JN5179/001Z

ZigBee and IEEE802.15.4 Wireless Microcontroller with 512KB Flash, 32KB RAM

Overview

The JN5179 device is an ultra-low-power, high-performance wireless microcontroller, optimized as a platform for ZigBee 3.0 applications in Smart Home and Smart Lighting networks. It features an ARM Cortex-M3 processor with debug and programmable clock speeds. The JN5179 device has 512 kB of embedded Flash memory as well as 32 kB of RAM and 4 kB of EEPROM. The embedded Flash can support "Over-The-Air" firmware updates. The device also includes a 2.4 GHz "IEEE802.15.4 compliant" transceiver and a comprehensive mix of on-chip analog and digital peripherals.

The radio transmit power is configurable up to +10 dBm output. The very-low receive operating current down to 12.7 mA in normal operation and 0.6 µA in sleep mode results in long battery life, allowing operation directly from a coin cell. Through its power-saving modes, the device is therefore ideal for battery-powered nodes. The on-chip peripherals include a fail-safe I2C-bus, SPI-bus ports both master and slave and a 6-channel analog-to-digital converter, directly supporting a wide range of applications without the need for extra hardware.
