MSM5299C
MSM5299C is 80-DOT LCD SEGMENT DRIVER manufactured by OKI Electric.
DESCRIPTION
The MSM5299C is a dot matrix LCD segment driver LSI which is fabricated using CMOS low power metal gate technology. This LSI consists of an 80-bit bidirectional shift register, 80-bit latch, 80-bit level shifter, and 80-bit 4-level driver. It receives the 4-bit parallel display data transferred from a microputer or an LCD controller LSI such as MSM6255, then outputs the LCD driving waveform to the LCD. This LSI is improved with respect to timing between load and clock in the switching characteristics of MSM5299A. (t LC = 200ns Æ 63ns) However, note that the timing regulations for the load signal leading edge are added.
