説明

VB1-

PWR

LCD Bias Voltages. These are the voltage source to provide SEG driving currents. These voltages are generated internally. Connect capacitors of CBX between VBX+ and VBX–.
The resistance of these four traces directly affects the SEG driving strength of the resulting LCD module. Minimize the trace resistance is critical in achieving high quality image.

VB1+

VB0-

VB0+

VLCD

PWR

Main LCD Power Supply. Connect these pins together.

VBIAS

This is the reference voltage to generate the actual SEG driving voltage. VBIAS can be used to fine tune VLCD by external variable resistors. Internal resistor network has been provided to simplify external trimming circuit.
In COF application, connect a small bypass capacitor between VBIAS and VSS to reduce noise.

VSS

PWR

Ground

VDD

PWR

Supply Voltage for logic

I/O

Bi-directional bus for both serial and parallel host interfaces.
In serial modes, connect D[0] to SCK, D[3] to SDA,

	BM=1x (Parallel)	BM=0x (Parallel)	BM=01 (S9)	BM=00 (S8/S8uc)
D0	D0	D0/D4	SCK	SCK
D1	D1	D1/D5	-	-
D2	D2	D2/D6	-	-
D3	D3	D3/D7	SDA	SDA
D4	D4	-	-	-
D5	D5	-	-	-
D6	D6	-	S9	S8/S8uc
D7	D7	0	1	1

Connect unused pins to VDD or VSS.

WR1

WR[1:0] controls the read/write operation of the host interface. See Host Interface section for more detail.
In parallel mode, WR[1:0] meaning depends on whether the interface is in the 6800 mode or the 8080 mode. In serial interface modes, these two pins are not used, connect them to VSS.

WR0

Select Control data or Display data for read/write operation. In S9 mode, CD pin is not used. Connect CD to VSS when not used. ”L”: Control data ”H”: Display data

RST

When RST=”L”, all control registers are re-initialized by their default states.
Since UC1608x has built-in Power-ON-Reset and Software Reset command, RST pin is not required for proper chip operation. When RST is not used, connect the pin to VDD.

Chip Select. The chip is selected when CS=”H”. When the chip is not selected, D[7:0] will be high impedance.

BM0

Bus mode: The interface bus mode is determined by BM[1:0] and D[7:6] by the following relationship:

BM[1:0]	D[7:6]	Mode
11	Data	6800/8-bit
10	Data	8080/8-bit
1	0X	6800/8-bit
0	0X	8080/8-bit
1	10	3-wire SPI w/9-bit token (S9: conventionl)
0	10	4-wire SPI w/8-bit token (S8: conventionl)
0	11	3- or 4-wire SPI w/8-bit token (S8uc: Ultra-Compact)
