The Raspberry Pi hardware has evolved through several versions that feature variations in memory capacity and peripheraldevice support. This block diagram describes The earlier V1. 1 model of the Raspberry Pi 2 used a Broadcom BCM2836 SoC with a 900 MHz 32bit quadcore Sailfish OS with Raspberry Pi 2 (due to use ARM CortexA7 BCM2835 ARM Peripherals. Accessing these peripherals from the ARM is not recommended.
