ENHANCEMENTS IN THE SME543XPCI CPU MODULE COMPARED WITH THE
SME5421MCZ VERSION
There are minor changes to the IIi CPU module for SME1430LGA (sapphire red).
Both the SME1430LGA and the SME1040CGA UltraSPARC-IIi processors are housed in the same LGA pack-
age. The SME1430LGA CPU used in this module contains functional improvements. This module also
employs a heatsink of revised design but the overall dimensions remain as before.
Electrical and Thermal Differences
Voltage Requirements
CPU core supply voltage VDD_CORE is reduced from 2.6 V to 1.9 V. This change is achieved by implementing
the appropriate resistor stufng conguration in the module to set the VID[4:0] bits on the system board. See
the table on page 17.
Power Consumption
Power consumption is reduced at a given frequency with an associated reduction in heat dissipation. See
Temperature and Cooling
The CPU runs at a reduced junction temperature Tj. See page 15. The module heatsink is changed to a
straight-n design. This requires airow in line with the n. See Figure 5.
Functional Differences
UPA Bus Frequency
The UPA bus is clocked at 1/4 the CPU core frequency
Memory Controller
A number of timing template bits in Mem_Control0 and Mem_Control1 registers have changed to support
higher internal clock rates with the same DIMM timing. For details, refer to the addendum to the UltraS-
PARC-IIi User’s Manual.
