Overview

The LPC1114FBD48/302,1 is an ARM Cortex-M0 based microcontroller designed for low-power 32-bit applications. Operating at speeds up to 50MHz, it provides 48KB of Flash and 8KB of RAM, offering a significant performance upgrade over traditional 8-bit and 16-bit architectures while maintaining high code density. The device features 42 I/O pins and a versatile peripheral set including I2C, SPI, and UART interfaces.

Why Choose This Part

This microcontroller offers a high I/O count of 42 pins in a compact 48-LQFP package, making it ideal for designs requiring many GPIOs. It supports a wide supply voltage range from 1.8V to 3.6V and includes built-in power management features like Power-On Reset (POR) and Brown-out Detect (BOD) to ensure system reliability.

Applications

Industrial Sensor Nodes
Utilizing the 32-bit processing power and low-power modes to process and transmit data from analog and digital sensors.
