Jennic公司的IEEE802.15.4 和ZigBee无线微控制器JN513x系列是低功耗低成本的无线微控制器,适用于IEEE802.15.4 和ZigBee的应用.每个器件集成了32位RISC处理器,以及完全兼容IEEE802.15.4 的2.4GHz收发器,192KB ROM,从8KB到96KB可选择的RAM与丰富的模拟和数字混合外设.本文描述了解决方案的主要特性,方框图以及所用的评估板的性能以及应用电路图.

The JN513x are a family of low power, low cost wireless microcontrollers suitable for IEEE802.15.4 and ZigBee applications.Each device integrates a 32-bit RISC processor, with a fully compliant 2.4GHz IEEE802.15.4 transceiver, 192kB of ROM, a selection of RAM sizes from 8kB to 96kB, and a rich mixture of analogue and digital peripherals.

The cost-sensitive ROM/RAM architecture supports the storage of system software, including protocol stacks, routing tables and application code/data.Each device integrates hardware MAC and AES encryption accelerators, power saving and timed sleep modes, and mechanisms for security key and program code encryption.These features all make for a highly efficient, low power, single chip wireless microcontroller for battery-powered applications.

应用方框图:

The JN513x devices require a minimum of external components to support wireless applications; a crystal, some decoupling components and printed antenna are all that is
required for the lowest cost bill of materials and smallest size (an external bootloader flash may be used for optional program code storage).
