Microelectronics

The Delphi Reconfigurable Character Generator (RCG) is a custom IC which is capable of driving an LCD display at 1/14 duty, 1/5 bias, to a maximum of 10V. The IC contains 96 late-programmable ROM and 32 RAM alpha-graphic characters which can be selected for message display. The serial interface allows users to set contrast, read the temperature of the chip, control backlighting for the display, and define the message to display. The IC is designed to be wirebonded to a custom PCB and placed in a module containing the LCD glass and backlights.
