ULP wireless system-on-chip
The nRF51822 is a powerful multi-protocol single chip solution
for ULP wireless applications. It incorporates Nordic’s latest
best-in-class performance radio transceiver, an ARM Cortex M0
CPU and 256/128kB flash + 16kB RAM memory. The nRF51822
supports
Bluetooth
® Smart and 2.4 GHz protocol stacks.
Lower power and higher performance
The nRF51822 uses the 32-bit ARM Cortex M0 MCU, together with
extensive flash availability, 256/128kB in total with 40kB-180kB
available for application development. Code density and execution
speed are considerably greater than for 8/16-bit platforms. The
Programmable Peripheral Interconnect (PPI) system provides
a 16-channel bus for direct and autonomous system peripheral
communication without CPU intervention. This brings predictable
latency times for peripheral to peripheral interaction and power
saving benefits associated with leaving the CPU idle. The device
has 2 global power modes ON/OFF, but all system blocks and
peripherals have individual power management control which
allows for an automatic switching RUN/IDLE for system blocks
based only on those required/not required to achieve particular
tasks.
The new radio forms the basis of the nRF51822’s performance.
The radio supports
Bluetooth
Smart and is on air compatible
with the nRF24L-series products from Nordic Semiconductor.
Output power is now scalable from a maximum of +4dBm down
to -20dBm in 4dB steps. Sensitivity is increased at every level
and offers sensitivity ranges (dependent on data rate) from -96 to
-85dBm, with -93dBm for
Bluetooth
Smart.

nRF51822 Product Brief Version 2.3
The S-series protocol stacks complement
the nRF51 series SoCs. All nRF51 series are
programmable with software stacks available
from Nordic Semiconductor. This brings
maximum flexibility to application development
and allows the latest stack version to be
programmed into the nRF51 series SoC.

ANT multi-protocol SoC
Easy, fast and safe code development
The nRF51822 offers developers a clean separation between
application code development and embedded protocol stacks. This
means compile, link and run-time dependencies with the embedded
stack and associated de-bugging challenges are removed. The
Bluetooth Smart stack is a pre-compiled binary available from
Nordic Semiconductor, leaving application code to be compiled
stand-alone. The embedded stack interface uses an asynchronous
and event-driven model removing the need for RTOS frameworks.
OTA DFU
The nRF51822 is supported by a Over The Air Device Firmware
Upgrade (OTA-DFU) feature. This allows for in the field updates of
application software and SoftDevice with the S110 SoftDevice.
Maximum re-use and easy migration
The devices in the nRF51 series are pin compatible enabling
migration between technologies such as Bluetooth Smart and
ANT with no layout changes. The common HW architecture
ensures that one codebase can be re-used effortlessly between
nRF51 series devices. Variants in the nRF51 series enable simple
choices tailoring device selection to desired wireless protocol and
feature requirements with little or no changes.
