PublishTime： 2021-12-09 Article Source：RF-STAR

nRF52840 SOC is the most advanced member of nrf52 series SOC family. It can meet the challenges of complex applications that require a rich and diverse set of peripherals and functions. It provides a large amount of available memory for flash and ram, which is a prerequisite for high demand applications.

nRF52840 fully supports multi protocol, including ble 5, Bluetooth mesh, thread, ZigBee, 802.15.4, ant and 2.4GHz proprietary protocol stack.

nRF52840 SOC is built around 32-bit arm^® cortex ™ - M4 CPU, with 64 MHz floating-point unit, which has sufficient general processing capacity, floating-point operation and DSP performance to meet the challenging wireless application requirements. It has nfc-a tags to simplify pairing and payment solutions. The arm TrustZone ® cryptocell encryption unit included on the chip provides a range of encryption options that are executed efficiently independent of the CPU.

nRF52840 has two packages: 7 x 7 aqfn73 with 48 gpios and 3.5 x 3.6 wlcsp94 with 48 gpios.

nRF52840 is an advanced and highly flexible single-chip solution, which is suitable for today's increasingly demanding ULP wireless applications, for our personal connection devices, connected living environment and the general Internet of things. It is designed to prepare for the major functional advances of ble 5 and to take advantage of the enhanced performance of ble 5, including remote and high performance. In today's applications, industrial level security is essential.

A wide range of peripherals can utilize many high-performance digital interfaces, such as high-speed SPI (32 MHz) and four-level SPI (32 MHz), allowing direct interface to displays and external storage sources. Nrf52840 can supply voltage from 5.5V to 1.7V, allowing direct power supply from rechargeable battery and USB power supply.

The modules using nrf52840 SOC chips have many applications, such as those developed by RF-Star，RF-BM-ND05 and RF-BM-ND06，It is widely used in wearable devices with wireless payment function, NFC payment, customized applications and so on, with more outstanding performance.
