PCF8577C
LCD direct/duplex driver with I²C-bus interface
Rev. 5 — 10 October 2014
Product data sheet
1. General description
The PCF8577C is an LCD driver which drives up to 32 segments directly, or 64 segments
in a duplex configuration.
The two-line I2C-bus interface substantially reduces wiring overheads in remote display
applications. I2C-bus traffic is minimized in multiple IC applications by automatic address
incrementing, hardware subaddressing and display memory switching (direct drive
mode).To allow partial VDD shutdown, the ESD protection system of the SCL and SDA
pins does not use a diode connected to VDD.
For a selection of NXP LCD segment drivers, see Table 13 on page 25.
