128bit OTP/RW Transponder
MLX90110 128bit MTP Transponder
Page 6 of 10
Rev 1.14 1-Dec-2000
When the transponder leaves the program mode
it enters the critical read mode when the address
counter is set to 4 or more. When a timeout
occurs before finishing to write the 4
th
word the
transponder returns to the corresponding write
mode, and waits for a new ACP.
CRITICAL READ MODE:
In the 'critical' read mode, all 9 words are
alternately read at the 2 extremes of the
EEPROM reading window.
When both readings are identical, the data
retention is guaranteed as specified (Tret, Ncyc).
If the two critical readings show a difference, the
device has been programmed marginally. It
should then be reprogrammed.
(TIP: Critical read failures can only occur when
the magnetic field strength is not kept constant
at Vacprh during the erase and write period after
the data have been sent to the transponder.)
The critical read latch is set after setting the
address counter to 4 (this is the address of word
5). The latch can only be reset by removing the
transponder from the field.
The MLX90110 has 2 different Write modes, for
which the same program and critical read modes
are applicable.
UNPROTECTED WRITE mode
(WP=0,RW=0)
The unprotected Write mode, is a Write mode in
which all 9 words can be programmed.
In normal (after POR) read mode all 9 words are
transmitted.
When the transponder detects the ACP it enters
program mode, without password protection.
The first SB will start the programmation cycle of
the first word, etc.
PROTECTED WRITE mode
(WP=0, RW=1)
The Protected Write mode, is a Write mode in
which only words 5, 6, 7 and 8 of the ID and the
configuration word 9 can be rewritten.
After POR the 8 words from the ID are
transmitted. Therefore it can be used together
with Transponders which have been set to Read
Only mode.
When the transponder detects the ACP it enters
program mode, with password protection.
The transponder will use its first 4 words as a
password. This avoids any hazardous erase, by
an occasional fluctuation of the external field,
which could be interpreted as an ACP followed
by a SB, for instance when the transponder is
removed from the field.
A password cycle is a programmation cycle in
which the 16bits sent by the reader should
match the data stored in the corresponding word
of the transponder. The word is not erased and
rewritten.
Remark that it is possible to program only one or
a few words by taking advantage of the timeout
option in the programming cycle.
READ ONLY Mode (WP=1, RW=x)
If the Write Protect bit is set (WP=1), the device
will not react to any modulation on the reader
antenna. It behaves like a regular Read Only
(RO) transponder, by continuously transmitting
its ID: 128bit from the first 8 words.
