Getting Started Guide
Bring up the Flexible OLED CFAL16032A0-018P-W
using the Generic Adapter Board CFA10102
CFA10102 Flexible OLED Display
The CFA10102 is a generic breakout board with three different electrical loops
– low voltage, high voltage (controlled by the variable resistor),and ground
(GNDA and GNDB are electrically connected). By soldering 0603 components on
the land patterns as specified below, the required circuit the display can
easily be created.

CFA10102| Function
---|---|---|---
1| VCC| On to HV
2.2uF to GNDB| Power Supply
Connect this pin the to high voltage loop using a solder blob or 0 ohm
resistor. Check that the HV loop is set to 12v (adjust using R3). For
reliability add capacitors between pin and ground.
2| VLSS| GNDB| Ground of Analog Circuit
This is an analog ground pin. Connect to one of the ground circuits
3| VSS| GNDB| Ground of Logic Circuit
This is a ground pin. It acts as a reference for the logic pins. Connect to
one of the ground circuits
4| CS#| Connect to MCU| Chip Select
This pin is the chip select input. The chip is enabled for communication only
when CS# is pulled low. Connect to
5| RES#| Connect to MCU| Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low. initialization of the
chip is executed. Keep this pin pulled high during normal operation.
6| SCLK| Connect to MCU| Serial Clock Input Signal
The transmission of information in the bus is low, initialization of the chip
is executed. Keep this pin pulled high during normal operation.
7| SOW| Connect to MCU| Serial Data Input Signal
This pin acts as a communication channel. The input data through SDIN are
latched at the rising edge of SCLK in the sequence of MSB first and converted
to 8-bit parallel data and handled at the rising edge of last serial clock.
SDIN is identified to display data or command by D/C# bit data at the rising
of the first SCLK.
8| VSS| GNDB| Ground of Analog Circuit
This is an analog ground pin. Connect to one of the ground circuits
9| VLSS| GNDB| Ground of Logic Circuit
This is a ground pin. It acts as a reference for the logic pins. Connect to
one of the ground circuits
10| VDD| LV| Power Supply for Logic
This is a voltage supply pin. Connect to LV loop.
11| N.C.| –| Reserved Pin
The N.C. pins between function pins are reserved for compatible and flexible
design.
12| VCOMH| 2.2uF to GNDB| Voltage Output High Level for COM Signal
This pin is the input pin for the voltage output high level for COM signals.
Connect a 2.2uF capacitor to ground
13| VCC| HV| Power Supply
Connect this pin the to high voltage loop using a solder blob or 0 ohm
resistor. Check that the HV loop is set to 12v
