1. Over View The display is a TFT active matrix electrophoretic display, with interface and a reference system design. The 2.7” active area contains 264 176 pixels, and has 1-bit white/black full display capabilities. An integrated circuit contains gate buffer, source buffer, interface, timing control logic, oscillator, DC-DC, SRAM, LUT, VCOM, and border are supplied with each panel. 2. Features • High contrast • High reflectance • Ultra wide viewing angle • Ultra low power consumption • Pure reflective mode • Bi-stable • Commercial temperature range • Landscape, portrait mode • Antiglare hard-coated front-surface • Low current deep sleep mode • On chip display RAM • Waveform stored in On-chip OTP • Serial peripheral interface available • On-chip oscillator • On-chip booster and regulator control for generating VCOM, Gate and source driving voltage • I2C Signal Master Interface to read external temperature sensor • Available in COG package IC thickness 280um 3.

The chip is enabled for MCU communication only when CSB is pulled Low. Note 5-2: This pin (DC) is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data will be interpreted as ／

data. When the pin is pulled Low, the data will be interpreted as command. Note 5-3: This pin (RST_N) is reset signal input. The Reset is active Low. Note 5-4: This pin (BUSY_N) is BUSY_N state output pin. When BUSY_N is low, the operation of chip should not be interrupted and any commands should not be issued to the module. The driver IC will put BUSY_N pin low when the driver IC is working such as: - Outputting display waveform; or - Programming with OTP - Communicating with digital temperature sensor Note 5-5: This pin (BS) is for 3-line SPI or 4-line SPI selection. When it is “Low”, 4-line SPI is selected. When it is “High”, 3-line SPI (9 bits SPI) is selected. Please refer to below Table.
