DA14531MOD-00F01002 Pinout

Package: LCC-16 (14.5×12.5 mm)

Notes

• J1: No internal connection; must be connected to ground externally per datasheet note.
• Power pins: VBAT (J7) and multiple GND pins (J2, J3, J4, J6, J11) provide power distribution.
• Debug pins: P0_10/SWDIO (J9) and P0_2/SWCLK (J10) support Serial Wire Debug interface.
• Reset pin: P0_0/RST (J12) serves as the device reset input.
• UART pin: P0_5/RxTx (J14) supports UART communication.
• All GPIO pins are on Port 0 (P0_x).

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.

Table 3: Recommended operating conditions

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.
