Ta=25°C, 50%
checkerboard 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. [8] 7. Font Content Address Table # Type Font Content Character Set

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

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.

The Multi‐Font device is enabled by a high‐to‐low transition on /MF_CS2. /MF_CS2 must remain LOW for the duration of any command‐in or data‐out sequence. The Font Address is shifted in on the MF_SI line on the rising edge of MF_SCLK. The Font Data is shifted out on the MF_SO line on the falling edge of MF_SCLK. [16] 12.2.

Address Bytes 3
Dummy Bytes 1
Data Bytes 1 ~ ∞ READ mode supports up to 30MHz frequency on MF_SCLK. READ mode outputs the data starting from the specified address location. The data output stream is continuous through all addresses until terminated by a low‐to‐high transition on /MF_CS2. The internal address pointer will automatically increment after each byte is read. READ instruction is initiated by executing an 8‐bit command [0x0B] on the MF_SI line, followed by the desired font address bits [A23‐A0], and followed by an 8‐bit dummy write [0x00]. The font data will then be output on MF_SO line, MSB first. /MF_CS2 must remain active LOW for the duration of the read cycle. [17] 12.3.
