Why Do Some Microcontrollers Operate at 3.3V While Others Use 5V? Can’t We Standardize?
Some may have noticed that the voltage standards for microcontrollers vary; some operate at 3.3V while others use 5V. Why isn’t there a unified standard? Is this a historical legacy issue or an inevitable result of technological evolution? Today, we will explore this question. 1. The Aftermath of the TTL and CMOS ‘Cold War’ The … Read more
