The interface ecosystem offers distinct industry differentiation. As the first Allwinner 4K media SoC with complete standard CEC functionality, it features an HDMI 2.1 TMDS interface (no FRL high refresh rate, purely optimized for 4K 60Hz audio-visual scenarios).
The full CEC function enables unified linkage, one-key power on/off, and standby interconnection among TVs, players, and speakers, solving the compatibility defects of incomplete CEC support on previous Allwinner chips. It is ideal for integrated smart home audio-visual suites and unified commercial device management. The chip also integrates Gigabit Ethernet, USB 2.0, SPI, I2C, UART, 2.4G/5G dual-band Wi-Fi, and Bluetooth, enabling wired high-speed transmission and wireless flexible connectivity to lower hardware development and mass-production thresholds.
1.5 Stability & Heat Control: 24/7 Continuous Operation for Commercial Scenarios
Powered by a 22nm mature commercial process, the H626 does not pursue ultra-low power consumption like advanced 7nm/14nm chips. However, it delivers obvious power efficiency and heat reduction advantages compared with traditional 28nm/40nm set-top box and media SoC solutions.
Optimized by the power-efficient A55 architecture, the chip supports 7×24-hour stable operation with passive heat dissipation only, no fan required. Built-in multi-circuit protection, image noise reduction, dead pixel correction, and backlight compensation ensure stable performance during long standby and frequent start-stop cycles, extending terminal device service life. It also integrates AES and DES encryption algorithms to secure data transmission and storage.
