| Parameter | Specification | | :--- | :--- | | | Up to 240 (RGB) x 320 | | Color Depth | 262K colors (18-bit RGB) | | Interface Type | 8-bit, 9-bit, 16-bit, 18-bit parallel (8080/6800) + SPI | | Internal Memory | 172,800 bytes (GRAM) | | Operating Voltage (Logic) | 1.65V to 3.3V (I/O) | | Operating Voltage (Analog) | 2.5V to 3.3V | | On-chip Functions | DC-DC converter, Timing controller, Oscillator, Gamma correction | | Display Modes | Full color, 8-color (idle mode), Sleep mode | | Package | COG (Chip on Glass) / COF (Chip on Flex) | Interface Details The HX8872C is highly flexible. It supports both Intel 8080 and Motorola 6800 parallel bus modes. This means you can connect it directly to most MCU parallel buses without glue logic. Additionally, a 3-wire or 4-wire SPI interface is available for command transmission, though pixel data usually goes through the parallel bus for speed. Pin Configuration Understanding (Based on Datasheet) While the exact pinout varies by package, the hx8872c datasheet consistently groups pins into the following categories:
Introduction In the world of embedded systems, wearable tech, and small-screen interfaces, the driver IC behind the display is just as important as the microcontroller (MCU) running it. One such popular driver for small to medium-sized TFT-LCD panels is the HX8872C . hx8872c datasheet
// 6. Set Gamma curve (example - use datasheet values) write_command(0xE0); // Positive gamma write_data(0x0F); write_data(0x31); write_data(0x2B); /* ... more ... */
// 7. Inversion and frame rate (register 0xB1, etc.) This means you can connect it directly to
| Driver IC | Resolution | Interface | On-chip GRAM | Key Difference | | :--- | :--- | :--- | :--- | :--- | | | 240x320 | 8/16/18-bit + SPI | Yes | Mature, stable, good for QVGA | | ILI9341 | 240x320 | 4-line SPI + 8080 | Yes | More common in hobbyist community | | ST7789 | 240x320 | SPI only | Yes | Lower pin count, smaller package | | SSD1963 | Up to 800x480 | RGB parallel | No | Requires external frame buffer |
If you are an electronics engineer, a hobbyist, or a firmware developer searching for the , you likely need more than just a PDF link. You need a comprehensive breakdown of its features, pin configuration, command set, and application circuits. One such popular driver for small to medium-sized
