2-4-2 I.CODE1Chip
(Philips Semiconductor IC, product name: SL1 ICS30 01, SL ICS31 01)
These specifications describe a Tag incorporating an IC chip I- CODE1
Label IC (product name: SL1 ICS30 01) 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 5-5 "System commands" for details.
OMRON defines the
blocks below Block 5 as the user memory area. Block 5 is page 00, 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 these specifications is in
accordance with OMRON's memory allocation scheme.

Page FF (Block 4)
Page FF (Block 4) can be used as user memory when Tag-discriminating access by Family Code (FC) or
Application ID (AI) is not performed. In this case, specify FF for the page to use it as user memory. The user
memory contains 12 pages.
