MAX32630/MAX32631
EVALUATION KIT AVAILABLE
Ultra-Low Power, High-Performance
Cortex-M4F Microcontroller for Wearables
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.
