Enhanced Security & Ultra-Low Current Single-Chip Controller for Bluetooth Low Energy (4.2)


The TC3567DFSG extends Toshiba's line-up of high-performance ultra-low power consumption devices supporting Bluetooth® Low Energy ver.4.2 communications and offering enhanced security functionality.  As the TC3567DFSG has no built-in Flash ROM it is able to achieve ultra-low power consumption while supporting longer operating times for applications powered by small coin batteries. The new IC will aid the adoption of Bluetooth® LE in IoT products requiring a high level of security, including wearable devices for healthcare applications and high-grade small devices that use coin batteries, such as sensors and toys.

Key Benefits

  • Flexible system architectures through:
    • Embedded Bluetooth profile model (API over host UART)
    • Host or stand alone mode are possible (with embedded Bluetooth stack and profile, external EEPROM needed for stand alone mode application code)
  • Bluetooth qualified embedded BLE stack and GATT profile for easy Bluetooth product qualification
  • Ultra-low bill of materials due to very few external components:
    • 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
  • Supports a multiple number of simultaneous master/slave connections
  • QFN40 packages allow small and cheap form factor designs

TC3567D Features
