The MAX32620/MAX32621 microcontrollers from Maxim Integrated are now being shipped by distributor Mouser Electronics. The devices are based on the 32-bit RISC ARM Cortex-M4F microcontroller with a floating point unit (FPU), ideally suited for the emerging category of medical and fitness applications. 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.
The microcontrollers 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.
The microcontrollers are available 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.
