GENERAL DESCRIPTION
ST7565P is a single-chip dot-matrix LCD driver that can be
connected directly to a microprocessor bus. 8-bit parallel or
serial display data sent from the microprocessor is stored in
the internal Display Data RAM and this chip generates LCD
driving signals independent of the microprocessor. Each
data bits (65x132) of the internal Display Data RAM is 1-to-1
correspondence with each pixels (65x132) on the LCD
panel, therefore, ST7565P enables displays with a high
degree of freedom.
Moreover, the display area can be extended horizontally by
using Master/Slave feature.
With the abundant embedded circuits (2~6 times booster
circuit, V0 regulator with contrast control for LCD voltage
adjustment, voltage follower with bias selection and R-C
oscillation circuit), ST7565P can be used to create a display
system with the lowest power consumption and the fewest
external components for high-performance portable devices.
