#ComponentsCloseUp No. 170: VIPER MIOC
-
** Quick Facts! **
Manufacturer: HP
Part Number: 1FZ6-0006
Chip Name: Viper
Die Size: 9,5×9,5 mm2
Process Node: 0.80µm
Transistor Count: 185,000
Package Type: 272-pin CPGA
-
This chip, often just referred to as the Viper, was the MIOC (Memory and Input Output Controller) for the PA-7100 and PA-7000 processors (RISC). The Viper chip is responsible for all memory and I/O transactions between the processor and the rest of the system. The website www.openpa.net/ has a lot of great information about this chip.
-
As noted above, there is a beautiful silicon doodle on this chip of a Viper (in some pretty great detail). There is also a block of initials of the engineers and other people that helped out with the design. One thing that I missed initially that was pointed out to me by @siliconinsider was some very discrete text hidden on the chip. Can you make out what it says?😉

I wonder who was the person to write the little text there to tell us we're too close

I wonder if the designers ever imagined that these texts would be actually filmed

Please give us a chip photo of a "Write Only Memory" (WOM). They actually got made in the 1960s but were a prank. 😂

I'd watch an hour-long deep dive into your chip of choice, where we go through each channel and how they interact with one another.
