ROHM Sensors

Wireless communication

These days, many devices around us are linked to other devices in a variety of ways, and this situation is only expected to expand in the future to meet the needs for lower costs, greater energy savings, and increased convenience.
In response, ROHM offers a wide variety of wireless communication solutions, including modules that integrate proprietary ICs, covering a broad range of frequencies from sub-GHz to 2.4GHz.

Specified Low Power Radio(Sub-GHz Band)

WQFN32

WQFN32

LAPIS Semiconductor's specified low power radio ICs are used in a wide range of applications, from telemetry and fire alarms to home security and industrial remote controllers. In addition, the ICs have been adopted in Smart Meters, which have seen increased proliferation in recent years. The broad lineup also includes models that support overseas specifications, and each IC undergoes strict quality control, allowing customers to develop products for receiving and transmission that comply with all relevant laws and regulations.

Features

Bluetooth® Smart Modules

MK71050-03

MK71050-03

LAPIS Semiconductor's Bluetooth® Smart modules are designed to be easier to use than conventional ICs. All peripheral components required for operation are incorporated, along with an antenna, while maintaining ultra-low power consumption. In addition, the modules have been certified not only under Japan's Radio Act, but by the FCC (US) and CE (EU) as well. Bluetooth® SIG End Product Certification has also been obtained, making it possible to develop embedded Bluetooth® Smart devices.

Features

  • Supports Bluetooth® Low Energy single mode
  • Bluetooth® Core Spec v4.0 compliant (MK71050-03)
  • Low current consumption ideal for coin/button batteries: 9mA during transmission/reception (MK71050-03)
  • Built-in LAPIS Semiconductor IC
  • Wireless transmission characteristics pre-adjusted before shipment
  • Radio Act/FCC/CE certified with integrated antenna (MK71050-03)
