small keyboards or control panels where its 18 I/O pins and USART/I2C/SPI interfaces manage user input.
System Supervisory Controllers
Acts as a primary power or reset controller using the integrated brown-out detect and watchdog timer.
