TEB Components for the MPR Series Total Error Band (TEB) is a single specification that includes the major sources of sensor error. TEB should not be confused with accuracy, which is actually a component of TEB. TEB is the worst error that the sensor could experience. Honeywell uses the TEB specification in its datasheet because it is the most comprehensive measurement of a sensor’s true accuracy. Honeywell also provides the accuracy specification in order to provide a common comparison with competitors’ literature that does not use the TEB specification. Many competitors do not use TEB—they simply specify the accuracy of their device. Their accuracy specification, however, may exclude certain parameters. On their datasheet, the errors are listed individually. When combined, the total error (or what would be TEB) could be be significant. ## **Sources of Error** |**Sources of Error**|| |---|---| |Offset|**Total**<br>**Error**<br>**Band**<br>**Accuracy**<br>**BFSL**| |Full Scale Span|| |Pressure Non-Linearity|| |Pressure Hysteresis|| |Pressure Non-Repeatability|| |Thermal Effect on Offset|| |Thermal Effect on Span|| |Thermal Hysteresis|| Table 1.

The MPR Series sensor can begin the first measurement after 2.5 ms from when the VDD supply is operational. Alternatively, instead of a power-on reset, a reset and new power-up sequence can be triggered by an IC-reset signal (high low) at the RES pin. ## 1.2 Power Supply Requirement Verify that system power to the sensor meets the VDD rising slope requirement (minimum VDD rising slope is at least 10 V/ms). If not, use the RES pin to bring the sensor out of reset once the system power has stabilized. ## 1.3 I[2] C and SPI Reference Circuits (see Figure 3) ## Figure 3.

The I[2] C bus is a simple, serial 8-bit oriented computer bus for efficient I[2] C (Inter-IC) control. It provides good support for communication between different ICs across short circuit-board distances, such as interfacing microcontrollers with various low speed peripheral devices. For detailed specifications of the I[2] C protocol, see Version 2.1 (January 2000) of the I[2] C Bus Specification (source: NXP Semiconductor at https://www.nxp.com/docs/en/user-guide/UM10204.pdf). Each device connected to the bus is software addressable by a unique address and a simple Master/Slave relationship that exists at all times. The output stages of devices connected to the bus are designed around an open collector architecture. Because of this, pull-up resistors to +VDD must be provided on the bus. Both SDA and SCL are bidirectional lines, and it is important to system performance to match the capacitive loads on both lines. In addition, in accordance with the I[2] C specification, the maximum allowable capacitance on either line is 400 pF to ensure reliable edge transitions at 400 kHz clock speeds. When the bus is free, both lines are pulled up to +VDD[.] Data on the I[2] C bus can be transferred at a rate up to 100 kbit/s in the standard-mode, or up to 400 kbit/s in the fast-mode. ## Figure 4.

Following the address and read bit from the Master, the MPR Series sensors are designed to output up to 4 bytes of data. The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). ## 2.3 I[2] C Sensor Address Each MPR Series I[2] C sensor is referenced on the bus by a 7-bit slave address. The default address for the MPR Series is 24 (0x18). Other available standard addresses are: 08 (0x08), 40 (0x28), 56 (0x38), 72 (0x48), 88 (0x58), 104 (0x68), 120 (0x78). (Other custom values are available. Please contact Honeywell Customer Service with questions regarding custom Slave addresses.) ## 2.4 I[2] C Pressure Reading (See Table 9.) To read out a compensated pressure reading, the Master generates a START condition and sends the sensor Slave address followed by a read bit (1). After the sensor generates an acknowledge, it will transmit up to 4 bytes of data. The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). The Master must acknowledge the receipt of each byte, and can terminate the communication by sending a Not Acknowledge (NACK) bit followed by a Stop bit after receiving the required bytes of data. 10 sensing.honeywell.com MicroPressure Board Mount Pressure Sensors, MPR Series ## 2.5 I[2] C Status Byte (See Table 9.)

It operates either in full-duplex or half-duplex mode, allowing communication to occur in either both directions simultaneously, or in one direction only. The Master device initiates an information transfer on the bus and generates clock and control signals. Slave devices are controlled by the Master through individual Slave Select (SS) lines and are active only when selected. The MPR Series SPI sensors operate in full-duplex mode only, with data transfer from the Slave to the Master. This data transmission uses four, unidirectional bus lines. The Master controls SCLK, MOSI and SS; the Slave controls MISO. (See Figure 6.) 12 sensing.honeywell.com ## MicroPressure Board Mount Pressure Sensors, MPR Series Figure 6.

At this point, the sensor is no longer idle, and will begin sending data once a clock is received. MPR Series SPI sensors are configured for SPI operation in mode 0 (clock polarity is 0 and clock phase is 0). (See Figure 7.) ## Figure 7. Example of 1 Byte SPI Data Transfer **==> picture [542 x 136] intentionally omitted <==** **----- Start of picture text -----**<br> SCLK<br>MOSI MSB Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 LSB<br>MISO MSB Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 LSB<br>SS<br>**----- End of picture text -----**<br> Once the clocking begins, the MPR Series SPI sensor is designed to output up to 4 bytes of data. The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). ## 3.3 SPI Pressure Reading To read out a compensated pressure reading, the Master generates the necessary clock signal after activating the sensor with the Slave Select (SS) line. The sensor will transmit up to 4 bytes of data. The first data byte is the Status Byte (8-bit) and the second to fourth bytes are the compensated pressure output (24-bit). The Master can terminate the communication by stopping the clock and deactivating the SS line.

Pmax. - Pmin. Rearranging this equation to solve for Pressure, we get Equation 2: ## Equation 2: Pressure Output Function Pressure = (Output - Outputmin.) * (Pmax. - Pmin.) + Pmin. Outputmax. - Outputmin. Where: Outputmax. = output at maximum pressure [counts] Outputmin. = output at minimum pressure [counts] Pmax. = maximum value of pressure range [bar, psi, kPa, etc.] Pmin. = minimum value of pressure range [bar, psi, kPa, etc.] Pressure = pressure reading [bar, psi, kPa, etc.] Output = digital pressure reading [counts] Example: Calculate the pressure for a -1 psi to 1 psi gage sensor with a 10% to 90% calibration, and a pressure output of 14260634 (decimal) counts: Outputmax. = 15099494 counts (90% of 2[24] counts or 0xE66666) Outputmin. = 1677722 counts (10% of 2[24] counts or 0x19999A) Pmax. = 1 psi Pmin. = -1 psi Pressure = pressure in psi Output = 14260634 counts Pressure = (14260634-1677722) * (1 - ( - 1)) + (-1) 15099494 - 1677722[ ] Pressure = 25165824 + (-1) 13421772 Pressure = 0.875 psi 16 sensing.honeywell.com MicroPressure Board Mount Pressure Sensors, MPR Series Figure 9.
