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
The following
Table 10
description of the EEPROM registers and the possible settings can be found in
The startup value of each configuration register of the TLE5014 is stored in a corresponding EEPROM register,
which can be modified by the user.
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.
