General Description

The MAX32630/MAX32631 is an ARM® Cortex® -M4F

32-bit microcontroller with a floating point unit, ideal for

the emerging category of wearable medical and fitness

applications. The architecture combines ultra-low power

high-efficiency signal processing functionality with signifi-

cantly reduced power consumption and ease of use. The

device features 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 clock gating

and firmware-controlled power gating allows the user to

optimize power for the specific application. Multiple SPI,

UART and I2C serial interfaces, as well as 1-Wire® mas-

ter and USB, allow for interconnection to a wide variety of

external sensors. A four-input, 10-bit ADC with selectable

references is available to monitor analog input from exter-

nal sensors and meters. The small 100-ball WLP package

provides a tiny, 4.37mm x 4.37mm footprint.

The MAX32630/MAX32631 include a hardware AES

engine. The MAX32631 is a secure version of the

MAX32630. It incorporates a trust protection unit (TPU)

with encryption and advanced security features. These

features include a modular arithmetic accelerator (MAA)

for fast ECDSA, a hardware PRNG entropy generator,

and a secure boot loader.
