DS2401 Silicon Serial Number
Communication to a DS2401 Silicon Serial Number can be imple-
mented in various software applications for the definition of a node
address or as copy protection in networked applications. The DS2401
can be soldered on space U10 or U9 on the Development Board,
depending on the type of device packaging being used.
The Silicon Serial Number Chip mounted on the phyCORE
Development Board LD 5V can be connected to a port pin at
GPIO1 (JP19 1+2) or the data bus via latch U14 and driver
U15 (JP19 = 2+3). When using the phyCORE-P8xC51Mx2, the
factory default configuration enables access to the Silicon Serial
Number using port pin P1.1 (GPIO1).
As an alternative (JP19 = 2+3), access to the DS2401 Silicon Serial
Number can be enabled via user code by means of data bit D1 at
address 00:FDA0h (IOSW = 0) or 3F:FDA0h (IOSW = 1).
