2.6 Serial Interface
The communication and data transmission is based on a standard 16 bit serial peripheral interface (SPI). Figure 6 SPI timing
2.6.1 Commands
The following Commands are defined:
- Acquire identifier
- Acquire pressure (incl. the diagnosis pressure out of range, EEPROM check and last updated Diag1 & Diag2)
- Acquire temperature (incl. the diagnosis pressure out of range , EEPROM check and last updated Diag1 & Diag2)1)
- Trigger diagnosis (trig gers Diag1 and Diag2)
- Trigger test mode (entry into te st mode only occurs if this is the first command received after power up, in conjunction with a high voltage level (>10V) on pin VPROG)
2.6.1.1 Command Behavior
The SPI command interpretation is based on following rules:
- The response to command N is th e result of the previous command (N-1)
- The response to the first c ommand is the identifier
- When a command (N) is sent and the processing of the previous command (N-1) has not finalized, the last command (N) will not interrupt the processing
- Max. one command is stacked (du ring processing a command a new received command is stacked; further received commands will overwrite the stack)
- If a command has finished, the sensor takes the next command from the stack; if no command is in the stack, the sensor goes into the pressure measurement mode 1) Last updated diagnosis informa tion is only available if the Trigger diagnosis command was sent at any time before and the diagnostic reset is not active (Reset-bit C12 = ‘1‘, see Chapter 2.8.1).

Data Sheet 11 Revision 1.0, 2019-06-07 KP264 Digital Absolute Pressure Sensor Functional Description
- The diagnosis command triggers the Diag1 and Diag2 measurement; during this time pressure values (including out of range information) will not be updated
- Pressure and temperature values can be updated continuously based on a parallel acquisition
2.6.1.2 Structure
The following structure is defined for an SPI command: Figure 7 SPI command structure Figure 8 SPI response structure Figure 9 SPI response structure for identifier
2.6.1.3 Parity
Except for the identifier response (see Section 2.6.1.6) every SPI response (including the Communication Error response, see Section 2.6.1.5) includes an odd parity (LSB, [0]). The number of bits with the value one in the 16 bit response is odd (including the parity bit). 0123456789101112131415 \0\REQUEST RESET BIT ADDITIONAL REQUEST MSB LSB 0123456789101112131415 DATADIAGNOSIS PARIT Y MSB LSB 0123456789101112131415 ASIC NAMESUPPLIER MSB LSB SILICON VERSION METAL VERSION

2.6.1.4 Command Definition
Figure 10 Acquire pressure command Figure 11 Acquire temperature command Figure 12 Trigger diagnosis command Figure 13 Acquire identifier command Note: The Reset-bit (C12) determines how the diagnostic re set is handled. For details about the function of the Reset-bit refer to Chapter 2.8.1. The “trigger test mode” command is only for information. The te st mode is only for calibration and EEPROM programming. Both are already do ne during the supplier’s back-e nd assembly. The information should serve to avoid command for unintentional test mode operation. Note: Additional safeguards are provided to prevent unintentional test mode operation. For test mode operation, the command must be the first command after power-up in combination with a high voltage level at pin V PROG.

2.6.1.5 Communication Error
In normal operation only the pre ssure, temperature, diagnosis a nd identifier comman d s a r e v a l i d . E v e r y abnormality of these commands (e.g. unused command, other value of unused bits, number of clocks not equal to 16n with n = 1, 2, 3...) will r esult in a communication error. The response to a detected communication error is given below. Figure 15 Response after a communication error
2.6.1.6 Identifier Response Definition
The response to an Acquire identifier command is a fixed value as stated below. With this response, the KP264 sensor can be indentified when operated in a bus system with several different parts.

2.6.2 Single Device Operation
Figure 17 shows an example on how to connect a singe device to a microcontroller. After NCS is pulled to low, the request command is sent to the sensor with the next 16 cycles of the CLK. The response of the sensor for the pr evious request command is retu rned at the same time. The SPI signal timing is shown in Figure 18.

Data Sheet 15 Revision 1.0, 2019-06-07 KP264 Digital Absolute Pressure Sensor Functional Description
2.6.3 Daisy Chain Operation
The sensors can be connected to one SPI connection in daisy cha in operation to save micr ocontroller pins. The number of sensors connected in daisy chain operation is unlimited. Figure 19 Example for daisy chain operation Figure 19 shows an example of a combination of daisy chain mode and parallel operation. Note: Not all five sensors in this example could be addressed at once. Only one branch can be addressed at once (e.g. the KP26x_2.x branch). Finally only one NCS line can be low at the same time (NCS_S1, NCS_S2 or NCS_S3). The responding NCS line for the addressed sensor group must be low during the complete communication. During this time the provided number of clock pulses must be the multiplication result of 16 times the number of sensors in a daisy chain (e.g. 32 clock pulses for the KP26x_2.x branch in Figure 19). Figure 20 shows the whole signal diagram. It is important that NCS_S2.1 and NCS_S2.2 stay at the low level during the complete transmission. Therewith the sensor is able after receiving more than 16 clock pulses without a change in the NCS signal to switch automatically in daisy chain mode (in this example the first received 16 bit input data by the sensor S2.1 will be clocked to the output of sensor S2.1 with the last 16 clock pulses). µC MDO MDI CLK NCS_S1 NCS_S2 NCS_S3 KP26x_1.1 SDOSDI CLK NCS_S1 KP26x_2.1 SDOSDI CLK NCS_S2 KP26x_2.2 SDOSDI CLK NCS_S2 KP26x_3.2 SDOSDI CLK NCS_S3 KP26x_3.3 SDOSDI CLK NCS_S3 KP26x_3.1 SDOSDI CLK NCS_S3 NCS_S1 low for 16 CLK pulses NCS_S2 low for 32 CLK pulses NCS_S3 low for 48 CLK pulses
Data Sheet 16 Revision 1.0, 2019-06-07 KP264 Digital Absolute Pressure Sensor Functional Description Figure 20 Example for daisy chain signal diagram It is important that the number of clock pulses is a multiple of 16. Otherwise all commands for a daisy chain branch will be identified as invalid commands and the response of all sensors on this branch will be 01H.
2.7 Start-up Behavior
During the start-up phase (tstart-up), there is no response on any commands.
2.8 Diagnosis
The sensor is able to detect automatically the following malfunctions:
- Pressure out of range
- Signal path check (Diag1)
- Sensor cell check (Diag2)
- EEPROM check If a malfunction is detected, the responding diagnosis code is sent with the next response. Note: The Diag1 and Diag2 test can only be triggered by a separate SPI command. If more than one test fails, only that diagnosis code with the highest priority will be sent.

2.8.1 Diagnostic Reset
The Reset-bit (C12) of a SPI command allows using different reset strategies:
- C12 = ‘0‘: All detected failur es will be reset (with the exeption of FEC error
- C12 = ‘1‘: A detected f ailure will not be reset Reset of FEC error is not possible. Once FEC error is detected and transmitted it remains until supply reset.
2.8.1.1 Reset-bit C12 = ‘0‘
A detected failure is only trans mitted by the responding diagno sis code as long as the failure is present. The diagnosis code will be reset after once transmitted. Only if the failure is detected again, the diagnosis code will be transmitted again with the next response. Figure 21 Example for reset strategy Reset-bit C12 = ‘0‘
2.8.1.2 Reset-bit C12 = ‘1‘
Once a failure is detected the responding diagnosis code will be transmitted as long as:
- A failure with a higher priority is not detected
- The sensor is not reset (power down)
- Independent of the presence of the failure Table 4 Diagnosis codes Failure Priority Diagnosis Code EEPROM: FEC error 1 10000 Acquisition chain failure: Diag1 1)Note: This diagnosis code is not valid until a self diagnosis is triggered by sending the Trigger diagnosis command. 2 01000 Sensor cell failure: Diag21) 3 00100 P r e s s u r e o u t o f r a n g e : H i g h 4 00010 P r e s s u r e o u t o f r a n g e : L o w 5 00001 N o e r r o r 01010 time failure presence command diagnosis code response 01010 00001 00001 01010 e.g. pressure out of range : low pressure sampling

2.8.2 Pressure out of Range
The measured pressure is internally checked. If the pressure value falls below the lower limit or exceeds the higher limit the responding diagnosis code will be set. The limits are defined in Table 10 “Transfer function” on Page 25
2.8.3 Diag1
The Diag1 test checks the functionality of the signal path. Therefore the inputs of the sigma delta ADC are shorted. Afterwards, the system response is compared with the expected r ange (~ 50% of full scale range). If the system response is out of range, the diagnosis code is set. Figure 23 Diag1 functionality
2.8.4 Diag2
The Diag2 test checks the func tionality of the pressure sensor cells. Therefore a malfunction (e.g. broken membrane) can be detected. The KP264 pressure sensing element i s made of 2 measuring cells and 2 reference cells. In the normal mode these four cells are connected in a Wheatstone bridge configuration. In the Diag2 mode, the connection of the cells is modified as shown in Figure 24. time failure presence command diagnosis code response 01010 00001 00001 00001 e.g. pressure out of range : low pressure sampling ΣΔ ADC Decimation Filter
Data Sheet 19 Revision 1.0, 2019-06-07 KP264 Digital Absolute Pressure Sensor Functional Description Figure 24 Diag2 functionality
2.8.5 EEPROM Check
During the initialization phase, and after receiving a SPI comm and, the content of the EEPROM cells is copied into the corresponding EEPROM registers. Thereby, a parity check is done based on the parity row and column. A one bit error is corrected by the forward error correction. Any additional bit error results in an FECerror. In that case the diagnosis code 1 will be transmitted with the next response U = f (p) p p Normal Operation U = f (p) pp Diag2 Mode
