What the MSPM0G3505 does
The MSPM0G350x family comprises ultra-low-power 32-bit mixed-signal microcontrollers featuring an Arm Cortex-M0+ core operating up to 80MHz. The specific variants, MSPM0G3505, MSPM0G3506, and MSPM0G3507, span memory configurations from 32KB to 128KB flash. These devices operate on a 1.62V to 3.6V supply, support extended temperatures from -40°C to 125°C, and consume as little as 1.5µA in standby mode. They integrate high-performance analog peripherals including two 12-bit 4Msps ADCs, a 12-bit DAC, and two zero-drift op-amps. Typically used in motor control, smart metering, and factory automation, these MCUs combine extensive digital interfaces like CAN-FD and UART with robust data integrity features to meet diverse industrial and consumer application requirements.
