Using the DS89C450 as a Static LCD Display Controller
Many Maxim microcontrollers integrate controllers for LCD displays, which are implemented in hardware. Some microcontrollers like the DS89C450 do not offer this functionality, but one can implement a simple display controller in software. This application note describes how to drive a static LCD panel with 7-segment digits using the DS89C450 ultra-high-speed flash microcontroller.
