Recently, the number of Bluetooth^® Smart² devices offering Bluetooth^® LE compatibility is growing. The new IC adopts an original low-power circuit design and integrates a highly efficient DC-DC converter, reducing peak current consumption to below 6mA and deep sleep current consumption to below 100nA. It promotes long life for small coin cell batteries and will facilitate adoption of Bluetooth^® LE communications for small devices, such as wearable healthcare devices, sensors and toys.

The IC also integrates an ARM^® processor, enabling download and execution of customer programs stored in EEPROM. It supports customization of applications, eliminating need for any external microcontroller.

Toshiba will expand the device line-up to include in automotive applications, supporting a wide range of Bluetooth^® Smart devices.

Key Features

• Low power consumption:
  • Less than 6mA at peak consumption (@3.3V, -4dBm Transmitter output power or Receiver operation)
  • Less than 100nA in deep sleep (@3.3V)
• Receiver sensitivity: -91dBm
• Supports Bluetooth^® LE central and peripheral devices
• Supports servers and client functions defined by GATT (Generic Attribute Profile）

Applications

Bluetooth^® Smart devices, such as wearable devices, healthcare devices, smart phone accessories, remote controllers, and toys.
