IEEE802.15.4 Wireless Microcontroller
Overview
The JN516x series is a range of ultra low power, high performance wireless microcontrollers supporting JenNet-IP, ZigBee PRO or RF4CE networking stacks to facilitate the development of Home Automation, Smart Energy, Light Link and Remote control applications. They feature an enhanced 32bit RISC processor with embedded Flash and EEPROM memory, offering high coding efficiency through variable width instructions, a multi-stage instruction pipeline and low power operation with programmable clock speeds. They also include a 2.4GHz IEEE802.15.4 compliant transceiver and a comprehensive mix of analogue and digital peripherals. Three memory configurations are available to suit different applications. The best in class operating current of 15mA, with a 0.6uA 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 master or slave, 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.
