Description

Create a design and simulate using EE-Sim^® tools:

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.
