Data Sheet – JN5121
IEEE802.15.4 Wireless Microcontroller
Overview
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.
