MM32F0020B1T

The MM32F0020 microcontroller is built around an Arm Cortex-M0 core, with a maximum operating frequency of 48MHz. It features 32KB of high-speed flash memory and integrates a rich set of I/O ports and peripheral modules. This product includes 1 x 12-bit ADC, 1 x 16-bit advanced timer, 1 x 16-bit general-purpose timer, and 1 x 16-bit basic timer, along with standard communication interfaces: 1 x I2C, 1 x SPI or I2S, and 2 x UART. The operating voltage range is 2.0V ~ 5.5V, with operating temperature ranges (ambient) of -40℃ ~ +85℃ for the industrial grade and -40℃ ~ +105℃ for the extended industrial grade (suffix V). Multiple built-in power-saving modes ensure the requirements of low-power applications are met. The product is available in QFN20 and TSSOP20 package options.
