DescriptionThe STE2004S is a low power CMOS LCD controller driver. Designed to drive a 65 rows by 102 columns graphic display, it provides all necessary functions in a single chip, including on-chip LCD supply and bias voltages generators, resulting in a minimum of externals components and in a very low power consumption.STE2004S features six standard interfaces (3-lines Serial, 3-lines SPI, 4-lines SPI, 68000 Parallel, 8080 parallel and I2C) for interfacing with the host micro-controller.COLUMNDRIVERSROWDRIVERSLATCHES65 x 102RAMDISPLAYCONTROLLOGICSCROLLLOGICDATAREGISTERINSTRUCTIONREGISTERCO to C101R0 to R64VSENSE SLAVERESVDD1,2CLOCKTIMINGGENERATORBIAS VOLTAGEGENERATORHIGH VOLTAGEGENERATORRESETTESTSHIFTREGISTER SS EXTVSSAUX to DB7D/CSA1SDOUTR/W- RD3 & 4 Line SPIParallel 8080Parallel 68KSEL 2OSCOSC_IN SLAVE SYNCwww.st.comContentsSTE2004S2/79 Contents1Block diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 42Pin description . . . . . . .
