The PCF8579HT/1 from NXP Semiconductors is a low-power CMOS LCD column driver optimized for driving dot matrix graphic displays. It supports selectable multiplex rates of 1:8, 1:16, 1:24, or 1:32 and features 40 column outputs. This device is designed to work in conjunction with the PCF8578 LCD row/column driver to form a chip set capable of driving displays up to 40960 dots.
Key electrical specifications include a logic voltage supply range of 2.5V to 6V and a maximum LCD supply voltage of 9V. It communicates via a two-line bidirectional I2C-bus interface, making it compatible with most microcontrollers. The device has a low power consumption and operates within an ambient temperature range of -40°C to 85°C.
The PCF8579HT/1 is available in a 64-lead TQFP package, suitable for surface mount applications. It includes 1280 bits of RAM for display data storage and supports display memory bank switching. The device is also easily cascadable for larger applications, supporting up to 32 devices on the same I2C-bus.
