EMSi5340’s dual-core processor with Nordic Semiconductor's nRF Connect SDK allows the wireless connectivity to run on one core and the applications to operate on the second core. Additionally, its full speed USB and RS232/UART provide options for wired connectivity. EMSi5340 comes with advanced security like trusted execution, root-of-trust and secure key storage security features apart from increased memory. 

The state-of-the-art Arm CryptoCell-312 provides hardware-accelerated cryptography; and together with the key management unit (KMU) peripheral, root-of-trust and secure key storage are implemented. The security support and the multi core architecture make the nRF5340 the top-of-the-line of the Nordic Semiconductor line when compared to the nRF52832, nRF52840 or the nRF53833. The product’s hardware components such as 32KHz crystal and components for DC-to-DC power supply reduce power consumption.


EMSi5340 can be powered over USB, external 5V power or from a CR2450 battery, with additional battery options for larger capacity and recharge capability as per customer requirements.
