nRF51 Series Reference Manual
Version 1.1
The nRF51 series offers a range of ultra-low power System on Chip solutions for your
2.4 GHz wireless products. With the nRF51 series you have a diverse selection of
devices including those with embedded Bluetooth® low energy and/or ANTTM
protocol stacks as well as open devices enabling you to develop your own
proprietary wireless stack and ecosystem.
The nRF51 series combines Nordic Semiconductor’s leading 2.4 GHz transceiver
technology with a powerful but low power ARM® CortexTM-M0 core, a range of
peripherals and memory options. The pin and code compatible devices of the
nRF51 series offer you the most flexible platform for all your 2.4 GHz wireless
applications.

4.1.2 Memory types
The various memory categories can have one of the following memory types:
• Volatile memory (VM)
• Non-volatile memory (NVM)
Volatile memory is a type of memory that will lose its contents when the chip loses power. This memory
type can be read/written an unlimited number of times by the CPU.
Non-volatile memory is a type of memory that can retain stored information even when the chip loses
power. This memory type can be read an unlimited number of times by the CPU, but have restrictions on the
number of times it can be written and also on how it can be written. Writing to non-volatile memory is
managed by the Non Volatile Memory Controller (NVMC).
4.1.3 Code memory
The code memory is normally used for storing the program run by the CPU, but can also be used for storing
data constants that are retained when the chip loses power.
The code memory is non-volatile.
4.1.4 Random Access Memory (RAM)
RAM is normally used by the CPU program for temporary data storage, but it is also possible to run a CPU
program from RAM.
The RAM is volatile and always loses its contents when the chip loses power. The RAM may also lose its
contents when entering System OFF power saving mode. Whether the RAM contents are lost in system OFF
power saving mode is dependent on the settings in the RAMON register in the POWER peripheral.
The RAM size may vary between different devices.
The RAM is located from address 0x20000000.
4.1.5 Peripheral registers
The peripheral registers are registers used for interfacing to peripheral units such as timers, the radio, the
ADC, and so on.
