Table 5
Wafer number
Each wafer has a number between 1 and 25. This
5 bit wafer number contains the wafer number
where the IC was.
Factory reserved bits
These 4 bits are reserved. Default value is 0hex.
IC name bits
They contains the 3 first characters device name.
For this device, the value is 006hex.
Customer ID bits
This field contains a code which is defined by
EM Microelectronic-Marin S.A. For standard
version, the code is 0001hex.
Extended lot number
The code on the chips is unique and reflects the
production lot number system of EM
Microelectronic. This numbering allows full
traceability of each chip.
IC position
These 14 bits give the precise position on the
processed wafer.
Cyclic redundancy check
The shift register is reset to all zero with each
Stop Bit.
CRC code is calculated on 64 data bits. The CRC
code is calculated according to CCITT / ISO
3309 - 1984 standarts. See figure 5 for principle
block schematic and generating polynomial of
the CRC code.
Start and stop bits
Start bit is set to logic 1 and stop bit is set to logic
0.
