Toshiba Launches Low Power Consumption ICs for Bluetooth® Smart Communication Devices with NFC Tag functions

Incorporating Two Kinds of Communication Functions for Wearable Healthcare Low Power Devices

TOKYO — (BUSINESS WIRE) — September 24, 2014 — Toshiba Corporation (TOKYO:6502) today announced the launch of “TC35670FTG”, a low power consumption dual function IC that supports both Bluetooth® Low Energy (LE)[1] communications and NFC Type 3 Tag. Sample shipments start today.

Recently, more and more Bluetooth® Smart[2] devices offer Bluetooth® LE compatibility. The new IC joins Toshiba’s line-up of Bluetooth® LE ICs, and offer two key features: easy operation of Bluetooth® pairing with NFC Tag function; long-time stand-by status for devices powered by small coin-cell batteries. The IC will facilitate adoption of Bluetooth® LE communications in small devices, such as wearable healthcare devices, sensors, toys and, most notably, future touch and start smartphone accessories.

Previously, set makers had to integrate ICs for both Bluetooth® and NFC Tag when designing a system supporting both communication functions. Toshiba’s new approach offers a design that will help to minimize the part counts, reduce the assembly area by about 30% and shorten system development.

The NFC Tag component has a 1.5 Kbyte E2PROM for storing data that set makers can access using both the Bluetooth® LE and NFC Tag to connect each I2C interfaces, allowing data to be easily handled in each system.

These functionalities allow the new device to support three ways of use:
1.  

Put both Bluetooth® LE and NFC Tag in stand-by mode and prioritize the connection from the 1st access.

2. By adding NFC Tag function, easy pairing of Bluetooth® LE devices can be realized and a long time stand-by status can be maintained.
3. The NFC Tag can provide a system on/off switch function, and cut off the hardware switch from a lot of devices that are required to reduce stand-by power.
