As of 2019, the [https://www.nordicsemi.com/?sc_itemid=%7B2DC10BA5-A76E-40F8-836E-E2FC65803A71%7D nRF52840] is the most advanced SoC of Nordic Semiconductor's nRF52 line. The nRF52840 packs a 32-bit [[ARM]] Cortex-M4F at 64MHz with 1MB of NOR flash and 256KB of RAM accessible via its [https://en.wikipedia.org/wiki/Advanced_Microcontroller_Bus_Architecture#Advanced_High-performance_Bus_(AHB) AHB] ([https://en.wikipedia.org/wiki/Advanced_Microcontroller_Bus_Architecture AMBA]v2). 9 distinct AHB slaves are (non-uniformly) connected to memory, and 2 to flash (one to each of data and instruction cache). 3 SPI and 1 QSPI interfaces run at up to 32MHz.
