These devices are suitable for use in products such as remote controllers, fan/light controllers, washing machine controllers, scales, toys, and various subsystem controllers. They all contain a halt feature to reduce power consumption. The major differences between these microcontrollers are attributed to variations in sizes of the ROM and RAM, as well as bit number, counter number, I/O line number, and different level subroutine nesting.
