JN5139 Wireless Microcontroller

Not recommended for new designs, use JN5148 products

 

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.
