Toshiba's New ICs for Bluetooth® Smart Devices Feature Built-in Flash ROM, Will Promote Adoption of Communication Functions for Wearables

TOKYO--(BUSINESS WIRE)--Toshiba Corporation (TOKYO: 6502) today announced the launch of two Bluetooth^® ICs, that both support Bluetooth^® Low Energy (LE)^[1] ver.4.1 communications. The “TC35676FTG/FSG” integrates built-in Flash ROM, while the “TC35675XBG” supports both Flash ROM and NFC Forum Type 3 Tag for peer-to-peer communication. Sample shipments start today.

The “TC35676FTG/FSG” adds to the current “TC35667FTG/FSG” line-up launched last year. These devices realize low power consumption with an original low-power circuit design and integration of a highly efficient DC-DC converter. The new IC builds on these with the addition of Flash ROM to store user programs and various data for stand-alone uses. The new IC also has a 64KB user program area, achieved by increasing the internal SRAM size that allows its internal ARM^® processor to execute various kinds of application programs.

The “TC35675XBG” is an addition to the “TC35670FTG” line-up. Integrated into a product, its NFC Tag realizes easy Bluetooth^® peer-to-peer paring and easy power on/off functions simply by touching another NFC supported mobile device, extensions of the “TC35676FTG/FSG” functions.

The new ICs will boost cost performance, as the built-in Flash ROM eliminates any need for an external EEPROM and reduces external part counts and PCB size. They also have the same low power consumption feature as the current ICs and operate long operating times for applications powered by small coin cell batteries. For example, using a CR2032 type coin battery, the new ICs can carry out beacon operation for more than six months^[2].

The new ICs will facilitate adoption of Bluetooth^® LE communications for high grade small devices, such as wearable healthcare devices, sensors and toys, and will support set makers in optimizing product value.

Key Features
