General description

The PCA8576F is a peripheral device which interfaces to almost any Liquid Crystal

Display (LCD)1 with low multiplex rates. It generates the drive signals for any static or

multiplexed LCD containing up to four backplanes and up to 40 segments. It can be easily

cascaded for larger LCD applications. The PCA8576F is compatible with most

microcontrollers and communicates via the two-line bidirectional I2C-bus. Communication

overheads are minimized by a display RAM with auto-incremented addressing, by

hardware subaddressing and by display memory switching (static and duplex drive

modes).

For a selection of NXP LCD segment drivers, see Table 28 on page 46.
