Microprocessors for Embedded Systems
Embedded engineers and hobbyists now have an abundance of options when it comes to computing power, owing to the wide selection of microcontrollers available. However, this hasn't always been the case, so let's explore the history of embedded systems. David Ashton writes: "Intel started the ball rolling in 1974 with the venerable 8080, which could be said to herald the true start of the microprocessor age. It needed two support chips, the 8224 clock generator, and the 8228 bus controller. Unusual for today’s engineers, it also needed both ±5 V and +12 V supplies. Later iterations, such as the 8085, only needed a +5 V power supply." Read on to learn more.Download article
