Note: JN5189/88T is preferred for any new new Zigbee®,
Thread design. No new software releases planned
The JN5161 is an ultra low power, high performance wireless microcontroller supporting ZigBee Green Power and
IEEE802.15.4 networking stacks to facilitate the development of wireless sensor applications. It features an
enhanced 32-bit RISC processor with 64 kB embedded Flash, 8 kB RAM and 4 kB EEPROM memory, offering high coding
efficiency through variable width instructions, a multi-stage instruction pipeline and low power operation with
programmable clock speeds. It also includes a 2.4 GHz IEEE802.15.4 compliant transceiver and a comprehensive mix of
analogue and digital peripherals. The very low operating current of 15 mA, with a 0.6 μA sleep timer mode,
gives excellent battery life allowing operation direct from a coin cell.
The peripherals support a wide range of applications. They include a 2-wire I²C, and SPI ports which can operate
as either , a four channel ADC with battery and a temperature sensor. It can support a large switch
matrix of up to 100 elements, or alternatively a 20 key capacitive touch pad.
