ML7275

2.4GHz Band
IEEE802.15.4
ZigBee®RF4CE

Single-chip LSI equipped with ZigBee® RF4CE network protocol. Since it is provided with 8x8 key scan function and user program area (2KByte), a remote control application can be composed in single-chip.

ML7266

2.4GHz Band
IEEE802.15.4

Achieved 50% reduction of operating current compared with the conventional products(ML7065).

ML7246

2.4GHz Band
IEEE802.15.4

Possible to compose IEEE802.15.4 USB dongle in single-chip.

ML7222

2.4GHz Band

A long-term battery lifetime has been achieved by a low data-transfer speed and low power consumption. Moreover, the miniaturization of the module and the BoM cost reduction are achieved by built-in MCU.

 

Applications

The key word demanded to LSI for the spread of the RF remote control to various consumer electric appliances is "Low power consumption.
LAPIS Semiconductor's LSI/module for RF remote control having feature of low power consumption of the world top level can be used for remote control of various consumer electric appliances.




• Advantage by achieving remote control by wireless communications

• Omnidirectional:
ex) Possible to control without facing remote control toward the equipment
ex) Possible to control beyond rooms
• Two way communication:
ex) Information on the equipment can be transmitted and displayed to remote control.
ex) Remote control search: The lost remote control can be found by sounding directed by equipment.

World of RF Remote Control

• In case of Air Conditioner
All families can go out without anxiety. RF remote control makes possible to confirm the air conditioners status in all rooms and turn off them by one click.




• In case of Lightings
While watching TV with all families, it is easy to confirm the status of lightings of all rooms and turn off them.

 


Feature of Wireless Communication Network IEEE802.15.4 standard
IEEE802.15.4 achieves wireless communication with lower power consumption than wireless LAN and Bluetooth.
ZigBee is software that offers the wireless network constructed by using wireless communications of IEEE 802.15.4.



• ZigBee/IEEE802.15.4: the longest battery life!
