The acquisition system includes anti-alias filters, data acquisition, 50/60Hz notch filter, sensor compensation, bandwidth limiting and I/O functions. Refer to the figure below for the ND Series block diagram. Block Diagram User Control Registers Pressure Sensor Anti-Alias Filter Mode Control Δ-Sigma Modulator 1b Va Anti-Alias Filter 3b BW Control HW Interface Rate Controller Δ-Sigma Modulator Decimation To Enable Rate Control 4 50/60Hz Notch (Sinc1) 4 Compensation FPU with Linearization 4 BW Limit IIR (2nd Order) SPI/I2C Interface DAV nRST MISO/SDA MOSI/SCL SCK nSS SAR ADC 26 Term Compensation Coefficients SAR ADC FIG-0125A Vs MCU There are also two user controlled registers that tune the sensor to the specific user requirements. The first register is the Mode Control register that determines the output pressure range, the corner frequency of the bandwidth limiting filter and enables or disables the 50/60Hz notch filter. www.SuperiorSensors.com Rate Control Register Reload Value Internal Update (fUPDATE) Down Counter Zero Data Read 7 S R Q DAV FIG-0012B The second register is the Rate Control register which controls the rate at which the Data Available (DAV) pin is asserted. The internal sensor data update rate of 444 Hz is often much faster than industrial requirements so the Rate Control register can throttle down the rate at which the Data Available pin (DAV) is asserted. The DAV is reset upon each read of the pressure sensor. An internal model of the Rate Controller is illustrated in the figure to the right. ND Series Industrial Absolute Middle Pressure Sensors 10 Interface 10.1 Reset Reset timing is shown in the diagram below. The communications method (SPI or I2C) is established during the time just after reset. During this time (tIOD), no communications should take place. Also, the internal filters are settling during the time tFRD and data acquired during this time may not be fully settled. Reset Timing Diagram VPORR VDD VPORF Internal Reset tRSTL _RST tIOD Communications Available tIOD tFRD tFRD FIG-0021A Filters Settled 10.2 Communication Interface Selection The communications interface is selected by interrogating the nSS pin after the internal power on reset delay. If nSS is high, the SPI interface will be selected otherwise (if low) the I2C interface will be selected. Grounding the nSS pin is an acceptable method for selecting the I2C interface. NOTE: The I2C interface supports 10 interface addresses. Refer to section 10.4.1 for the details on I2C address selection. 10.3 SPI Interface The SPI interface uses a 16 bit transfer for all communications. Data is MSB first for both MOSI and MISO data transfers. Refer to the figure below for specific timing requirements. SPI Timing Diagram ts c tcc tbc tcn tcs SCK MOSI Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 MISO Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 FIG-0013A nSS The data communication has been reduced to a simple 16 bit transfer model for reading the pressure output. Each communication cycle consists of master sending the Mode and Rate data to be placed into the sensor Mode Register and Rate Registers respectively. Simultaneously, the sensor sends the pressure data for the master to receive. Refer to the figure below for the data communication model of the ND Series sensor. www.SuperiorSensors.com 8 ND Series Industrial Absolute Middle Pressure Sensors The requirement to send the Mode and Rate bytes on each data read cycle is intentional. The purpose is to force the master to send specific data for each communication and prevent inadvertent data from being sent to the sensor. Since a SPI interface will generally re-circulate data through its shift register, the intention is to prevent the pressure output from the sensor from being re-circulated back to the sensor and potentially causing unintended corruption of the intended mode register. SPI Data Diagram SCK MOSI User Mode Byte User Rate Byte MISO Pressure Output High Byte Pressure Output Low Byte FIG-0014A nSS 10.4 I2C Interface The ND Series is compatible with the I2C protocol. For detailed information regarding the I2C protocol, please refer to the Philips I2C Bus Specification, Version 2. 10.4.1 I2C Address I2C Address Selection Table Address Address (decimal) (hex) 5.6 49 0x31 12 48 0x30 27 47 0x2F 51 46 0x2E 100 45 0x2D 100 44 0x2C 100 43 0x2B 100 42 0x2A 100 41 0x29 NoPop 40 0x28 R1 (kΩ) R2 (kΩ) 120 120 120 120 120 56 30 15 5.6 0 The I2C address is set to 0x28 by grounding the SCK line. Other I2C addresses can be established by applying a voltage to the SCK line by use of a resistor divider across the sensor supply voltage. The suggested resistor values and the respective I2C address are shown in the table to the left. Note: R1 is the lower resister of the divider where R2 is the upper resistor of the divider. 10.4.2 I2C Communications Model The sensor is configured as a slave device and as such, the communicating host must be configured as a master. There are two types of possible data transfers, data transfers from the master transmitter to an addressed sensor (WRITE), and data transfers from an addressed sensor to a master receiver (READ). The master device initiates both types of data transfers and provides the serial clock pulses on SCL. The communications model for I2C is similar to that of SPI however, since I2C is a half-duplex protocol, the transfer of information to and from the sensor is separated into two separate communications. This is in contrast to the SPI interface where the transmitted and received data occurs simultaneously to and from the host. Refer to the figure to the right for the data communication model for the ND Series sensors. www.SuperiorSensors.com 9 ND Series Industrial Absolute Middle Pressure Sensors 10.4.3 I2C Clock Stretching The figure to the right illustrates the I2C clock stretching by the sensor. At times, the sensor requires additional time to respond to the host and utilizes the clock stretching feature of the I2C protocol. This is accomplished by holding the SCL low after the ACK cycle of a data transfer. Refer to Section 7.4 for the clock stretching timing. Note, the maximum clock stretch time will generally only occur once during the three ACK cycles of a two byte transfer. That is, the balance of ACK's during a multi-byte transfer will generally include the typical clock stretching time. 10.4.4 I2C Bus Compatibility The I2C specification allows any recessive voltage between 3.0 and 5.0 V. Different devices on the bus may operate at different voltage levels. However, the maximum voltage on any port pin must conform to the electrical characteristics specifications (See section 1). The bi-directional SCL (serial clock) and SDA (serial data) lines must be connected to a positive power supply voltage through a pull-up resistor or similar circuit. Every device connected to the bus must have an open-drain or open-collector output for both the SCL and SDA lines, so that both are pulled high (recessive state) when the bus is free. 10.5 Extended Data Acquisition 10.5.1 Available Extended Data For either the SPI or I2C interface, additional data is available beyond the pressure. The means to access this extended data is to continue reading data (either SPI or I2C) beyond the first 16 bits of pressure information. The following table defines the order of the available data and respective format. Data Bytes Format Interpretation Example Pressure 1-2 2 byte, Unsigned Int See Section 10.7 See Section 10.7 Temperature 3-4 2 byte, Signed Int Fixed Decimal [8.8 bits], Upper 8 bits integer, lower 8 bits fractional. Temperature in °C 1880H (18.80H) = 24.5°C Model 5-12 8 byte, ASCII, null terminated Right reading ASCII with null termination 4EH,44H,30H,31H,35H,41H,00H,xxH = ND015A Serial Number 13-16 4 byte, Hex Unique 4 byte serial for each part 2FD627A4H Build Number 17-22 6 byte, ASCII, null terminated Right reading ASCII with null termination 30H,31H,34H,37H,41H,00H = 0147A 10.5.2 SPI Extended Data Read Reading the extended data while using the SPI interface is the same as shown in Section 10.3 with the exception that the master continues to read during the same nSS sequence to read all 22 bytes of the extended data. Any portion of the 22 bytes can be read during the transfer. That is, for example, 4 bytes could be read to acquire only the pressure and temperature information. When reading the extended data, only the first two bytes sent to the sensor (User Mode and User Rate) are used to set the internal registers. The subsequent bytes (bytes 5 through 22) are ignored. Data read following the first 22 bytes is undefined. www.SuperiorSensors.com 10 ND Series Industrial Absolute Middle Pressure Sensors 10.5.3 I2C Extended Data Read Reading the extended data via the I2C interface is similar to using the SPI interface where the master can simply continue to reading the sensor during the pressure reading transfer. The master continues Ack'ing until the number of desired bytes are read. 10.6 Control Registers 10.6.1 Mode Control Register Mode Control Register Detail Default Value: 0xF7 Mode Register (General) Details of the Mode Control register are illustrated in the figure to the right. b7 b6 b5 b4 b3 b2 b1 b0 Pressure Range Select Bits 0-2 control the output pressure range. I/O Watchdog Enable BW Limit Select Bit 3 is the I/O Watchdog Enable bit. When set, the I/O watchdog is enabled. When enabled, the I/O watchdog will monitor the I/O activity. If I/O activity is not detected for the I/O Watchdog timeout time, the pressure sensor will reset itself. The I/O watchdog timeout time is determined by the currently active bandwidth setting. Notch Enable Mode Register (Detail) b7 b6 b5 b4 b3 b2 b1 b0 Bits 4-6 control the BW Limit Filter. ND015A Bit 7 is the Notch Filter Enable bit. When enabled, the 50/60Hz notch filter is active. It should be noted that upon changing the Mode Control value, there is a one cycle latency before the new Mode Control value becomes valid. That is, the data of the communication cycle following a change to the Mode Control register will not reflect the change. It is not until the second communication cycle that the change in the Mode Control register will be reflected in the output data. 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 Pressure Range Select (by Model) ND030A ND060A ND100A ND150A Reserved Do NOT Use 15.0 psi 30.0 psi 60.0 psi 100 psi 150 psi I/O Watchdog Enable 0 Disabled 1 Enabled BW Limit Select I/O Watchdog Timeout 0 0 0 1.0 Hz 1 sec 0 0 1 2.0 Hz 500 ms 0 1 0 5.0 Hz 200 ms 0 1 1 10 Hz 200 ms 1 0 0 20 Hz 200 ms 1 0 1 50 Hz 200 ms 1 1 0 100 Hz 200 ms 1 1 1 200 Hz 200 ms www.SuperiorSensors.com 11 Notch Filter Disabled 1 Notch Filter Enabled FIG-0126A Notch Enable 0 ND Series Industrial Absolute Middle Pressure Sensors 10.6.2 Rate Control Register Default Value: 0x1C Rate Control Register Detail The Rate Control Register controls the rate at which the DAV pin is asserted indicating new data is available. This register is primarily used to throttle down the actual data transfer rate (when using the DAV as the trigger to sample) since the general industrial requirement is less than the internal 444 Hz update rate. This register functions as the reload value of a data rate counter. The value of the Rate Control Register is the divisor of the 444 Hz internal data rate. Since a divisor of zero is not possible, a zero value will select the auto-select rate mode. In this mode, the rate is selected based on the selected bandwidth limit. The auto rate value is roughly 3x the corner frequency of the selected bandwidth limit in all auto selected rates (where possible). b6 b5 b4 b3 b2 b1 b0 0 0 0 0 0 0 0 0 Auto Select 0 0 0 0 0 0 0 1 444 Hz 0 0 0 0 0 0 1 0 222 Hz 0 0 0 0 0 0 1 1 148 Hz 1 1 1 1 1 1 1 0 1.75 Hz 1 1 1 1 1 1 1 1 1.74 Hz Selected BW Limit Auto Select Rate 1.0 Hz 3.0 Hz 2.0 Hz 6.0 Hz 5.0 Hz 15.3 Hz 10 Hz 31.7 Hz 20 Hz 63.4 Hz 50 Hz 148 Hz 100 Hz 444 Hz 200 Hz 444 Hz Note: Start-up time for the sensor is approximately 80ms for the first sample to be settled. Requesting data during this time will result in invalid information. However, this start-up time can be used for configuring the Mode and Rate registers by performing a transfer with the desired Mode and Rate register values and discarding the received pressure data. After waiting the required start-up time, the sensor will respond with desired data since the Mode and Rate registers have been pre-established. FIG-0084A Rate Control Register b7 10.7 Computing Pressure The pressure data is in the form of 16 bit unsigned integer sent in high byte then low byte order. This is a single ended output by definition and the data range is 0 to 216. There is a 10% margin (5% either end) in the output scaling and the selected full scale will reside in the 5% to 95% of the total available output data range. Refer to Equation 1 (below) for the general model for computing the output pressure. As an example, if the sensor output is 37,646 counts using an ND015A (15 psia) device, then the output pressure is 8.74 psia.
