nRF5340 is a wireless ultra-low power multiple core System on Chip (SoC) integrating two fully programmable
Arm Cortex M33 processors, advanced security features, a range of peripherals, and a multiprotocol 2.4 GHz
transceiver. The transceiver supports Bluetooth low energy
.
The two Arm Cortex M33 processors share the power, clock, and peripheral architecture with Nordic
Semiconductor nRF51, nRF52, and nRF91 Series of PAN/LAN SoCs, ensuring minimal porting efforts. The
application core is a full-featured Arm Cortex M33 processor including DSP instructions and FPU and running
at up to 128 MHz with 1MB of flash and 512 KB of RAM. The option to run the application processor at 64 MHz
allows th eCPU to increase energy efficiency. The network core is an Arm Cortex M33 processor with a
reduced feature set, designed for ultra-low power operation. It runs at a fixed 64 MHz frequency and contains
256 KB of flash and 64 KB of RAM.
The peripheral set offers a variety of analog and digital functionality enabling single chip implementation of a
wide range of applications. Arm trustZone technology, Arm cryptoCell-312, and supporting blocks for ysytem
protection and key management are embedded for the advanced security needed for IoT applications.
