Overview

The LPC1114FBD48/301,1 is an entry-level ARM Cortex-M0 microcontroller designed for low-power applications requiring a 32-bit architecture. It operates at speeds up to 50MHz and features 32KB of flash memory alongside 8KB of RAM in a 48-LQFP package. This MCU is particularly notable for its 5V tolerant I/O and low power consumption, making it a bridge between traditional 8-bit systems and modern 32-bit platforms.

Why Choose This Part

It provides a significant performance boost over 8-bit and 16-bit microcontrollers while maintaining a very low power profile, consuming only 1.4mA at 12MHz. The integration of 42 I/O pins in a 7x7mm LQFP package provides high connectivity density for compact designs.

Applications

Battery-Powered Sensors
Utilizes deep power-down modes (0.22uA) and 1.8V to 3.6V supply range for long-term operation on coin cell batteries.
Legacy 5V Logic Interfacing
The 5V tolerant I/O pins allow direct connection to older digital systems and industrial sensors without external level shifters.
Industrial Control Nodes
Features a 10-bit ADC, UART, and SPI to manage local data acquisition and communication tasks in automation environments.
