Crypto mode: the e5561 computes a response according to the challenge received
from the base station and sends the response to the base station
Stop mode: the e5561 stops modulation
An additional password function enables the e5561 to be operated only by a person who
knows the password programmed in the EEPROM memory.
Supply
The e5561 is supplied via a tuned LC circuit which is connected to Coil1 and Coil2 pads.
The incoming RF (actually a magnetic field) induces a current into the coil which powers
the chip. The on-chip rectifier generates the DC supply voltage (V
DD, VSS pads). Over-
voltage protection prevents the IC from damage due to high field strengths (depending
on the coil, the open-circuit voltage across the LC circuit can reach more than 100 V).
The first occurrence of RF triggers a power-on reset pulse, ensuring a defined start-up
state.
Start-up
The various modes of the e5561 are activated after the first read-out of the configura-
tion. The modulation is on during power-on reset and is off while the configuration is
read. After this initialization period of 128 + POR time FCs, the e5561 starts the auto-
matic adaptation of the resonance frequency. When the adaptation has been carried
out, the e5561 enters ID mode immediately if terminator 2 is selected, otherwise, a data
value of Fh in the selected configuration (modulation, bit rate) is sent followed by the
optionally specified terminator 1 (see Figure 8).
