INTERFACING TO TE
DIGITAL PRESSURE
MODULES
The TE series of digital pressure sensors uses the latest CMOS sensor
conditioning circuitry (SSC) to create a low cost, high performance digital output
pressure (14-bit) and temperature (11-bit) sensor designed to meet the strictest
requirements from OEM customers.
The MS45x5DO, 85BSD, 85FBSD, 86BSD,154BSD, MSP100(DO) and
MSP300(DO) are the latest offering from TE to offer digital communication to
pressure sensor OEMs.
I2C AND SPI INTERFACE SPECIFICATIONS
1. I2C Interface Specification
The I2C interface is a simple 8-bit protocol using a serial data line (SDA) and a serial clock line (SCL) where each device connected to the
bus is software addressable by a unique address. For detailed specifications of the I2C protocol, see The I2C Bus Specification, Version 2.1,
January 2000.
1.1 Interface Connection-External
Bi-directional bus lines are implemented by the devices (master and slave) using open-drain output stages and a pull-up resistor connected
to the positive supply voltage. The recommended pull-up resistor value depends on the system setup (capacitance of the circuit or cable and
bus clock frequency). In most cases, 4.7kΩ is a reasonable choice. The capacitive loads on SDA and SCL line have to be the same. It is
important to avoid asymmetric capacitive loads.
02/2021
SENSOR SOLUTIONS ///M3200
Page 11
M3200
Pressure Transducer
1.2 I2C Address
The I2C address consists of a 7-digit binary value. The factory setting for the I2C slave address is 0x28, 0x36 or 0x46 depending on the
interface type selected from the ordering information. The address is always followed by a write bit (0) or read bit (1). The default
hexadecimal I2C header for read access to the sensor is therefore 0x51, 0x6D, 0x8D respectively, based on the ordering information.
1.3 INT/SS Pin
When programmed as an I2C device, the INT/SS pin operates as an interrupt. The INT/SS pin rises when new output data is ready and falls
when the next I2C communication occurs.
1.4 Transfer Sequences
Transmission START Condition (S): The START condition is a unique situation on the bus created by the master, indicating to the slaves
the beginning of a transmission sequence (the bus is considered busy after a START).
I2 C Transmission Start Condition
SDA
SCL
START condition
A HIGH to LOW transition on the SDA line while SCL is HIGH
Transmission STOP Condition (P): The STOP condition is a unique situation on the bus created by the master, indicating to the slaves the
end of a transmission sequence (the bus is considered free after a STOP).
I2 C Transmission Stop Condition
SDA
SCL
STOP condition
A LOW to HIGH transition on the SDA line while SCL is HIGH
Acknowledge (ACK) / Not Acknowledge (NACK): Each byte (8 bits) transmitted over the I2C bus is followed by an acknowledge condition
from the receiver. This means that after the master pulls SCL low to complete the transmission of the 8th bit, SDA will be pulled low by the
receiver during the 9th bit time. If after transmission of the 8th bit the receiver does not pull the SDA line low, this is considered to be a NACK
condition.
02/2021
SENSOR SOLUTIONS ///M3200
Page 12
M3200
Pressure Transducer
If an ACK is missing during a slave to master transmission, the slave aborts the transmission and goes into idle mode.
I2 C ACKNOWLEDGE / NOT ACKNOWLEDGE
Each byte is followed by an acknowledge or a not
acknowledge, generated by the receiver
1.5 Data Transfer Format
Data is transferred in byte packets in the I2C protocol, which means in 8-bit frames. Each byte is followed by an acknowledge bit. Data is
transferred with the most significant bit (MSB) first.
A data transfer sequence is initiated by the master generating the Start condition (S) and sending a header byte. The I2C header consists of
the 7-bit I2C device address and the data direction bit (R/_W).
The value of the R/_W bit in the header determines the data direction for the rest of the data transfer sequence. If R/_W = 0 (WRITE), the
direction remains master-to-slave, while if R/_W = 1 (READ), the direction changes to slave-to-master after the header byte.
1.6 Command Set and Data Transfer Sequences
The I2C master command starts with the 7-bit slave address with the 8th bit = 1 (READ). The sensor acts as the slave and sends an
acknowledge (ACK) indicating success. The sensor has four I2C read commands: Read_MR, Read_DF2, Read_DF3, and Read_DF4.Figure
1.6 shows the structure of the measurement packet of the four I2C read commands, which are explained in sections 1.6.1.

SENSOR SOLUTIONS ///M3200
Page 13
M3200
Pressure Transducer
1.6.1
Figure 1.6 – I2C Measurement Packet ReadsI2C Read_DF (Data Fetch)
For Data Fetch commands, the number of data bytes returned by the sensor, is determined when the master sends the NACK and stop
condition. For the Read_DF3 data fetch command (Data Fetch 3 Bytes; see example 3 in Figure 1.6), the sensor returns three bytes in
response to the master sending the slave address and the READ bit (1): two bytes of bridge data with the two status bits as the MSBs and
then 1 byte of temperature data (8-bit accuracy). After receiving the required number of data bytes, the master sends the NACK and stop
condition to terminate the read operation. For the Read_DF4 command, the master delays sending the NACK and continues reading an
additional final byte to acquire the full corrected 11-bit temperature measurement. In this case, the last 5 bits of the final byte of the packet
are undetermined and should be masked off in the application. The Read_DF2 command is used if corrected temperature is not required.
The master terminates the READ operation after the two bytes of bridge data (see example 2 in Figure 1.6).
The two status bits (Bit 15 and Bit 14) give an indication of stale or valid data depending on their value. A returned value of 00 indicate
“normal operation and a good data packet” while a returned value of 10 indicates “stale data that has been already fetched”. See section 1.7
for additional details. Users that use “status bit” polling should select a frequency slower than 20% more than the update time.

1.7 Status Bits and Diagnostic Features

Stale Data. Data has been fetched since last measurement cycle.
Fault Detected
The SSC is has on board diagnostic features to ensure robust system operation in the most “mission-critical” applications. A status bit value
of “11” indicates a fault condition in the SSC or sensing element. All diagnostics are detected in the next measurement cycle and reported in
the subsequent data fetch. Once a diagnostic is reported, the diagnostic status bits will not change unless both the cause of the diagnostic is
fixed and a power-on-reset is performed.
1.8 I2C Protocol Differences
There are three differences in the described above protocol compared with original I2C protocol:
◼
Sending a start-stop condition without any transitions on the SCL line (no clock pulses in between) creates a communication error for
the next communication, even if the next start condition is correct and the clock pulse is applied. An additional start condition must be
sent, which results in restoration of proper communication.
◼
◼
The restart condition – a falling SDA edge during data transmission when the SCL clock line is still high – creates the same situation.
The next communication fails, and an additional start condition must be sent for correct communication.
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 down from the start condition through the first bit.
2. SPI Interface Specification
SPI is a general-purpose synchronous serial interface. During an SPI transfer, transmit and receive data is simultaneously shifted out and in
serially. A serial clock line synchronizes the shifting and sampling of the information on two serial data lines.
SPI devices communicate using a master-slave relationship. Due to its lack of built-in device addressing, SPI requires more effort and more
hardware resources than I2C when more than one slave is involved. But SPI tends to be simpler and more efficient than I2C in point-to-point
(single master, single slave) applications for the very same reason; the lack of device addressing means less overhead.
The SPI interface is programmed for falling-edge MISO change.

2.1 SPI Read_DF (Data Fetch)
The SPI interface will have data change after the falling edge of SCLK. The master should sample MISO on the rise of SCLK. The entire
output packet is 4 bytes (32 bits). The high bridge data byte comes first, followed by the low bridge data byte. Then 11 bits of corrected
temperature (T[10:0]) are sent: first the T[10:3]byte and then the {T[2:0],xxxxx} byte. The last 5 bits of the final byte are undetermined and
should be masked off in the application. If the user only requires the corrected bridge value, the read can be terminated after the 2nd byte. If
the corrected temperature is also required but only at an 8-bit resolution, the read can be terminated after the 3rd byte is read.
Packet = [ {S(1:0),B(13:8)},{B(7:0)},{T(10:3)},{T(2:0),xxxxx}] Where
S(1:0) = Status bits of packet (normal, command, busy, diagnostic)
6 bits of 14-bit bridge data.
B(13:8) = Upper
B(7:0) = Lower 8 bits of 14-bit bridge data.
T(10:3) = Corrected temperature data (if application does not require corrected temperature, terminate read early)
Remaining bits of corrected temperature data for full 11-bit resolution
HiZ = High impedance
T(2:0),xxxxx =.
