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.

低成本手持醫(yī)療保健設(shè)備
Portable healthcare devices help monitor vital signs, restart the heart, and look inside the body with ultrasound before the patient is taken to the hospital. NXP’s goal is to contribute to home healthcare devices that are easy to use, interoperable and offer diagnostic value so that insurance will cover the cost. This eliminates the need for a hospital visit or stay and reduces healthcare costs.
Many consumer medical devices today simply display health monitoring results and leave the interpretation and logging to end users and their doctors, newer devices feature simple connectivity to log and transmit results automatically. Connectivity is either wired, wireless or combined.
NXP helps you succeed in the increasingly competitive home health care market, helping consumer medical devices offer the following features:
手持醫(yī)療保健設(shè)備特性：
Ease of use
Highly reliable and safe (government-regulated) operation
Easy, secure connectivity
Low-power operation (i.e. long battery life)
Support for a wide range of voltages (especially lower voltages)
High measurement accuracy
Small form factors
Affordable cost
