PCE85176AUG
description
The PCE85176AUG 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. The PCE85176AUG 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 and by display memory switching (static and duplex drive modes).
For a selection of NXP LCD segment drivers, see Table 31 on page 40.
