Hx8872-c Datasheet [ LATEST ]

Finding an authentic, complete datasheet can be frustrating because Himax does not always publish directly to mainstream sites. Here are reliable sources:

Warning: Avoid “datasheet catalogs” that require registration or credit cards. The HX8872-C datasheet is an engineering document and should be free.

For reliable operation, maintain these conditions:

| Parameter | Conditions | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | :--- | | VDDIO | I/O supply | 1.7 | 1.8 or 3.3 | 3.6 | V | | VDDC (Core) | External or internal LDO | 1.14 | 1.2 | 1.26 | V | | PCLK Frequency | RGB input | 10 | 50 | 80 | MHz | | MIPI Lane Rate | Per lane | 80 | 400 | 500 | Mbps | | Operating Temp | Commercial grade | -20 | 25 | 70 | °C | | Operating Temp | Industrial grade | -40 | 25 | 85 | °C | hx8872-c datasheet

The HX8872-C’s logic inputs are not 5V tolerant. Feeding it 5V from an Arduino Uno (without level shifters) will cause overheating and irreversible damage. Use 3.3V logic or bi-directional level converters.

Based on the datasheet’s reference design, here is a conceptual code snippet (using RGB interface mode):

// Assume LCD_RST, LCD_CS, LCD_RS (D/C) defined
void HX8872C_Init(void) 
    // Hardware reset
    HAL_GPIO_WritePin(LCD_RST_GPIO_Port, LCD_RST_Pin, GPIO_PIN_RESET);
    HAL_Delay(10);
    HAL_GPIO_WritePin(LCD_RST_GPIO_Port, LCD_RST_Pin, GPIO_PIN_SET);
    HAL_Delay(120);

// Send commands via SPI or MCU interface
WriteCommand(0x11);  // Sleep out
HAL_Delay(120);
WriteCommand(0x36);
WriteData(0x00);     // Normal orientation
WriteCommand(0x3A);
WriteData(0x05);     // 16-bit RGB
WriteCommand(0x29);  // Display on





// Then configure LTDC peripheral for RGB interface:
// HSYNC = 10, HBP = 20, HFP = 10, VSYNC = 2, VBP = 2, VFP = 2
// Pixel clock = 9MHz

Exceeding these values will damage the HX8872-C. Finding an authentic, complete datasheet can be frustrating

| Parameter | Symbol | Min | Max | Unit | | :--- | :--- | :--- | :--- | :--- | | I/O Supply Voltage | VDDIO | -0.3 | 3.96 | V | | Core Supply Voltage | VDDC | -0.3 | 1.32 | V | | Input Voltage on RGB pins | VIN | -0.3 | VDDIO+0.3 | V | | Storage Temperature | Tstg | -40 | +125 | °C | | ESD (Human Body Model) | HBM | -2 | +2 | kV |

In the world of display interface ICs, the bridge between legacy parallel RGB signals and modern high-speed serial interfaces is critical. The HX8872-C is one such specialized integrated circuit designed to act as a bridge, converting RGB (24-bit parallel) to MIPI DSI (Display Serial Interface) .

If you are searching for the hx8872-c datasheet, you are likely working on a project involving a small-to-medium sized LCD panel (typically 480x854 to 720x1280 resolution) that requires a high-speed, low-power serial interface. This article consolidates the critical technical data typically found in the official datasheet, including electrical characteristics, pin configuration, timing diagrams, and reference design guidelines. including electrical characteristics
