NXP PCF8577CT/3 芯片, 液晶屏驱动器, 32/64S段, 40VSOP
The is a LCD Direct/Duplex Driver with I²C-bus interface. The 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 sub addressing 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.
