Character Sets
EM6121 is controller and driver for character monochrome
for TN and STN LCD displays. The driving capability is
26 rows x 80 columns (3x16, 2x24 or 1x48 rows of
16 characters + 160 icons) addressed by I2C or 3-wire
interface. The chip includes a character generator CGROM
of 240 characters and CGRAM of 16 characters. VLCD
internally generated up to 9.35V without external
components or with external capacitors.
