This allows the full module to be powered by a single low-voltage supply. Jumper Option #1 - Independent Supply Voltage for Boost Converter (BC_VDD) R14 R15 R18 R1 Description Open Close Open Open 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). Jumper Option #2 – External Supply Voltage for OLED Panel (VCC) R14 R15 R18 R1 Open Open Close Open 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. Jumper Option #3 – External Supply Voltage for Internal Regulator (G_VDD) R14 R15 R18 R1 Description See Description Close 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. 7 Controller Information Built in SSD1322 Controller For detailed information please download datasheet: https://support.newhavendisplay.com/hc/en-us/articles/4414477846679-SSD1322 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. Function Write Command Read Status Write Data Read Data E ↓ ↓ ↓ ↓ R/W 0 1 0 1 /CS 0 0 0 0 D/C 0 0 1 1 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. Function Write Command Read Status Write Data Read Data /RD 1 ↑ 1 ↑ /WR ↑ 1 ↑ 1 /CS 0 0 0 0 D/C 0 0 1 1 Alternatively, /RD and /WR can be kept stable while /CS serves as the data/command latch signal. Function Write Command Read Status Write Data Read Data /RD 1 0 1 0 /WR 0 1 0 1 /CS ↑ ↑ ↑ ↑ D/C 0 0 1 1 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. Function Write Command Write Data /RD Tie LOW Tie LOW /WR Tie LOW Tie LOW /CS 0 0 D/C 0 1 D0 ↑ ↑ 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 8 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. Function Write Command Write Data /RD Tie LOW Tie LOW /WR Tie LOW Tie LOW /CS 0 0 D/C Tie LOW Tie LOW D0 ↑ ↑ 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).
