Function Outlines and Features

1.1. Function Outlines

TC35680FSG/TC35681FSG series (hereafter, TC35680/TC35681 series) are compliant with 2.4 GHz wireless communication

Bluetooth® Low Energy Ver.5.0 specification. Each device has an MCU based on Arm® Cortex-M0® processor and integrates RF

analog circuit and baseband digital circuits. The following functions in the Bluetooth® core specifications are supported; the LE Long

Range feature, LE 2-Mbps feature, HCI (Host Control Interface) feature, Low Energy GATT Profile feature, and others.

The TC35680/TC35681 series line-up is as follows:



TC35680FSG (hereafter, TC35680): Flash memory is included to store user application program.



TC35681FSG (hereafter, TC35681): Flash memory is not included.

TC35680/TC35681 series support both controlled by an external CPU and standalone operation.

Table 1-1 shows the main application and features of each device.
