Raspberry Pi Releases BCM2835 Datasheet for ARM Peripherals

If you have been following Raspberry Pi project, you may have noticed the dearth of documentation related to Broadcom processors. For BCM2835 (The processor used in Raspberry Pi board), Broadcom only has one laconic webpage.

But the Raspberry Pi’s “super-team” has managed to get a (partial) datasheet for the SoC showing the details of BCM2835 ARM peripherals which is all that we may need. This would only be useful for people playing around with the Linux (and u-boot) drivers.

The document includes details about the processor’s memory map as shown below.

It also contains details (registers, implementation details, etc..) about the following ARM peripherals:

  • Timers
  • Interrupt controller
  • GPIO
  • USB
  • PCM / I2S
  • DMA controller
  • I2C master
  • I2C / SPI slave
  • SPI0, SPI1, SPI2
  • PWM
  • UART0, UART1

You can download BCM2835 datasheet to get the complete documentation.

The Raspberry Pi foundation also announced that the boards will be ready on February 20. After that, the boards will have to be airfreight to the UK, and should be available for purchase at the end of February.
