Intel protege pitches wireless SoC for IoT

January 19, 2016 // By Peter Clarke
Fabless chip company Telink Semiconductor Co. Ltd. (Shanghai, China) has launched the TLSR8269 a system-on-chip intended to provide low power wireless connection for the Internet of Things applications in the smart home.

Telink, which was founded in 2010 and received venture capital backing from Intel in 2015, claims the chip supports all 2.4GHz IoT communication standards. This includes a proprietary Bluetooth Low Energy mesh communications technology that has been adopted by lighting customers in the US and China. With the ability to integrate security, voice search, touch control and other factors, the TLSR8269 is suitable for human interface devices ranging from smart home applications to wireless toys.

The TLSR8269 combines the radio frequency (RF), digital processing, protocols stack software and profiles for Bluetooth Smart, BLE Mesh, 6LoWPAN, Thread, Zigbee, RF4CE, HomeKit and 2.4GHz proprietary standard support in a single SoC.

The TLSR8269’s 512kbytes of on-chip flash memory enables multiple functionalities to be embedded in the chip with end-product functionality configurable via software. The TLSR8269 can support over-the-air upgrades and product feature rollouts. 

The TLSR8269 can “concurrently” run two standards – for example, Bluetooth Smart and ZigBee/RF4CE – enabling products to bridge the smartphone and home automation world with a single chip and no requirement for an external hub. Security is supported with hardware acceleration required by HomeKit, Thread and other standards without the requirement for an external DSP. 

The TLSR8269 supports analog and digital microphones and audio output with enhanced voice performance for voice search and other such applications. The TLSR8269 also includes on-chip peripherals for interfacing with external components such as LEDs, sensors, touch controllers, keyboards, and motors.  

"It will change the face of IoT, enabling end products to be built with a single chip that rules all standards," said Wenjun Sheng, CEO of Telink, in a statement.
