LAPIS Semiconductor offers lineup of LSI which can be used for radio station for telemeter, telecontrol, and data transmission with UHF radio communication.
They are ideal for data collection and device control applications by wider communication area than 2.4GHz by wireless property of less than 1GHz and wireless communication with circumvention property against shielding.
LAPIS Semiconductor is giving high priority to the quality and provides the solutions to satisfy the regulations and various specifications.

Compliant

Features

426MHz/429MHz transmission/reception LSI.
Compliant to STD-30 and STD-T67.

Useful to 2 systems of 426MHｚ/429MHz.
By the built-in functions such as data comparison function,
reduces the MCU load and contributes to saving power of the total system.

426MHｚ transmission LSI
(Capable 315-450 MHz operation)

Transmission only LSI

ML7396
series

920/950MHｚ transmission/reception LSI
(Capable 750-1,000MHz operation)

Supports the packet mode of IEEE 802.15.4 d/g.
Possible to manage the system by 20mW.

• Smart-meter/Telemeter applications
  Its low power consumption and ability of long distance communication enables telemeter applications.
  If meters (Gas or Electric etc.) have an unit with UHF communication technology, meter readers can gather data
  of each unit without visiting the actual units.
  This technology is also applied to telemetering vending machines or observing units used for weather forecasts.
• Home and building security
  Security systems such as lock control, fire alarm, trespass detection/report system applies UHF technology.
• POS and payment terminals
  Unwires handy terminals used by restaurants, stores, home delivery services, and other sectors.
