Product Summary
The SED1560TOB is an intelligent CMOS LCD drivercontroller with the ability to drive alphanumeric and graphic displays. The SED1560TOB communicates with a high-speed microprocessor, such as the Intel 80XX family or the Motorola 68XX family, through either a serial or an 8-bit parallel interface. It stores the data sent from the microprocessor in the built-in display data RAM (166 × 65 bits) and generates an LCD drive signal. The SED1560TOB incorporates an internal DC/DC converter to generate the negative voltage needed for LCD contrast. The controllers feature software contrast adjustment by command setting.
