AYRINTILAR

Arayüz Pin Fonksiyonlari

Pin No. Symbol TANIM
1 ESD GND Electro-Static discharge
2 VG VG is the power of SEG-drivers
3 XV0 Negative operating voltage of COM-drivers
4 V0 Positive operating voltage of COM-drivers
5 VM VM is the non-select voltage level of COM-drivers.
6 VDDA Power supply
7 VSS Ground
8 VD1 Digital power source selection.
9 VDDI VDD1 is the power of interface I/O circuit
10 CSB Chip select input pin
CSB=“L”: This chip is selected and the MPU interface is active
CSB=“H”: This chip is not selected and the MPU interface is disabled
(D[7:0] are high impedance)
11 IF3 These pins select interface operation mode.
IF3 IF2 IF1 MPU interface type
H H L 80 series 8-bit parallel
H L L 68 series 8-bit parallel
L H H 8-bit serial (4-Line)
L H L 9-bit serial (3-Line)
12 IF2
13 IF1
14 RSTB Reset input pin. When RSTB is “L”, internal initialization procedure is executed.
15 /RD(E) Read / Write execution control pin. (This pin is only used in parallel interface)
MPU Type ERD Descriptin
6800-series ERD Read/Write control input pin
R/W = "H" When E is "H", data bus is in output status.
R/W = "L" The data are lunched at the failling edge of the E signal.
8080-series /RD Read enable inputpin.
When /RD is "L". Data bus is in output status.
16~23 D7~D0 The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance.
If using serial interface:
D0 is the SDA signal in 4-Line & 3-Line interface.
D1 is the A0 signal in 4-Line interface
24 /WR/(R/W) Read / Write execution control pin. (This pin is only used in parallel interface
MPU Type RWR Descriptin
6800-series R/W Read/Write control input pin
R/W = "H" : Read
R/W = "L" : write
8080-series /WR Write enable clock input pin.
The data are layched at the rising edge of the /WR signal.
This pin is not used in serial interfaces and should be connected to VDD1
25 A0(SCL) The function of this pin is different in parallel and serial interface
In parallel interface: A0 is register selection input
A0 = "H": inputs on data bus are display data
A0 = "L": inputs on data bus are command
In serial interface: this pad will be used as SCL (serial-clock) input
26 ESD GND Electro-Static discharge
