Product details
Overview
K32W148-EVK from NXP Semiconductors is an evaluation kit for the K32W148 wireless MCU, supporting concurrent Wi-Fi 4 (802.11n), Bluetooth 5.0, and IEEE 802.15.4 (Thread/Zigbee) operation on a single M.2 Key E form factor. It integrates SDIO, UART, SPI, I²C, PCM, and sideband control interfaces, and targets secure IoT edge node development with hardware-accelerated cryptographic engines and TrustZone-enabled secure boot.
For engineers reviewing the K32W148-EVK datasheet, K32W148-EVK pinout, K32W148-EVK application, or K32W148-EVK equivalent, this page provides verified interface definitions, Tri-Radio signal mapping, I/O expander configuration (PCAL6408A), coexistence (COEX) routing guidance, and JTAG debug support per AN13049 Rev. 6.0.
Technical Context
The K32W148-EVK implements NXP's Tri-Radio architecture using an M.2 Key E connector with dedicated SDIO (Wi-Fi), UART (Bluetooth), and SPI (802.15.4) host interfaces. Sideband signals-including WL_WAKE_IN, BT_WAKE_IN, IND_RST_WL, IND_RST_BT, and IND_RST_15.4-are routed via GPIOs and an I²C-controlled PCAL6408A I/O expander (I²C address 0x20).
Coexistence is managed through three COEX pins (COEX1–COEX3) supporting PTA and dual-UART protocols, while audio timing uses PCM_SYNC and I²S/PCM interfaces. JTAG_TDI/TDO/TCK/TMS signals are brought out to test pads or a Hirose FH12-10S-0.5SH(55) connector for firmware development and debugging.

FAQ
What is the primary function of the K32W148-EVK?
The K32W148-EVK is an evaluation kit enabling rapid prototyping and validation of the K32W148 wireless MCU. It provides full access to all Tri-Radio interfaces-Wi-Fi via SDIO, Bluetooth via UART, and 802.15.4 via SPI-alongside sideband control, COEX, JTAG, and audio signals. Engineers use the K32W148-EVK to verify system-level integration before final PCB design.
Which M.2 key and revision does the K32W148-EVK follow?
The K32W148-EVK uses M.2 Key E (2230) and adheres to PCI-SIG M.2 Specification Rev. 3.0 for Tri-Radio signal definitions, as confirmed in AN13049 Rev. 6.0. Using Rev. 4.0 definitions for SPI signals will prevent proper 802.15.4 transceiver operation, though Wi-Fi and Bluetooth remain functional.
How is sideband control implemented on the K32W148-EVK?
Sideband control on the K32W148-EVK uses both direct GPIO connections (e.g., WL_WAKE_IN on Pin 40, BT_WAKE_IN on Pin 42) and an I²C-based NXP PCAL6408A I/O expander (address 0x20) for Tri-Radio-specific signals including IND_RST_15.4 (P1), BT_15.4_WAKE_IN (P3), and NB2_WAKE_IN (P5). Pull-up/pull-down requirements are defined per signal type.
Does the K32W148-EVK support coexistence between wireless protocols?
Yes-the K32W148-EVK supports hardware coexistence via three dedicated COEX pins (COEX1–COEX3) configured for PTA (Priority-Based Traffic Arbitration) and second-UART protocols. These pins route external radio request (EXT_REQ), priority (EXT_PRI), and grant (EXT_GNT) signals, enabling deterministic arbitration among Wi-Fi, Bluetooth, and 802.15.4 radios.
What debug interface options does the K32W148-EVK provide?
The K32W148-EVK provides full JTAG debug capability via JTAG_TDI, JTAG_TDO, JTAG_TCK, and JTAG_TMS signals, routed to either test pads or a Hirose FH12-10S-0.5SH(55) connector. This enables firmware development, real-time tracing, and secure bootloader debugging directly on the K32W148-EVK without requiring additional adapter hardware.
