n Description
The ST7032 dot-matrix liquid crystal display controller can
display alphanumeric, Japanese kana characters, and
symbols. It can be configured to drive a dot-matrix liquid
crystal display under the control of a 4 / 8-bit with
6800-series or 8080-series, 3/4-line serial interface
microprocessor. Since all the functions such as display
RAM, character generator ROM/RAM and liquid crystal
driver, required for driving a dot-matrix liquid crystal display
are internally provided on one chip, a minimal system can
be used with this controller/driver.
The ST7032 character generator ROM size is 256 5x8dot
bits which can be used to generate 256 different character
fonts (5x8dot).
The ST7032 is suitable for low voltage supply (2.7V to
5.5V) and is perfectly suitable for any portable product
which is driven by the battery and requires low power
consumption.
The ST7032 LCD driver consists of 17 common signal
drivers and 80 segment signal drivers. The maximum
display RAM size can be either 80 characters in 1-line
display or 40 characters in 2-line display. A single ST7032
can display up to one 16-character line or two 16-character
lines.
The ST7032 dot-matrix LCD driver does not need extra
cascaded drivers.
