JN5148 Wireless Microcontroller
The JN5148 is our latest generation of ultra-low-power, low-cost wireless microcontroller for wireless sensor networking applications based on the IEEE802.15.4 standard, including JenNet, JenNet-IP and ZigBee PRO applications.
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 mean that the device offers many new and innovative peripheral enhancements, such as:
- 4-wire digital audio interface that will connect directly to mainstream audio CODECs
- Low-power sleep counters designed for pulse counting in AMR applications
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.
