JN5148 Wireless Microcontroller - ZigBee PRO Platform
The JN5148 launches Jennic's latest generation of ultra low power, low cost wireless microcontrollers for wireless sensor networking applications based on the IEEE802.15.4 standard, including ZigBee PRO.
It offers an enhanced 32-bit RISC processor featuring improved coding efficiency and up to 32MIPs performance, a fully compliant 2.4GHz IEEE802.15.4 transceiver, 128kB of ROM and 128kB of RAM to support both the networking protocol stack and user application on-chip, and a rich mix of user peripherals.
The 32-bit RISC CPU achieves world class performance through its variable instruction width, multi-stage instruction pipeline and prioritised interrupt scheduler.
The highest levels of on-chip integration also means that the device offers many new and innovative peripheral enhancements, such as:
o 4-wire digital audio interface that will connect directly to mainstream audio CODECs
o Low power sleep counters designed for pulse counting in AMR applications
o Time of Flight (TOF) ranging engine (with patent pending) for use in location aware systems based on IEEE802.15.4
The JN5148 sets new benchmarks for the lowest power consumption, highest processing capability and the highest levels of integration in a single chip wireless microcontroller.
Ultra Low Power Consumption
The integrated power management on the JN5148 efficiently controls the system power, enabling it to support applications that require the use of a coin cell with a 20mA limited discharge capability. With a system operating current consumption of 18mA when receiving, and 15mA when transmitting at +3dBm, the JN5148 consumes typically 35% less power than existing solutions in these modes of operation.
ZigBee PRO Ready
The JN5148 is Jennic's ZigBee PRO platform. The combination of 128kB ROM, 128kB RAM and the 32-bit RISC CPU ensure that it is able to cover the complete spectrum of ZigBee PRO applications, with stack and application integrated in a single chip solution. Furthermore, with support for co-processor configurations it enables the addition of ZigBee PRO functionality to existing applications processors with complete ease and speed of implementation.
Together, the combination of Jennic's JN5148 wireless microcontroller with Jennic's ZigBee PRO networking stack have been certified as a ZigBee Compliant Platform (ZCP).
