Analog Devices / Maxim Integrated MAX32621 Secure Arm® Cortex®-M4 Microcontrollers

Analog Devices MAX32621 Secure Arm® Cortex®-M4 Microcontrollers incorporate a trust protection unit (TPU) with encryption and advanced security features. This makes the MAX32621 ideal for medical and fitness applications and wearable devices. Security features include a modular arithmetic accelerator (MAA) for ECDSA, a true random number generator (TRNG), and a secure boot loader. The MAX32621 combines high-efficiency signal-processing functionality with low cost, aiding in ease of use. Connecting to a broad variety of external sensors, the MAX32621 has multiple serial interfaces, including SPI, UART, and I2C. The Analog Devices MAX32621 provides high-performance capability through an internal 96MHz oscillator and supports minimal power consumption for applications requiring always-on monitoring through an additional internal 4MHz oscillator.
