## 6 Module Information and Mechanical Drawing
DW1000-V2:
Pad Number| Name|Pin Type|Description
---|---|---|---|---
1 | EXTON| Digital output |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 minimize power consumption.
2 | WAKEUP | Digital input| When asserted into its active high state, the WAKEUP pin brings the DW1000 out of SLEEP or DEEPSLEEP states into operational mode. When this pin is not being used as WAKEUP it should be tied to VSSIO.
3| RSTn|Digital input/output |Reset pin. Active Low Output. May be pulled low by external open drain driver to reset the DW1000.Must not be pulled high by external.
4| SYNC|Digital input/output |The SYNC input pin is used for external synchronization. When the SYNC input functionality is not being used this pin may be reconfigured as a general purpose I/O pin, GPIO7.
5| VDDAON| Power| External supply for the Always-On (AON) portion of the chip.
6| VDD3v3_1 | Power|
7| VDD3v3_0 | Power|
8| VSS0| Ground| Negative I/O ring supply. Must be connected to ground.
9| GPIO6| Digital input/output| General purpose I/O pin.
10| GPIO5| Digital input/output| General purpose I/O pin.
11| GPIO4| Digital input/output| General purpose I/O pin.
12| GPIO3| Digital input/output| General purpose I/O pin.
13| GPIO2| Digital input/output| General purpose I/O pin.
14| GPIO1| Digital input/output| General purpose I/O pin.
15| GPIO0| Digital input/output| General purpose I/O pin.
16| VSS1| Digital input/output| Negative I/O ring supply. Must be connected to ground.
17|SPI_CSn| Digital input| 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 DW1000 out of either SLEEP or DEEPSLEEP states.
18| SPI_MOSI| Digital output| SPI data input.
19| SPI_MISO| Digital input| SPI data output.
20| SPI_CLK |Digital input |SPI clock.
21| VSS2| Ground| Negative I/O ring supply. Must be connected to ground.
22| IRQ |Digital input/output| interrupt Request output from the DW1000 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 unless pulled low. When the IRQ functionality is not being used the pin may be reconfigured as a general purpose I/O line, GPIO8. This pin has an internal pulldown to VSSIO and can be left unconnected if not being used.
23| VSS3|Ground|Negative I/O ring supply. Must be connected to ground.
24|VSS4|Ground |Negative I/O ring supply. Must be connected to ground.
