Description
(default) OLED Logic Circuit + Boost converter + OLED panel are powered from VDD
(pin #2). This allows the full module to be powered by a single low-voltage supply.

Boost converter + OLED panel are powered from BC_VDD (pin #3). OLED Logic Circuit
is powered from VDD (pin #2). This allows for increased efficiency through the boost
converter, by allowing a supply voltage up to +12V at its input, BC_VDD (pin #3).

Description
OLED panel is powered from VCC (pin #15) – boost converter is not used.
OLED Logic Circuit is powered from VDD (pin #2). This allows for maximum module
efficiency, and drastically reduced total current consumption.

Description
See Description

OLED Internal Regulator + Logic Circuit are powered from G_VDD (pin #18) – boost
converter is powered from VDD (pin #2). Disabling the internal regulator reduces
power consumption. Booster circuit must be driven by alternative method.

Note: Lifetime at typical temperature is based on accelerated high-temperature operation. Lifetime is tested at
average 50% pixels on and is rated as Hours until Half-Brightness. The Display OFF command can be used to extend
the lifetime of the display. Luminance of active pixels will degrade faster than inactive pixels. Residual (burn-in)
images may occur. To avoid this, every pixel should be illuminated uniformly.

MPU Interface
6800-MPU Parallel Interface
The parallel interface consists of 8 bi-directional data pins, R/W, D/C, E, and /CS.
A LOW on R/W indicates write operation, and HIGH on R/W indicates read operation.
A LOW on D/C indicates “Command” read or write, and HIGH on D/C indicates “Data” read or write.
The E input serves as data latch signal, while /CS is LOW. Data is latched at the falling edge of E signal.

8080-MPU Parallel Interface
The parallel interface consists of 8 bi-directional data pins, /RD, /WR, D/C, and /CS.
A LOW on D/C indicates “Command” read or write, and HIGH on D/C indicates “Data” read or write.
A rising edge of /RS input serves as a data read latch signal while /CS is LOW.
A rising edge of /WR input serves as a data/command write latch signal while /CS is LOW.

Serial Interface (4-wire)
The 4-wire serial interface consists of serial clock SCLK, serial data SDIN, D/C, and /CS.
D0 acts as SCLK and D1 acts as SDIN. D2 should be left open. D3~D7, E, and R/W should be connected to GND.

SDIN is shifted into an 8-bit shift register on every rising edge of SCLK in the order of D7, D6,…D0.
D/C is sampled on every eighth clock and the data byte in the shift register is written to the GDRAM or
command register in the same clock. Note: Read is not available in serial mode

Serial Interface (3-wire)
The 3-wire serial interface consists of serial clock SCLK, serial data SDIN, and /CS.
D0 acts as SCLK and D1 acts as SDIN. D2 should be left open. D3~D7, E, R/W, and D/C should be connected to
GND.

SDIN is shifted into an 9-bit shift register on every rising edge of SCLK in the order of D/C, D7, D6,…D0.
D/C (first bit of the sequential data) will determine if the following data byte is written to the Display Data
RAM (D/C = 1) or the command register (D/C = 0). Note: Read is not available in serial mode
