Introduction The RA0086 is an 80 channels LCD driver LSI which is fabricated by low power CMOS high voltage process technology. It can be used either as a COMMON driver or as a SEGMENT driver, by connecting its CS input to VDD or VSS. In segment driver mode, it can be interfaced in 1-bit serial or 4-bit parallel method by the controller. In common driver mode, dual type mode is applicable. And in segment mode application, the power down function reduces power consumption. 2.

Signal Description 4-1 Block Description Name Clock control Function COM / SEG Generates latch clock (LCK), shift clock (SCK) and control clock timing according to the input of CL1, CL2 and control inputs (CS, AMS). In COM / SEG common driver application mode, this block generates the shift clock (LCK) for the common data Bi-directional shift register. Data latch control Determines the direction of segment data shift, and input data of each Bi-directional shift register. In 4-bit segment data parallel transfer mode, data is shifted by a 4-bit unit. In common driver application mode, data is transferred to the common data shift register directly, which disables this block. SEG Power down function Controls the clock enable state of the current driver according to the input value of enable pin (ELB or ERB). If enable input value is “Low”, every clock of the current driver is enabled and the clock control block works. But if enable input is “High”, current driver is disabled and the input data value has no effect on the output level. So power consumption can be lowered. SEG Output level selector Controls the output voltage level according to the input control pin (M COM / SEG and DISPOFFB) (refer to Section 4-2). 20x4-bit segment data BI-directional shift register Stores output data value by shifting the input values. In 1-bit serial interface mode application, all 80 shift clocks (SCK) are needed to store all the display data. But in 4-bit parallel transfer mode application, only 20 clocks are needed. In common driver application mode, this block does not work. 80-bit data latch / common data BI-directional shift register In segment driver application mode, the data from the 20x4-bit segment data shift register are latched for segment driver output. In single-type common driver application,1-bit input data (from DL or DR pin) is shifted COM / SEG and latched by the direction according to the SHL signal input. In dualtype common application mode, 80-bit registers are divided by two blocks and controlled independently (refer to Section 4-2-3). SEG 80-bit level shifter Voltage level shifter block for high voltage part. The inputs of this block are of logical voltage level and the outputs of this block are at high voltage level value. These values are input in to the driver. SEG 80-bit 4-level driver Selects the output voltage level according to M and latched data value. If the data value is "High" the driver output is at selected voltage level (V0 or V5), and in the reverse case the driver output value is at the nonselected level (V12 or V43). In segment driver application mode, nonselected output value is V2 or V3. and when in common driver application, this value becomes V1 or V4.
