Compact 32-bit microcontrollers target emerging medical and fitness applications

Mouser has announced it is now stocking Maxim's MAX32620/MAX32621 microcontroller duo, based on the 32-bit RISC ARM Cortex-M4F microcontroller with a floating point unit (FPU), they are ideally suited to emerging medical and fitness applications, says the company. Both devices include 2MBytes of flash and 256kbits of SRAM, with the architecture combining high-efficiency signal-processing functionality with low cost, and ease of use. The MAX32621 is a secure version of the MAX32620, incorporating a trust protection unit (TPU) with encryption and advanced security features. Maxim Integrated MAX3262x microcontrollers, now available from Mouser Electronics, feature four powerful and flexible ultra-low-power modes (LP0 - LP3) for use in rechargeable devices. The microcontrollers' built-in dynamic clock gating and firmware-controlled power gating minimize 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 selectable references. Maxim MAX3262X microcontrollers are available from Mouser in a 3.9mm × 3.9mm, 0.4mm pitch, 81-ball WLP to minimize 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.
