Product details

Overview

USB-KW24D512 from NXP (formerly Freescale) is a USB-form-factor packet sniffer and reprogrammable development dongle built around the MKW24D512 wireless MCU. It delivers IEEE 802.15.4 packet capture at -102 dBm RX sensitivity, +8 dBm TX output, and supports dual PAN operation for concurrent RF network monitoring - used with BeeKit Test Tool Protocol Analyzer and commercial 802.15.4 sniffers.

For engineers reviewing the USB-KW24D512 datasheet, USB-KW24D512 pinout, USB-KW24D512 application, or USB-KW24D512 equivalent, this page provides verified hardware identity, firmware flexibility (sniffer vs. node), USB 2.0 FS/LS interface, JTAG debug access, and confirmed operating range (1.7–3.6 V, –40°C to +105°C).

Technical Context

The USB-KW24D512 integrates the MKW24D512 SoC - a 50 MHz ARM Cortex-M4 MCU with integrated 2.4 GHz IEEE 802.15.4 transceiver, 512 KB Flash, 64 KB SRAM, and hardware crypto engine (AES-128/256, SHA-256, RNG). It operates as a standalone USB HID-class device with virtual COM port enumeration.

Its dual PAN support enables simultaneous monitoring of two independent 802.15.4 networks without software switching. The onboard antenna, reset/application buttons, and mini-JTAG (10-pin) connector provide direct hardware control and firmware reprogramming capability for protocol stack validation or custom node deployment.

FAQ

What is the primary function of the USB-KW24D512?

The USB-KW24D512 is a pre-programmed USB dongle that functions as an IEEE 802.15.4 packet sniffer for over-the-air wireless traffic monitoring. It can also be reprogrammed as a development board or network node using the MKW24D512 SoC. Its default firmware interfaces directly with Freescale's BeeKit Test Tool Protocol Analyzer and supports MAC and ZigBee RF4CE packet decoding.

Does the USB-KW24D512 require external power or drivers?

The USB-KW24D512 draws power directly from the host USB port (5 VDC) and requires no external supply. Windows automatically installs its CDC ACM virtual COM port driver upon first connection; alternatively, drivers are included in the BeeKit Wireless Connectivity Toolkit installation folder. No additional hardware power source is needed for standard sniffer operation.

Can the USB-KW24D512 be used with protocols beyond ZigBee?

Yes - the USB-KW24D512 supports any IEEE 802.15.4-based protocol stack, including Thread, RF4CE, and proprietary MAC layers, because it exposes raw 802.15.4 frames via the Test Tool API. Its dual PAN hardware allows concurrent monitoring of multiple logical networks, making it suitable for interoperability testing across ZigBee, Thread, and custom PHY/MAC implementations.

How is firmware updated on the USB-KW24D512?

Firmware on the USB-KW24D512 is updated via its 10-pin mini-JTAG interface using either the BeeKit Test Tool's Kinetis Firmware Loader or IAR Embedded Workbench with a J-Link programmer. The device must be placed in bootloader mode (via reset sequence or JTAG), then programmed with SREC files targeting the MKW24D512 flash memory map - no USB-based DFU is supported in stock configuration.

What debugging interfaces does the USB-KW24D512 provide?

The USB-KW24D512 provides a 10-pin mini-JTAG interface compatible with standard J-Link debug probes for full SWD-based debugging, flash programming, and real-time register inspection. It does not include SWD-only or CMSIS-DAP interfaces. The onboard Reset and Application buttons support manual firmware reset and user-defined trigger events during development.
