The EEPROM stores engine calibration and printer configuration settings.

T6090 Personality Module

Interface control is provided by the Personality Module.   There are four Personality Modules

available, two of which have optional configurations.  The configurations vary in terms of host

interface, memory configuration, and installed software.

The primary components of the Personality Module are:

•

Main processor – Motorola MC68340

•

Flash EPROM – comprised of 4M-bit and/or 2M-bit parts (determined by the type of

interface)

•

DRAM –  .5 Meg, 1 Meg, or 2 Meg (determined by the type of interface)

•

EPLD – Altera EPM7064

•

Parts specific to the type of interface (Serial/Parallel, Lan, Twinax/Coax and

Dataproducts).  (See Table 1-1.)

 The following table shows the modules and optional configurations:
