The MAX28200 is a low-power， 16-bit MAXQ? microcontroller （μC） designed for low-power applications， including smart phones and consumer electronics. The device combines a powerful 16-bit RISC microcontroller with a 10-bit， 93.75ksps ADC along with an I2C communications port. The device includes four GPIO pins. The device includes 16KB of flash memory and 2KB of data SRAM. Additional utility ROM space includes macros such as an I2C bootloader to enable flash memory firmware updates in the field. The device provides NIST SP 800-185 compliant secure hash algorithm （SHA-3） KMAC challenge and response authentication and can be paired with other SHA-3 devices.

For the ultimate in low-power battery-operated performance， the device includes an ultra-low-power stop mode. In this mode， the minimum amount of circuitry is powered. The device wakes up on a matching I2C address. Wake-up sources also include external interrupts， the power-fail warning， and a wake-up timer interrupts. The microcontroller runs from a wide 1.71V to 3.63V operating voltage.
