4. Overview
The JN517x is an IEEE802.15.4 wireless microcontroller that provides a fully integrated
solution for applications using the IEEE802.15.4 standard in the 2.4 GHz to 2.5 GHz ISM
frequency band, including ZigBee PRO and Thread.
Applications that transfer data wirelessly tend to be more complex than wired ones.
Wireless protocols make stringent demands on frequencies, data formats, timing of data
transfers, security and other issues. Application development must consider the
requirements of the wireless network in addition to the product functionality and user
interfaces. To minimize this complexity, NXP provides a series of software libraries and
interfaces that control the transceiver and peripherals of the JN517x. These libraries and
interfaces remove the need for the developer to understand wireless protocols and greatly
simplifies the programming complexities of power modes, interrupts and hardware
functionality.
In view of the above, it is not necessary to provide the register details of the JN517x in the
data sheet.
The device includes a wireless transceiver, ARM Cortex-M3 CPU, “on-chip memory” and
an extensive range of peripherals.
4.1 Wireless transceiver
The wireless transceiver comprises a 2.45 GHz radio, a modem, a baseband controller
and a security coprocessor. In addition, the radio also provides an output to control
transmit-receive switching of external devices such as power amplifiers allowing
applications that require increased transmit power to be realized very easily. Section 15.1
describes a complete reference design including Printed-Circuit Board (PCB) design and
Bill Of Materials (BOM).
The security coprocessor provides hardware-based 128-bit AES-CCM modes as
specified by the IEEE802.15.4 2006 standard. Specifically this includes encryption and
authentication covered by the MIC-32/-64/-128, ENC and ENC-MIC-32/-64/-128 modes of
operation.
The transceiver elements (radio, modem and baseband) work together to provide
IEEE802.15.4 (2006) MAC and PHY functionality under the control of a protocol stack.
The transmitter is equipped with a power amplifier with 3 options for transmit power (major
steps, fine steps and attenuator) see Figure 51. Applications incorporating IEEE802.15.4
