supports 3 kinds of bus interface, namely 8 bit/ 4bit and serial. All functions, including display RAM, character
generator ROM, LCD display drivers and control circuits are all in a one-chip solution. With a minimum system
configuration, a Chinese character display system can easily achieved.
ST7920 includes character ROM with 8192 16X16 dots Chinese fonts and 126 16X8 dots half height alphanumerical
fonts. Also for graphic display it supports 64x256 dots graphic display area（GDRAM）and 240 dots ICON RAM. Mix
mode display with both character and graphic data is possible. ST7920 has built in 4 sets CGRAM providing
software programmable 16X16 font.
ST7920 has wide operating voltage (2.7V to 5.5V) and low power consumption suitable for battery power portable
device.
ST7920 LCD driver consists of 33 common and 64 segments. Together with extension segment driver ST7921,
ST7920 can support up to 33 common x 256 segments display.
