DLC - Compact High Resolution Pressure Sensors Series
Introduction
The DLC Series Compact High Resolution Sensor is based on
All Sensors’ CoBeam2 TM Technology. This reduces package
stress susceptibility, resulting in improved overall long term
stability. This technology breakthrough advances the state of
the art for piezoresistive pressure sensors beyond what has
been achieved for low pressure sensing using silicon based
strain technology. Design engineers will find exceptional
space savings with optimal performance for various compact
applications.
The low supply voltage allows for integration of the sen-
sors into a wide range of process control and measurement
systems, as well as direct connection to I2C serial com-
munications channels. The DLC series offers 16 bit digital
resolution. The digital interface options ease 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 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 and dry gases.

Output Resolution
Calibrated output resolution of 16 bits.
See the Data Update Time in the Performance Characteristics table.
The DLC is a digital sensor with a signal path that includes a sensing element, a variable- bit analog to digital con-
verter, a DSP and an IO block that supports an I2C 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.
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 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.
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.
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 appli-
cation. For longer fixed reading intervals, this shift may be removed by the factory on special request.

When requesting sensor status over I2C, the host simply performs a 1-byte read transfer.
When reading sensor data over I2C, the host simply performs a 7-byte read transfer.

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.
Note that a completed reading without error will return status 0x40.
Table 2 - Output Data Format
Table 3- 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 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.

I2C Interface (Cont’d)
Figure 3 - I2C Communication Diagram
Page 9
I2C Bus Communications Overview
The I2C interface uses a set of signal sequences for communication. The following is a description of the sup-
ported 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.
Slave address (An): The I²C-bus requires a unique address for each device. The DLC 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).
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 con-
dition. STOP conditions are always generated by the master.

Descrip�on
All products are labeled via laser marking as seen in Figure 5.
Figure 6 details how to interpret the part marking code. Low pressure ranges from 1 to 60 inH2O are specified with
code “L” and 5 to 150 psi high pressure products with code “H”.
The pressure range will be indicated on the same line as the wafer number before the starting character “B”.
