3-2-1-1 I-CODE1 Chip (Philips IC product name : SL1 ICS30 01, SL1 ICS31 01)
1) Memory Map of I-CODE1
These specifications describe a Tag incorporating an IC chip I- CODE1 Label IC from Philips, which is accessed by the system. This chip consists of a 64-byte memory. The upper five blocks (Blocks 0 to 4) of the memory are used as a system area having functions that do not relate to user memory. OMRON offers special commands for accessing this area in order to ensure the great ease of these functions by the user. Refer to Command List for details. OMRON defines the blocks below Block 5 as the user memory area. Block 5 is page 00h, and the subsequent blocks are allocated as shown below. The memory is organized with four bytes as one page (4 bytes = 32 bits). One page is the minimum unit that can be read from and written to the memory. The memory allocation described in this user's manual is in accordance with OMRON's memory allocation scheme.

Section 3-2
The system area of I-CODE1 is mapped onto the memory. OMRON allocates the system area to pages B Hex to F Hex.
SNR is a tag-specific code and has been written into the memory during the chip production process. The R/W Module is shipped with this page write -access inhibited (refer to page D Hex ); there is no way of making this page rewritable by the user.
The pages are write-inhibited permanently if they are so indicated in the memory map. The factory settings are as follow. If the two bits of a particular page are 0.0, that page is write-protected.

Tag Access Functions
3-2-2 Single Access and FIFO Access Functions
Single Access Mode
Use this mode to communicate with only one tag within the R/W Module communications area. The time required for communications with the tag is shorter compared with FIFO access mode.
FIFO Access Mode
FIFO (First In First Out) access mode enables reading tags in order as they enter the antenna communications range. Tags with which communications have been completed are prohibited from being accessed again, so even if tags with which communications have been completed are still within range of the antenna, communications will be possible with new tags as they enter the communications range. When two or more tags enter the antenna communications range at the same time, a communications error will occur. When a tag to which access has been prohibited moves out of the communications area, communications with it will be possible again if it reenters the antenna communications range.
The above diagram shows an example of a tag inspection line. When the distance between tags is small, two tags may enter the R/W Module communications range at the same time. If this happens when in Single Access Mode, a communications error will occur, or even if read/write appears to have been performed, there is no way to know which of the two tags was read. In FIFO Access Mode, tags entering communications range can be read or written to in order, so this mode is suited to applications such as a tag inspection line, in which the order of access is important.

Tag Access Functions
3-2-3 Lock Function
Note The lock function used with the V720 Series cannot be canceled. Pages that have been
write-protected cannot be written to again, so be careful when using this function.
Section 3-2
The lock function is a protection function provided to prevent the loss of data by unintentionally overwriting fixed data stored on the tags. This function can be set using the lock command. This function can be set using the lock command.
There is a lock setting area in the tag system area, enabling user-defined areas to be write-protected one page at a time. If the write command is executed for a page that has been write-protected, a write processing error will occur.

3-2-4 Tag Identification Access Function
Only when the ID code stored on the tag and the ID code included in the command sent from the antenna match will the tag respond. This is called the tag identification access function.
Commands sent from the R/W Module respond without depending upon the ID code stored in the tags.
Reference Information for I-CODE1
An example of using tag ID access using OMRON V720-H01 R/W Antenna and V720-CD1D is given below.
(1) The set values of the tag ID codes are given in the following table. These settings can be made using the

and a response is sent. If there is no tag in communications range, a No Tag error is sent. After the response has been sent, the mode changes to sleep mode. Only one tag is permitted in communications range.
After a command is received, this mode waits for a tag to enter communications range, and then performs communications with the tag. After the response has been sent, the mode changes to sleep mode. If a STOP command is received while waiting for a tag, the command is ended. Only one tag is permitted in communications range. After a command is received, this mode waits for a tag to enter communications range, and then performs communications with the tag. If this mode has been specified, the command is repeated sequentially until a STOP command is received. This mode is enabled only for read commands. Only one tag is permitted in communications range.
After a command is received, communications with the tag is performed immediately and a response is sent. If there is no tag in communications range, a No Tag error is sent. Access is prohibited to tags with which communications have been completed, and the R/W Module continues unmodulated oscillation. Tags with which commu nications have been completed do not respond to the next command. After the response has been sent, the mode changes to sleep mode. If a STOP command is received, oscillation stops.

3) Write identical data
Use this command to write identical data to tags by the page. Data can be written to user- specified pages (except B Hex to E Hex for I -CODE1). This command is useful when writing the same data to multiple pages.
The maximum number of pages which can be written to in a single operation is one bank, and writing to pages across banks is impossible.
There is no need to perform the verify read process, since this command performs it as part of its execution.
n Command
As parameters, the command sends specification of the pages to be written and the data to write to the specified pages one page at a time. The page specification is as follows: The bits that correspond to the pages to be written are set to 1, and all other bits are set to 0. This binary number is converted to hexadecimal and sent with the command. The write data is specified sequentially in ascending order of the pages specified. In the case of a Tag equipped with I -CODE1, specify the write data in the order: F01···A.

3) Write identical data
Use this command to write identical data to tags by the page. Data can be written to user- specified pages (except B Hex to E Hex for I-CODE1). This command is useful when writing the s ame data to multiple pages
The maximum number of pages which can be written to in one operation is one bank, and writing to pages across banks is impossible. There is no need to perform the verify read process, since this command performs it as part of its execution.
n Command
As parameters, the command sends specification of the pages to be written and the data to write to the specified pages one page at a time. The page specification is as follows: The bits that correspond to the pages to be written are set to 1, and all other bits are set to 0. This binary number is converted to hexadecimal and sent with the command. The write data is specified sequentially in ascending order of the pages specified. In the case of a Tag equipped with I -CODE1, specify the write data in the order: F⇒0⇒ 1⇒···⇒A.

Communications Time (Reference)
Example: Reading data from pages 1, 5, and 9
T = 1.3 × ( 9 - 1 + 1 ) + 6.2 = 17.9 ms (for I-CODE1) T = 1.3 × (9 - 1 + 1 ) + 6.0 = 17.7 ms (for I-CODE2)
Example: Reading data from pages C, 5, and 9
T = 1.3 × (9-(-4)+1) + 6.2 = 24.4ms (for I-CODE1) T = 1.3 × (12-5+1) + 6.0 = 16.6ms (for I-CODE2)
Example: Writing data to pages 2, 4, 9, and 10
T = 11.7 × 4 + 1.3 × ( 10 - 2 + 1 ) + 13.5 = 72ms (for I-CODE1) T = 12.3 × 4 + 1.3 × ( 10 - 2 + 1 ) + 15.5 = 76.4ms (for I-CODE2)
Communications Time Calculation Conditions
Communications mode: Single Trigger Mode
Communications errors must not occur, such as due to noises.

Communications Time (Reference)
5-3-2 TAT (Turn Around Time)
The TAT is the time taken from when the host control unit sends a command to the R/W Module, to when a response is received and completed.
The time differs depending on the baud rate and the communications control method setting.
Example of TAT Calculation
Example: Reading from page 0 to page 4
I-CODE1 I-CODE2 (1)During command send 9[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] 10.32ms
(2)During communications
6.5 + 6.2 = 12.7ms
(3)During reception of response 43[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] 49.27ms
The TAT in to the above example is (1) + (2) + (3) = 72.29 ms.
Section 5-3
(1)During command send 11[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] 12.61ms
(2)During communications
6.5 + 6.0 = 12.5ms
(3)During reception of response 43[char.] × 11 [bits] / 9600[bps] × 1000[ms/s] 49.27ms
The TAT in to the above example is (1) + (2) + (3) = 74.38 ms.
The calculations are performed according to the following conditions.
Communications mode : Single Trigger Mode
Communications control method : CR control
Baud rate : 9,600 bps
Data code specification : Hexadecimal
Commands sent from the host control unit are sent continuously without spaces between the
characters.
Communications errors must not occur, such as due to noises.
