FAQ

1.Introduction of ST7567

ST7567 is a single-chip dot matrix LCD driver which incorporates LCD controller and common/segment drivers. ST7567 can be connected directly to a microprocessor with 8-bit parallel interface or 4-line serial interface (SPI-4). Display data sent from MPU is stored in the internal Display Data RAM (DDRAM) of 65x132 bits. The display data bits which are stored in DDRAM are directly related to the pixels of LCD panel. ST7567 contains 132 segment-outputs, 64 common-outputs and 1 icon-common-output. With built-in oscillation circuit and low power consumption power circuit, ST7567 generates LCD driving signal without external clock or power, so that it is possible to make a display system with the fewest components and minimal power consumption.
