Bluetooth® 5.0 ICs realize high-performance, long range and low power
Toshiba Electronics Europe has added the TC35680FSG and TC35681FSG to its line-up of ICs compliant with the Bluetooth® low energy Ver. 5.0 communications standard. The ICs enable the high-speed features 2M PHY and Coded PHY (500 kbps and 125 kbps) added to the Bluetooth Ver. 5.0 standard and support all of the required data rates.

Receiver sensitivity is an industry leading -105 dBm at 125 kbps, and a built-in high efficiency power amplifier in the transmission block delivers up to +8 dBm transmission power. All these features enable long range communication with low current consumption.

Based on an ARM® Cortex®-M0 processor, the ICs incorporate a 256 kB Mask ROM that supports the Bluetooth baseband process, and 144 kB of RAM for processing Bluetooth application programs and data. They support both the HCI and GATT profiles, including server and client functions.

Additionally, 18-port GPIOs interfaces, which can be set to 2 channels each for SPI, I2C, and UART are also included, allowing full structuring of systems that connect to various peripheral devices. These GPIOs can be configured as a wakeup function, 4-channel PWM, 5-channel ADC interface and many others. They can optionally be configured as a control interface for an external amplifier for long range communication.

When transmitting the devices consume just 11.0mA. This decreases to 5.1mA when receiving and, in deep sleep mode, the current consumption is an extremely low 100nA. Both devices are housed in a 5- x 5-mm QFN40 package with a 0.4-mm pin pitch.
