16-Bit Microcontroller with ADC and I²C

Versatile, Low-Power Microcontroller Includes Dual 10-Bit ADC Channels and 4 GPIO in a Small, 1.7mm x 1.8mm Package

Please check latest availability status for a specific part variant.


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.
