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.
