1 / 8 page  TLF6146 April 1990 MM58201 Multiplexed LCD Driver General Description The MM58201 is a monolithic CMOS LCD driver capable of driving up to 8 backplanes and 24 segments A 192-bit RAM stores the data for the display Serial input and output pins are provided to interface with a controller An RC oscillator generates the timing necessary to refresh the display The magnitude of the driving waveforms can be adjusted with the VTC input to optimize display contrast Four additional bits of RAM allow the user to program the number of back- planes being driven and to designate the driver as either a master or slave for cascading purposes When two or more drivers are cascaded the master chip drives the backplane lines and the master and each slave chip drive 24 segment lines Synchronizing the cascaded drivers is accomplished by tying the RC OSC pins together and the BP1 pins togeth- er The MM58201 is packaged in a 40-lead dual-in-line pack- age or 44 lead plastic chip carrier package Features Y Drives up to 8 backplanes and 24 segment lines Y Stores data for display Y Cascadable Y Low power Y Fully static operation Applications Y Dot matrix LCD driver Y Multiplexed 7-segment LCD driver Y Serial inSerial out memory Block Diagram TLF6146 – 1 FIGURE 1 C1995 National Semiconductor Corporation RRD-B30M105Printed in U S A |
