Why Do Some Microcontrollers Operate at 3.3V While Others Use 5V? Can’t We Standardize?

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
