Product Description

 

 

Professional-Grade 20x4 LCD for Industrial & Embedded Systems
 

The SFBM2004HX-A-Y is a high-reliability 20×4 character LCD module engineered for demanding applications in automation, medical devices, and laboratory equipment. Operating at 3V with ultra-low power consumption (0.15mA typ.), it delivers exceptional performance across industrial temperature ranges (-20°C to +70°C).

 

Key Technical Advantages

  • SPLC780D Controller Compatibility:Seamless integration with industry-standard HD44780 protocols—accelerate development with existing code libraries and reference designs.
  • Superior Optical Performance:STN Yellow/Green transflective display with 6 o’clock viewing angle ensures clarity under ambient lighting. Backlight uniformity >75% (100 cd/m² typ.) eliminates hot spots.
  • Engineered for Harsh Environments:
  1. ESD Hardened: ±8kV air/±4kV contact discharge protection
  2. Validated per MIL-STD-105E (Major Defect AQL 0.4)
  3. Humidity resistant (20-90% RH non-condensing)

Technical Specifications Deep Dive

  • Timing Control: 270kHz oscillator, 450ns E-pulse width (Write Mode)
  • Memory Mapping: DDRAM addresses support 4-line wraparound (Hex: Line1=00-13, Line2=40-53)
  • Electrical Safety: VDD=2.8-3.5V, VLCD=VDD-12V to VDD-0.3V
  • Mechanical Precision: 0.56mm dot pitch, 98×60mm footprint with 13.2mm max. thickness

 

Compliance & Longevity

  • Full ROHS 2011/65/EU, REACH 1907/2006/EC compliance
  • 1-year warranty with >120hrs validation in thermal cycling (-30°C↔80°C) and vibration tests (10-55Hz XYZ axis)
