Rockchip RK3539 quad-core Cortex-A55 SoC shows up in low-cost Android 14 4K TV stick with AV1 codec support

HS89 T15 4K Android TV stick is powered by the new Rockchip RK3539 quad-core Cortex-A55 SoC with AV1 and H.265 video codecs and HDR10 support, and is equipped with up to 4GB of RAM and a 32GB eMMC flash.

The device features a male HDMI 2.1 port, WiFi 6 and Bluetooth 5.4 connectivity, a USB Type-A host port, and a USB-C port for power only, either directly from the TV or through a 5V/2A power adapter. The device also ships with a Bluetooth voice remote control. Let’s have a look at both the streaming device and the RK3539 chip itself since the datasheet is available.

HS89 T15 TV stick

Let’s start with the HS89 T15 TV stick’s specifications:

SoC – Rockchip RK3539
- CPU – Quad-core Cortex-A55 @ 1920 MHz
- GPU – Mali-310
- VPU – 4Kp60 AV1, H.265, H.264 video decoding
System Memory/Storage options
- 2GB RAM, 16GB eMMC flash
- 4GB RAM, 32GB eMMC flash
Video Output – HDMI 2.1 port up to 4Kp60 with HDR10 support
Audio – Digital audio via HDMI
Connectivity – WiFi 6 and Bluetooth 5.4
USB – 1x USB Type-A port
Misc – 3.5mm jack for IR extender
Power Supply – 5V DC/2A via USB-C port
Dimensions – 100 x 33 x 13 mm
Weight – TBD

The TV stick ships with an HDMI cable, a Bluetooth and IR remote control with voice control support, and a user manual. It runs Android 14 with Google Play Store support, but there’s no mention of DRM certifications such as Widevine L1, so it may not be for everyone.

The HS89 T15 TV stick is sold on AliExpress for $33.72 in its 2GB/16GB configuration, while the 4GB/32GB model goes for $44.96. Note that it doesn’t ship with a 5V/2A power supply, and you may need one if your TV’s USB port doesn’t output enough power. The IR extender doesn’t appear to be included either. If you are not into the TV stick form factor, VONSTAR HS89 PRO 15 TV box sells for about $30 (2GB/16GB) or $40 (4GB/32GB) on AliExpress.

Unsurprisingly, the specifications are very similar to those of the Rockchip RK3538 SoC we covered a few months ago. The main differences are support for 4K video output and decoding, a Gigabit Ethernet MAC, and support for up to 4GB of RAM (vs 2GB) for the RK3539 processor. Despite the differences, the RK3538 and RK3539 have the same number of balls (434) and dimensions. You’ll find more details in the datasheet on the Rockchip.fr website.
