Most of the available signals are utilized or extracted on the breakout connectors. Table 1 shows the pin assignment on the development kit peripheral function and the related pin name on the FCGQFN24 package of the DA14535. Table 1. DA14535 USB development kit pin assignment UART XTAL Single... -
Page 11: Default Configuration
DA14535 USB Development Kit Hardware Default Configuration Because GPIOs P0_0 to P0_6 support multiple functions, the default system is limited to a subset of the possible options. Figure 6 shows the default DIP switch configuration. Figure 6. Default DIP switch configuration This allows the system to boot from external flash or 1-wire UART and communicate through JTAG for debugging. -
Page 12: 1-Wire Bootable Uart
Since most UART communication is typically half-duplex, it is possible to use a single pin for both the Rx and the Tx channel. DA14535 has dedicated hardware that supports this function and two related boot steps predefined. An analog multiplexer shown in... -

Page 16: Spi Data Flash Memory (U2)
The selected flash for the DA14535 USB development kit is a 2-Mbit Renesas Semiconductor AT25DF021A- MAHN-T. The DA14535 USB development kit can also support other types of external SPI flash in USON-8 2 mm × 3 mm, SOIC-8 150 mil, and SOIC-8 208 mil packages (Figure 11). -
Page 17: Reset Circuit
DA14535 USB Development Kit Hardware 5.10 Reset Circuit The DA14535 can allocate the power-on-reset input to any GPIO using high or low polarity. This configuration is done by the application software after the boot sequence has finished. However, the only option for a hardware reset before the boot sequence has started is fixed to P0_0 with a high polarity. -
