NXP Semiconductors K32W041A & K32W041AM Wireless Microcontrollers
NXP Semiconductors K32W041A and K32W041AM Wireless Microcontrollers are ultra-low power high-performance Arm® Cortex®-M4 based MCUs supporting Zigbee 3.0, Thread, and BLUETOOTH® Low Energy 5.0. The K32W041A and K32W041AM MCUs are optimized for home and building automation, smart lighting, smart locks, and sensor network applications.
The K32W041A and K32W041AM Wireless MCUs include a 2.4GHz Bluetooth Low Energy (BLE) 5 transceiver supporting eight simultaneous connections. The devices also integrate a 2.4GHz IEEE 802.15.4 transceiver and a comprehensive mix of analog and digital peripherals. Ultra-low current consumption in transmit, receive, and power-down modes allow these devices to be used in applications powered by coin cell batteries.
The K32W041A and K32W041AM have 640KB embedded Flash, 152KB RAM memory, and offer radio output power of +15dBm. The K32W041AM has an additional 1MB Data Flash. The embedded Flash can support Over The Air (OTA) code download for applications. The devices include a 10-channel PWM, two timers, one RTC/alarm timer, and a Windowed Watchdog Timer (WWDT). Additional features include two USARTs, two SPI interfaces, two I2C interfaces, one 12-bit ADC, a temperature sensor, and a comparator. An integrated DMIC subsystem offers a dual-channel PDM microphone interface with a voice activity detector.
The 32-bit Arm Cortex-M4 core offers system enhancements such as low power consumption, enhanced debug features, and high-level support of the block integration. The Arm Cortex-M4 CPU operates at up to 48MHz.
