The FRDM-MCXW23 offers easy evaluation of the MCX W23’s Bluetooth® Low Energy 5.3 radio capabilities. The board is ideal for prototyping battery-powered, miniature products for applications in the portable medical, home appliance, home automation, and asset tracking markets.
Equipped with a three-axis accelerometer, temperature sensor, Flash data memory and LEDs, the FRDM-MCXW23 operates from a 3 V coin cell battery via the MCX W23’s buck dc-dc converter, or from USB bus power.
The board includes an MCU-Link debugger, and Arduino, mikroBUS™ and Pmod™ headers for easy access to the MCU I/Os. Memory expansion is provided via an MX25R6435F 8 Mbyte SPI Flash device.
The FRDM-MCXW23 is backed by a rich set of software resources including:
Integrated, low-power wireless MCU
The MCX W23 is a highly integrated, Bluetooth Low Energy 5.3 wireless transceiver with embedded MCU core and Flash memory in a single chip. The ultra-low power operation of the MCX W23’s radio gives extended battery lifetime in wearable or battery-powered sensors and actuators. Featuring a high level of integration and small package options, the MCX W23 provides a cost-effective solution for wireless control circuits.
The MCX W23 features a 32 MHz Arm® Cortex®-M33 CPU core with support for a TrustZone® trusted execution environment. The CPU is backed by up to 1 Mbyte of Flash memory, 128 kbytes of RAM, and 256 kbytes of ROM. Supported by a flexible power management unit which performs both buck and boost conversion, the MCX W23 can run directly from a wide range of batteries.
The MCX W23 is part of the NXP Certified Edgelock Assurance program. It supports SESIP level 2 and PSA level 2 certification, offering the advanced security required for medical, industrial, and smart home applications.
The MCX W23 chip is supplied in a 2.63 x 2.49 mm WLCSP37, or a 40-pin QFN package which has a footprint of 5 mm x 5 mm.
