Texas Instruments ZigBee SoC CC2538 cracks intelligent lighting unified control problem
For wireless connectivity applications, TI has approximately 130 products and supports 14 wireless technologies. It can be said that TI has the industry's widest range of wireless connectivity products. TI's wireless connectivity product, the CC2538 System-on-Chip (SoC), is used in intelligent lighting systems to meet the latest needs of smart energy infrastructure, home building automation and intelligent lighting systems.
The CC2538 is a highly integrated ZigBee solution that integrates ARM Cortex M3 MCUs, memory and hardware accelerators on a single silicon chip, supports ZigBeePRO, ZigBee Smart Energy and ZigBee Home AutomaTIon as well as lighting standards for existing and future ZigBee products. Interoperability. In addition, the SoC supports IP standardization development using IEEE 802.15.4 and 6LoWPAN IPv6 networks for maximum flexibility and cost-effectiveness.
Upgrade the kernel to expand the range of chip applications:
In order to further meet the needs of networking and unified control in intelligent lighting, the CC2538 chip upgrades the MCU from 8 bits to 32 bits, and realizes efficient processing of the centralized network through the integrated ARM Cortex-M3 core, making it suitable for intelligent lighting systems. Play the role of a gateway. In the new Zigbee Light Link standard, the remote control of the smart luminaire is virtualized into a gateway, and the parameters such as on/off, brightness or color adjustment of the luminaire can be controlled by a remote control or a smart phone. Although ZigBee is a mesh network structure, it is difficult to have a ZigBee gateway in each room during the actual networking process of the smart home network. The intelligent lighting system using CC2538 and CC2530 chips solves this problem well. The luminaires with the CC2530 chip are relatively inexpensive and can be installed in each room and function as a router. A luminaire equipped with a CC2538 chip is ideal for use as a gateway device.
Support for more protocols: With 128K to 512K of expandable flash memory option, the CC2538 can support more protocol stacks, such as ZLL lighting protocols, standard home intelligence protocols, and even support the Smart Energy protocol stack commonly used in North America. The processing power is very powerful.
High security: With AES-128/256, SHA2 integrated hardware encryption engine, optional ECC-128/256 and RSA hardware acceleration engine, CC2538 improves the security level of the system and reduces the energy consumption of secure key exchange.
Low Power : The CC2538 is optimized for battery-powered applications with a current usage of only 1.3uA in sleep mode.
In addition, with an integrated pin-to-pin compatible 8K to 32K RAM option, the CC2538 offers maximum flexibility to support mesh networks with up to hundreds of end nodes. Most notably, the CC2538 can safely operate at temperatures up to 125 ° C.
The dynamic nature of smart energy, home automation, and lighting systems dictate the need for high performance and flexibility to meet manufacturers' needs for different memory, security, and standards support. Not only is the CC2538 highly integrated, but it also supports ZigBee and other IP-based standards such as 802.15.4 and 6LoWPAN IPv6, which meet the needs of smart energy infrastructure, home building automation, and intelligent lighting systems.
