PCF8532

The PCF8532 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 PCF8532 is compatible with most microprocessors or microcontrollers of PCF8532 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).

Features of the PCF8532 are:(1)Two sets of backplane outputs for optimal COG configurations of the application;(2)Manufactured in silicon gate CMOS process;(3)No external components;(4)Display memory bank switching in static and duplex drive modes;(5)Compatible with Chip-On-Glass (COG) technology; (6)Versatile blinking modes;(7)Auto-incremental display data loading across device subaddress boundaries;(8)Low power consumption, typically: IDD = 4 uA, IDD(LCD) = 40 uA;(9)Wide power supply range: from 1.8 V to 5.5 V;(10)LCD and logic supplies may be separated.

The absolute maximum ratings of the PCF8532 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.
