The low supply voltage allows for integration of the sensors into a wide range of process control and measurement
systems, as well as direct connection to I2C serial communications channels. The DLC series offers 16 bit digital
resolution. The digital interface options ease integrationof the sensors into a wide range of process control andmeasurement systems, allowing direct connection to serial
communications channels. For battery-powered systems, thesensors 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.

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 DLC series compact package sizes startas small as 7mm x 7mm and the product family’s low costmakes it the perfect solution for applications that requirevery low prices with high volume.

Soldering Recommendations
1) Solder parts as a second operation only.
2) Post reflow and other high temperature processes, wait for 48 hrs before performing any calibration operations.
3) Perform spot cleaning as necessary only by hand. DO NOT wash or submerge device in cleaning liquid.
4) Max 270°C lead temperature (soldering 2-4 sec.)
If these devices are to be subjected to solder reflow assembly or other high temperature processing, they must
be baked for 1 hour at 125°C within 24 hours prior to exposure. Failure to comply may result in cracking and/or
delamination of critcal interfaces within the package, and is not covered by warranty.

Device Ordering Options

Operation Overview
The DLC 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 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.

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 theappropriate 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 using the Start-Average4 measurement command. This
results in the best combination of low noise and offset accuracy. For applications requiring different reading modes,
such as infrequent single readings, there may be a small constant value of offset shift. This shift can be measured at
system startup, and can be removed by the application.

DS-0365 Rev B

p 408 225 4314

The DSP receives the converted pressure and temperature information and applies a multi-order transfer function tocompensate 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 alsolinearity 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.

Digital Interface Data Format

all sensors

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 3- Status Byte Definition

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, whichfor I2C is a one-byte Device Read. When the Busy bit in the Status byte is zero, this indicate that valid data isready, and a full Data Read of all 7 bytes may be performed.

I2C Interface (Cont’d)
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 tobegin 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 forduration 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.

Product Identification on backside of device
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 withcode “L” and 5 to 150 psi high pressure products with code “H”.
