NXP SSL21082, TEA1721和JN5148遥控11W LED驱动参考设计NXP公司的遥控非隔离11W LED驱动参考设计采用SSL21082, TEA1721和 JN5148.设计采用降压拓扑而不提供绝缘,采用2.4GHz RF遥控亮度和开/关.本文主要介绍JN5148-001 IEEE802.15.4无线MCU主要特性,方框图,相关的应用定路以及11W LED驱动器参考设计主要特性,完整电路图和相应部分材料清单.The JN5148-001 is an IEEE802.15.4 wireless microcontroller that provides a fully integrated solution for applications using the IEEE802.15.4 standard in the 2.4 - 2.5GHz ISM frequency band [1], including JenNet and ZigBee PRO. It includes all of the functionality required to meet the IEEE802.15.4, JenNet and ZigBee PRO specifications and has additional processor capability to run a wide range of applications including, but not limited to Smart Energy, Automatic Meter Reading, Remote Control, Home and Building Automation, Toys and Gaming.?The JN5148-001 is an ultra low power, high performance wireless microcontroller targeted at JenNet and ZigBee PRO networking applications. The device features an enhanced 32-bit RISC processor 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 2.4GHz IEEE802.15.4 compliant transceiver, 128kB of ROM, 128kB of RAM, and a rich mix of analogue and digital peripherals. The large memory footprint allows the device to run both a network stack (e.g. ZigBee PRO) and an embedded application or in a co-processor mode. The operating current is below 18mA, allowing operation direct from a coin cell.?Enhanced peripherals include low power pulse counters running in sleep mode designed for pulse counting in AMR applications and a unique Time of Flight ranging engine, allowing accurate location services to be implemented on wireless sensor networks. It also includes a 4-wire I2S audio interface, to interface directly to mainstream audio CODECs, as well as conventional MCU peripherals.?Applications that transfer data wirelessly tend to be more complex than wired ones. Wireless protocols make stringent demands on
