All inputs are CMOS compatible. All necessary functions for the display are provided in a single chip, including on-chip generation of VLCD and the LCD bias voltages. This results in a minimum requirement of external components and low power consumption. DESCRIPTION The IC is a low-power CMOS LCD controller/driver, designed to drive grey - scale or ECB color dot matrix graphic displays at multiplex rates of 1:33 or 1:67. PINNING Name R0 ...
