Description
WF35PTIBCDBT0 is a 3.5-inch Resistive Touch TFT LCD Module with a resolution of 320x240 pixels and an aspect ratio of 4:3. Its module dimensions are 93.5 x 66.44 mm, and the active area size is 70.08 x 52.56 mm. This module features a control board and a built-in RA8875 controller IC with 8080 MPU interface support.
Winstar P Series TFT Display Features:
- The TFT display module primarily employs the RA8875 Controller IC, which is integrated with a standardized 36-pin MCU 8080 8/16-bits Pin define, and 8/16-bits 6800 Pin define Interface can be selected through Jump.
- Pin no. 33 ~ 36 are pre-defined as backlight supply, eliminating the need for designing extra backlight circuitry.
- Users can request external expansion of Chinese fonts (optional) and flash memory.
- Through the built-in PWM Command of the RA8875 IC, backlight control and DMA (Direct Memory Access) for accelerated graphical operations are facilitated.
- Additionally, it integrates a built-in 4-wire resistive touch panel controller, which is only applicable to P Series TFT models equipped with resistive touch.
The WF35PTIBCDBT0 TFT LCD module with resistive touch panel has a contrast ratio of 350:1 and a brightness of 300 nits (typical value). LCM voltage ranges from 3V-3.6V, typical value is 3.3V. Operating temperature covers from -20~+70℃, storage temperature range is from -30~+80℃.
