General Description

The DLVR Series Mini Digital Output Sensor is based on All Sensors’CoBeam^{2 TM}Technology. This reduces package stress

susceptibility, resulting in improved overall long term stability. The technology also vastly improves position sensitivity

compared to single die devices.

The supply voltage options ease integration of the sensors into a wide range of process control and measurement sys-

tems, allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter

very low-power modes between readings to minimize load on the power supply.

These calibrated and compensated sensors provide accurate, stable output over a wide temperature range. This series

is intended for use with non-corrosive, non-ionic working ﬂuids such as air, dry gases and the like. A protective parylene

coating is optionally available for moisture/harsh media protection.

Device Options

The following is a list of factory programmable options. Consult the factory to learn more about the options.

Interface

I2C and SPI interfaces are available. NOTE: SPI interface is only available with eight (8) lead packages.

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.

Coating

Parylene Coating: Parylene coating provides a moisture barrier and protection form some harsh media. Con-

sult factory for applicability of Parylene for the target application and sensor type.

Operation Overview

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.

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 compensa-

tion 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 per-

forms 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).

Digital Interface Data Format

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 mea-

sured 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.

Status (S): Normal/command / busy / diagnostic

Table 3- Status Bit Deﬁnitions

I2C Interface

I2C Communications Overview

The I2C interface uses a set of signal sequences for communication. The following is a description of the supported

sequences and their associated pneumonic. Refer to Figure 3 for the associated usage of the following signal sequences.

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

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.

Slave address (An): The I²C-bus requires a unique address for each device. The DLVR sensor has a preconﬁg-

ured 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).

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.

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.

DATA operation: The sensor starts to send 4 data bytes containing the current pressure and temperature val-

ues. The transmission may be halted by the host after any of the bytes by responding with a NACK.

STOP condition (P): LOW to HIGH transition of the SDA line while clock (SCL) is HIGH indicates a STOP condi-

tion. STOP conditions are always generated by the master.

Figure 3 illustrates the sequence of signals set by both the host and the sensor for each command. Note that for the Da-

taRead 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.

Page 8

I2C Command Sequence

Depending on whether the Fast, Noise Reduced, Low-Power, or Sleep options have been selected, the command se-

quence diﬀers slightly. See Figure 3 for details of the three I2C commands.

Fast, Noise Reduced or Low-power Conﬁguration

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 deter-

mined 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.

Sleep Conﬁguration

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 cor-

rection 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).

Depending on the application, pressure measurements may be performed by sending the StartPressure com-

mand, 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 attain-

ing 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

I2C Exceptions

1. Sending a Start condition, then a Stop condition, without any transitions on the CLK line, creates a com-

munication 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.

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.

3. 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.

SPI Interface

SPI Command Sequence

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:

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 opera-

tions. 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.

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 rais-

ing SS after 2, 3, or 4 bytes have been received as illustrated below.
