PCA85162 Datasheet | NXP Semiconductors

description The PCA85162 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 32 segments. It can be easily cascaded for larger LCD applications. The PCA85162 is patible with most microcontrollers and municates via the two-line bidirectional I2C-bus. munication 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 25 on page 48. 2.
