An embedded microcontroller is a computer which contains a processor, memory, and are designed to carry out certain tasks like controlling peripheral devices, memory management or communication protocols.They are used in a broad range of industries and electronic devices, ranging from cars to manufacturing control systems as well as home appliances.The LPC11A14FHN33/301 is a microcontroller for embedded applications based on a Cortex-M0 processor.It has a 32-bit ARM Cortex-M0 processor core running with its specific 32-bit power saving instructions. It includes one hundred and twenty kilobytes of on-chip Flash memory, six kilobytes of SRAM memory and twenty-two 16-bit programmable timers. It also includes two USARTs, four SPI/SSP ports with four-multiplexed I/O for each, as well as two I2Cs and an ADC. The LPC11A14FHN33/301 is designed to enable low cost and low complexity embedded systems.It offers a low system cost and a small size solution for a variety of embedded applications.It is a suitable solution for applications such as those in industrial, automotive and consumer products. It is well suited for cost-sensitive applications requiring a balance of performance, power efficiency, integrated features and low cost.Its application fields include industrial automation and motion control systems, home appliances, automotive accessories and control, medical instrumentation, consumer electronics and power control systems. This microcontroller also has a wide range of features designed to support a variety of applications such as real-time clock and Ethernet support for communication, hardware security for cryptography and secure boot, fault tolerance for reliable operation, low-power modes for energy efficient applications, and advanced power management. The LPC11A14FHN33/301 is a processor with a bus architecture and peripherals configuration. It provides two 8- bit parallel ports for direct connection to external hardware, such as LED displays, switches and D/A converters. These ports can also be used for serial communication, either RS-232 or other standard serial protocols. It also includes five 16- bit timers, USARTs, and a universal asynchronous receiver-transmitter (UART) port.The working principle of the LPC11A14FHN33/301 is that the user program is first uploaded to the on-board flash memory, and then the processor will execute the instructions in it.It reads and executes one instruction at a time in a sequential manner and performs the operations accordingly. The processor is also connected to memory, I/O ports, analog and digital devices, and communication interfaces, so that it can exchange and manipulate datawith these components. The microcontroller’s instruction set is optimized for common tasks found in embedded devices. For example, the microcontroller includes three clock and data recovery units, four peripheral control units, seven external bus interfaces, a multiplication and division unit and one hundred and forty-eight interrupt lines. In addition, it has an integrated Direct Memory Access (DMA) controller to improve performance.This microcontroller also has several power savings features, such as an idle mode, allowing the processor to turn off parts of itself and enter a low-power sleep state until the next interrupt is generated. When this occurs, the processor jumps back to the interrupt handling code, then goes back to sleep or to an alternate low-power mode. This helps to improve power consumption, making it a good choice for portable embedded devices.In conclusion, the LPC11A14FHN33/301 microcontroller is a low cost, low complexity embedded solution for a variety of applications. Its optimal instruction set and low power consumption together with a variety of peripherals, make it a suitable choice for industrial, automotive and consumer products.
