OTP Functionality
If the OTP bit is set to ‘1’, all memory blocks are write protected and behave as if all lock
bits are set to 1. If the master key is set to ‘6’ additionally, the T5557 mode of operation
is locked forever (= OTP functionality).
If the master key is set to ‘9’, the test-mode access allows the re-configuration of the tag
again.

Table 4.
T5557 Types of Modulation in Extended Mode
Notes:
1. A common multiple of bitrate and FSK frequencies is recommended.
2. In PSK mode the selected data rate has to be an integer multiple of the PSK sub-carrier frequency.

FSK/5-/8
‘0’ = RF/5;
‘1’ = RF/8
FSK/8-/5
‘0’ = RF/8;

(= FSK1a)
FSK2
(1)
FSK/10-/8
‘0’ = RF/10; ‘1’ = RF/8
FSK/8-/10
‘0’ = RF/8;
‘1’ = RF/10

Phase change on rising edge of input
Phase change on falling edge of input
Manchester
‘0’ = falling edge, ‘1’= rising edge on mid-bit
‘1’ = falling edge, ‘1’= rising edge on mid-bit
Biphase 1 (’50)
‘1’ creates an additional mid-bit change
‘0’ creates an additional mid-bit change
Biphase 2 (’57)
‘0’ creates an additional mid-bit change
‘1’ creates an additional mid-bit change

‘1’= damping on, ‘0’= damping off
‘0’= damping on, ‘1’= damping off
