Analog Devices ADuCM4050 microcontroller

Tuesday, 04 December, 2018 | Supplied by: Mouser Electronics (Hong Kong) Ltd

The ADuCM4050 microcontroller, from Analog Devices, is an ultralow-power device featuring integrated power management and SensorStrobe technology to enable high system-level power savings for extended battery life in Internet of Things (IoT) edge node applications.

The microcontroller is based on an Arm Cortex-M4 core with floating-point unit, 128 KB of embedded SRAM and 512 KB of embedded flash memory. It offers a collection of digital peripherals, including three SPI interfaces, two UARTs and an I²C interface, plus up to 51 programmable general-purpose input/outputs (GPIOs). The microcontroller’s analog subsystem provides clocking, reset and power management capabilities, as well as a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC).

The device offers 40 μA/MHz active-mode consumption (680 nA in hibernate mode) for IoT applications where power consumption, security and robustness are key requirements. The microcontroller features AES 128/256, SHA 256, block ciphers for code protection, key wrap and hash message authentication code (HMAC) encryption to provide strong IP protection and defence against malware and misuse.

The product targets applications that require long battery life as well as security and performance integrity. To help devices achieve long battery life, the microcontroller incorporates SensorStrobe technology, which enables the device to collect internal and external sensor data during hibernate mode. This low-power, efficient sampling saves significant power over the long term.
