JN5139 Wireless Microcontroller (IEEE802.15.4 and JenNet) 

 

The JN5139 is a low power, low cost wireless microcontroller suitable for IEEE802.15.4 and JenNet applications. The device integrates a 32-bit RISC processor, with a fully compliant 2.4GHz IEEE802.15.4 transceiver, 192kB of ROM, 96kB of RAM, 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. An external flash memory is used to store application code that is bootloaded into internal RAM and executed at runtime.

The 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.
