Figure 1. Transponder System Example Using e5561
Internal Modes
The e5561 can be operated in several internal modes, each providing a special function.
These are:
Start-up
ID mode
Programming mode
Direct-access mode
Crypto mode
Stop mode
Password function
The following section gives a short functional description of each mode. A more detailed
description is given in the section "Operating the e5561".
Start-up
After the Power-On Reset (POR) has reset the entire circuit, the e5561 is configured by
reading out the configuration data bits of the EEPROM.
ID Mode
During ID mode, the e5561 transmits an identification data stream (ID code) to the base
station. As the base station reads out data coming from the transponder, this direction of
data transmission will be designated as ’read’.
The ID code is sent in loop as long as the RF field is applied. The single parts of the data
stream and the type of modulation depend on the configuration loaded during start-up.
The following options are available during ID mode:
Two different bit rates and modulations
Two possible lengths of the ID code (64 bits or 128 bits)
Two different terminators
A 4-bit preburst followed by terminator 1 between start-up and sending the first data
bits of the ID code
Programming Mode
The e5561 must be programmed before being used in a security system. The e5561
contains a 320-bit EEPROM which is arranged in 10 blocks of 32 bits each. Program-
ming the e5561 is carried out blockwise, i.e., every single block has to be programmed
separately. The blocks of the EEPROM are divided into 4 sections:
