Product Brief - JN5139 IEEE802.15.4 and ZigBee Wireless Microcontrollers Overview The JN5139 is a low power, low cost wireless microcontroller suitable for IEEE802.15.4 and ZigBee 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. Features: Transceiver * 2.4GHz IEEE802.15.4 compliant * 128-bit AES security processor * 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. MAC accelerator with packet formatting, CRCs, address check, auto-acks, timers * Integrated power management and sleep oscillator for low power * 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.

Used effectively, these will allow a batteries life expectancy for a typical remote sensing application, to be of the order of a few years. Typical Current Power Saving Mode Deep sleep 0.2A Sleep: wakeup on I/O or timer event 1.3A Sleep: wakeup on I/O or timer event and 96kB RAM retained 3.3A Wireless Protocol Stacks in ROM Two standard ROM configurations are available that integrate IEEE802.15.4b and ZigBee protocol stacks. The JN5139-000 integrates IEEE802.15.4b for development of proprietary systems, and the JN5139-Z01 integrates the ZigBee protocol stack, this supporting co-ordinator, router and end device configurations. Custom ROM masks will support the integration of user code into ROM, attractive to higher volume applications. Vcc Timers Two Wire Serial Port The JN5139 device requires 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).
