O
Column/Row output
CP
24
I
Data shift clock.
The data is shifted to 80 bits shift register at the falling edge of ‘CP’ when used as column
driver.
LD
23
I
Data load pulse.
When used as a column driver, a row of display data is latched at the falling edge of ‘LD’.
When used as a row driver, ‘LD’ is the shift clock input.
DIO1C
DIO2C
DIO1R
DIO2R

I/O
Series data input/output of column/row driver.
1). When ‘L/R’ = 1, ‘DIO1C’ and ‘DIO1R’ are series data inputs of column driver and row driver
respectively. ‘DIO2C’ and ‘DIO2R’ are series data outputs of column driver and row driver
respectively.
2). When ‘L/R’ = 0, ‘DIO2C’ and ‘DIO2R’ are series data inputs of column driver and row driver
respectively. ‘DIO1C’ and ‘DIO1R’ are series data outputs of column driver and row driver
respectively.
3). When ‘MODE1’
⊕
’Mode2’ = 0, ‘COL/ROW’ = 1, SPOD80A is used as dedicated column
driver, series data input of row driver, ‘DIO1R’ or ‘DIO2R’ depending on ‘L/R’, should be
connected to VSS or float.
4). When ‘MODE1’
⊕
’Mode2’ = 0, ‘COL/ROW’ = 0, SPOD80A is used as dedicated row driver,
series data input of column driver, ‘DIO1C’ or ‘DIO2C’ depending on ‘L/R’, should be
connected to VSS or float.

Selection of data shift direction
MODE1
MODE2
53
52
I
Mode selection. There are 12 modes can be selected when combine ‘MODE1’, ‘MODE2’ with
‘COL/ROW’ and ‘L/R’.
CV
22
I
Selection of driving method, default is ‘H’.
CV = 1, current driving mode
CV = 0, voltage driving mode
This mode selection is valid when used as column driver only.
BTV

I
I
Brightness control input. By adjusting an external voltage (VBT) and resistor (RBT), the output
current in O[1:80] can be adjusted, see function description. This adjustment is valid when
used as column driver and CV = 1 only.
RB1

-
Internal/external resistor selection.
Connect this pin to ground while using internal resistor, or float it when using external resistor
