Analog Devices / Maxim Integrated MAX32625 & MAX32626 32-Bit MCUs

Analog Devices MAX32625 and MAX32626 Arm^® Cortex^®-M4F 32-Bit Microcontrollers are ideal for the emerging wearable medical and fitness applications category. The architecture combines ultra-low power, high-efficiency signal processing functionality, and ease of use. An internal 96MHz oscillator provides high-performance capability. The internal 4MHz oscillator supports minimal power consumption for applications requiring always-on monitoring.

The MAX32625 and MAX32626 MCUs provide 512kB of flash and 160kB of SRAM. These devices feature four powerful and flexible power modes. A peripheral management unit (PMU) enables intelligent peripheral control with up to six channels to significantly reduce power consumption. Built-in dynamic and firmware-controlled clock gating allows users to optimize power for the specific application.

The Analog Devices MAX32625 and MAX32626 MCUs are available in WLP-63 and TQFN-EP-68 packages with a -30°C to +85°C operating temperature range.
