This pin is the segment output current reference pin.
A resistor should be connected between this pin and V
around 10uA. Please refer to section 8.6 for the formula of resistor value from I
This pin must be connected to V
External clock input pin.
When internal clock is enable (i.e. pull HIGH in CLS pin), this pin is not used and
should be connected to Ground.
When internal clock is disable (i.e. pull LOW is CLS pin), this pin is the external
clock source input pin.
Internal clock selection pin.
When this pin is pulled HIGH, internal oscillator is enabled (normal operation).
When this pin is pulled LOW, an external clock signal should be connected to CL.
This pin is the chip select input connecting to the MCU. The chip is enabled for MCU
communication only when CS# is pulled LOW.
This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin pull HIGH during normal operation.
This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the content at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the content at D[7:0] will be interpreted as command.
This pin is read / write control input pin connecting to the MCU interface.
When interfacing to a 6800-series microprocessor, this pin will be used as
Read/Write (R/W#) selection input. Read mode will be carried out when this pin is
pulled HIGH and write mode when LOW.
When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data
write operation is initiated when this pin is pulled LOW and the chip is selected.
When serial interface is selected, this pin R/W (WR#) must be connected to V
This pin is MCU interface input.
When interfacing to a 6800-series microprocessor, this pin will be used as the Enable
(E) signal. Read/write operation is initiated when this pin is pulled HIGH and the
chip is selected.
When connecting to an 8080-microprocessor, this pin receives the Read (RD#)
signal. Read operation is initiated when this pin is pulled LOW and the chip is
selected.
When serial interface is selected, this pin E(RD#) must be connected to V
These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW. (Except for D2 pin in SPI mode)
Refer to Section 8.1 for different bus interface connection.
These are reserved pins and should be connected to V
