1 Application Circuits

The application circuits in this chapter show the various communication possibilities of the TLE5014.

Figure 1 shows a basic application circuit of a TLE5014 with PWM interface. The pull-down resistor is required

to ensure that the sensor starts with a low level after power-on or reset (PWM starts with a rising edge). If the sensor is configured in such a way, that the PWM starts with a falling edge, the pull-down has to be replaced by a pull-up.

PWM

Figure 2 shows a basic application circuit of the TLE5014 with SPC mode.

Figure 2 Application circuit for TLE5014 with SPC, SPC address is configured to be “0” (IF1 and IF2

The circuit shows the minimum external circuit which is needed to operate the SPC interface. The generation of the trigger pulse (switch to pull the line low) is not shown. Depending on EMC requirements, additional circuitry may be required. The value of C

and Rp are specified in the datasheet.

The TLE5014 can also be used with a SENT interface (Figure 3). The circuit shown is according to the SAE J2716-2010 SENT specification.

Interfaces overview

2 Interfaces overview

Depending on the application, the TLE5014 is available with different interfaces:

• PWM (Pulse Width Modulation)

• SPC (Short PWM Code)

• SENT (Single Edge Nibble Transmission)

• SICI (Single-wire Interface for Calibration and Inspection; for programming purpose only)

PWM

The PWM is an unidirectional interface. Only one line is needed in which the angle value is transmitted. The angle value corresponds to the duty cycle of the signal data. A reserved duty cycle range is implemented which is used for indication of internal detected device errors. The data duty cycle range and the error duty cycle range can be programmed via EEPROM setting.

SPC

The SPC is an interface based on the SENT protocol. The ECU (master µC) sends a trigger pulse which triggers the TLE5014 to transmit the 12-bit angle value. If desired, the temperature can also be transmitted on a slow channel (short serial message). The SPC also sends a CRC nibble and an end-pulse to terminate the communication. One line is needed for the transmission and the pins IF1, IF2 and IFC are used to set the slave number. Up to four slaves can be connected to one ECU; the ECU trigger pulse length will trigger the respective sensor.

SENT

SENT is a standardized interface described in SAE J2716-2010.

SICI

A PWM based, bidirectional interface which is used for programming purpose only.

Further details on the SENT, SPC and PWM interface can be found in the data sheet of TLE5014.

2.1 PWM Interface Configuration

The following configuration of the PWM interface is possible. Further details are in the EEPROM register description in Chapter 4.

PWM starting edge 0x00A2 This value determines the starting edge of the PWM protocol.

It can be rising or falling. In case a rising edge is selected, the PWM protocol will start with a HIGH level. In case a falling edge is selected, it will start with a LOW

Care has to be taken when programming the low and high diagnostic duty cycle that there is no overlap with the programmed data duty cycle range. In such a case, diagnostic information (e.g. sensor failure) could not be distinguished from a valid transmitted angle value. It is recommended to add a safety margin between the diagnostic and the data duty cycle range.

2.2 SPC Interface Configuration

The following table shows the different options for SPC interface configuration. The details for the EEPROM setting are shown in Chapter 4.3

Description

SPC short serial message 0x00A2 A short serial message (slow message) can be activated,

which transmits one bit of a 16 bit information in each SPC frame and thus needs 16 SPC frames for the whole data transmission.This transmitted information is the programmed angle base and rotation direction, the chip temperature and 32 bit of the customer ID.

SPC unit time (UT) 0x00A2 The SPC unit time (UT) can be selected in the range of 1.0 µs

to 3.0 us.

SPC address setting in bus mode

The address of the sensor, so that it responds to a corresponding SPC trigger pulse, has to be set in the EEPROM. All parts delivered from Infineon have the default address of ID = 0 in the EEPROM. Please refer to description of EEPROM register 0x00A4 in Description EEPROM Address 0x00A4 CRC_CFG for correct setting. The address of the sensor written to the EEPROM must be identical to the address of the sensor defined via hard-wiring of the pins IF1, IF2 and IFC. Table 4 shows how the sensor address has to be set using the pins IF1, IF2, IFC.

SPC status nibble

The 4-bit status nibble of the SPC protocol has different content depending on SPC protocol configuration:

• No short serial message:

Table 5 SPC Status Nibble

Bit Description

0 (LSB) Sensor ID (LSB)

1Sensor ID (MSB)

2 Internal sensor failure

3 (MSB) Sensor reset or start-up (BIST) failure

• Short serial message (SSM) enabled:

Table 6 SPC Status Nibble

Bit Description

0 (LSB) Data bit of SSM

1 Start bit of SSM

2 Internal sensor failure

3 (MSB) Sensor reset or start-up (BIST) failure

In this configuration, the sensor ID is coded in the CRC and not available in the status nibble. There is also the option, that the rolling counter is not a dedicated nibble but the information is also coded in the CRC. Therefore, four different versions of the CRC calculation exist:

• No short serial message (SSM) and rolling counter as nibble Input data for the CRC calculation are: STATUS & DATA1 & DATA2 & DATA3 & ROLLING_CNT

• Short serial message (SSM) enabled and rolling counter as nibble the CRC calculation has to include a special 4-bit “ID-nibble” and is performed with the following input data: STATUS & DATA1 & DATA2 & DATA3 & ROLLING_CNT & ID_NIBBLE ID_NIBBLE = (0 0 ID(MSB) ID(LSB))

• Short serial message (SSM) is disabled and rolling counter is included in CRC (no rolling counter as nibble) The CRC calculation has to include a special 4-bit “RC-nibble” and is performed with the following input data: STATUS & DATA1 & DATA2 & DATA3 & RC_NIBBLE RC_NIBBLE = (RC(MSB) RC(LSB) 0 0)

• Short serial message (SSM) is enabled and rolling counter is included in CRC (no rolling counter as nibble) The CRC calculation has to include a special 4-bit “RC_ID-nibble” and is performed with the following input data: STATUS & DATA1 & DATA2 & DATA3 & RC_ID_NIBBLE RC_ID_NIBBLE = (RC(MSB) RC(LSB) ID(MSB) ID(LSB))

Synchronization of the Rolling Counter

The first transmitted SPC frame has a rolling counter value of 0. The next frame transmits a rolling counter value which is incremented by 1. In case the rolling counter is coded in the CRC, it is a 2-bit value. In this configuration, a synchronization of the counter value (sensor value and counter value in the micro controller) is required. The following two options are possible:

• Calculate the CRC with the received sensor data and a RC_NIBBLE of RC_NIBBLE = 0000

. Repeat this until

the calculated CRC matches with the transmitted CRC. This frame has the rolling counter value of 0. The next transmitted frame has the incremented counter value of 1 and so on. As the rolling counter has 2 bit in case it is coded in the CRC, latest the fourth transmitted frame needs to have a matched CRC. If this is not the case an error occurred.

• For the first transmitted frame, calculate the four possible CRCs with the RC_NIBBLE values 0000

to 0011B.

The CRC which is matching the transmitted CRC has the correct rolling counter value. Use this value as starting value which is incremented with the next received frame.

CRC calculation for SPC protocol

The checksum nibble is a 4-bit CRC of the data nibbles including the status nibble. The CRC is calculated using a polynomial x4+x3+x2+1 with a seed value of 0101

. The remainder after the last data nibble is transmitted as

CRC. The CRC calculation method is based on “recommended” implementation in the SENT standard 2010. For this “recommended” implementation, the CRC is calculated based on the input data which is then augmented with four extra zero bits and an additional CRC calculation step.

Code example:

//Table CRC, Poly=0xD uint8_t cr4Table[16] = {0, 13, 7, 10, 14, 3, 9, 4, 1, 12, 6, 11, 15, 2, 8, 5};

//Example: //Status Nibble = 0x6 //Data Nibble = 0x7, 0x4, 0x8, 0x7, 0x4, 0x8 uint8_t nibble[7] = {6, 7, 4, 8, 7, 4, 8}; uint8_t nb_nibble = 0x7;

compliant to the SENT specification

Standard SENT: Status nibble, 3 x 4-bit data nibbles, CRC nibble Single Secure SENT: Status nibble, 3 x 4-bit data nibbles, 2x4bit rolling counter; Inverted data nibble, CRC nibble

which transmits one bit of additional information in each SPC frame. This transmitted information is the programmed angle base and rotation direction, the chip temperature and 32 bit of the customer ID

only in the status nibble by setting an error bit or in the status nibble and also in the SENT data range. In this case an error code of “4091” is sent. For this option, the data range has not the full 12-bit resolution but only 1 … 4088 LSB

CRC calculation for SENT protocol

The checksum nibble is a 4-bit CRC of the data nibbles and does not include the status nibble (different to SPC CRC implementation). The CRC is calculated using a polynomial x4+x3+x2+1 with a seed value of 0101 remainder after the last data nibble is transmitted as CRC. The CRC calculation method is based on “recommended” implementation in the SENT standard 2010. For this “recommended” implementation, the CRC is calculated based on the input data (without STATUS nibble) which is then augmented with four extra zero bits and an additional CRC calculation step.

Code example:

//Table CRC, Poly=0xD uint8_t cr4Table[16] = {0, 13, 7, 10, 14, 3, 9, 4, 1, 12, 6, 11, 15, 2, 8, 5};

//Example: //Data Nibble = 0x7, 0x4, 0x8, 0x7, 0x4, 0x8 uint8_t nibble[6] = {7, 4, 8, 7, 4, 8}; uint8_t nb_nibble = 0x6; //Seed value = 0x5 uint8_t crc = 0x5;

. The

for(uint8_t i=0;i<nb_nibble;i++){ crc = nibble[i] ^ cr4Table[crc]; }

//Final XOR crc = 0x0 ^ cr4Table[crc];

The TLE5014 has an EEPROM as non-volatile memory where sensor configuration data can be stored. The memory is organized in pages, each page contains 8 registers, each register has 16 bit. Some pages and registers can be accessed by the user and the content can be modified thus changing chip configuration. Care has to be taken when modifying content of the EEPROM as the device behavior can be changed and no or wrong output data can be generated. There is no automatic restore functionality where the pre-programmed status can be recovered.

The EEPROM content is secured by a CRC. In case any content of the EEPROM is changed, the CRC has to be recalculated and written to the corresponding register, otherwise an error is indicated. The CRC has always be calculated out of several pages and registers, which are indicated in the description of the corresponding CRC (Table 10). The algorithm for the CRC calculation is described in Chapter 6.2.3.

The following Table 10 shows the pages and EEPROM registers of each page and their function. A detailed description of the EEPROM registers and the possible settings can be found in Chapter 4.

The startup value of each configuration register of the TLE5014 is stored in a corresponding EEPROM register, which can be modified by the user. Table 10 lists the allocation of the user-configurable EEPROM pages.

Care shall be taken when the EEPROM configuration is changed, as not all possible configurations are released by Infineon. This means, that they can be used for testing purpose but not necessarily for production. All released configurations can be found in the TLE5014 datasheet.
