ULP wireless System-on-Chip
The nRF52832 is a powerful multiprotocol single chip solutions
for ULP wireless applications. It incorporates Nordic’s best-in-
class performance radio transceiver, an ARM® Cortex™ M4F CPU
and 512kB flash and 64kB RAM memory. The nRF52832 supports
Bluetooth® low energy (Bluetooth 5), ANTTM and 2.4GHz proprietary
protocol stacks. The device also has a NFC-A tag interface for
OOB pairing.
Lower power and higher performance
The nRF52832 uses the 32-bit ARM Cortex M4F MCU, together
with extensive flash availability, 512kB in total with 400kB
available for application development. Code density and execution
speed are considerably greater than for 8/16-bit platforms.
Having HW support for DSP instructions as well as for Floating
point operations positions the Cortex M4F above Cortex M0/M0+/
M3 and M4 performance wise. The Programmable Peripheral
Interconnect (PPI) system provides a 20-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 is designed to support the Bluetooth 5 2Mbs
mode. This means the nRF52832 can be qualified for Bluetooth
5 applications. It supports Bluetooth low energy (Bluetooth 5),
ANT and proprietary 2.4GHz applications. It is on-air compatible
with nRF5x and nRF24x devices. Output power is programmable
between +4dBm and -20dBm and has receiver sensitivity of
-96dBm for Bluetooth low energy 1Mbs).

nRF52 DK Development kit for Bluetooth low energy, ANT
and 2.4GHz applications
The NFC module supports NFC-A tags with proximity detection
and Wake-on-field from low power mode. The NFC enables Out-
Of-Band Bluetooth pairing of devices and thus greatly simplifying
deployment.
Easy, fast and safe code development
The nRF52832 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 low energy and ANT 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 nRF52832 is supported by an Over-The-Air Device Firmware
Upgrade (OTA DFU) feature. This allows for in the field updates of
application software and SoftDevice.
Maximum re-use and easy migration
The nRF52832 have binary compatible peripherals with the nRF51
Series for most functions enabling easy migration between older
parts and the new nRF52 Series. The backwards compatibility of
most interfaces and the common SW architecture of the nRF51
Series S130 and the nRF52 Series S132 SoftDevices ensures that
existing codebase for the nRF51 Series can in very large parts be
re-used effortlessly on the nRF52 Series.
SoftDevices
The Nordic protocol stacks are known as SoftDevices and
complement the nRF52 Series SoCs. All nRF52 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 nRF52 Series SoC.
Development tools
Nordic Semiconductor provides a complete range of hardware and
software development tools for the nRF52 Series devices.
