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.

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.
www.allsensors.com
R
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.
R
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.
Signed Original On File
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.
R
The ADC performs conversions on the raw sensor signal (P), the temperature reference (T) and a zero reference (Z)
during the ADC measurement cycle.

The DLH 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.

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.

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 3-byte commands,
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.

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.

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).

START condition (ST): A HIGH to LOW transition of SDA line while the clock (SCL) is HIGH is interpreted as

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).
