DWM3000 IEEE 802.15.4-z UWB Transceiver Module

1 Overview

The DWM3000 module is an IEEE 802.15.4-2011 and IEEE 802.15.4z (BPRF mode) UWB implementation. RF components, Qorvo DW3110 UWB transceiver, and other components reside on-module. DWM3000 enables cost effective and reduced complexity integration of UWB communications and ranging features, greatly accelerating design implementation.

1.1 DWM3000 Functional Description

The DW3110 on-board the DWM3000 is a fully integrated low-power, single chip CMOS RF transceiver IC. The DWM3000 module requires no RF design as the antenna and associated analog and RF components are on the module.

The module contains an on-board 38.4 MHz reference crystal. The crystal has been trimmed in production to reduce the initial frequency error to approximately 2 ppm, using the DW3110 IC's internal on-chip crystal trimming circuit, see section 2.1.

Always-On (AON) memory can be used to retain DWM3000 configuration data during the lowest power operational states when the on-chip voltage regulators are disabled. This data is uploaded and downloaded automatically. Use of DWM3000 AON memory is configurable.

The on-chip voltage and temperature monitors allow the host to read the voltage on the VDD1 pin and the internal die temperature information from the DW3110.

See the DW3000 datasheet for more detailed information on device functionality, electrical specifications, and typical performance.

1.2 DWM3000 Power Up

DWM3000 is designed such that it can be powered in a number of different configurations depending on the application. These options are described below . Figure 1 shows the power up sequence when external power sources are applied. The power supply design should ensure that VDD2a/b and VDD3 are stable less than 10 ms after VDD1 (3.3 V) comes up, otherwise a device reset is required.

When the external power source is applied to the DWM3000 for the first time (cold power up), the internal Power On Reset (POR) circuit compares the externally applied supply voltage (VDD1) to an internal power-on threshold (approximately 1.5 V), and once this threshold is passed, the AON block is released from reset and the external device enable pin EXTON is asserted.

Then the VDD2a/b and VDD3 supplies are monitored and once they are above the required voltage as specified in the datasheet (2.2 V and 1.4 V respectively), the fast RC oscillator (FAST_RC) and crystal (XTAL Oscillator) will come on within 500 µs and 1 ms respectively.

The DWM3000 digital core will be held in reset until the crystal oscillator is stable. Once the digital reset is de-asserted the digital core wakes up and enters the INIT_RC state, (see Figure 1 an d Figure 2). Then once the configurations stored in AON and OTP have been restored (into the configuration registers) the device will enter IDLE_RC. Then the host can set the AINIT2IDLE configuration bit in SEQ_CTRL and the IC will enable the CLKPLL and wait for it to lock before entering the IDLE_PLL state.

1.3 SPI Host Interface

The host interface to DWM3000 is a 4-wire SPI-compatible slave. The assertion of SPICSn low by the SPI master indicates the beginning of a transaction.

The SPI interface is used to read and write registers in the DW3110 device. All data and address transfers on the SPI are most significant bit first. All address bytes are transmitted with MSB first, and all data is transmitted commencing with lowest addressed byte.

The SPIMISO I/O is required to go open-drain when SPICSn is de-asserted, to allow interoperation with other slaves on the SPI bus. SPI daisy chaining is not supported. This is the mode where the MISO, MOSI lines are passed through a device when it is not chip selected.

1.3.1 SPI Timing Parameters

The SPI slave complies with the Motorola SPI protocol within the constraints of the timing parameters listed in Table 1 and illustrated in Figure 3 and Figure 4.

1.3.2 SPI Operating Modes

Both clock polarities (SPIPOL=0/1) and phases (SPIPHA=0/1) are supported, as defined in the Motorola SPI protocol. The DW3110 transfer protocols for each SPIPOL and SPIPHA setting are given in Figure 5 and Figure 6.

1.3.3 SPI Transaction Formatting

The SPI command structure allows for 4 different types of SPI command:

Figure 7: SPI Command Formatting

DWM3000 IEEE 802.15.4-z UWB Transceiver Module

1.4 General Purpose Input Output (GPIO)

The DWM3000 provides 8 configurable pins.

On reset, all GPIO pins default to input. GPIO inputs, when appropriately configured, are capable of generating interrupts to the host processor via the IRQ signal.

See DW3000 datasheet and DW3000 user manual for full details of the configuration and use of the GPIO lines.

1.5 Always-On (AON) Memory

Configuration retention in lowest power states is enabled in DWM3000 by provision of an Always-On (AON) memory array with a separate power supply, VDD1. The DWM3000 may be configured to upload its configuration to AON before entering a low-power state and to download the configuration when waking up from the low–power state.

1.6 One-Time Programmable (OTP) Memory

The DWM3000 contains a 128x32-bit user programmable OTP memory that is used to store per chip calibration information.

1.7 Interrupts and Device Status

DWM3000 has a number of interrupt events that can be configured to drive the IRQ output pin. The default IRQ pin polarity is active high. A number of status registers are provided in the system to monitor and report data of interest. See DW3000 user manual for a full description of system interrupts and their configuration and of status registers.

1.8 MAC

A number of MAC features are implemented including CRC generation, CRC checking and receive frame filtering. See the DW3000 datasheet and DW3000 user manual for full details.

DWM3000 IEEE 802.15.4-z UWB Transceiver Module

2 DWM3000 Calibration

Depending on the end-use applications and the system design, DWM3000 settings may need to be tuned. To help with this tuning a number of built-in functions such as continuous wave TX and continuous frame transmission can be enabled. See the DW3000 user manual for further details.

The DWM3000 has crystal oscillator trimmed during module production but no transmit power or antenna delay calibration.

2.1 Crystal Oscillator Trim

DWM3000 modules are calibrated at production at room temperature to minimise initial frequency error to reduce carrier frequency offset between modules and thus improve receiver sensitivity. The calibration carried out at module production will trim the initial frequency offset to less than 2 ppm, typically.

2.2 Transmitter Calibration

In order to maximize range, DWM3000 transmit power spectral density (PSD) should be set to the maximum allowable for the geographic region in which it will be used. For most regions this is -41.3 dBm/ MHz.

As the module contains an integrated antenna, the transmit power can only be measured over the air. The Effective Isotropic Radiated Power (EIRP) must be measured, and the power level adjusted to ensure compliance with applicable regulations.

The DWM3000 provides the facility to adjust the transmit power in coarse and fine steps; 2 dB and 0.5 dB nominally. It also provides the ability to adjust the spectral bandwidth. These adjustments can be used to maximize transmit power whilst meeting regulatory spectral mask.

If required, transmit calibration should be carried out on a per DWM3000 module basis, see DW3000 user manual for full details.

2.3 Antenna Delay Calibration

In order to measure range accurately, precise calculation of timestamps is required. To do this the antenna delay must be known. The DWM3000 allows this delay to be calibrated and provides the facility to compensate for delays introduced by PCB, external components, antenna and internal DWM3000 delays.

To calibrate the antenna delay, range is measured at a known distance using two DWM3000 systems. Antenna delay is adjusted until the known distance and reported range agree. The antenna delay can be stored in OTP memory.

Antenna delay calibration must be carried out as a once-off measurement for each DWM3000 design implementation. If required, for greater accuracy, antenna delay calibration should be carried out on a per DWM3000 module basis, see DW3000 user manual for full details.

5 Antenna Performance

This section presents antenna radiation patterns for the DWM3000. As is illustrated in Figure 9, measured radiation patterns were made with the module mounted on a DWM3000EVB evaluation board.

Table 10 and Table 11 show antenna radiation patterns in channels 5 and 9, respectively. Three planes in spherical space about the centre of the board are measured, with theta and phi plots representing perpendicular polarisations.

The DWM3000 antenna is vertically polarised, meaning that the module is intended to be positioned vertically upright when used in an RTLS system. An omnidirectional radiation pattern is seen in the XZ plane when observed by another antenna which is also vertically polarised. This is shown in the XZ plane antenna patterns, where the vertically polarised plot, phi, has a circular, or omnidirectional shape.

If the antennas are oriented perpendicular relative to each other, then the polarisation changes. In this case, the horizontally polarised pattern, theta, applies and there are nulls at certain angles which can limit range and introduce location inaccuracy.

6 Application Information

6.1 Application Board Layout Guidelines

When designing the PCB onto which DWM3000 will be soldered, the proximity of the DWM3000 on-board ceramic monopole antenna to metal and other non-RF transparent materials needs to be considered carefully. Two suggested placement schemes are shown below.

For best RF performance, ground copper should be flooded in all areas of the application board, except in the areas marked "Keep-Out Area", where there should be no metal either side, above or below (e.g., do not place battery under antenna).

The placement schemes in Figure 10 show an application board with no non-RF transparent material in the keep-out area, or an application board with the antenna projecting off of the board so that the keep out area is in free-space. In this second scheme it is still important not to place metal components above or below the antenna in a system implementation. It is also important to note that the ground plane on the application board affects the DWM3000 antenna radiation pattern. In Figure 10 below, 'd' should ideally be 10 mm. This gives the most vertically polarized radiation pattern. As 'd' is increased from 10 mm the degree of vertical polarization reduces.

Figure 10: Application Board Keep-Out Areas

DWM3000 IEEE 802.15.4-z UWB Transceiver Module

6.2 Application Circuit Diagram

A simple application circuit integrating the DWM3000 module need only power the device and connect the device to a host controller, see Figure 11.

Figure 11: Example DWM3000 Application Circuit

6.3 GPIO and SPI I/O Internal Pull Up / Down

All of the GPIO pins have a software controllable internal pull up/down resistor to ensure safe operation when input pins are not driven. This defaults to enabled and pull-down except for the SPICSn pin which defaults to pull-up. The value of the pull-up / down will vary with the VDD1 supply voltage over a range from 10 kΩ to 30 kΩ.
