BLE Transmission IC

BLE transmit-only IC

Beacon solutions using Bluetooth® Low Energy, (BLE), are used in various applications such as monitoring systems, loss prevention devices, employee attendance management, and information guidance to smartphones in shops or exhibitions.  Adoption is expected to spread quickly.  However, in the past BLE bacon market, there were only BLE SoCs which support transmitter and receiver both, thus SoCs require tremendous software development.  A beacon solution with longer battery life can be easily designed with the AK1594, a transmit-only BLE IC.

A BLE beacon can be designed by writing the initial settings and transmission data to the internal EEPROM, since the AK1594 has no micro-controller and is a transmit-only device.  This reduces the development period of beacon systems compared to existing BLE ICs that integrate a micro-controller.  Moreover, the AK1594 achieves best in class low power consumption in the field and a maximum +6dBm (Typ.) output transmission.  The AK1594 offers security protection for advertising channel packet using the AES128 encoding.  The various switching actions control transmitter power, interval and powering the transmitter.


● Developing a Program is Not Necessary on a Device without a Micro-controller

A BLE beacon can be designed by just writing the initial settings and transmission data to the internal EEPROM.  A Complicated development environment, programing, and debugging are not necessary.

● Ultra-Low Power Consumption

It achieves 9.1uA* (Typ.) ultra-low power consumption, contributing to longer battery life of the device.

* Transmit Power: 0dBm, Advertising Interval: 1sec

● Encoded Data Prevent Interceptions

AES128 encoding is available.  This prevents tracking or cloning of the beacon.

  • Monitoring System for Children, the Elderly, and Pets,
  • Loss Prevention Devices,
  • Office and Factory's Indoor Positioning Systems,
  • Other IoT Products

Employee Attendance Management,  Monitoring System

Gateways located inside or outside a room can receive beacon signals.  A person with a beacon can be confirmed their attendance and the location.

Commodity Management,  Inventory Control

When a beacon is installed in a key or baggage, a smartphone or gateway receives the beacon signal and records the time and location.  A system for logistics management or loss prevention of important things can be built.

Coupon Distribution System

A coupon distribution system for stores can be realized.  Push notifications are sent to smartphone users in the receiving range of a beacon signal.
