Product details
Overview
MAX32625IWYL+T from Maxim Integrated is an ultra-low-power Arm® Cortex®-M4 with FPU microcontroller designed for wearable and IoT edge nodes. It features 512KB flash, 160KB SRAM, 96MHz/4MHz dual-clock system, 10-bit delta-sigma ADC (7.8ksps), and hardware AES-128/-192/-256 encryption - enabling secure, always-on physiological monitoring in sports watches and medical patches.
For engineers reviewing the MAX32625IWYL+T datasheet, MAX32625IWYL+T pinout, MAX32625IWYL+T application, or MAX32625IWYL+T equivalent, this page delivers verified technical context, low-power mode timing, peripheral interface mapping, and real-world selection guidance for battery-constrained embedded designs.
Technical Context
The MAX32625IWYL+T implements a dual-oscillator clock architecture: a factory-trimmed 96MHz internal relaxation oscillator (±0.24% over temperature) for high-performance execution, and a 4MHz RC oscillator optimized for sub-50μA/MHz active current in LP2 mode. Its Peripheral Management Unit (PMU) enables dynamic clock/power gating across six independent domains.
It integrates a 10-bit delta-sigma ADC with selectable input ranges (0.05–5.5V), programmable gain, and ±2 LSB INL; a full-speed USB 2.0 device controller with integrated transceiver and 3.3V VDDB supply; and three SPI masters, two I²C masters, three UARTs, and a 1-Wire master - all accessible via up to 40 GPIO pins with individually configurable VDDIO/VDDIOH supplies.

FAQ
What is the maximum operating frequency of the MAX32625IWYL+T CPU core?
The MAX32625IWYL+T features an Arm Cortex-M4 with FPU core that operates at up to 96MHz using its factory-trimmed internal relaxation oscillator. This frequency is USB-compliant (95.76–96.24MHz) and supports high-efficiency signal processing for sensor fusion algorithms without requiring an external crystal.
Does the MAX32625IWYL+T support hardware-based AES encryption?
Yes, the MAX32625IWYL+T includes a dedicated hardware AES engine supporting AES-128, AES-192, and AES-256 block cipher modes. This accelerator offloads encryption/decryption tasks from the CPU, enabling secure BLE packet handling and firmware image authentication with deterministic timing.
What package type and dimensions does the MAX32625IWYL+T use?
The MAX32625IWYL+T is packaged in a 63-ball Wafer-Level Package (WLP) measuring 3.3mm × 3.3mm with 0.4mm ball pitch. This ultra-compact, RoHS-compliant package is optimized for space-constrained wearable designs and supports fine-pitch PCB assembly.
How does the MAX32625IWYL+T achieve ultra-low power consumption in sleep modes?
The MAX32625IWYL+T achieves 600nA in LP0 mode (RTC active) and 2.56μW in LP1 retention mode through a combination of intelligent PMU-controlled domain gating, 1.2V core regulation, and optimized clock tree design. Its 5μs wake-up from LP1 enables rapid response to sensor interrupts without sacrificing energy efficiency.
Can the MAX32625IWYL+T interface directly with 3.3V sensors and peripherals?
Yes, the MAX32625IWYL+T supports dual I/O voltage rails: VDDIO (1.71–3.6V) and VDDIOH (≥VDDIO). By configuring VDDIOH = 3.3V, up to 40 GPIO pins can safely interface with 3.3V sensors, displays, or communication peripherals without level shifters - simplifying system design and reducing BOM cost.
