INSCRIPTION MANUAL [DWM 1000]

The DWM 1000 module is based on Decawave’s DW 1000 Ultra Wideband (UWB) transceiver IC. It integrates

antenna, all RF circuitry, power management and clock circuitry in one module. It can be used in 2-way ranging

or TDOA location systems to locate assets to a precision of 10cm and supports data rates of up to 6.8 Mbps

Key Features

IEEE 802.15.4-2011 UWB compliant

Supports 4 RF bands from 3.5GHz to 6.5 GHz

Programmable transmitter output power

Fully coherent receiver for maximum range and accuracy

Designed to comply with FCC & ETSI UWB spectral masks

Supply voltage 2.8V to 3.6V

Low power consumption

Data rates of 110 kbps, 850 kbps, 6.8 Mbps

Maximum packet length of 1023 bytes for high data throughput applications

Integrated MAC support features

Supports 2-way ranging and TDOA

SPI interface to host processor

23mm x 13mm x 2.9 mm 24pin side castellation package

Key Benefits

Simplifies integration, no RF design required

Very precise location of tagged objects delivers enterprise efficiency gains and cost reductions

Extended communications range minimizes required infrastructure in RTLS

High multipath fading immunity

Supports very high tag densities in RTLS

Low cost allows cost-effective implementation of solutions

Low power consumption reduces the need to replace batteries and lowers system lifetime costs

Applications

Precision real time location systems (RTLS) using two-way ranging or TDOA schemes in a variety of markets.

Location aware wireless sensor networks (WSNs)

INSCRIPTION MANUAL Pin Map Information SIGNAL NAME PIN I/O (Default) DESCRIPTION SPICLK 20 DI SPI clock SPIMISO 19 DO (D-L) SPI data output. SPIMOSI 18 DI SPI data input. SPICSn 17 DI SPI chip select. This is an active low enable input. Digital Interface The high-to-low transition on SPICSn signals the start of a new SPI transaction. WAKEUP 2 DIO When asserted into its active high state the WAKEUP pin brings the DW1000 out of SLEEP or DEPPSLEEP states into operational mode.

INSCRIPTION MANUAL SIGNAL NAME PIN I/O (Default) DESCRIPTION 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. GPIO7 4 DIO (I) Defaults to operate as a SYNC input. THIS FUNCTIONALITY IS NOT APPLICABLE TO THE DWM1000. This pin may be reconfigured as a general purpose I/O pin, GPIO7 under software control. GPIO6/SPIPHA 9 DIO(I) General purpose I/O pin.
