PCF8576D

The PCF8576D is designed as one kind of universal LCD drive device that generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 160 segments. And PCF8576D is compatible with most microprocessors or microcontrollers PCF8576D and communicates via a two-line bidirectional I2C-bus. Communication overheads are minimized by a display RAM with auto-incremental addressing, by hardware subaddressing and by display memory switching (static and duplex drive modes). AEC-Q100 compliant for automotive applications.

Features of the PCF8576D are:(1)Low power consumption; (2)400 kHz I2C-bus interface; (3)May be cascaded for large LCD applications (up to 2560 elements possible); (4)No external components; (5)Compatible with chip-on-glass and chip-on-board technology; (6)Manufactured in silicon gate CMOS process; (7)40 x 4-bit RAM for display data storage; (8)Auto-incremented display data loading across device subaddress boundaries; (9)Display memory bank switching in static and duplex drive modes; (10)Versatile blinking modes; (11)Independent supplies possible for LCD and logic voltages; (12)Wide power supply range: from 1.8 V to 5.5 V.

The absolute maximum ratings of the PCF8576D can be summarized as:(1)supply voltage: -0.5 to +6.5 V;(2)supply current: -50 to +50 mA;(3)LCD supply voltage: -0.5 to +7.5 V;(4)LCD supply current: -50 to +50 mA;(5)input voltage: -0.5 to +6.5 V;(6)input current: -10 to +10 mA;(7)output voltage: -0.5 to +7.5 V;(8)output current: -10 to +10 mA;(9)latch-up current: 200 mA;(10)storage temperature: -65 to +150 °C;(11)operating temperature: -40 to +85 °C;(12)total power dissipation: 400 mW;(13)power dissipation per output: 100 mW.
