nRF52832

ULP wireless System-on-Chip
The nRF52832 Preview is a powerful multiprotocol single chip solutions for ULP wireless applications.
It incorporates Nordic’s latest best-in-class performance radio transceiver, an ARM® Cortex™ M4F CPU and 512kB flash and 64kB RAM memory.
The nRF52832 Preview supports Bluetooth® Smart (formerly known as Bluetooth low energy), ANT 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 Preview 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 forms the basis of the nRF52832 Preview performance. The radio supports Bluetooth Smart and ANT and
is on air compatible with nRF24AP, nRF24L and nRF51 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 -89dBm, with -96dBm for Bluetooth Smart, and -92.5dBm for ANT.
