6/27/2023 0 Comments Segger embedded studio nrf51822The nRF51822 is available in a 6圆mm 48-pin QFN package and a 3.5×3.8mm 64-ball Wafer Level Chip Scale Package (WLCSP). It supports the S110 Bluetooth Low Energy and 2.4GHz protocol stacks (including Gazell), both of which are freely available in the nRF518 Software Development Kit. A flexible 31-pin GPIO mapping scheme makes it possible to achieve complete design flexibility as well as pin location and function. The nRF51822 also has a wealth of analog and digital peripherals that allow for interaction through a Programmable Peripherals Interconnect (PPI) system without CPU involvement. The embedded 2.4GHz transceiver supports Bluetooth Low Energy and 2.4GHz operation, with the 2.4GHz mode being wirelessly compatible with Nordic Semiconductor’s nRF24L series. The nRF51822 is built on a 32 bit ARM® Cortex™-M0 CPU with 256kB flash + 16kB RAM. The nRF51822 is a powerful, ultra-low-power, multi-protocol wireless system-on-chip (SoC), ideal for Bluetooth low energy and 2.4GHz ultra-low-power wireless applications. In IDLE mode, the current of nRF51822 is 2.6uA, the current of nRF51802 is 3.0uA, the standby current is different.The nRF51822 wake-up time is 4.4uS, while the nRF51802 wake-up time is 7.7uS. The internal wake-up time is different.The same transmit power consumes different currents, and nRF51822 saves more power. In the case of OdBm power supply: nRF51822 transmits current 9.7mA, nRF51802 transmits current 10mA. This leads to different power consumption of the chip’s transmission, and the power consumption of nRF51822 is lower.
