Toshiba has announced the launch of two Bluetooth ICs, that support Bluetooth Low Energy (LE) ver.4.1 communications. The TC35676FTG/FSG have built-in Flash ROM, while the TC35675XBG supports both Flash ROM and NFC Forum Type 3 Tag for peer-to-peer communication. Sample shipments of these devices 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].
These ICs are targered at 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.
