TC35675

Bluetooth® Single-Chip Controller for Bluetooth Low Energy (4.1) With Built-In Flash ROM + NFC Tag

The TC35675 combo device supports the Bluetooth Low Energy (BLE) 4.1 standard, integrates 192KB Flash Memory 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 Bluetooth device address. This connection setup enables ease of use and a very long battery life. TC35675 is ideal for ultra-low power portable products and comes with embedded BLE stack and GATT profile.

Key Benefits

TC35670 Bluetooth LE (4.0) + NFC Tag
  • Allows the extension of battery lifetimes by supporting wake up with 0 standby current. The integration of an NFC Tag and Bluetooth LSI allows the Bluetooth circuit to be off until woken up by an active NFC controller signal from another device.
  • Easy pairing initialization and transfer of small amounts of data with NFC Forum compliant Tag
  • Exchange of data with NFC Tag EEPROM without waking up the Bluetooth circuit
  • Flexible system architectures through:
    • Stand alone model (with embedded Bluetooth stack and profile, no host needed)
    • Embedded Bluetooth profile model (API over host UART)
  • Bluetooth qualified embedded BLE stack and GATT profile for easy Bluetooth product qualification
  • Ultra-low bill of materials due to very few external components:
    • No external memory is needed, on-chip Flash and RAM stores small to medium size application code and data
    • System integration is simplified by various on-chip peripherals
    • Only a small RF circuit is necessary due to built-in discrete components
  • Supports over-the-air (OTA) update of system software
  • The device can operate at voltages between 1.8V and 3.6V making it suitable for use with various battery types such as coin cell, AAA, or AA
  • Various sleep modes and clock options to optimize power consumption
  • FBGA52 package allows small form factor designs
