The internal timer time-out triggers the next conversion cycle. The update rate is commensurately lower for this mode as a result. R R Noise Reduced(N): Also operates with continuous samples however the ADC is set for over sampling for noise reduction. The conversion times are resultantly longer than the Fast(F) mode however, there is approximately 1/2 bit reduction in noise. www.allsensors.com www.allsensors.com Fast Mode(F) Is the fastest operating mode where the device operates with continuous sampling at the fastest internal speed. Original In Red R There are four options of Speed/Power. These are Fast(F), Noise Reduced(N), Low Power(L) and Sleep mode(S). www.allsensors.com R R Devices are characterized at either 3.3V or 5.0V depending on the options selected. It is suggested to select the option that most closely matches the application supply voltage for best possible performance. Original In Red Interface www.allsensors.com The following is a list of factory programmable options. Consult the factory to learn more about the options. Speed/Power nsors.com R R w m In Red Device Options Over Sample Enable Control Logic I/O I2C/SPI all sensors Sample Temperature Wake The DSP receives the converted pressure and temperature information and applies a multi-order transfer function to compensate the pressure output. This transfer function includes compensation for span, offset, temperature effects of span, temperature effects of offset and second order temperautre effects of both span and offset. There is also linearity compensation for gage devices and front to back linearity compensation for differential devices. There are two effective operating modes of the sensor 1) Free Running and 2) Triggered. The control logic performs the synchronization of the internal functions according the factory programmed Power/Speed option (see Table 1). The Control Logic also determines the Delay between ADC samples, the regularity of the Special cycles and whether or not the ADC performs the Over Sampling. Refer to Figure 2 for the communication model associated with the operating modes listed below. R All Sensors Original In Red Triggered Mode: In the Triggered Mode, a conversion cycle is initiated by the user (or host uP). There are two availabe methods to wake the sensor from sleep mode. The first method (Wake All) is to wake the sensor and perform all three measurement cycles (Z, T and P). This provides completely fresh data from the sensor. The second method (Wake P) is to wake the sensor from sleep and only perform the pressure measurement (P).When using this second method, it is up to the user to interleave Wake All commands at regular intervals to ensure there is sufficiently up to date temperature information. Also, the Wake Pressure method is only available from the I2C interface (not available using a SPI interface). R Free Running Mode: In the free running mode, conversion cycles are initiated internally at regular intervals. There are three options available that operate in the Free Running mode (F, N and L). Two of these (F and N) run continuously while the third option (L) has an approximate 6 ms delay between conversion cycles. All three options have Special cycles inserted at regular intervals to accomplish the ADC zeroing and temperature measurements. Two of the options utilize oversampling. Refer to Table 1 for specific option controls. f 408 225 2079 The ADC performs conversions on the raw sensor signal (P), the temperature reference (T) and a zero reference (Z) during an ADC zero cycle. It also has an oversampling mode for a noise reduced output. A conversion cycle that is mesuring pressure is called a Normal cycle. A cycle where either a temperature measurement or zeroing is being performed is called a Special cycle. e www.allsensors.com Gnd p 408 225 4314 Original In Red P/T/Z Select D Pressure DSP www.allsensors.com Original In Red 0 Sensor rawP/ rawT A Original In Red DS-0300 Rev C Origi Page 5 www.allsen inal In Red 1 a 16035 Vineyard Blvd. Morgan Hill, CA 95037 Original In Red Original In Red www.allsensors.com R www.allsensors.com To R R 2 www.allsensors.com www.allsensors.com Zero R Vs Original In Red R Figure 1 - DLVR Essential Model www.allsensors.com www.allsensors.com The DLVR is a digital sensor with a signal path that includes a sensing element, a 14 bit analog to digital converter, a DSP and an IO block that supports either an I2C or SPI interface (see Figure 1 below).

The transmission may be halted by the host after any of the bytes by responding with a NACK. f 408 225 2079 e www.allsensors.com DATA valid (Dn): State of data line represents valid data when, after a START condition, data line is stable for duration of HIGH period of clock signal. Data on line must be changed during LOW period of clock signal. There is one clock pulse per data bit. Original In Red Acknowledge (A or N): Data is transferred in units of 8 bits (1 byte) at a time, MSB first. Each data-receiving device, whether master or slave, is required to pull the data line LOW to acknowledge receipt of the data. The Master must generate an extra clock pulse for this purpose. If the receiver does not pull the data line down, a NACK condition exists, and the slave transmitter becomes inactive. The master determines whether to send the last command again or to set the STOP condition, ending the transfer. a 16035 Vineyard Blvd. Morgan Hill, CA 95037 Original In Red Original In Red R www.allsensors.com R Slave address (An): The I²C-bus requires a unique address for each device. The DLVR sensor has a preconfigured slave address (0x28). After setting a START condition the master sends the address byte containing the 7 bit sensor address followed by a data direction bit (R/W). A "0" indicates a transmission from master to slave (WRITE), a "1" indicates a datarequest (READ). R START condition (ST): A HIGH to LOW transition of SDA line while the clock (SCL) is HIGH is interpreted as START condition. START conditions are always set by the master. Each initial request for a pressure value has to begin with a START condition. www.allsensors.com www.allsensors.com Bus not Busy (I): During idle periods both data line (SDA) and clock line (SCL) remain HIGH.

The third byte provides the 8 most significant bits of the measured temperature; the fourth byte provides the 3 least significant bits of temperature, followed by 5 bits of undefined filler data. With either interface, the host may terminate the transfer after receiving the first two bytes of data from the sensor, or following the third byte (if just the most-significant 8 bits of temperature are needed).

A falling SDA edge is not allowed between the start condition and the first rising SCL edge. If using an I2C address with the first bit 0, SDA must be held low from the start condition through the first bit. R 2. The Restart condition—a falling SDA edge during data transmission when the CLK clock line is still high— creates the same stall/deadlock. In the following data request, an additional Start condition must be sent for correct communication. a 16035 Vineyard Blvd. Morgan Hill, CA 95037 Original In Red Original In Red www.allsensors.com R www.allsensors.com R www.allsensors.com 1. Sending a Start condition, then a Stop condition, without any transitions on the CLK line, creates a communication error for the next communication, even if the next start condition is correct and the clock pulse is applied. A second Start condition must be set, which clears the error and allows communication to proceed. Original In Red I2C Exceptions www.allsensors.com Depending on the application, pressure measurements may be performed by sending the StartPressure command, which only measures the pressure value and uses previously measured temperature data in calculating the compensated output value. This presents the result faster (in about 1/3 the delay time) than the StartAll command. This can be a useful method to synchronize the sensor with the hose controller as well as attaining the fastest overall response time without Special cycles occuring at unwanted times. The system designer should determine the interval required for sending StartAll commands, necessary to refresh the temperature R The part enters Triggered mode (see table 1) after power-up, and waits for a command from the bus master. If the StartAll command is received, the temperature, ADC zero, and pressure readings are all measured, and correction calculations are performed. When valid data is written to the output registers, the INT pin is set high, and the processing core goes back to sleep. The host processor then sends the DataRead command to shift out the updated values. If the INT pin is not monitored, the host can poll the output registers by repeating the DataRead command until the Status bits indicate that the values have been updated (see Tables 2 and 3). The response time depends on configuration options (refer to Table 1 and Performance Characteristics). Original In Red Sleep Configuration www.allsensors.com R Fast, Noise Reduced or Low-power Configuration R Original In Red www.allsensors.com Depending on whether the Fast, Noise Reduced, Low-Power, or Sleep options have been selected, the command sequence differs slightly. See Figure 3 for details of the three I2C commands. The part enters Free Running mode (see table 1) after power-up: it performs an initial complete measurement, writes the calculated data to the output registers, sets the INT pin high, then goes to sleep. After a delay determined by the update rate option, the part will wake up, perform measurements, update the output registers, then go back to sleep. DataRead is the only command recognized; as with the Micropower configuration, if the INT pin is ignored, the host processor can repeat this command until the Status bits indicate an updated reading.

Refer to Figure 5 in the Interface Timing Diagram section for detailed timing data. As previously described, the incoming data may be terminated by raising SS after 2, 3, or 4 bytes have been received as illustrated below. www.allsensors.com nsors.com R Original In Red SPI Bit Pattern www.allsensors.com Sleep(S) Configuration: As with the I2C option, the part enters Triggered mode after power-up, and waits for a command from the bus master. To wake the part and start a measurement cycle, the SS pin must be driven low by the host for at least 8usec, then driven high. This can be done by shifting a dummy byte of 8 bits from the sensor. This bus activity can be considered the SPI StartAll command, where the rising edge of SS is the required input to start conversion. Updated conversion data is written to the output registers after a period dependent on configuration options ( see Performance Characteristics). After this update of the registers, the core goes to an inactive (sleep) state. The DataRead command simply consists of shifting out 2, 3, or 4 bytes of data from the sensor. The host can check the Status bits of the output to verify that new data has been provided. The part remains inactive following this read operation, and another StartAll operation is needed to wake the part when the next conversion is to be performed. R Fast(F), Noise Reduced(N) and Low-Power(L) Configurations: After power-up, the part enters Free Running mode and begins its periodic conversion cycle, at the interval determined by the programmed Power/Speed option. This is the simplest configuration. The only bus interaction with the host is the SPI DataRead operations. Polling the sensor at a rate slower than the internal update rate will minimize bus activity and ensure that new values are presented with each transfer. Note that the Status bits should still be checked to verify updated data and the absence of error conditions. Original In Red DLVR sensors using the SPI interface option provide 3 signals for communication: SCLK, SS (Slave Select), and MISO.
