7.8" Color ePaper Display, 1404×1872 B/W, MCU Interface
SKU: DMAYE0780X8NADMAYE0780X8NA is a 7.8-inch color reflective electrophoretic display module with integrated source and gate drivers. The datasheet specifies 1404×1872 at 300 PPI for black-and-white operation and 702×936 at 150 PPI for color operation, with support for 4096 colors.
The datasheet identifies reflective and bi-stable operation, an MCU interface, and intended use in portable electronic devices such as e-book readers. Image updates require the published logic, gate, source, and common-voltage supplies together with the specified power sequence.
Document basis: DMAYE0780X8NA Product Specification, Version V1.0.0, dated Mar 8, 2025. Use the latest official datasheet and mechanical drawing when confirming the final product design.

Optical Measurement Conditions and Published Values
The optical table is based on reflective measurements made with illumination at 45 degrees and detection perpendicular to the display surface. The datasheet states a 25°C measurement condition, an 85 Hz frame condition, and BYK measurement equipment.
Reflective Optical Data
The published reflectivity and contrast values apply to the illumination, viewing geometry, temperature, frame condition, and measurement equipment stated in the datasheet.
Published CIE L*a*b* Coordinates
The color coordinate values below are reproduced from the datasheet and apply to the stated measurement conditions. The datasheet does not publish a color-gamut percentage.
Electrical Rails and Power Sequencing
The electrical table lists separate logic, gate, source, and common-voltage supplies. IVDD is 5.8 mA typical at VDD = 3.3 V and applies only to the logic supply. Typical module power and standby power are both listed as TBD.
Published Power Sequence
The datasheet states that the published power-on and power-off order must be followed to prevent latch-up. The rail cards below reproduce the voltage values listed in the electrical table.
40-Pin MCU Interface and Signal Groups
The datasheet identifies the interface as MCU and defines a 40-pin connection. The pinout includes D0-D15, source and gate timing signals, VDD/VSS, VGH/VGL, VPOS/VNEG, VCOM, and VBORDER. SPI and I2C are not listed.
Parallel Data Path
D0-D15 provide 16 source-driver data signals. The same connection also carries CLK, CPV, STV, SPH, LE, OE, GMODE1, power rails, ground, VCOM, and VBORDER.
For the 1404×1872 timing configuration, the table lists SDCK at 38 MHz, 8 pixels per SDCK, and FR at 86 Hz. Check controller compatibility against the complete timing diagrams.
Mechanical Drawing and FPC Details
The mechanical drawing title block lists DMAYE0780X8NA, revision RV1.0, dated 2024.03.16. Use the drawing to confirm panel orientation, active-area alignment, FPC position, contact geometry, module thickness, and enclosure opening dimensions.
Connector matching: The supplied datasheet does not identify a mating connector part number. Confirm the FPC contact geometry, connector orientation, and mating connector before finalizing the PCB layout.
Using the drawing: Review the active area, outer dimensions, FPC region, detail views, reference dimensions, and unspecified tolerance note together rather than relying only on the summary dimensions.
Operating Conditions and Reliability Tests
The datasheet lists the environmental and packaged-shipment test conditions below. Package vibration and drop tests are specified for the fully packed shipment, not as bare-module impact ratings.
Published Use Range
Operation: 0°C to 50°C and 0% to 70% RH.
Storage: -20°C to 70°C and 30% to 60% RH.
The reliability table states that electrical, mechanical, and optical specifications shall be satisfied at the end of testing.
High-temperature operation: +50°C, 30% RH, 240 hours.
Low-temperature operation: 0°C, 240 hours.
High-temperature storage: +70°C, 23% RH, 168 hours.

Common Questions Before Ordering
Does 300 PPI apply to color operation?
No. The datasheet specifies 1404×1872 at 300 PPI for black-and-white operation and 702×936 at 150 PPI for color operation.
Does 5.8 mA represent total module power?
No. It is the typical IVDD logic-supply current at VDD = 3.3 V. The electrical table also lists VGH, VGL, VPOS, VNEG, and VCOM, while typical module power and standby power remain TBD.
Is touch specified in the datasheet?
No touch panel or touch controller specification is provided. Confirm any required touch solution separately before ordering.
Is the 450 ms update time specified for every mode?
The electrical table lists 450 ms typical at 25°C. It does not provide a separate guaranteed value for each black-and-white or color mode, so the waveform and controller conditions should be confirmed for the intended implementation.
What does the MCU interface require?
The 40-pin definition includes D0-D15, multiple timing signals, logic and drive supplies, ground, VCOM, and VBORDER. Confirm that the selected controller and power circuit support the published pinout and timing.
Is a mating connector part number listed?
No mating connector part number is listed. Use the mechanical drawing to confirm the FPC contact geometry and orientation before selecting the connector and releasing the PCB.
Which compliance marks are listed?
The supplied datasheet marks RoHS with a check and marks CE, FCC, and Other with an X. Confirm any project-specific compliance documents separately.
Does the datasheet provide a usable firmware link?
The firmware section states “see github link,” but the supplied file does not provide a usable download URL. Confirm any controller, waveform, firmware, or integration resources separately.
