Texas Instruments (TI) has announced the launch of the CC2538 System-on-Chip (SoC) to simplify the development of smart energy infrastructure, home building automation, and intelligent lighting gateways that support ZigBee® wireless connectivity. The industry's most highly integrated ZigBee solution, the CC2538, integrates ARM® CortexTM-M3 MCUs, memory, and hardware accelerators on a single silicon chip and is extremely cost-effective. The CC2538 supports ZigBeePRO, ZigBee Smart Energy and ZigBee Home Automation, and lighting standards that enable interoperability with existing and future ZigBee products. In addition, the SoC also supports IP standardization development using IEEE 802.15.4 and 6LoWPAN IPv6 networks for maximum flexibility. Low temperature lithium battery refers to the working temperature under - 20 ℃,to meet different environment and temperature. YFJ company has designed a lot of this kind of Low Temperature Battery with our own advantages.
1.Dual IC chips, that can anti-shortcircuit, anti-overcharger, anti-overcurrent, anti-overload
2.Widely using temperature range, lower temperature Lithium Battery can be operated in -50°C~+60°C
3.Long
cycle life, more than 500 charge/discharge cycles (0.2C)( 80% capacity remained
). more than 800 times(0.1C charge/discharge
4.The Battery Pack has a high cycle life, which conforms
to the values of low carbon, energy saving and environmental protection
