Trade.Information

Product Name: JN5121 Wireless Microcontroller (IEEE802.15.4 and ZigBee)

Product Description

Highlights

• Single chip solution
• Integrated 2.4GHz transceiver
• 32-bit RISC CPU - 3MIPs/mA
• Fully compliant with IEEE802.15.4
• Rich user preipherals
• Low power solution
• Highly security AES encryption

The JN5121 is the first in a series of low power, low cost IEEE802.15.4 compliant wireless microcontrollers. Combining an on chip 32-bit RISC core, a fully compliant 2.4GHz IEEE802.15.4 transceiver, 64kB of ROM and 96kB of RAM, provides a versatile low cost solution for wireless sensor networking applications.  The high level of integration helps to reduce the overall system cost.  In particular, the ROM enables integration of point-to-point and mesh network stack protocols, and the RAM allows support of router and controller functions without the need for additional external memory.

The JN5121 uses hardware MAC and highly secure AES encryption accelerators for low power and minimum processor overhead.  Integrated sleep oscillator and power saving facilities are provided, giving low system power consumption.  The device also incorporates a wide range of digital and analogue peripherals for the user to connect to their application.
