The availability of low-cost 2.4GHz ISM band IEEE 802.15.4 wireless nodes has opened RF remote control applications in home TV and entertainment systems markets. The RF remote control application is most commonly built upon the Zigbee BeeStack Consumer (RF4CE) communication standard or Freescale's proprietary SynkroRF software platform. Freescale's BeeStack Consumer (RF4CE) or SynkroRF software stacks are most commonly used on 9S08 MCU based platforms:
• MC1321x-HCS08A MCU plus transceiver in a single 71-pin LGA;
• MC13202 transceiver used with MC9S08QE128 MCU.

As manufacturers make the transition from conventional IR-based remote controls to RF communication, it may be advantageous to continue to provide IR blaster capability along with the RF radio.

This application note provides some recommendations and guidelines for implementing an IR remote control blaster function on the above referenced HCS08-based MCUs.
