Asahi Kasei Microdevices Develops Transmit-Only BLE IC

Asahi Kasei Microdevices Corp. (AKM) has developed the AK1594, a transmit-only Bluetooth Low Energy (BLE) IC that, according to the company, enables the design of beacon solutions with a longer battery life. Beacon solutions using BLE are utilized 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, the company reports.

A BLE beacon can be designed by writing the initial settings and transmission data to the internal EEPROM, since the AK1594 has no microcontroller and is a transmit-only device. This reduces the development period of beacon systems compared to existing BLE ICs that integrate a microcontroller.

Moreover, the company indicates, the AK1594 achieves low power consumption in the field and a maximum +6dBm (typ.) output transmission. The IC offers security protection for advertising channel packet using the AES128 encoding. Samples are available now. The AK1594 has been adopted to ultra-low power consumption beacons by Houwa System Design K.K., in Japan.
