Description
5.5V) of the ST7036 is suitable for any portable
The ST7036 dot-matrix liquid crystal display controller and
driver LSI displays 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, serial or fast I2C interface microprocessor. Since all
the functions such as display RAM, character generator,
and liquid crystal driver, required for driving a dot-matrix
liquid crystal display are internally provided on one chip, a
minimal system can be interfaced with this
battery-driven product requiring low power dissipation.
The ST7036 LCD driver consists of 17 common signal
drivers and 100 segment signal drivers. And the second
mode is consists of 25 common signal 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 or 16 characters in 3-line. A single ST7036
can display up to one 20-character line or two 20-character
lines or three 16-character lines.
controller/driver.
No extra drivers can be cascaded.
The ST7036 character generator ROM is extended to
generate 256 5x8dot character fonts for a total of 256
different character fonts. The low power supply (2.7V to
