Embedded microcontrollers are essential to numerous daily applications. A modern example of this is the Microchip Technology Inc. ‘LPC11U34FBD48/421’ product series. This low-power, high speed, microcontroller provides an efficient way for manufacturers to embed intelligence into their products. Its aim is to provide features, performance and flexibility that can be easily incorporated into a wide range of applications. In this article, we will look at the application field and working principle of the LPC11U34FBD48/421.

Application Field:

The LPC11U34FBD48/421 was designed with a wide range of applications in mind. These applications can be divided into four main categories:

• Automotive
• Industrial
• Household
• Medical

The automotive industry has been quick to adopt the LPC11U34FBD48/421, finding uses for it in areas such as electronic stability and traction control systems, electronic fuel injection, airbag systems, and immobilizer systems. In industrial settings, the benefits of this microcontroller have been harnessed for controlling production machines, automated warehouses, monitoring systems, and robotic arms. On a smaller scale, the LPC11U34FBD48/421 finds use in domestic appliances such as washing machines, ovens, TVs, air conditioners, and refrigerators. Lastly, the combination of the robust design and powerful processing capabilities of the microcontroller make it well-suited for use in medical applications such as patient monitoring, diagnostic equipment, and life-support systems.

Working Principle:

The basic principle behind this microcontroller is fairly simple. It makes use of internal memory, timers, and input-output pins to interact with the environment and carry out basic computing tasks. The first central function is the processor, which can be one of two ARM Cortex M0 cores, the M0+ and the M3, with preset clock frequencies of 20MHz and 80MHz respectively. This is then combined with internal SRAM and Flash memory, typically between 256Kb and 1Mb. The total weight class for the device is between 8Kb and 64Kb, making it very small but also fast and energy-efficient. Also included are internal DMA, SPI, I2C, ADC and UART modules, for interfacing with external peripherals such as sensors or motors.

To communicate with the outside world, the microcontroller has several input-output pins. These pins can be used to dictate how the device behaves, as well as provide the results of its calculations. They can also be used to monitor the external environment and detect changes. For instance, input pins can be used to sense simple temperature signals or more complex movements, while output pins can be used to trigger relays or drive motors.

The overall power consumption of the LPC11U34FBD48/421 is also fairly low, generally between 20mA and 100mA. This is mainly down to its fast operation, its efficient memory subsytem, and its low idle current of just 750nA. As a result, it can be easily integrated into a wide variety of applications with minimal impact on battery life.

Conclusion:

The LPC11U34FBD48/421 is a powerful and versatile microcontroller that is well suited for a wide range of applications. Its low power, high speed, and robust design make it an ideal choice for manufacturers looking to incorporate intelligence into their products. Its combination of input-output pins, data processing capability, and low power consumption make it an optimal solution for many use cases.
