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.
