4.01.1 MICROPROCESSOR
The VIPer808 supports the following microprocessors (maximum internal CPU clock
speed and CPU voltage are indicated):
•
AMD 486DX2SV running at 66 MHz (3.3V);
•
AMD 486DX4SV running at 100 MHz (3.3V);
•
AMD 5x86 running at 133 MHz (3.3V) .
This processor is also referred to a 486DX5;
•
Intel 486DX running at 33 MHz (5V);
•
Intel 486DX2 running at 66 MHz (5V);
•
Intel 486DX4 running at 100 MHz (3.3V);
•
SGS 486DX2V running at 66 MHz (3.3V);
•
SGS 486DX4V running at 100 MHz (3.3V).
The Math Co-processor is internal to the CPU (Central Processing Unit).
The above processors also have Internal Cache Memory available.
The following jumpers are related to the CPU:
•
W1: Selects the voltage for powering CPU:
- Shorted:
5V,
- Or open: 3.3V.
WARNING: Incorrect CPU voltage can damage your CPU!
•
W18: Selects the desired external CPU bus speed:
- W18 pins 3 and 4 shorted:
25MHz,
- Or W18 pins 1 and 2 shorted: 33MHz.
•
W15A, W15B and W15C: These jumpers are used in conjunction with W15 to select
CPU Type. See Jumper Settings tables in Section 3 for supported types and their
settings.
