The digital interface eases integration of the sensors into a
wide range of process control and measurement systems,
allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter very
low-power mode 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.

Operation Overview
The DLHR is a digital sensor with a signal path that includes a sensing element, a variable- 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.
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.
After completion of the measurement, the result may then be read using the Data Read command. The ADC and DSP
remain in Idle state, and the I/O block returns the 7 bytes of status and measurement data. See Figure 2, following. At
any time, the host may request current device status with the Status Read command. (See Table 1 for a summary of all
commands.)
For optimum sensor performance, All Sensors recommends that Measurement commands be issued at a fixed interval
by the host system. Irregular request intervals may increase overall noise on the output.
Furthermore, if reading intervals are much slower than the Device Update Time, using the Averaging commands is
suggested to reduce offset shift. This shift is constant with respect to time interval, and may be removed by the application. For longer fixed reading intervals, this shift may be removed by the factory on special request.
I/O Interface Configuration: The sensor automatically selects SPI or I2C serial interface, based on the following protocol: If the /SS input is set low by the host (as occurs during a SPI command transaction), the I/O interface will remain
configured for SPI communications until power is removed. Otherwise, once a valid device address and command
have been received over the I2C interface, the I/O interface will remain configured for I2C until power is removed.
NOTE: The four-pin (SIP) packages only support the I2C interface.

DS-0350 Rev C
Page 6 of 18
f 408 225 2079
Sensor Commands: Five Measurement commands are supported, returning values of either a single pressure / temperature reading or an average of 2, 4, 8, or 16 readings. Each of these commands wakes the sensor from Idle state into
Active state, and starts a measurement cycle. For the Start-Average commands, this cycle is repeated the appropriate
numper of times, while the Start-Single command performs a single iteration. When the DSP has completed calculations and the new values have been made available to the I/O block, the sensor returns to Idle state. The sensor
remains in this low-power state until another Measurement command is received.
p 408 225 4314
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.
a 16035 Vineyard Blvd. Morgan Hill, CA 95037
The ADC performs conversions on the raw sensor signal (P), the temperature reference (T) and a zero reference (Z)
during the ADC measurement cycle.

When requesting the start of a measurement, the command length for I2C is 1 byte, for SPI it is 3 bytes.
When requesting sensor status over I2C, the host simply performs a 1-byte read transfer.
When requesting sensor status over SPI, the host must send the Status Read command byte while reading 1 byte.
When reading sensor data over I2C, the host simply performs a 7-byte read transfer.
When reading sensor data over SPI, the host must send the 7-byte Data Read command while reading the data.

Digital Interface Data Format
For either type of digital interface, the format of data returned from the sensor is the same. The first byte consists of
the Status Byte followed by a 24-bit unsigned pressure value and a 24-bit unsigned temperature value. Unused bits
beyond the calibrated bit width are undefined, and may have any value. See the Pressure Output Transfer Function
and Temperature Output Transfer Function definitions on page 3 for converting to pressure and temperature.
Refer to Table 2 for the overall data format of the sensor. Table 3 shows the Status Byte definition.

I2C Interface
I2C Command Sequence
The part enters Idle state after power-up, and waits for a command from the bus master. Any of the five Measurement
commands may be sent, as shown in Table 1. Following receipt of one of these command bytes, the EOC pin is set
to Low level, and the sensor Busy bit is set in the Status Byte. After completion of measurement and calculation in the
Active state, compensated data is written to the output registers, the EOC pin is set high, and the processing core goes
back to Idle state. The host processor can then perform the Data Read operation, which for I2C is simply a 7-byte
Device Read.
If the EOC pin is not monitored, the host can poll the Status Byte by repeating the Status Read command, which for
I2C is a one-byte Device Read. When the Busy bit in the Status byte is zero, this indicate that valid data is ready, and
a full Data Read of all 7 bytes may be performed.
DO NOT SEND COMMANDS TO SENSOR OTHER THAN THOSE DEFINED IN TABLE 1.
I2C Bus 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 mnemonics. 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.
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 DLH sensor has a preconfigured
slave address (see specification table on Page 3). 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 device-to master request (READ).

Table 2 - Output Data Format
I2C Interface (Cont’d)
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.
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.

SPI Interface
SPI Command Sequence
As with the I2C interface configuration, the part enters Idle state after power-up, and waits for a command from the
SPI master. To start a measurement cycle, one of the 3- byte Measurement Commands (see Table 1) must be issued
by the master.
The data returned by the sensor during this command request consists of the Status Byte followed by two undefined
data bytes.
On successful decode of the command, the EOC pin is set Low as the core goes into Active state for measurement
and calculation. When complete, updated sensor data is written to the output registers, and the core goes back to the
Idle state. The EOC pin is set to a High level at this point, and the Busy status bit is set to 0. At any point during the
Active or Idle periods, the SPI master can request the Status Byte by sending a Status Read command (a single byte
with value 0xF0).
As with the I2C configuration, a Busy bit of value 0 in the Status Byte or a high level on the EOC pin indicates that a
valid data set may be read from the sensor. The Data Read command must be sent from the SPI master (The first byte
of value 0xF0 followed by 6 bytes of 0x00).
NOTE: Sending commands that are not defined in Table 1 will corrupt sensor operation.
