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.
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)
