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 Cwand Rpare 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.

GMR-Based Angle Sensor
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.

Interfaces overview
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
PWM diagnostic duty cycle high 0x0066 This value determines the duty cycle which indicates a
sensor reset or a sensor start-up error (BIST error)
PWM predevider for PWM period 0x0068 This value is used for PWM frequency adjustment according
to Equation (4.1)
PWM period 0x006A This value is used for PWM frequency adjustment according
to Equation (4.1)
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

Rolling counter in CRC 0x00A2 The rolling counter information can be coded in the CRC of
the SPC frame instead of being transmitted as extra nibble.
In this case the rolling counter information has 2 bit only.
This feature reduces overall frame length of the SPC protocol
SPC trigger 0x00A2 Two options are available for the total trigger length. It can
be constant with a length of 90 UT or variable. The variable
trigger length is tlow +12 UT and depends on the trigger low
time tlow. Both settings can be used in a bus configuration as
the address of the sensor is defined by the low time tlow only.
The advantage of the variable trigger length is that the total
frame length can be reduced

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.
Figure 4 shows a SPC frame with constant trigger length of 90UT, a status nibble, 3 data nibbles, a rolling
counter nibble and a CRC nibble. The low time of the trigger nibble determines the address of the sensor.

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

temperature and 32 bit of the customer ID.

to 3.0 us.

SPC status nibble
The 4-bit status nibble of the SPC protocol has different content depending on SPC protocol configuration:
• No short serial message:
• Short serial message (SSM) enabled:
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 = 0000B. 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 0000Bto 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 0101B. 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;

2.3 SENT Interface Configuration
The following table shows the different options for SENT interface configuration.
SENT Status Nibble
The 4-bit status nibble of the SENT protocol contains the following information:
Table 8 SENT Interface configuration
Parameter EEPROM
Register
Description
SENT low time 0x00A2 This value can be 5 UT or 3 UT. With 5 UT, the nibble is
compliant to the SENT specification
SENT protocol type 0x00A2 Two different SENT implementations can be configured:
Standard SENT: Status nibble, 3 x 4-bit data nibbles, CRC
nibble
Single Secure SENT: Status nibble, 3 x 4-bit data nibbles, 2x4-
bit rolling counter; Inverted data nibble, CRC nibble
Sent short serial message 0x00A2 A short serial message (slow message) can be activated
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
SENT error indication 0x00A2 In case of an internal chip error, the error can be indicated
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
Sent unit time (UT) 0x00A2 The SENT unit time (UT) can be selected in the range of 1.5 µs
to 3.0 us

Interfaces overview
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 0101B. 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 (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;
for(uint8_t i=0;i<nb_nibble;i++){
crc = nibble[i] ^ cr4Table[crc];
}
//Final XOR
crc = 0x0 ^ cr4Table[crc];

EEPROM Page Map
3 EEPROM Page Map
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.
