Description
The STE2007 is a low power LCD driver, capable
to drive 96 columns and up to 68 lines, designed
for monochrome displays.
The STE2007 includes fully integrated bias
voltage generator (up to 5x multiplication factor),
and internal oscillator, thus reducing to minimum
the number of external components required and
the current consumption.
The STE2007 features the three standard serial
interfaces (3 and 4 lines serial, I2C interface).
