EXTON

DO

External device enable. Asserted during wake up process and held active until device enters sleep mode. Can be used to control external DC-DC converters or other circuits that are not required when the device is in sleep mode so as to minimise power consumption.

9

WAKEUP

DI

When asserted into its active high state, the WAKEUP pin brings the DW3000 out of SLEEP or DEEPSLEEP states into operational mode.

This should be connected to ground if not used.

10

NRSTn

DIO

Reset pin. Active Low Output.

May be pulled low by external open drain driver to reset the DW3000.

Must not be pulled high by external source.

11

CLK

DI

SPI peripheral clock input.

12

MOSI

DI

SPI peripheral data input.

13

MISO

DO

SPI peripheral data output.

14

CSN

DI

SPI chip select. This is an active low enable input. The high-to-low transition on SPICSn signals the start of a new SPI transaction. SPICSn

can also act as a wake-up signal to bring DW3000 out of either SLEEP or DEEPSLEEP states.

15

IRQ

DI

Interrupt request output from the DW3000 to the host processor. By

default IRQ is an active-high output but may be configured to be active

low if required. For correct operation in SLEEP and DEEPSLEEP modes it should be configured for active high operation. This pin will float in SLEEP and DEEPSLEEP states and may cause spurious interrupts on the host unless pulled low externally (100kΩ recommended). When the IRQ functionality is not being used the pin may be reconfigured as a general purpose I/O line2 , GPIO8.
