							1.2 Product Overview
The TravelMate 5000 Series Notebook Computers are high performance,
multimedia notebooks powered by the Intel P54-C Pentium tm superscalar
processor with built-in co-processor and dual, on-chip, 16KB data and
instruction caches. The 3-volt, Pentium chip, packaged in the TAB TCP
format, generates a 75 MHz clock processing rate. An off-chip, 256KB L2
cache buffer using asynchronous, 15 ns SRAM, is also implemented to
support the power of the Pentium. A simplified block diagram of the TM5000
Pentium Notebook is provided in Figure 1-2.
