SL70D0948

FUNCTION DESCRIPTION

SYSTEM INTERFACE

Chip Enable Input

The chip enable pins are /CE1 and CE2. The SL70D0948 can enable chip by /CE1=0, and CE2=1.

If the SL70D0948 is enable then it can receive signal that DIN,SHCLK and STROBE.

Output Enable Input

The SL70D0948 has output enable pin (OEB). If the OEB = 1, all output are off and if OEB = 0 then

all output pins are PWM output.

Data Input / Output

The SL70D0948 has 9bit data input pins (DIN[8:0]) and 9bit data output pins (DOUT[8:0]).

The output data is out after 48 times

SHCLK from input data. If DOUT[8:0] pins are connected

to next device DIN[8:0] pins, the first device 48bit input data can shift the next device 48bit input

data by SHCLK. It can transfer display data to serial method so it makes device to connect directly.

The 9bit LED input data are MSB first inputted. The 9bit input data are inputted 9bit LED1 and next

9bit LED2 and next

9bit LED3 …
