Notes
1. In a registered DIMM, data is delayed an additional clock cycle due to the on-DIMM pipeline register (i.e., Device CL [clock cycles]
+ 1 = DIMM CAS latency).
2. Minimum application clock cycle time for the -360, -365, -370 is 10ns (100MHz), and for -10 is 15ns (66MHz).
3. cc = Checksum Data byte, 00-FF (Hex)
4. “R” = Alphanumeric revision code, A-Z, 0-9
5. rr = ASCII coded revision code byte “R”
6. ww = Binary coded decimal week code, 01-52 (Decimal)
01-34 (Hex)
7. yy = Binary coded decimal year code, 00-99 (Decimal)
00-63 (Hex)
8. ss = Serial number data byte, 00-FF (Hex)
9. This table displays an example of the Assembly Part Numbers available.
