3. Custom Command

The IC manufacturing code is required to use a Custom command. The IC manufacturing code for the

MB89R119B is “08H”.

3-1. EAS command

On EAS command reception, the transponder returns the response code (“5AH”) repeated 6 times after the

specified flag (“00H”) if the EAS bit is “1” or returns no response if the EAS bit is “0”. The EAS command can

be executed only when the transponder is in the Ready state.



Request (from the reader/writer to the transponder)



Response (from the transponder to the reader/writer)

3-2. Write EAS command

On Write EAS command reception, the transponder writes the EAS bit into FeRAM.

The transponder performs verification after writing and returns an error code if the writing has failed.

The EAS bit must be set to “00H” to cancel anti-theft or goods-monitoring mode. The bit must be set to “01H”

as the EAS data to set up the goods-monitoring mode.

If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write

operation starting after “t1nom (320.9 s) + a multiple of 4096/fc (302.1 s)” with total tolerance of -32/fc to

+32/fc (2.4 s) and latest within 20 ms. If it is “1”, transponder shall wait for the reception of an EOF from

the reader/writer and upon such reception still return its response. (However, if an EOF is not sent within

38 ms, the time-out occurs and the transponder can receive another command.)
