AKM provides low power consumption and high-performance communication RF ICs by utilizing its high design capability with unique process technologies.

AKM's Bluetooth® Low Energy (BLE) transmitter IC has built-in proprietary algorithm software so that can achieve fast startup and low current consumption without micro controller code.

The BLE transmitter ICs include AK1594 for fixed data transmission applications such as indoor positioning and monitoring systems, and AK1595 for general-purpose data transmission applications such as sensor nodes.

BLE transmit-only IC for variable data transmission applications

AK1595

The AK1595 has been develped as a BLE transmitter IC for variable data transmission applications.

The BLE function can be realized by simply setting the data to be transmitted to the built-in register, making it ideal for applications that add the BLE function to existing microcomputers.

Applications:
General data transmission applications such as thermometers, weight scales, blood pressure monitors, toys, IoT data nodes

● Support BLE Transmitter Functionality

● Low Interval Power Consumption of 15nA by High-speed Operation

● Reduction of PCB Design Man-hours and BOM Cost

BLE transmit-only IC for fixed data transmission applications

AK1594

The AK1594 is a BLE transmitter IC with built-in EEPROM. The data set in the EEPROM can be transmitted intermittently, making it ideal for applications that transmit fixed data.

It can also offer security protection for advertising channel packet using the AES128 encoding.  The various switching actions control transmitter power, interval and powering the transmitter.

Applications:
Monitoring systems, Loss prevention devices, Employee attendance management, Information guidance to smartphones in shops or exhibitions

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

● Ultra-Low Power Consumption

● Encoded Data Prevent Interceptions
