NXP USA Inc.
ARM® Cortex®-M0 LPC1100L Microcontroller IC 32-Bit 50MHz 32KB (32K x 8) FLASH 28-DIP
Active46,683 in stock

Overview

The LPC1114FN28 is a unique 32-bit ARM Cortex-M0 microcontroller housed in a 28-pin plastic DIP package. Operating at up to 50MHz with 32KB of FLASH and 4KB of RAM, it provides a powerful upgrade path for applications traditionally using 8-bit or 16-bit DIP microcontrollers. It is one of the few modern ARM processors that can be used directly on a breadboard without an adapter.

Why Choose This Part

The primary advantage is the 28-pin DIP form factor, which eliminates the need for SMT breakout boards during development. It offers a low power supply range of 1.8V to 3.6V while maintaining a high clock speed of 50MHz and providing standard serial interfaces like I2C, SPI, and UART.

Applications

Breadboard Prototyping
Ideal for students and engineers who need to prototype 32-bit ARM systems quickly on a standard solderless breadboard.
Legacy DIP System Upgrades
Provides a high-performance 50MHz drop-in replacement for older 8-bit DIP-based industrial control boards.
Educational Platforms
Used in university labs to teach ARM architecture and C programming without requiring surface-mount soldering skills.

Getting Started

Developers can use the MCUXpresso IDE or Keil MDK for software development alongside a standard CMSIS-DAP or J-Link debugger. Since this is a DIP part, it can be powered and programmed easily on a breadboard using a 3.3V LDO and a basic USB-to-Serial adapter for ISP (In-System Programming) mode.
