8x2 Character LCD FSTN Transflective – MCU
DM-LCD0802-416 is an 8-character by 2-line FSTN positive transflective LCD module designed for embedded systems. Powered by the ST7066U controller, it supports 6800-series MPU parallel interface in 4-bit or 8-bit mode for straightforward MCU integration.
The module operates at 5V logic with a compact 58.0 × 32.0 × 13.2 mm footprint and a 6:00 view direction. The FSTN positive transflective structure supports readability under ambient light, while the white LED backlight assists viewing in low-light conditions.

FSTN Transflective Display Technology
Three design characteristics define the DM-LCD0802-416 module and its suitability for embedded character display applications.
FSTN Positive Transflective Mode
The Film Super-Twisted Nematic (FSTN) positive transflective display supports readable output under both ambient light and backlight illumination. The transflective construction uses ambient light in bright environments and transmits the white LED backlight in low-light environments.
Built-in Character Generator ROM
The ST7066U controller integrates a character generator ROM and supports 5 × 8 dot font operation for two-line display mode. The controller also provides 5 × 11 dot font capability for applicable one-line configurations. Custom characters can be created using the CGRAM area.
6:00 View Direction with 1/16 Duty
The module is specified with a 6:00 viewing direction (bottom view) and 1/16 duty drive. The optical table specifies view angles of 30° top, 60° bottom, 45° left, and 45° right.

Engineering Notes
The following items should be reviewed before PCB layout, sample evaluation, and product integration. Confirm all details with the datasheet and the DisplayModule engineering team.
Contrast Adjustment
The VO pin (pin 3) requires an external contrast adjustment circuit, typically a potentiometer between VDD and VSS. Confirm the optimal VO voltage for your application during sample evaluation.
Interface Mode Selection
The module supports 8-bit and 4-bit MPU interface modes, selected via the Function Set instruction (DL bit). In 4-bit mode, data is transferred in two nibbles via DB4–DB7. Review the initialization sequence for your chosen mode in the datasheet.
Backlight Drive
The white LED backlight is driven through pins 15 (A, anode) and 16 (K, cathode) at 3.5V typical (3.4 to 3.6V) with 32 mA typical current (40 mA max). Confirm current limiting requirements for your design.
Initialization Sequence
Follow the instruction-based initialization sequence specified in the datasheet for 8-bit or 4-bit mode (fosc = 270 KHz). Incorrect initialization may result in display malfunction. Check the busy flag (BF) before sending subsequent instructions when R/W read operation is available; otherwise use sufficient fixed delays according to the instruction timing requirements.
View Direction and Mounting
The module is specified with a 6:00 view direction (bottom view). Confirm the mounting orientation in your product enclosure to match the intended viewing angle.
