Toshiba Starts Sample Shipments of Low Power Consumption ICs for Bluetoo Smart Devices

February 25, 2014

Promoting Adoption of Communication Functions for Wearable Healthcare Devices

TOKYO Toshiba Corporation (TOKYO: 6502) today announced the launch of TC35667FTG, a low power Bluetooth IC that supports Bluetooth Low Energy (LE)[1] communications. Sample shipments start today.

Recently, the number of Bluetooth Smart[2] 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 FeaturesLow 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)
