Bluetooth low energy/2.4 GHz RF System on Chip NRF51822-QFAC-R

The nRF51822 is a powerful, highly flexible multiprotocol SoC ideally suited for Bluetooth® low energy and 2.4GHz ultra low-power wireless applications.

The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU with 256kB/128kB flash + 32kB/16kB RAM for improved application performance.

The embedded 2.4GHz transceiver supports both Bluetooth low energy and the Nordic Gazell 2.4 GHz protocol stack which is on air compatible with the nRF24L series products from Nordic Semiconductor.

nRF51822 is available in 6x6mm 48-pin QFN packages and 3 ultra-compact wafer-level chip-scale packages (WL-CSP).

nRF51822 is now available as a thin WL-CSP variant measuring 3.83mm x 3.83mm with a height profile of just 0.35mm, and is drop in compatible with regular WL-CSP devices.
