Con- Signed Original O R Coating R Sleep(S): Is similar to the Low Power(L) mode however the trigger to initiate a sample comes from the user instead of an internal timer. This is ideal for very low update rate applications that requirelow power usage. It is also ideal for synchronizing the data conversions with the host microprocessor. www.allsensors.com ors.com Low Power(L): Is similar to the Fast(F) mode with exception that the device uses an internal timer to delay between pressure conversions. The internal timer time-out triggers the next conversion cycle. The update rate is commensurately lower for this mode as a result. Signed Original On File 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 R Fast Mode(F) Is the fastest operating mode where the device operates with continuous sampling at the fastest internal speed. Figure 1 - DLVR Essential Model all sensors Control Logic Wake Gnd 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. 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. 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. 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).

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.

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). Signed Original On File R Sleep Configuration www.allsensors.com www.allsensors.com 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. Signed Original On File R Fast, Noise Reduced or Low-power Configuration R 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. www.allsensors.com ors.com w.allsensors.com Signed Original On File I2C Command Sequence Signed Original On F R 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. SPI Bit Pattern The sequence of bits and bus signals are shown in the following illustration (Figure 4). 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.

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.
