PCF8576D 40 × 4 universal LCD driver for low multiplex rates Rev. 15 — 12 February 2015 Product data sheet 1. General description The PCF8576D 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 PCF8576D 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). • PCF8576DT/2 should not be used for new design-ins. Replacement part is PCF85176T/1 for industrial applications • PCF8576DT/S400/2 should not be used for new design-ins. Replacement part is PCA85176T/Q900/1 for automotive applications For a selection of NXP LCD segment drivers, see Table 30 on page 50. 2. Features and benefits              1.
