Designed to drive a 81 rows by 128 columns graphic display, provides all necessary functions in a single chip, including onchip LCD supply and bias voltages generators, resulting in a minimum of externals ponents and in a very low power consumption. The STE2002 features three standard interfaces (Serial, Parallel & I2C) for ease of interfacing with the host microcontroller. - - - Block diagram CO to C127 R0 to R80 ICON OSC_IN OSC_OUT TIMING GENERATOR CLOCK COLUMN DRIVERS ROW DRIVERS VLCDIN BIAS VOLTAGE GENERATOR DATA LATCHES SHIFT REGISTER VLCDSENSE VLCDOUT HIGH VOLTAGE GENERATOR RES VSSAUX VDD1,2 VSS SEL1,2 RESET 104 x 128 RAM SCROLL LOGIC TEST_1_14 TEST DATA REGISTER INSTRUCTION REGISTER DISPLAY CONTROL LOGIC ICON_MODE EXT...
