PART IDENTIFICATION
Two registers mapped into the MMR space are intended to
allow user code to identify and trace manufacturing lot ID
information, part ID number, silicon mask revision, and kernel
revision. This information is contained in the SYSSER0 and
SYSSER1 MMRs. See Table 99 and Table 100 for details.
For full traceability, the part assembly lot number, SYSSER0,
and module number need to be recorded. The lot number is
part of the branding on the package as shown Table 98.

Silicon revision and kernel revision information is contained in
the MMRs, SYSSER1, and FEE0ADR.
System Serial ID Register 0
Name: SYSSER0
Address: 0xFFFF0238
Default Value: 0x00000000 (updated by kernel at power-on)
Access: Read/write
Function: At power-on, this 32-bit register holds the value of the original manufacturing lot number from which this specific
ADuC7033 unit was manufactured (bottom die only). Used in conjunction with SYSSER1, this lot number allows the
full manufacturing history of this part to be traced (bottom die only).

Bit Description
31 to 27
Wafer Number. The five bits read from this location give the wafer number (1 to 24) from the wafer fabrication lot ID
(from which this device originated). When used in conjunction with SYSSER0[26:0], it provides individual wafer
traceability.
26 to 22
Wafer Lot Fabrication Plant. The five bits read from this location reflect the manufacturing plant associated with this
wafer lot. When it is used in conjunction with SYSSER0[21:0], it provides wafer lot traceability.
21 to 16
Wafer Lot Fabrication ID. The six bits read from this location form part of the wafer lot fabrication ID, and used in
conjunction with SYSSER0[26:22] and SYSSER0[15:0], provides wafer lot traceability.
15 to 0
Wafer Lot Fabrication ID. These 16 LSBs hold a 16-bit number to be interpreted as the wafer fabrication lot ID number.
When used in conjunction with the value in SYSSER1, that is, the manufacturing lot ID, this number is a unique identifier
for the part.
