Zeratul ‐ Atlas ‐ Tassadar - themactep/thingino-firmware GitHub Wiki

The Ingenic Zeratul, Atlas, and Tassadar platforms are a series of System-on-Chip (SoC) solutions designed primarily for battery-powered IoT cameras and smart home devices. The platforms emphasize low power consumption while maintaining persistent Wi-Fi connectivity.

Features

  • Persistent Wi-Fi Connectivity: Maintains a stable network connection even in low-power states
  • Extended Battery Life: Power management design allows devices to operate for 6+ months on battery power / solar panels
  • Remote Access: Always-available remote viewing capabilities
  • Power Management: Uses external micro-controllers for sophisticated power management
  • Fast Start: Achieve sub 300 TTFF (time to first frame) cold start time

Hardware Architecture

The platform typically employs a two-chip design:

  1. Main Ingenic Zeratul/Atlas/Tassadar SoC
  2. External micro-controller for power management (sometimes integrated in the Wi-Fi module)

Product Lines

  • T32 (Codename: Tassadar)
  • T41 (Codename: Atlas)
  • T31 (Codename: Archon)
  • T20 (Codename: Immortal)

Power Management

Power efficiency is achieved through:

  • Dynamic frequency scaling
  • Multiple power states
  • Sophisticated wake-up mechanisms
  • External micro-controller management of power states

Third-Party Support

Due to the wide variation in:

  • Power management micro-controller choices
  • Wi-Fi module integrations
  • Custom hardware designs

Third-party firmware like Thingino cannot currently provide universal support for low power devices. Each device requires specific power management micro-controller code tailored to its hardware configuration.
