Introduction

The Printer’s engine electronics (Main PCA) is controlled by a Kayak ASIC. Kayak is the application-specific integrated circuit (ASIC), designed in Hewlett-Packard’s Vancouver Printer Division, forming the heart of the thermal-inkjet large format printer digital electronics.

Hardware Description

„The Kayak ASIC is fed with a 15.975MHz crystal-quartz which through a phase lock loop (PLL) is raised to 192MHz and after that divided to the ColdFire frequency of 96MHz and further divided to the external memory bus of 48MHz.

„The Kayak ASIC incorporates the CF3_g Motorola CF3MRSX processor mega cell. As implemented in Kayak, the processor, with 8KB of unified cache, has a maximum operating frequency of 98MHz and at this frequency it is capable of approx. 70 MIPS.

„Two physical EIO slots are supported from which the optional formatters and EIO cards will be plugged. Three expansion options are currently supported.

„The Main PCA will come with an on-board 4MB flash memory that will allow both the end user and service engineers to upgrade with the latest firmware code available.

„A total of 16MB SDRAM (x32) or 32MB SDRAM (depending on the Printer Model) will be loaded in the engine PCA, not allowing further user self-memory upgrades.
