1.2 TLE5014 satellite board
A satellite board is provided with a TLE5014D dual channel angle sensor which can be connected to the shield
of the Eval Kit. The TLE5014 on this board is pre-programmed with the following settings:
• SENT single secure sensor (incl. rolling counter and inverted nibble)
• UT=3.0 µs, pause pulse, no short serial message
The sensor is fully configurable and can be set to different protocol options and interfaces (SENT, SPC, PWM).
For a SPC bus mode:
• channel 1 has the default hard-wired address ID=0
• channel 2 has ID =1
It is possible to change the address by changing the “zero-ohm” resistors on the board (see figure and table
below).

4.3 Angle base calculation
For PWM/SPC protocol and SENT when feature error code “4091” is disabled
• Determine the position were “0°” should occur.
• Read out the 12-bit angle value at this position (in LSB).
• Multiply this value by 16.
• Write this (decimal) value in register 0x00A0Hand burn EEPROM.
• To change the rotation direction:
– Add “2” to this value in case bit[1] in 0x00A0His “0” and burn EEPROM again.
– Subtract “2” from this value in case bit[1] in 0x00A0His “1” and burn EEPROM again.
For SENT protocol when feature error code “4091” is enabled
• Determine the position were “0°” should occur.
• Read out the 12-bit angle value at this position (in LSB) -> LSB12’.
• Calculate: 4 * trunc[16384/4088 * (LSB12’ - 1)].
• Write this (decimal) value in register 0x00A0Hand burn EEPROM.
• To change the rotation direction:
– add “2” to this value in case bit[1] in 0x00A0His “0” and burn EEPROM again
– subtract “2” from this value in case bit[1] in 0x00A0His “1” and burn EEPROM again
4.4 SPC address configuration
If SPC in bus mode is used it is mandatory that the address of each sensor is written in the corresponding
EEPROM. This address must match with the address which is assigned via hardware pinout to this sensor.
Following values have to be written to address 0x00A4H:
• For ID = 0: 0x0400H
• For ID = 1: 0x0500H
• For ID = 2: 0x0600H
• For ID = 3: 0x0700H
Note: The bit [7:0] of register 0x00A4Hcontain the CRC for protecting the sensor configuration. After a
change of the configuration (e.g. angle base or SPC ID) is written to the EEPROM (EEPROM is burned)
the CRC is updated automatically.

4.5 Comments
If using SPC bus mode, the first step should be to write the corresponding SPC ID in address 0x00A4H
(Chapter 4.4).
The sensor comes with an enabled, default programmed look-up table (LUT) to reach the specified accuracy.
The default LUT values may not be changed as long as no own data are available. A change causes an
increased angle error.
The default values of the LUT can be overwritten in case own data are generated (for e.g. to correct for
magnetic circuit assembly tolerances).
If look-up table is used, the angle base correction (bit [15:2] of address 0x00A0H) has to be performed before
look-up table values are modified.
No other bits as the described may be changed as this could cause an unpredictable sensor behavior.
