Specifications:

1.What processor is nRF51822?

• The nRF51822 is a system-on-chip (SoC) device that integrates a processor, memory, and various peripherals. The processor in the nRF51822 is an ARM Cortex-M0 32-bit microcontroller, which is a low-power, high-performance processor designed for use in IoT devices and other embedded applications

2.What is the difference between nRF51822 and nRF52832?

• The nRF51822 and nRF52832 are both system-on-chip (SoC) devices from Nordic Semiconductor that integrate a processor, memory, and various peripherals. However, there are some differences between the two devices:
  • Processor: The nRF51822 uses an ARM Cortex-M0 32-bit microcontroller, while the nRF52832 uses an ARM Cortex-M4F 32-bit microcontroller, which is a more powerful processor with more advanced features.
  • Memory: The nRF52832 has more on-board memory than the nRF51822, including more flash memory and RAM, providing more storage space for application code and data.
  • Peripherals: The nRF52832 has additional peripherals compared to the nRF51822, including an integrated digital signal processor (DSP) for advanced audio processing, and a larger number of general-purpose input/output (GPIO) pins.
  • Wireless connectivity: Both devices support Bluetooth Low Energy (BLE), but the nRF52832 also supports other wireless protocols such as ANT and 2.4GHz proprietary, which the nRF51822 does not.

3.What is nRF51822 micro controller responsible for?

• The nRF51822 is a microcontroller that is responsible for controlling the various functions and peripherals of a device in which it is integrated. Its primary responsibilities include:
  • Executing user-defined code: The nRF51822's ARM Cortex-M0 processor is responsible for executing the application code that is programmed into the device. This code can perform a wide range of tasks, including controlling peripherals, sending and receiving data, and responding to user inputs.
  • Managing peripherals: The nRF51822 integrates various peripherals, such as general-purpose input/output (GPIO) pins, analog-to-digital converters (ADCs), and timers, and it is responsible for managing these peripherals. This includes configuring and controlling the peripherals, as well as receiving and processing the data from them.
  • Wireless connectivity: The nRF51822 is designed to support Bluetooth Low Energy (BLE) wireless communication, and it is responsible for managing this communication. This includes sending and receiving data over and well as managing the BLE stack and protocols.
  • Power management: The nRF51822 is designed to be low-power and is responsible for managing the device's power consumption. This includes controlling the power states of the various components and peripherals, as well as reducing the power consumption when the device is not in use.
