Supply Voltage
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.
Speed/Power
There are four options of Speed/Power. These are Fast(F), Noise Reduced(N), Low Power(L) and Sleep mode(S).
Fast Mode(F) Is the fastest operating mode where the device operates with continuous sampling at the
fastest internal speed.
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.
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.
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.

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 on span, temperature effects on offset and second order temperature effects on 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 available
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).

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 measuring pressure
is called a Normal cycle. A cycle where either a temperature measurement or zeroing is being performed is called a Special
cycle.

Figure 1 - DLVR Essential Model
R
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 sensor also includes an internal temperature
reference and associated control logic to support the configured operating mode. The sensing element is powered down
while not being sampled to conserve power. Since there is a single ADC, there is also a multiplexer at the front end of the
ADC that selects the signal source for the ADC.

For either type of digital interface, the format of data returned from the sensor is the same. The first 16 bits consist of
the 2 Status bits followed by the 14-bit the pressure value. 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). Refer to Table 2 for the
overall data format of the sensor. Table 3 shows the Status Bit definition.

Digital Interface Data Format
all sensors
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.

All Sensors
DS-0300 Rev D

STOP condition (P): LOW to HIGH transition of the SDA line while clock (SCL) is HIGH indicates a STOP condition. STOP conditions are always generated by the master.
Signed Original O
DATA operation: The sensor starts to send 4 data bytes containing the current pressure and temperature values. The transmission may be halted by the host after any of the bytes by responding with a NACK.
www.allsensors.com
R
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.
f 408 225 2079
e www.allsensors.com
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 data request (READ).
p 408 225 4314
Signed Original On File
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.

Bus not Busy (I): During idle periods both data line (SDA) and clock line (SCL) remain HIGH.

Figure 3 illustrates the sequence of signals set by both the host and the sensor for each command. Note that for the DataRead command, the host has the option of responding to the second or third bytes of data with a NACK instead of ACK.
This terminates the data transmission after the pressure data, or after the pressure data and upper byte of temperature,
have been transmitted. See Figure 6 for the I2C timing details.

creates the same stall/deadlock. In the following data request, an additional Start condition must be sent for
correct communication.
3. A falling SDA edge is not allowed between the start condition and the first rising SCL edge. If using an I2C

applied. A second Start condition must be set, which clears the error and allows communication to proceed.

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 host 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 internal
temperature value and zero point data, in order to maintain accurate output values.
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).

Sleep Configuration

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 Sleep configuration, if the INT
pin is ignored, the host processor can repeat this command until the Status bits indicate an updated reading.

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.

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.

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.

DLVR sensors using the SPI interface option provide 3 signals for communication: SCLK, SS (Slave Select), and MISO.
This read-only signaling uses a hardware protocol to control the sensor, differing slightly with the speed/power option
selected as described below:
