Product Details

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 also tough enough to withstand the most advanced cyberattacks. DARWIN microcontrollers are designed to run any application imaginable—in places where you wouldn’t dream of sending other microcontrollers.

Generation U microcontrollers are perfect for wearables and IoT applications that cannot afford to compromise power or performance. The MAX32625/MAX32626 feature an Arm^® Cortex^®-M4 with FPU CPU that delivers high-efficiency signal processing, ultra-low power consumption and ease of use.

Flexible power modes, an intelligent PMU, and dynamic clock and power gating optimize performance and power consumption for each application. Internal oscillators run at 96MHz for high-performance or 4MHz to maximize battery life in applications requiring always-on monitoring.

Multiple SPI, UART, I²C, 1-Wire® master, and USB interfaces are provided. The four-input, 10-bit ADC with selectable references can monitor external sensors.

All versions provide a hardware AES engine. The MAX32626 provides a secure trust protection unit (TPU) with a modular arithmetic accelerator (MAA) for fast ECDSA, a hardware PRNG entropy generator, and a secure boot loader. The MAX32625L provides a reduced 256kB of flash memory and 128kB of SRAM.

MAXPICO2PMB

View Detailed Evaluation Kit Information

The MAXPICO2PMB adapter board is a fully assembled and tested PCB that provides an I²C interface to quickly interact with an evaluation kit (EV kit) or a demo board connected through the Pmod™ connector.

The adapter board features a rapid development platform - the MAX32625PICO microcontroller, jumpers and a Pmod connector. The user can select on-board pullup resistors on the I²C lines by configuring jumpers. It also features an option to select the pullup voltage for the I²C lines through the power rail jumper. The Pmod connector provides one I²C port and two SPI ports for convenient evaluation.

The MAXPICO2PMB Register Map Tool is a Windows application that interfaces with the MAXPICO2PMB adapter board. The user can import *.regmap files that contain the unique I²C register map information and register field descriptions of an integrated circuit. The application sends commands to the MAX32625PICO microcontroller on the MAXPICO2PMB adapter board over a virtual serial port. The MAX32625PICO microcontroller sends I²C commands to communicate with the EV kit or demo board connected through the Pmod connector.
