I may be a microcontroller guy myself, but there are times where you need the power of a microprocessor. Having an operating system handle the memory, peripherals and events just saves time, and some applications really do need the power a microprocessor provides.
Atmel’s SAMA5D3 family has some impressive devices. Based on ARM’s A5 architecture, they have an impressive amount of peripherals and I/O lines. To name just a few, the SAMA5D36 has 3 I2C ports, 6 SPI ports, 12 12-bit ADC channels, and something you don’t see every day, 7 UART ports. This is impressive enough, but to add to that, the SAMA5D3 also has up to 160 I/O pins, each with its own interrupt. The SAMA5 series is geared towards industrial environments, automotive devices, and with Atmel’s implementation of capacitive touch peripherals, it can be used on just about any application where a user must input data.
With all that power, it isn’t surprising that the German manufacturer emtrion used this processor for one of their development boards, the SBC-SAMA5D36. They not only went with the SAMA5D36 device for its power and reliability, but also for Atmel’s reactivity when it comes to support. Atmel has worked hard on Linux implementation, and so the Linux kernel has everything you need to access every part of the processor, but I’ll get into that later.
