The LPC2103/4/5/6 family of microcontrollers from NXP Semiconductors is specially targeted for embedded systems. It is a member of the ARM7 TDMI family, the core being the ARM7TDMI-S processor. It is manufactured with a low-power CMOS process and includes an on-chip memory, ARM Cortex-M3 processor and Ethernet controller. These microcontrollers come with a number of built-in peripherals such as USB, Ethernet, UART etc. and are designed to meet the requirement of various embedded applications.

The LPC2104FBD48/01 device is a single-chip microcontroller based on the ARM7TDMI-S cortex processor. This device is available in 48-pin (LPC2104FBD48/01) BGA package and it has embedded 64KB of on-chip high-speed Flash. This device consists of several general-purpose I/O ports, Serial Peripheral Interfaces (SPI), universal Synchronous/Asynchronous Receiver/Transmitter (USART), and other peripherals. It is specially designed for applications that require high performance and low power consumption.

Application Fields

The LPC2104FBD48/01 device is suitable for a variety of applications such as home appliance and automotive electronics, industrial control, security systems, medical electronics and audio/video applications. The device is also suitable for power management applications such as switching mode power supplies and renewable energy systems like solar and wind systems. The core architecture and peripheral functions also make it suitable for use in networked and computing devices as well as wireless communication applications.

The device offers great features such as 64KB Flash, 8KB RAM, 10-bit ADC, 8-channel PWM and 24 I/O ports to help embedded designers implement various applications more effectively. Its power management and low power friendly features make it suitable for battery powered applications. It is also suitable for low cost applications that require performance and low cost.

Working Principle

The LPC2104FBD48/01 microcontroller is primarily designed to be used in power sensitive applications, and is able to work efficiently in both active and sleep mode. When the device is in active mode, the CPU core is clocked and the peripherals are available to run specific tasks or code. The operating frequency of this device is up to 72MHz and can consume only 1.3mA/MHz current. This gives the device great flexibility for the application to be optimized for low power consumption and still maintain sufficient performance.

On the other hand, when the device needs to reduce power consumption, it can enter the sleep mode. This mode dramatically reduces the device’s current consumption. In order to reduce the power consumption further, the device can also enter the deep sleep mode, where only the power-on-reset feature is enabled and most of the device is powered down, including the clock and peripherals.

The LPC2104FBD48/01 microcontroller also provides several on-chip memory blocks such as ROM, RAM, Flash and cache, while external peripherals such as SD card and USB can be added to extend its capabilities.

The microcontroller provides a range of power management features such as Power-on Reset (POR), High Speed Clock (HCLK), Supply Voltage Supervisor (SVSL) and External Clock Source (ECS). The POR enhances system reliability by providing robust reset detection during power transitions. The SVS monitors the system supply voltage and can generate an interrupt to indicate a brown-out or shutdown condition.

The LPC2104FBD48/01 microcontroller provides the performance, features and low power consumption required for many embedded applications. With its combination of on-chip memory, peripherals, and power management features, it is an ideal choice for a wide range of embedded designs.
