Product catalog summary

Basic Specification
The TOPWAY HMT050ATA-2C is a Smart TFT Module with a 32-bit MCU and graphics engine supporting TOPWAY TML 3.0, suitable for industrial, medical, and power electronics applications. It features a 5.0” screen, 800x480 resolution, 65k color depth, and operates between -20 to +70°C.

Absolute Maximum Ratings
Power supply voltage ranges from -0.3 to 26.0 V. Operating and storage temperatures are -20 to 70°C and -30 to 80°C, respectively. Exceeding these limits may cause damage.

Electrical Characteristics
Operates at 5.0 to 26.0 V with typical currents of 180 mA for VDD and 175 mA for USB.

Function Specifications
Supports TML, picture, and ICON files in FLASH memory, with real-time access via UART and custom memory access by the HOST.

Optical Characteristics
Viewing angle is 60-70 degrees, contrast ratio is 400-500, with response times of 10-20 msec for Tf and 15-30 msec for Tr.

Design and Handling Precautions
Ensure adjustable V0 and VCOM for contrast, avoid exceeding maximum ratings, and maintain a static-free environment. Store at 0-40°C and <80% RH, away from sunlight and harmful gases.

CTP Mounting Instructions
Bezel window should be larger than the CTP active area with a gasket between bezel and CTP. Support brackets are recommended for slim modules.
