PT6553

DESCRIPTION

PT6553 is an LCD Driver IC providing key scan circuitry which can accept up to a maximum of 30 keys,

thereby, reducing printed circuit board wiring. It can drive up to 126 segments and is capable of

controlling up to 4 general purpose output ports. The reset circuit provides on-chip voltage detection

making it possible to prevent incorrect displays. Pin assignments and application circuit are optimized

for easy PCB layout and cost saving advantages.
