Data Sheet: JN5148-001
IEEE802.15.4 Wireless Microcontroller
Overview
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.
