Overview

The LPC812M101JD20J is an entry-level 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at frequencies up to 30MHz. Part of the LPC800 series, it is designed to provide a low-pin-count, power-efficient alternative to 8-bit and 16-bit MCUs while offering modern peripheral support like a Switch Matrix for flexible I/O pin assignment.

Why Choose This Part

The device features a unique Switch Matrix that allows designers to map any internal peripheral to almost any pin, simplifying PCB routing. It offers excellent power efficiency with deep power-down currents as low as 5uA and includes 5V tolerant I/Os, which is rare for many modern 3.3V microcontrollers.

Applications

Sensor Hubs
Aggregating data from multiple environmental or industrial sensors using I2C and SPI interfaces.
Human Interface Devices
Managing simple button matrices, rotary encoders, and status LEDs in consumer electronics.
System Supervisors
Acting as a low-power management controller for larger SoCs, handling power sequencing and watchdog functions.
Legacy MCU Replacement
Upgrading 8051 or PIC-based designs to 32-bit performance while maintaining a small SO20 footprint.
