Overview

The LPC845M301JBD48E is an entry-level 32-bit Arm Cortex-M0+ microcontroller designed for low-power applications requiring a small footprint and flexible I/O. It operates at up to 30MHz and features 64KB of flash memory, 16KB of SRAM, and a dedicated switch matrix for flexible pin mapping. This MCU is particularly suited for basic control tasks and user interface management with its integrated capacitive touch interface.

Why Choose This Part

The standout feature is the Switch Matrix, which allows designers to assign any peripheral function to nearly any pin, greatly simplifying PCB routing. It also includes a FAIM (Fast Access Initialization Memory) to configure the device immediately at power-on without waiting for flash initialization.

Applications

Capacitive Touch Interfaces
Utilizes the integrated hardware capacitive touch module to implement touch buttons or sliders in consumer electronics.
Sensor Hubs
Acts as a low-power aggregator for environmental or inertial sensors using I2C and SPI interfaces before waking a main processor.
Battery-Powered Handhelds
Optimized for longevity in portable devices with power-down modes as low as 10uA and sleep current of 320uA.
