Product Summary

The RG82845MP is a chipset. The RG82845MP supports the Mobile Intel Pentium 4 Processor-M at 100MHz bus frequency; the address signals run at 200 MT/s for a maximum address queue rate of 50M addresses/sec. The data is quad pumped and an entire 64B cache line can be transferred in two bus clocks. At 100-MHz bus frequency, the data signals run at 400 MT/s for a maximum bandwidth of 3.2GB/s. A 12-deep IOQ is supported by the 845MP/845MZ Chipset.
