NXP JN5148-001手持医疗保健设备开发方案 - 医疗电子 - 电子工程

NXP 公司的JN是超低功耗高性能无线微控制器(MCU),具有32位RISC处理器特性,还集成了2.4GHz IEEE802.15.4兼容的收发器,128KB ROM,128KB RAM和各种丰富的模拟与数字外设,可以运行JenNet和ZigBee PRO收发器的数据速率500和667kbps,工作电压2.0V-3.6V,MCU的时钟速率4- 32MHz主要用在机器人和安全低功耗无线应用,JenNet和ZigBee PRO络,智能计量,家庭和商业建筑物自动化,工业系统,遥控,手持医疗保健设备,玩具和游戏外设等本文介绍了JN主要特性和优势,功能框图,无线电框图,调制解调器框图和基带处理器框图,参考模块电路图和材料清单以及采用JN5148的手持医疗保健设备框图

The JN 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.
