Note 1 There are two types of pads, namely Type A and Type B. Type A is a normal IO pad with a Schmitt trigger on input while Type B has an extra RC Filter with a cutoff frequency of 100 kHz.

Note 2 This pin is also used for communication to the internal SPI Flash.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, so functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specification are not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

There are some special considerations for the use of the DA14531 TINY TM module, namely:

• The RST signal is shared with the MOSI input of the NOR flash. For this reason, RST must not be driven to GND. When the internal Flash is in use, the reset functionality is not available.
• The SPI Bus of DA14531 is used for the communication of the SoC with the NOR Flash at boot time. Three of the four signals are not driven to external module pins. For this reason, a sensor that utilizes the SPI bus must be assigned (by software) to the module pins to communicate with after the boot is completed and when NOR Flash is no longer in use. An example is given in Figure 8.
