Product Description
1.1 C0B process, product with backlight, conductive tape connection, stable structure,
1.2 IC uses st7920, two chip options for simplified Chinese character library or traditional Chinese character library.
1.3 Low power consumption, with 5V/3.3V two power modes, no backlight current within 8mA, backlight current within 100mA.
1.4 LED can be driven by PIN1, PIN2, PIN19, PIN20.
1.5 Product features:
Built-in character library ROM (CGROM): a total of 8192 characters
Built-in half-width character ROM (HCGROM): a total of 126 alphabetic characters
Built-in drawing RAM (GDRAM): 64x256bit
Display 8 characters x 4 lines (16x16 dot matrix).
