It supports 3 kinds of bus interface, namely 8-bit, 4-bit and serial. All functions, including display RAM, Character Generation 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 be easily achieved. ST7920 includes character ROM with 8192 16x16 dots Chinese fonts and 126 16x8 dots half-width alphanumerical fonts. Besides, it supports 64x256 dots graphic display area for graphic display (GDRAM). Mix-mode display with both character and graphic data is possible. ST7920 has built-in CGRAM and provide 4 sets software programmable 16x16 fonts. ST7920 has wide operating voltage range (2.7V to 5.5V). It also has low power consumption. So ST7920 is suitable for battery-powered portable device. ST7920 LCD driver consists of 32-common and 64-segment. Company with the extension segment driver (ST7921) ST7920 can support up to 32-common x 256-segment display. Part Number Font Code ST7920-0A BIG-5 Code Set (Traditional Chinese) ST7920-0B GB Code Set (Simplified Chinese) ST7920-0C Chinese (Traditional/Simplified) & Japanese ST7920-0F Chinese (Traditional/Simplified), Japanese & Korean |
