Overview

The LPC812M101JTB16X is an entry-level 32-bit ARM Cortex-M0+ microcontroller designed to provide high efficiency in a compact 16-pin XSON package. Operating at up to 30MHz with 16KB of Flash and 4KB of RAM, it serves as a modern replacement for 8-bit architectures in cost-sensitive applications. The device is notable for its flexible switch matrix, allowing engineers to map any peripheral function to any available I/O pin.

Why Choose This Part

The integrated Switch Matrix significantly simplifies PCB routing by allowing pin assignment flexibility on all 14 I/O pins. The inclusion of ROM-based drivers for I2C and USART reduces the code footprint in the 16KB Flash, while the ARM Cortex-M0+ core delivers 32-bit performance at power levels comparable to 8-bit MCUs.

Applications

I/O Expansion
Utilizing the flexible switch matrix to act as a smart bridge between legacy peripherals and modern processors.
Handheld Battery Devices
Taking advantage of the 170uA deep power-down mode for extended shelf life in portable consumer electronics.
Sensor Hubs
Managing local sensor data via I2C or SPI and using the boolean pattern-matching feature for interrupt-driven wakeups.
Simple Motor Control
Using the State Configurable Timer (SCTimer) to generate complex PWM waveforms for small BLDC or stepper motors.
