For selective NRF51822 and NRF52832 I believe we are very confused, which cost high? Here, we will tell a difference at NRF51822 and NRF52832, so that we can better develop products quickly to speed up the selection progress!
Divided into five main points:
First, power consumption: nRF52832 is simply on the basis of nRF51822 will reduce power consumption by half
Second, the RF better reflect, transmit power and mainly better receiving sensitivity. Transmission power, his brothers appropriate, are + 4dbm, nrf52832 sensitivity is -96dbm, nrf51822 receiving sensitivity is -93dbm.
Third, the more processing ability, nrf52832 processor M4F, Cortex-M4F increase a (floating point unit) Floating Point unit, floating point unit may be used superficial more computing requirements. nrf51822 selection is still Cortex-M0 core. Cortex-M0 core is a low-power core, other suitable sensor data is collected, less Cortex-M4F algorithm in operation.
Four, more RAM, and the Flash support, in terms of flash, nrf51822 128kb support and 256KB, and 512KB nrf52832 support; RAM area, nrf51822 support 16kb and 32KB, 64KB and nrf52832 support;
Five, nrf52832 support more protocols, nrf52832 support BLE, ANT, and free protocol 2.4Ghz NFC; nrf51822 support only BLE, ANT, free of 2.4Ghz protocol.
If the choice between these two chips, then certainly nrf52832 better than many; but considering the cost and functional requirements, if satisfied with the nrf51822 still choose nrf51822 better, after all, it is a very Nordic classic of a chip.
