IEEE802.15.4 wireless microcontroller with 64 kB Flash, 8 kB RAM

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 leader or follower, 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.
