Product Description
The TOPWAY HMT101ATA-C is a 10.1-inch Smart TFT LCD module featuring an integrated 32-bit MCU and graphics engine, designed for industrial control systems, instrumentation, medical electronics, and power equipment applications.
With a 1024 × 600 pixel resolution and 65K colors (16-bit), this module provides a clear graphical display for equipment monitoring, control panels, and embedded user interfaces. It features a resistive touchscreen, allowing users to interact with displayed menus, buttons, and graphical elements.
Unlike conventional TFT displays that require the host controller to generate and manage all graphical content, the HMT101ATA-C includes an onboard display function controller and graphics engine. It supports TOPWAY TML files, allowing graphical interfaces, pictures, and icons to be designed in advance and stored in the module's internal Flash memory.
Communication with an external host controller is handled through a UART interface, allowing the host to send commands, update displayed values, and receive touch-key information. A separate USB interface is provided for downloading TML projects and image files.
The HMT101ATA-C is suitable for embedded applications that require a programmable graphical interface while reducing the processing and display-management workload of the main controller.

The resistive touchscreen supports user interaction through the module's predefined graphical interface.
2. Integrated MCU and Graphics Engine
The module incorporates an onboard 32-bit MCU and a dedicated display function controller with a graphics engine.
This allows the module to handle graphical interface operations internally, reducing the amount of display-related processing required from the external host controller.
Its graphics system supports pre-designed TML interface files, pictures, and icons stored in internal Flash memory.
3. TOPWAY TML Graphical Interface
The HMT101ATA-C supports TOPWAY TML files for creating and managing graphical user interfaces.
The general workflow is:
- Design the graphical interface using the TOPWAY Graphics Editor.
- Import pictures and create the user interface flow.
- Download the TML project and image files to the display through USB.
- Power on the module to run the stored graphical interface.
- Connect the external host through UART to exchange real-time data and commands.
The stored TML files define the interface flow and touch response, allowing the display to operate as a standalone graphical interface while exchanging data with the host controller.
4. UART Communication Interface
The UART interface (K1) is used for communication between the HMT101ATA-C and an external host controller.
It supports sending commands and data to the display and receiving information such as touch-key responses.
The connector provides:
| Pin | Signal | Function |
|---|---|---|
| 1, 2 | VDD | Power Supply |
| 3 | RTS (BUSY) | Busy Status Output |
| 4 | TX | Data Output |
| 5, 6 | RX | Data Input |
| 7, 8 | GND | Ground |
The RTS signal functions as a busy indicator:
- Logic 1: Busy.
- Logic 0: Not busy.
Hardware handshaking is recommended by the manufacturer.
Important: Although the product manual refers to this interface as UART, the electrical characteristics and included SMART LCD Command Manual specify RS232-C communication levels. It should not be connected directly to a 3.3V or 5V TTL UART without an appropriate interface.
5. USB Interface
The USB interface (K2) is used to preload TML project files and image files into the module.
| Pin | Signal | Function |
|---|---|---|
| 1 | VUSB | USB Power |
| 2 | D- | USB Data Negative |
| 3 | D+ | USB Data Positive |
| 4 | ID | USB Host/Client Identification |
| 5 | GND | Ground |
The USB interface supports project and image file downloading.
Important: The manufacturer specifically warns not to connect the USB terminal while the VDD supply at K1 is present. Follow the manual's connection instructions when programming the display.
6. Memory and Data Handling
The HMT101ATA-C uses internal Flash memory and RAM to manage graphical resources and real-time data.
- TML interface files, pictures, and icons are stored in Flash memory.
- Custom memory is stored in Flash and can be accessed through UART.
- VP variables are stored in RAM and support real-time data exchange with the host.
- The display controller processes host commands and reports touch-key information.
The manual specifies the following memory allocation:
| Memory Function | Memory Name | Allocated Space |
|---|---|---|
| 128-byte String | VP_STR | 128KB |
| 16-bit Number | VP_N16 | 64KB |
| 32-bit Number | VP_N32 | 64KB |
| 64-bit Number | VP_N64 | 64KB |
