ꢀ Description
The ST7036 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.
T
he ST7036 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, serial or fast I2C 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 display resolution of ST7036 dot-matrix LCD driver
can be either 1-line x 20 characters, 2-line x 20 characters
or 3-line x 16 characters with 80 bit ICON.
The ST7036 dot-matrix LCD driver does not need extra
cascaded drivers.
The ST7036 character generator ROM size is 256 5x8dot
bits which can be used to generate 256 different character
fonts (5x8dot).
