3. FEATURE DESCRIPTION
The VIPer 821 is built around the Pentium and Pentium MMX processors from Intel.
K6 and K6-2 processors from AMD are also supported:
Processors Internal Clock Speed
Pentium 75, 90, 100, 120, 133, 150, 166 and 200 MHz
Pentium MMX 166, 200 and 233 MHz
AMD K6
166, 200 and 233 MHz
AMD K6-2 233, 266, 300, 333 and 366MHz
The power supply of the CPU is provided by the TEK-067 DC/DC Converter module.
When installing a new processor, jumper settings must be provided on both the DC/DC
Converter module (for the CPU voltage), and the VIPer 821 board (for the Clock Speed).
To avoid damage to the processor, the CPU voltage must be as specified by the CPU
manufacturer:
Single-voltage Pentium processors must be set for 3.3 V only. In the case of split-core
technology (Pentium MMX or K6), the right core voltage must be selected. For example,
Pentium MMX processors running at 166MHz, 200MHz and 233MHz require 2.8 V core
voltage. Be sure you know the specified core voltage for your processor when it is a split-
core technology!
