8 / 49 page  ST7567 Ver 1.4b 8/49 2009/02/04 5. PIN DESCRIPTION LCD Driver Output Pins Pin Name Type Description No. of Pins SEG0 to SEG131 O LCD segment driver outputs. The display data and the frame control the output voltage. Segment Driver Output Voltage Display data Frame Normal Display Inverse Display H + VG VSS H - VSS VG L + VSS VG L - VG VSS Display OFF, Power Save VSS VSS 132 COM0 to COM63 O LCD common driver outputs. The internal scanning signal and the frame control the output voltage. Common Driver Output Voltage Scan signal Frame Normal Display Inverse Display H + XV0 H - V0 L + VM L - VM Display OFF, Power Save VSS 64 COMS1, COMS2 (COMS) O LCD common driver outputs for icons. The output signals of these two pins are the same. When icon feature is not used, these pins should be left open. 2 Microprocessor Interface Pins Pin Name Type Description No. of Pins RSTB I Hardware reset input pin. When RSTB is “L”, internal initialization is executed and the internal registers will be initialized. 1 CSB I Chip select input pin. Interface access is enabled when CSB is “L”. When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance. 1 A0 I It determines whether the access is related to data or command. A0=“H” : Indicates that signals on D[7:0] are display data. A0=“L” : Indicates that signals on D[7:0] are command. 1 RWR I Read/Write execution control pin. When PSB is “H”, C86 MPU Type RWR Description H 6800 series R/W Read/Write control input pin. R/W=“H”: read. R/W=“L”: write. L 8080 series /WR Write enable input pin. Signals on D[7:0] will be latched at the rising edge of /WR signal. RWR is not used in serial interface and should fix to “H” by VDD1 or VDDH. 1 |
