MAX32665–MAX32668
Low-Power Arm Cortex-M4 with FPU-Based
Microcontroller with Bluetooth 5 for Wearables
General Description
DARWIN is a new breed of low-power microcontrollers
built to thrive in the rapidly evolving Internet of Things
(IoT). They are smart, with the biggest memories in their
class and a massively scalable memory architecture. They
run forever, thanks to wearable-grade power technology.
They are durable enough to withstand the most advanced
cyberattacks. DARWIN microcontrollers are designed to
run any application imaginable—in places where you
would not dream of sending other microcontrollers.
Generation UB microcontrollers are designed to handle
the increasingly complex applications demanded by to-
day's advanced battery-powered devices and wirelessly
connected devices, while providing robust hardware secu-
rity and Bluetooth® 5 Low Energy (BLE) radio connectivi-
ty.
The MAX32665-MAX32668 UB class microcontrollers are
advanced systems-on-chips featuring an Arm® Cor-
tex®-M4 with FPU CPU for efficient computation of com-
plex functions and algorithms with integrated power man-
agement. It also includes the newest generation Bluetooth
5 Low Energy radio with support for long range (4x) and
high throughput (2Mbps) and Maxim's best-in-class hard-
ware security suite trust protection unit (TPU). The de-
vices offer large on-board memory with 1MB flash and up
to 560KB SRAM that can be configured as 448KB SRAM
with error correction coding (ECC). Split flash banks of
512KB each support seamless over the air upgrades,
adding an additional degree of reliability. Memory scalabil-
ity of data (SRAM) and code (Flash) space is supported
by two SPI execute-in-place (SPIX) interfaces.
Multiple high-speed interfaces are supported including
HS-USB, secure digital interface (SD, SDIO, MMC, SD-
HC, and microSD™), SPI, UART, and I2C serial inter-
faces, and an audio subsystem supporting PDM, PCM,
I2S, and TDM interfaces. An 8-input, 10-bit ADC is avail-
able to monitor analog inputs from external sensors and
meters. The devices are available in 109-bump WLP
(0.35mm pitch) and 121-bump CTBGA (0.65mm pitch).
