PCA85162

The PCA85162 is designed as one kind of LCD driver device that is compatible with most microprocessors or microcontrollers and communicates via a two-line bidirectional I2C-bus. Communication overheads of PCA85162 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 PCA85162 are:(1)Single-chip LCD controller and driver;(2)Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing;(3)Selectable frame frequency: 82 Hz or 110 Hz;(4)Internal LCD bias generation with voltage-follower buffers;(5)80 x 4 bit RAM for display data storage;(6)Auto-incremental display data loading across device subaddress boundaries;(7)Display memory bank switching in static and duplex drive modes;(8)Versatile blinking modes;(9)Wide power supply range: from 1.8 V to 5.5 V.etc.

The absolute maximum ratings of the PCA85162 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 +9.0 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 current: -10 to +10 mA;(8)ground supply current: -50 to +50 mA;(9)total power dissipation: 400 mW;(10)power dissipation per output: 100 mW;(11)latch-up current: 200 mA;(12)storage temperature: -55 to +150 °C;(13)operating temperature: -40 to +95 °C.
