PCF8578

LCD row/column driver for dot matrix graphic displays

Rev. 06 — 5 May 2009

Product data sheet

1. General description

The PCF8578 is a low power CMOS¹LCD row and column driver, designed to drive dot

matrix graphic displays at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has

40 outputs, of which 24 are programmable and conﬁgurable for the following ratios of

rows/columns: ³²⁄₈, ²⁴⁄₁₆, ¹⁶₂₄or ⁸⁄₃₂. The PCF8578 can function as a stand-alone LCD

⁄

controller and driver for use in small systems. For larger systems it can be used in

conjunction with up to 32 PCF8579s for which it has been optimized. Together these two

devices form a general purpose LCD dot matrix driver chip set, capable of driving displays

of up to 40960 dots. The PCF8578 is compatible with most microcontrollers and

communicates via a two-line bidirectional bus (I²C-bus). Communication overhead is

minimized by a display RAM with auto-incremented addressing and display bank

switching.

2. Features

I Single chip LCD controller and driver

I Stand-alone or may be used with up to 32 PCF8579s (40960 dots possible)

I Selectable multiplex rates: 1:8, 1:16, 1:24 or 1:32

I Externally selectable bias conﬁguration, 5 or 6 levels

I 1280-bit RAM for display data storage and scratch pad

I Display memory bank switching

⁄

₂₄or ⁸⁄₃₂

I Auto-incremented data loading across hardware subaddress boundaries (with

PCF8579)

I Provides display synchronization for PCF8579

I On-chip oscillator, requires only 1 external resistor

I Power-On Reset (POR) blanks display

I Logic voltage supply range 2.5 V to 6 V

I Maximum LCD supply voltage 9 V

I Low power consumption

I I²C-bus interface

I Compatible with most microcontrollers

I Optimized pinning for single plane wiring in multiple device applications (with

PCF8579)

I Space saving 56-lead small outline package and 64 pin quad ﬂat pack
