Intel Pentium P55CLM Microprocessor

The 166 MHz Intel Pentium microprocessor with MMX technology used in the NEC Versa
series computer is built on Intel's advanced 2.5V BiCMOS silicon technology. The CPU
has on-chip dual-processing, a local multiprocessor interrupt controller, and power man-
agement features. NEC adopted the chip specifically for its pipelined Floating Point Unit
(FPU), and local interrupt management.

M-Triton System Controllers

NEC implements Intel's Mobile Triton technology (MTDP 82430MX and MTSC
83437MX) for several of the notebook's subsystems including the DRAM controller, Sec-
ond Level Cache Controller and PCI Bus interface. The Mobile Triton PCI set features in-
clude:
T
3.3V EDO DIMM (70-ns) support
T
direct mapped organization write-back policy
T
fully synchronous 33 MHz PCI bus interface.
