Notes
1. In a registered DIMM, data is delayed an additional clock cycle due to the on-DIMM pipeline register (that is, Device CL [clock
cycles] + 1 = DIMM CAS latency).
2. Minimum application clock cycle time is 7.5ns (133MHz).
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, 01-51 (Decimal) ‘ 01-34 (Hex).
7. yy = Binary coded decimal year code, 0-00 (Decimal) ‘ 00-63 (Hex).
8. ss = Serial number data Byte, 00-FF (Hex).
9. These values apply to PC100 applications only.
