Eying wearable low-power health-tracking devices, the TC35670FTG low-power IC supports Bluetooth Low Energy (BLE) and NFC Type 3 Tag functions. The chip hits a peak power consumption of 5.9 mA for Bluetooth communication at 3.3V/-4-dBm transmitter output power or receiver operation and 600 µA or lower for NFC Tag communication at 3.3V. In deep sleep, power consumption is 0.1 µA at 3.3V. The Bluetooth component specifies a receiver sensitivity of -92.5 dBm and a transmitter output power between 0 dBm to -20 dBm in 4-dB steps. It supports Generic Attribute Profile (GATT) including client and server functions and host-based and stand-alone systems. Other features include a dc/dc converter, low-drop regulator, general-purpose ADC, user-program function, wake-up signal for the host device, and a PWM function. The TC35670FTG is available in a QFN40 package measuring 6 mm x 6 mm x 0.5 mm with an operating temperature range from -30°C to +85°C. Samples and mass production are available now and starter kits plus software deployment packages will be available later this month.
