The NXP Semiconductors PCF8578T is a versatile, low-power CMOS LCD driver capable of controlling dot matrix graphic displays. It supports multiplex rates from 1:8 to 1:32 and offers 40 configurable driver outputs, with 24 programmable for various row/column ratios like 32/8, 24/16, 16/24, or 8/32.
This device features a 1280-bit display RAM for data storage and supports display bank switching. Communication is handled via a standard I2C-bus interface, making it compatible with most microcontrollers. The PCF8578T can operate as a stand-alone controller or be used in conjunction with up to 32 PCF8579 devices for larger display systems, potentially driving up to 40960 dots.
It operates with a logic supply voltage range of 2.5 V to 6 V and a maximum LCD supply voltage of 9 V. The device includes an on-chip oscillator and a Power-On Reset function. The PCF8578T is available in space-saving packages, including a 56-lead small outline package (VSO56).
Applications for the PCF8578T include automotive information systems, telecommunication systems, point-of-sale terminals, industrial computer terminals, and instrumentation where efficient and reliable LCD control is required.
