 There are even stripped down 4-bit mask-programmable microcontrollers designed only for remote control use (such as NEC's μPD612xA (discontinued), μPD613x, μPD1724x, μPD6x; and μPD17932x 8-bit family).These offer keyboard wake, low power standby modes, and sample controller code though similar features are present on more general PIC microcontrollers or Atmel AVRs.Some infrared wireless laptop keyboards and mice use protocols similar to consumer IR devices.
