High Performance and Ultra-Low-Power MCU for Zigbee®,Thread, and Bluetooth LE 5.0 with Built-in NFC option

The K32W0x portfolio is designed to power the next generation of

ultra-low-current multiprotocol wireless IoT devices with support for Matter,

IEEE 802.15.4 mesh network protocols Zigbee and Thread and Bluetooth Low

Energy 5.0. The K32W041AM/A are compatible with the K32W061/41.

The K32W041AM and K32W041A family members support longer range and expanded

memory optimized to facilitate home and building automation, smart lighting,

smart locks, gateways, and routers.

The K32W041A/K32W041AM 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. With 640 KB embedded Flash, 152 KB RAM memory, additional 1 MB

data Flash with the K32W041AM, and support for Over-the-Air (OTA) updates, the

K32W0x family provides scalability to address a variety of memory

requirements. In addition, the K32W041AM/A extends the wireless radio output

power to +15dBm.

These devices include a 10-channel PWM, two timers, one RTC/alarm timer, a

Windowed Watchdog Timer (WWDT), two USARTs, two SPI interfaces, two I²C

interfaces, a DMIC subsystem including a dual-channel PDM microphone interface

with voice activity detector, one 12-bit ADC, temperature sensor and a

comparator. The Arm Cortex-M4 is a 32-bit core operating at u to 48MHz that

offers system enhancements such as low power consumption, enhanced debug

features, and a high-level support of the block integration.

Devices across the K32W0x, JN18x and QN90x0 families are supported with common

software stacks: Zigbee, OpenThread and Bluetooth LE.
