An IEEE802.15.4UWB o plia t i eless t a s ei e odule ased o De aWa e’s DW IC. Fully coherent receiver for maximum range and accuracy. Designed to comply with FCC & ETSI UWB spectral masks Supply voltage 2.8V to 3.6V SPI Interface to host processor Key Benefits High immunity to multipath fading – allows reliable communications in high fading environments Low power consumption allows operation from batteries for long periods* Small physical size allows the implementation of cost-effective solutions in RTLS and WSN Integrated antenna allows simple product implementation – no RF design required Integration of DW1000 IC, antenna, power management and clock control simplifies design integration Very precise location of tagged objects delivers enterprise efficiency gains and cost reductions Long LOS and NLOS range reduces amount of infrastructure required to deploy systems Low power consumption reduces the need to replace batteries and lowers system lifetime costs Standards based solution (IEEE802.15.4-2011), eases proliferation Low cost allows cost-effective implementation of solutions The ED0991 module interfaces to an application microcontroller via SPI bus. Physical and MAC layer functionality are accessed via the SPI bus, through addressable registers as well as execution commands. Data received or to be transmitted are also accessed through the SPI bus and are implemented as a FIFO register (64 bytes each for TX and RX). To transmit, a frame of data is placed in the FIFO, this may include a destination address. A transmit command is given, which will transmit the data according to the initial setup of the registers. To receive data a receive command is given, which will listen for a transmission and when one occurs put the received frame in the FIFO. When neither transmit nor receive is required the device can enter either an Idle mode, from which it can quickly re-enter receive or transmit mode or it can enter a low power sleep mode, from which a crystal startup is also required prior to transmit or receive operation. A block diagram is given for the ED0991 module in Figure 1. Antenna The antenna couples energy between the air and the module. The ED0991 module has an integrated antenna that is near omni-directional. Note that the end radiation pattern depend not only on the antenna, but also the ground plane, enclosure and installation environment. Matching The matching provides the correct loading of the transmit amplifier to achieve the highest output power as well as the correct loading for the receive LNA to achieve the best sensitivity. Physical The physical layer provides conversions between data, symbol and RF signal. MAC The MAC layer is part of the Logical Link Layer and provides frame handling, addressing and medium access services. Microcontroller Interface The microcontroller interface exposes registers and commands for the physical and MAC layers to a microcontroller. Power Management Power management ensures a stable supply for the internal functions as well as providing means for a low power sleep mode, in which most of the transceiver is power off. Figure 1 Typical Flow After initial setup of registers for desired behavior, the normal operation flow diagram is shown in. In applications of infrequent data transmissions the transceiver would be in SLEEP mode to save power (<100nA). From there it would be woken up and enter WAKEUP mode. As part of the wake up process the crystal oscillator is started (~4ms) and the digital microcontroller interface is powered up. Before transmit or receive the frequency synthesizer needs to be started RSTn and having been powered off (or idle for a while) the control loop of the VCO/PLL needs to be calibrated INIT. A data frame is loaded into the transmit FIFO and the TX mode is entered. In the TX state the DW1000 actively transmits a frame containing the contents of the transmit buffer on the configured RF channel with the configured transmit parameters (PRF, data rate, preamble code etc.) Once the frame transmission is complete the DW1000 may enter one of three modes depending on the programmed configuration. After the frame transmission is complete the DW1000 will return to the IDLE state unless the ATXSLP bit is set (in Sub-Register 0x36:04 – PMSC_CTRL1) in which case the DW1000 will enter the SLEEP or DEEPSLEEP state automatically, (as long as no host interrupts are pending). When transmit is complete RX mode is entered to either hunting for preamble or (once it has detected preamble) actively receiving preamble searching for SFD, and subsequently receiving the PHR, decoding it and receiving the data part of the frame. In the RX state, the RF synthesizer and all RX blocks are active. After an event that ends the reception, (either a good frame RX, or some error or timeout event that aborts reception) the DW1000 will return to the IDLE state unless the ARXSLP bit is set (in Sub-Register 0x36:04 – PMSC_CTRL1) in which case the DW1000 will enter the SLEEP or DEEPSLEEP state automatically (as long as no host interrupts are pending).

Overview The ED0991 module is an IEEE 802.15.4-2011 UWB implementation. RF components, Decawave DW1000 UWB transceiver, and other components reside on-module. ED0991 enables cost effective and reduced complexity integration of UWB communications and ranging features, greatly accelerating design implementation. 1.1. ED0991 Functional Description The ED0991 on board the ED0991 is a fully integrated low-power, single chip CMOS RF transceiver IC compliant with the IEEE 802.15.4-2011 [1] UWB standard. The module contains an on-board 38.4 MHz reference crystal. The crystal has been trimmed in production to redu e the i itial f e ue e o to app o i atel pp , usi g the DW IC’s i te al o -chip crystal trimming circuit, see section 2.1.1. Always-On (AON) memory can be used to retain ED0991 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 ED0991 AON memory is configurable. The on-chip voltage and temperature monitors allow the host to read the voltage on the VDDAON pin and the internal die temperature information from the DW1000. See the DW1000 Datasheet [2] for more detailed information on device functionality, electrical specifications and typical performance. 1.2. ED0991 Power Up Figure 2:ED0991 Power up sequence When power is applied to the ED0991, RSTn is driven low by internal circuitry as part of its power up sequence. See Figure 2 above. RSTn remains low until the on-module crystal oscillator has powered up and its output is suitable for use by the rest of the device, at which time RSTn is deasserted high. Table 1: ED0991 Power up Timing Parameter VON TEXT_ON TDIG_ON Description Voltage threshold to enable power up Time at which EXTON goes high before RSTn is released RSTn held low by internal reset circuit / driven low by external reset circuit Nominal Value 2.0 Units msec msec RSTn may be used as an output to reset external circuitry as part of system bring-up as power is applied. An external circuit can reset the ED0991 by asserting RSTn for a minimum of 10 ns. RSTn is an asynchronous input. ED0991 initialization will proceed when the pin is released to high impedance. RSTn should never be driven high by an external source. Please see DW1000 Datasheet [2] for more details of DW1000 power up. 1.3. SPI Host Interface The DW1000 host communications interface is a slave-only SPI. Both clock polarities (SPIPOL=0/1) and phases (SPIPHA=0/1) are supported. The data transfer protocol supports single and multiple byte read/writes accesses. All bytes are transferred MSB first and LSB last. A transfer is initiated by asserting SPICSn low and terminated when SPICSn is deasserted high. See the DW1000 Datasheet [2] for full details of the SPI interface operation and mode configuration for clock phase and polarity. Figure 3 ED0991 SPIPHA=0 TRANSFER PROTOCOL 1.3.1.

GPIO The ED0991 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. GPIO0, 1, 2, & 3, as one of their optional functions, can drive LEDs to indicate the status of various chip operations. Any GPIO line being used to drive an LED in this way should be connected as shown. GPIO5 & 6 are used to configure the operating mode of the SPI as described in the DW1000 Datasheet [2]. See DW1000 Datasheet [2] and DW1000 User Manual [3] provide full details of the configuration and use of the GPIO lines. 1.5. Always-On Memory (AON) Configuration retention in lowest power states is enabled in ED0991 by provision of an Always-On (AON) memory array with a separate power supply, VDDAON. The ED0991 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 Memory The ED0991 contains a 56x32 -bit user programmable OTP memory on the DW1000 device that is used to store per chip calibration information. 1.7. Interrupts and Device Status ED0991 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 DW1000 User Manual [3] 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 DW1000 Datasheet [2] and DW1000 User Manual [3] for full details 1.9. External Synchronization The DW1000 provides a SYNC input. This allows: - • Synchronization of multiple DW1000 timestamps • Transmission synchronous to an external reference • Receive time stamping synchronous to an external counter See the DW1000 Datasheet [2] and DW1000 User Manual [3] for full details. 2.
