10.0 SECURITY REGISTER

The 24CS512 includes a 256-byte Security register,

organized as two 128-byte pages. The Security register

is segmented into a 128-byte read-only section and a

128-byte user-programmable lockable identification

page section. Device and word address requirements

to access the Security register are outlined in

Section 3.3.1 “Valid Device Address Byte Inputs”

and Section 3.3.2 “Word Address Bytes”.

The user-programmable portion supports both byte

write and page write operations. The read-only section

contains a preprogrammed, ensured unique, 128-bit

serial number. The user-programmable portion may be

permanently locked with the lock operation.

Note:

The entire 128-bit serial number must be

used to ensure a unique number.
