Maxim Microcontrollers
Maxim Integrated, now part of Analog Devices, developed the MAX32 series of microcontrollers that combine ARM Cortex-M processors with best-in-class analog integration, power management, and security features. These compact, highly integrated MCUs are purpose-built for wearable health and fitness devices, IoT sensor nodes, and applications where board space, battery life, and data security are critical design considerations.

Frequently Asked Questions
DARWIN is Maxim's family of secure microcontrollers designed for IoT, financial, and industrial applications requiring the highest level of security. ChipDNA is a physically unclonable function (PUF) technology that generates unique cryptographic keys from naturally occurring random variations in semiconductor manufacturing. Unlike stored keys, ChipDNA keys are generated on-demand and never exist in memory, making them immune to invasive probing or reverse engineering attacks.
Maxim microcontrollers integrate a complete power management subsystem including SIMO buck-boost regulators, LDOs, battery charger, and fuel gauge directly on the MCU die. The SIMO technology generates multiple voltage rails from a single inductor, dramatically reducing external component count and PCB area. This level of integration can eliminate 10 or more discrete power components, reducing total solution size by up to 50% compared to traditional MCU plus external PMIC designs.
Yes. Following the 2021 acquisition by Analog Devices, the MAX32 microcontroller families continue to be manufactured, supported, and developed. The product lines have been integrated into the Analog Devices portfolio with continued investment in new devices. Level Solutions can source both current and legacy Maxim MCU part numbers with full authentication and traceability.
Several MAX32 family members integrate Bluetooth Low Energy (BLE 5.0/5.2) transceivers directly on-chip, including the MAX32655 and MAX32665. These devices include the complete RF front-end with on-chip antenna matching network, requiring no external RF components in many designs. This single-chip wireless solution is ideal for wearable health monitors, fitness trackers, and IoT sensor nodes that need low-power wireless connectivity.
