Industrial-Grade E-Paper for Sustainable Solutions

The SFE154QXBW-7284AN is a 1.54" monochrome E-ink display engineered for ultra-low-power applications in IoT devices, industrial sensors, and portable medical instruments. Leveraging electrophoretic technology with bi-stable performance (zero power to retain images), it delivers 35% reflectivity and 180° viewing angles – ideal for sunlight-readable deployments in harsh environments (0°C to +50°C).

Core Differentiators for Design Engineers

1. Dual SPI Flexibility & Advanced Control

  • Configurable 3-wire (9-bit) or 4-wire (8-bit) SPI via BS1 pin (Page 7), compatible with ARM Cortex-M/R, ESP32, and Raspberry Pi Pico.

  • Integrated waveform LUT optimization (Command 0x32) and VCOM OTP programming (Command 0x2A) for flicker-free updates and temperature compensation.

2. Ultra-Low Power Architecture

  • Deep Sleep Mode at 1–5 µA (Command 0x10) extends battery life in always-on applications.

  • Partial refresh (0.3 sec) minimizes energy consumption during dynamic data updates.

3. Robust Environmental Tolerance

  • Validated for 240 hrs at -25°C/+60°C storage, 80% RH humidity, and ±8kV ESD.

  • Anti-glare hardened surface resists scratching in high-traffic industrial settings.

Engineering Resources & Integration

  • Pre-tested initialization sequence reduces development time:

  • Compliance for EU/US Markets

◾ RoHS 3 (EU 2015/863), REACH SVHC, and Halogen-Free certified.
◾ Packaging meets EU 2025/40 recyclability standards (effective 2026).

Target Applications

  • Industrial: HVAC controls, warehouse logistics tags

  • Medical: Portable diagnostic devices, medication trackers

  • Retail: Electronic shelf labels (ESLs), smart price tags

  • Smart City: Parking sensors, environmental monitors
