JN5168/001,518

MCU, 无线微控制器, 32 MHz, 32位, 32 KB RAM/256 KB编程, I2C, SPI, UART, HVQFN-40

Overview

The JN5168 is an ultra low power, high performance wireless microcontroller supporting ZigBee and IEEE802.15.4 networking stacks to facilitate the development of Smart Energy, Home Automation, Smart Lighting and wireless sensor applications. It features an enhanced 32-bit RISC processor with 256 kB embedded Flash, 32 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 best in class 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 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.
