The JN5148-001 is an ultra low power, high performance
wireless microcontroller targeted at 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.
