HD66100F Datasheet, PDF (5/17 Pages) Hitachi Semiconductor – LCD Driver with 80-Channel Outputs

HD66100F
Pin Description
V_CC, GND, V_EE: V_CC supplies power to the internal logic circuit. GND is the logic and drive ground. V_EE
supplies power to the LCD drive circuit.
V1, V2, V3, and V4: V1 to V4 supply power for driving an LCD (Figure 2).
CL1: HD66100F latches data at the negative edge of CL1.
CL2: HD66100F receives shift data at the negative edge of CL2.
M: Changes LCD drive outputs to AC.
DI: Inputs data to the shift register.
DO: Output data from the shift register.
SHL: Selects a shift direction of serial data. When the serial data is input in order of D1, D2, ..., D79,
D80, the relation between the data and the output Y is shown in Table 3.
Y1–Y80: Each Y outputs one of the four voltage levels—V1, V2, V3, or V4—according to the
combination of M and display data (Figure 2).
NC: Do not connect any wire to these terminals.
