K32W061/K32W041 IEEE 802.15.4 and Bluetooth LE 5.0 wireless microcontroller Rev. 1.3 May 2021 Product data sheet 1. General description The K32W061 and K32W041 (called K32W061 throughout this document) are ultra-low power, high performance Arm Cortex -M4 based wireless microcontrollers supporting Zigbee 3.0, Thread and Bluetooth Low Energy 5.0 networking stacks to facilitate home and building automation, smart lighting, smart locks and sensor network applications. The K32W061 includes a 2.4 GHz Bluetooth Low Energy 5 (supporting eight simultaneous connections) compliant transceiver, a 2.4 GHz IEEE 802.15.4 compliant transceiver and a comprehensive mix of analog and digital peripherals. Ultra-low current consumption in both radio receive and transmit modes and also in the power down modes allow use of coin cell batteries. The product has 640 KB embedded Flash and 152 KB RAM memory. The embedded flash can support Over The Air (OTA) code download to applications. The devices include 10-channel PWM, two timers, one RTC/alarm timer, a Windowed Watchdog Timer 2 (WWDT), two USARTs, two SPI interfaces, two I C interfaces, a DMIC subsystem including a dual-channel PDM microphone interface with voice activity detector, one 12-bit ADC, temperature sensor and comparator. The K32W061 variant has an internal NFC tag with connections to the external NFC antenna. The Arm Cortex-M4 is a 32-bit core that offers system enhancements such as low power consumption, enhanced debug features, and a high level support of the block integration. The Arm Cortex-M4 CPU, operates at up to 48 MHz. 2.
