Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order for them to operate together, the use of additional voltage translators was required, which made the device more complicated and increased the final price. Now, this is a thing of the past.
