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


The TC35676 is a highly integrated RFCMOS Bluetooth device with built-in 192K Flash ROM, which supports the new Bluetooth Low Energy (BLE) 4.1 standard. TC35676 is suitable for ultra-low power portable products. The device comes with embedded BLE  stack and GATT profile. Toshiba has tested the Bluetooth interoperability extensively and performed Bluetooth Qualification Expert (BQE) qualification.

Key Benefits

  • Flexible system architectures through:
    • Embedded Bluetooth profile model (API over host UART)
    • Stand alone model (with embedded Bluetooth stack and profile, no host needed)
  • 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
  • QFN40 package allows small and cheap form factor designs

TC35676 Features

  • Bluetooth Low Energy (BLE) 4.1 compliant
  • Supports BLE GAP central and peripheral mode
  • Embedded 192KB Flash Memory and internal RAM for application code, data patches
  • On-chip balun, antenna switch, LNA, DC-DC converter
  • Operational Voltage: 1.8V to 3.6V
  • BLE peak power consumption: 5.9mA (depends on selected clocking scheme and data mode)
  • Deep sleep mode: 0.1µA; sleep mode 5µA
  • Peak current in operation mode: 5.9mA
  • Transmitter Output Power: 0dBm to -20dBm (4dB steps)
  • RX Sensitivity: -92.5dBm (typ.)
  • Operating Temperature Range: -40°C to 85°C
  • Package: 40pin QFN 6mm x 6mm 0.5mm ball pitch or 5mm x 5mm 0.4mm ball pitch, height 0.9mm
  • Profiles: GATT (Generic Attribute Profile), including server and client functions
  • Interfaces: UART (2), SPI & I2C interface, PWM output (3channels), ADC (4 channels),
    15 programmable IO
