PIC16F723A-E/SO is a 28-Pin Flash Microcontroller with XLP Technology. 8-bit microcontrollers have been around since the early 80s and have played a central role in modernizing electronics. Even though 8-bit microcontrollers will eventually get phased out, there is no sign of a reduction in 8-bit usage, and 8-bit microcontrollers are still highly relevant.
