Bluetooth® Single-Chip Controller for Bluetooth Low Energy (4.1) + NFC Tag

The TC35670 combo device supports the new BT Low Energy (LE) 4.1 standard and includes an NFC Forum compliant  Tag Class 3. The NFC Tag can wake up the BLE device from sleep mode through the NFC antenna and initiate easy Bluetooth pairing after confirmation of the BT device address. This connection setup enables ease of use and a very long battery life. TC35670 is ideal for ultra low power portable products and comes with embedded BLE stack and GATT profile.  Toshiba Bluetooth® Silicon and Software Brochure (pdf 4.9MB)

Key Benefits

TC35670 Bluetooth LE (4.0) + NFC Tag
  • Shorten BLE host active period to further lower power to near 0
  • Bluetooth Low Energy (LE) 4.1 compliant
  • Flexible system architectures through:
    • Embedded profile model (API over host UART)
    • Stand alone model (with embedded stack and profile)
  • Low power NFC Tag function
  • Compliant with NFC Forum Tag Class 3 for easy pairing initialization and transfer of small amounts of data (ISO/IEC18092)
  • Supports wake up with 0 standby: when a remote device requests communication establishment the Tag block makes a wake up signal without host control and local battery consumption
  • On-chip EEPROM to store and transfer NFC data without host control
  • Bluetooth qualified embedded BLE stack and GATT profile for easy Bluetooth SIG EPL
  • On-chip RAM for simple to medium size application code and data
  • Supports over-the-air (OTA) update of system software
  • Ultra low bill of materials due to very few external components
  • System integration by various on-chip peripherals
  • Flexible single power supply (1.8V-3.6V)
  • Various sleep modes and clock options to optimize power consumption
  • Small and cheap system design with QFN40 package: 6mm x 6mm
