COMMAND

This LSI supports all mandatory commands and parts of optional commands defined by EPCglobal C1G2

Ver. 1.2.0. (Chapter 6.3.2.11). The commands list and codes are shown in the table below.

For BlockWrite and BlockErase command (Optional command), parts of the specifications are different from

the EPC C1G2 standard as described in “(1)BlockWrite (Optional command)” and “(2)BlockErase (Optional

command)”.

• Command

• CRC-16(Differences from EPCglobal C1G2 Ver. 1.2.0)

When the R/W writes the entire or part of the PC or EPC area of the Tag, CRC-16 stored in EPC memory

00H to 0FH of the Tag is disabled until an ACK command is received and a response that is not truncated

(PC, EPC, CRC-16) is returned. After the completion of responding to ACK command, the correct CRC-16

value calculated during responding is written to EPC memory (00H to 0FH) as well. If a truncated response

to the ACK command is requested before CRC-16 is enabled, the CRC-16 value in the EPC memory, which

has not been enabled, is returned as is.
