Design process for Raspberry Silicon outlined by engineer
st January at a price of just US$4. The Pico is a microcontroller - a device-class often paired with a more powerful computer for analogue input and low-latency I/O, and sometimes a very-low power standby mode. One of the most interesting things about the Pico was that it became the first product to feature 'Raspberry Silicon', in the shape of the RP2040, and on Monday one of the engineers tasked with making this first in-house processor design wrote a blog on the whole process, entitled The journey to Raspberry Silicon. The journey began in the summer of 2017. After deciding what fundamental...
