Overview
The Noritake Itron CU20029-UW1J is a 20×2 character VFD (vacuum fluorescent display) module designed for industrial automation, control systems, and embedded applications. This CU20029-UW1J module combines a high-contrast green-blue display with a built-in controller and parallel interface, making it a reliable solution for real-time parameter display in factory floors, process control equipment, and test instrumentation.
Key Features
- 20×2 alphanumeric character display with 5×7 dot matrix and international ANK format
- Green (blue-green) vacuum fluorescent illumination with 350 cd/m² minimum luminance for visibility in bright conditions
- Small 9.2mm character size (3.8mm × 9.2mm) for compact panel integration
- Built-in controller with parallel interface (DB0–DB7 data lines, control signals)
- 5V single supply operation (4.75V to 5.25V range)
- Low 400 mA maximum current consumption
- Wide operating temperature range: −40°C to +85°C
- 20-pin DIP connector for easy integration
- RoHS compliant
