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.
2. Features and benefits
Direct/duplex drive modes with up to 32/64 LCD-segment drive capability per device Operating supply voltage: 2.5 V to 6 V Low power consumption I2C-bus interface Optimized pinning for single plane wiring Single-pin built-in oscillator Auto-increm...
