The MAX32625/MAX32626 microcontrollers from Maxim Integrated are in stock at Mouser Electronics . The devices are based on the 32-bit RISC ARMCortex-M4F microcontroller with a floating point unit (FPU), and are ideally suited for medical and fitness applications. Both devices include 512MBytes of flash and 160kBytes of SRAM, with the architecture combining high-efficiency signal-processing functionality with low cost and ease of use.
The MAX32626 is a secure version of the MAX32625, incorporating a trust protection unit (TPU) with advanced security features.
The microcontrollers feature four powerful and flexible ultra-low-power modes for use in rechargeable devices. The microcontrollers' built-in dynamic clock gating and firmware-controlled power gating minimise power consumption for any application.
Multiple SPI, UART, and I2C serial interfaces, and a Maxim Integrated 1-Wire master and USB, allow for interconnection to a wide variety of external sensors. The microcontrollers also feature a four-input, 10-bit analog-to-digital converter (ADC) with two 5.5V-tolerant inputs, making them suitable for monitoring batteries.
The microcontrollers are supported by the MAX32625 evaluation kit, which provides a complete, functional system ideal for developing and debugging applications. The board includes many user-selectable options as well as on-board peripherals such as a Bluetooth low energy transceiver, OLED display, and indicator LEDs.
Maxim MAX32625/MAX32626 microcontrollers are available from Mouser in a 3.0mm × 3.9mm, 0.4mm-pitch, 63-ball WLP to minimise board space. The microcontrollers are ideal for small, low-power products, including sport watches, fitness monitors, wearable medical patches, portable medical devices, and sensor hubs.
