GeneralDescription
HT1622isaperipheraldevicespeciallydesignedforI/O
type MCU used to expand the display capability. The
max. display segment of the device are 256 patterns
(32′8). It also supports serial interface, buzzer sound,
Watchdog Timer or time base timer functions. The
HT1622 is a memory mapping and multi-function LCD controller. The software configuration feature of the HT1622makeitsuitableformultipleLCDapplicationsin- cluding LCD modules and display subsystems. Only threelinesarerequiredfortheinterfacebetweenthehost controller and the HT1622. The HT162X series have manykindsofproductsthatmatchvariousapplications. SelectionTable
